Hi everybody!

I have written a small class to help me in the design of control objects (like special buttons, sliders, drag&drop object, etc.) into Cocos2d. I was inspired by the UIControl API from the UIKit framework. I would share it with you in order to see if this could have any utility and why not improved it in order to better meet the needs of everyone.

You can find the file to my github here: https://github.com/YannickL/CCControl

To illustrate how to use it I have modified the CCSlider from the cocos2d-iphone-extensions. You can download it here: https://github.com/YannickL/CCControl-Examples

A quick example to show you how we use the CCSlider after integrating the CCControl here:

- (id)init
{
    if((self=[super init]))
    {
        CGSize screenSize = [[CCDirector sharedDirector] winSize];

        // Add a label in which the slider value will be display
        self.displayValueLabel = [CCLabelTTF labelWithString:@"Move the slider thumb!" fontName:@"Marker Felt" fontSize:32];
        displayValueLabel.anchorPoint = ccp(0.5f, -1);
        displayValueLabel.position = ccp(screenSize.width / 2.0f, screenSize.height / 2.0f);
        [self addChild:displayValueLabel];

        CCSlider *slider = [CCSlider sliderWithBackgroundFile:@"sliderBG.png" thumbFile:@"sliderThumb.png"];
        slider.anchorPoint = ccp(0.5f, 1);
        slider.position = ccp(screenSize.width / 2.0f, screenSize.height / 2.0f);

        // When the value of the slider will change, the given selector will be call
        [slider addTarget:self action:@selector(valueChanged:) forControlEvents:CCControlEventValueChanged];

        [self addChild:slider];
    }
    return self;
}

- (void)valueChanged:(CCSlider *)sender
{
    // Change value of label.
    displayValueLabel.string = [NSString stringWithFormat:@"Slider value = %.02f", sender.value];
}

Best,

I'm following a great tutorial by Todd Perkins.

The build succeeded, but the simulator doesn't show everything. The buttons for the menu doesn't show up.

I looked in the console and this is the error:

Terminating in response to SpringBoard's termination.

I tried to change the NSLog for "I'm in", I added a button called "button_s.png" but it's not
updating anything. I tried to close and reopen my project but the same error is showing up.

In GameButton.h, it's this:

#import "cocos2d.h"

@interface GameButton : CCSprite{

}

+(id)buttonWithText: (NSString *)buttonText isBig:(BOOL)big;
+(id)buttonWithText: (NSString *)buttonText;

-(id)initWithText:(NSString*) buttonText isBig:(BOOL)big;

@end

The code in GameButton.m

#import "GameButton.h"

@implementation GameButton

+(id)buttonWithText:(NSString *)buttonText isBig:(BOOL)big
{
	return[[[GameButton alloc]initWithText:buttonText isBig:big] autorelease];
}

+(id)buttonWithText:(NSString *)buttonText
{
	return [[[GameButton alloc]initWithText:buttonText isBig:NO] autorelease];
}

-(id)initWithText:(NSString *)buttonText isBig:(BOOL)big

{
	if((self== [super init]))
	   {
		   NSString *btnFrame = (big) ? @"button_b.png" : @"button_s.png";
		   int fSize = 12;
		   [self setDisplayFrame:[[CCSpriteFrameCache sharedSpriteFrameCache]
								  spriteFrameByName:btnFrame]];
		   CCLabelTTF *label =[CCLabelTTF labelWithString:buttonText fontName:@"Arial"
												 fontSize:fSize +big * fSize];
		   label.position = ccp(self.contentSize.width/2, self.contentSize.height/2);
		   [self addChild:label z:1];
		   CCLabelTTF *labelShadow = [CCLabelTTF labelWithString:buttonTextfontName:@"Arial" fontSize:fSize + big *fSize];
		   labelShadow.position = ccp(self.contentSize.width/2 - (2 + big *2),self.contentSize.height/2);
		   labelShadow.color = ccBLACK;
		   labelShadow.opacity = 150;
		   [self addChild:labelShadow];
		   NSLog(@"I'm in");
		}
	   return self;
}

@end

I already checked in the target folder if the button.s and button.b are there and they are.

I really don't know where to look now. You have an idea? Maybe it's the xcode version I have, 3.2.6?
The tutorial I'm following is version 4, does it make a big difference? I can't have version 4 because my mac is 10.6.8 snow leopard.

buttons and menu are on screen but nothing happen when buttons pushed:

'
CCMenuItemImage *menuB = [CCMenuItemImage itemFromNormalImage:@"menuB.png" selectedImage:@"menuB.png" target:self selector:@selector(goMenu:)];
CCMenuItemImage *tryAgainB = [CCMenuItemImage itemFromNormalImage:@"tryAgainB.png" selectedImage:@"tryAgainB.png" target:self selector:@selector(tryAgain:)];
CCMenuItemImage *menuGoodByeT = [CCMenuItemImage itemFromNormalImage:@"menu.png" selectedImage:@"menu.png" target:self selector:@selector(nothing:)];

menuB.position=ccp(-65,-40);
tryAgainB.position=ccp(15,-40);

menu = [CCMenu menuWithItems:menu,menuB,tryAgainB, nil];
menu.isTouchEnabled = YES;
[self addChild: menu];
'

yes, the method is having : id sender .
whats wrong with this menus ?? it some how always has problems.

When you go to send a SMS message in landscape mode, the bar containing the "Cancel" button is pushed up and off the screen and a black line is showing in its place. Not so good if people cant cancel!

Help!

Hi all! Can anybody explain me how i can get touch position in a button(CCMenuItemImage) in the selector method?

for example i have this snippet of code:

CCMenuItemImage *myMenuItem = [CCMenuItemImage itemFromNormalImage:imageNormal
							selectedImage:imageSelected
							disabledImage:imageDisable
								target:self
								selector:@selector(myMenuItemWasOn)];

	CCMenu *myMenu = [CCMenu menuWithItems:myMenuItem,nil];
	[self addChild:myMenu z:100];
	[myMenu setPosition:CGPointMake(200, 200)];

then after i have pressed the button method "myMenuItemWasOn" will be called:

- (void) myMenuItemWasOn
{
	CGPoint touchPos =  ?//how to get touch pos here?
}

Hey guys, I've been having problems with CCMenuItem and its timing with CCCallFunc.

Basically I'm getting 'EXC_BAD_ACCESS'

@ this line of the CCMenuItem class

-(void) ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event
{
    ...
    [selectedItem_ unselected]; // EXC_BAD_ACCESS
    [selectedItem_ activate];
    ...
}

It seems the menu item is deallocated before the touch ends. I'm using CCCallFunc to call a 'removeThisSprite' method that removes it from the parent

so the last action of the CCMenuItem sequence I call:

[CCCallFuncO actionWithTarget:self selector:@selector(removeThisSprite:) object: _currentButton]

The removeThisSprite method is like this:

CCMenuItemSprite2 *sender = nil;
sender.isEnabled = NO;

if ([_sender isKindOfClass:[CCMenuItemSprite class]]) {
    sender = _sender;
    [sender removeFromParentAndCleanup: YES];
}

This generally happens when the player 'spams' the screen with taps, but doesn't happen unless the taps are rapid. Which is likely to occur with a game I'm making.

Hello,
Here is one of the classes i wrote yesterday and i plan to use it trough out the menus in the future games. It is not yet fully tested, so it might have some bugs. Also it can be greatly improved upon.

- (void) PlayRelease

}

Say I have 2 buttons, and they both call highlightAmmo:
How would I check to see which button was pressed?

grapeDD = [CCMenuItemSprite
				 itemFromNormalSprite:[CCSprite spriteWithSpriteFrameName:@"grapeDD.png"]
				 selectedSprite:[CCSprite spriteWithSpriteFrameName:@"grapeDD.png"]
				 target:self
				 selector:@selector(highlightAmmo:)];

rockDD = [CCMenuItemSprite
				 itemFromNormalSprite:[CCSprite spriteWithSpriteFrameName:@"rockDD.png"]
				 selectedSprite:[CCSprite spriteWithSpriteFrameName:@"rockDD.png"]
				 target:self
				 selector:@selector(highlightAmmo:)];

- (void) highlightAmmo: (CCMenuItem  *) menuItem {
NSLog(@"Ammo highlighted");
}

how would i go about moving a b2body up and down with a button?

what type of body should it be ?(b2_dynamicBody, b2_kinematicBody), etc..)

How to repeat an action while MenuItem button is held down?
I tried to make a subclass on CCMenuItemImage and made

-(void) selected
{
	[super selected];
	buttonHeld = true;
}
-(void) unselected
{
	[super unselected];
	buttonHeld = false;
}

and put this on my init

CCMenuItem *upButtonItem = [CCMenuItemSpriteHoldable
                                itemFromNormalImage:@"up.png" selectedImage:@"upsel.png"
                                target:self selector:@selector(upButtonTapped:)];

but it did nothing... :(
it just loads the (void) upButtonTapped when I release the button.
is there any way to make a button that allows u to hold down?

Thank you

Hello everyone, i made a class called "csprite" (character sprite) it's the class of the main character of my game, who you move, but for move it i wanna put in the screen buttons (up,down,left,right) for those i use the MenuItem, 4 items with their respectives selector.

Each time you press the button the character moves 10 pixels, but, the problem is the character moves only once, and for move again you need press again the button.
How can i made, the character moves while you hold the button down??
I mean, if you press the button and hold it, the character moves until you release.

i need help with this code. not sure how to write a code to disable/enable the button based on a tag.
i tried to use "[levelMenu setIsEnabled:false];" but all the buttons are disabled.

//in my init method

        [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"texture.plist"];
        CCSpriteBatchNode *colorSprites = [CCSpriteBatchNode batchNodeWithFile:@"texture.png"];
	[self addChild:colorSprites];

        CCMenu *myMenu = [CCMenu menuWithItems:nil];

        int rows = 2;
        int cols = 4;
        static int padding=20;

        for(int count=0; count < (rows*cols); count++) {

        int index1 = count +1;
        NSString *spritefiles1 = [NSString stringWithFormat:@"sprite%d.png", index1];
        random1 = [CCSprite spriteWithSpriteFrameName:spritefiles1];

            CCMenuItemSprite *levelMenu = [CCMenuItemSprite itemFromNormalSprite:random1 selectedSprite:[CCSprite spriteWithFile:@"Iconselected.png"]   disabledSprite:[CCSprite spriteWithFile:@"Iconlocked.png"] target:self selector:@selector(levelSelected:)];

            int yOffset = padding+(int)(random1.contentSize.width/2-((random1.contentSize.width+padding)*(count/rows))); // or /cols to fill cols first
            int xOffset = padding+(int)(random1.contentSize.width/2+((random1.contentSize.width+padding)*(count%rows))); // or %cols to fill cols first
            levelMenu.position = ccp(xOffset, yOffset);

            levelMenu.tag = count+1;
            myMenu.position =ccp(0,300);
            [myMenu addChild:levelMenu];

            //testing to disable the button
           // [levelMenu setIsEnabled:false];

        }

-(void) levelSelected:(CCMenuItemSprite*) sender {
    int level = sender.tag;
    NSLog(@"test button number %d",level);
}

i have a jump action that plays when the jump button is pressed, the only problem is that every time the button is pressed he jumps even if it is in the middle of playing out the action, so i guess I'm asking for a way to make sure the entire action has completed before it is called to play again?

i am using sneakybuttons to make a jumpbutton and attackbutton,
i have done research and i still can't connect the buttons to the character..
this is what i have...

-(void) initButtons {
    CGSize screenSize = [CCDirector sharedDirector].winSize;
    CGRect jumpButtonDimensions =CGRectMake(0, 0, 64.0f, 64.0f);
    CGRect attackButtonDimensions =CGRectMake(0, 0, 64.0f, 64.0f);
    CGPoint jumpButtonPosition;
    CGPoint attackButtonPosition;

    jumpButtonPosition = ccp(screenSize.width*0.93f,screenSize.height*0.11f);
    attackButtonPosition = ccp(screenSize.width*0.93f,screenSize.height*0.35f);

    SneakyButtonSkinnedBase *jumpButtonBase = [[[SneakyButtonSkinnedBase alloc] init] autorelease];
    jumpButtonBase.position = jumpButtonPosition;
    jumpButtonBase.defaultSprite =[CCSprite spriteWithFile:@"JumphandUp.png"];
    jumpButtonBase.activatedSprite = [CCSprite spriteWithFile:@"JumphandDown.png"];
    jumpButtonBase.pressSprite =[CCSprite spriteWithFile:@"JumphandDown.png"];
    jumpButtonBase.button = [[SneakyButton alloc]initWithRect:jumpButtonDimensions];
    jumpButton = [jumpButtonBase.button retain];
    jumpButton.isToggleable = NO;
    [self addChild:jumpButtonBase];

    SneakyButtonSkinnedBase *attackButtonBase = [[[SneakyButtonSkinnedBase alloc] init] autorelease];
    attackButtonBase.position = attackButtonPosition;
    attackButtonBase.defaultSprite = [CCSprite spriteWithFile:@"attackhandUp.png"];
    attackButtonBase.activatedSprite = [CCSprite spriteWithFile:@"attackhandDown.png"];
    attackButtonBase.pressSprite = [CCSprite spriteWithFile:@"attackhandDown.png"];
    attackButtonBase.button = [[SneakyButton alloc]initWithRect:attackButtonDimensions];
    attackButton = [attackButtonBase.button retain];

Hi,
is there any way to generate random size buttons in cocos2d?

Hi all. I was wondering if anyone has an idea on the code to make a control scheme like SHIFT and SHIFT 2. Where the when you hold the left directional button the right button becomes a jump button and the same happens in reverse when you hold the right directional button to move in that direction the left button becomes a jump button. I'm working on a game with similar control concept.

I want to be able to swipe and change the sprite of a sneaky button. Can someone tell me how I can register a touch dispatcher without messing up the reading of the buttons, for it seems that when write return YES in the ccTouchesBegan the buttons will not be read properly. I really need help. Thanks in advance!!

I need help to create a sound on and off button in my game.

Explanation:

- When sound off/on is tapped, I want it to show sound off/on

- I have a different scene and I want that button to get rid of sound on both scenes.

Please reply

Hey guys this is my game that I have been working on for the last number of weeks. Hope you like it as much as I loved creating it..I loved the whole process (...besides the annoying memory issues that somehow evaded themselves from me for ages..Haha. - Though a huge huge thank you to Slembcke (Chipmunk) for not only the framework, but also the assistance that was given to me to sort out these memory problems.. and of course Riq also for the great framework)
:) :)

iTunes AppStore Description:

This immersive and addictive indie physics puzzler takes you into the delightful world of a button, some chalk and a load of strangely obstructive masking tape. Using your finger you must chalk up a guide for the button to travel along, ushering it to reach the goal of each level, though along the way be careful to gain enough momentum else failure will ensue. Marinate yourself in the user experience of Button and free your imagination to expand out far and wide, like peach coloured gum stretched between two school desks. As you play feel free to think of nice things like: water ripples, cheesecake, fresh plums, half frozen cordial, juicy watermelons, a sideways cap upon an old man's head, cellar doors, two otters arguing, aqua blue aura's or the smooth forehead of a fish - of course you could simply just play thoughtlessly instead.

Hello, i'm trying to create a Menu with image from sprite sheet, but i haven't find a way to do it, i did create a menu with images using
CCMenuItemImage *item = [CCMenuItemImage itemFromNormalImage:@"pausebutton.png" selectedImage:@"pausebutton.png" target:self selector:@selector(pause:)]; and adding it to a menu but when i use images from my sprite sheet this code doesn't work.

Hope someone can help me.

So I have a holdable SneakyButton called leftMoveButton and when the user holds the button the sprite moves and rins an animation. However, if the user does not hold the button, but he presses the button again and agin really fast, the sprite moves but does not do any animation. What I want is to move the sprite and do a quick animation on it when the user keeps pressing the button really fast. I want to leave as is for when the button is held. Here is my code:

if(leftMoveButton.active)
	{
		bear.flipX= NO;

		if(!actionIsRunning)
		{
			//this is a breathing action
			[bear stopAction:repeat2];
                        //this selector runs a CCRepeatForever action for animating the sprite.
                         // only works while holding the button
			[self performSelector:@selector(repeatAction)];
		}

 /*Need an if or something similar here to run the first animation.
I tried just running the first step by default but that would stop
the main animation from running and repeatedly
ran the first step even when holding the button.*/

                        //updates the position
			bear.position = CGPointMake(bear.position.x-100*0.02,bear.position.y);
                        //updates the layer position to be the bear position (pretty much)
			[self setCenterOfScreen:bear.position];

	}

Hi all,

I have 2 buttons that calls 2 animations, jump and push. Both are working but with a strange behavior. When I press push and then jump, my character only jumps without the animation. The second time I press the jump button it works as it should.

This is what I call when the button is pressed:

-(void)jump{
	yVel = 7;
	jumpDog = YES;
}

-(void)push{
	pushing = YES;
	yVel = 7;
}

And this is the selector that is scheduled:

-(void)check:(ccTime)delta{
	CCNode* dog = [self getChildByTag:GameSceneNodeTagDog];

	if (jumpDog || yVel != 7) {

                if (dog.position.y > 135) {
			yVel -= .30;
		}
		else  if(yVel != 7) {
			yVel = 0;
			...
			...
			//array to load the images and CCAnimation

                        [dog runAction:_jumpAction];
			jumpDog = NO;
		}
		dog.position = ccp(dog.position.x, dog.position.y + yVel);
	}

	if(pushing) {
			...
			...
			//array to load the images

                CCAnimation *pushAnim = [CCAnimation animationWithFrames:pushArray delay:0.05f];
		self.pushAction = [CCAnimate actionWithAnimation:pushAnim restoreOriginalFrame:NO];
                [dog runAction:_pushAction];
		pushing = NO;
	}
}

The yVel is the variable I change to make the character jump. But if I don't put it on the push method, the character wont do the push action.

I tried to schedule 2 different selectors but wont work either.

How to call two different CCAnimation from 2 buttons?

Just setting up a simple button using CCMenuItemImage like this to create and initialize it -

CCMenuItemImage* hudMenuItem = [CCMenuItemImage itemFromNormalImage:@"ButtonOne_1.png" selectedImage:@"ButtonOne_2.png" target:self selector:@selector(jumpButtonTouched:)];

But for some reason I am getting this error -

*** Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: '+[NSInvocation invocationWithMethodSignature:]: method signature argument cannot be nil'

EDIT:
This is the method being called when the button is pushed -

-(void)jumpButtonTouched {
	CCLOG(@"TAPPED");
}

hey I'm a beginner at this and i was wondering if i could get a step by step walkthrough on how to add animation with 20 frames then make that animation into a button that plays the animation when it is touched, and send me to a new scene when it is selected, then add that button into a menu.

and reset the animation if it is touched while it is already running?

(i have been at this for weeks with little progress, i have made my animation into a button
that plays the animation when it is touched, but i have a feeling that my coding is partially incorrect seeing that when i touch the button it moves to another position on the screen.)

here is my coding so far....

@synthesize playbutton = _playbutton;
@synthesize moveAction = _moveAction;
@synthesize walkAction = _walkAction;

+(CCScene *) scene
{
// 'scene' is an autorelease object.
CCScene *scene = [CCScene node];

// 'layer' is an autorelease object.
davie *layer = [davie node];

// add layer as a child to scene
[scene addChild: layer];

// return the scene
return scene;
}

-(id) init {
if((self = [super init])) {

[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"playbutton.plist"];

CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode batchNodeWithFile:@"playbutton.png"];
[self addChild:spriteSheet];

NSMutableArray *walkAnimFrames = [NSMutableArray array];
for(int i = 1; i <= 20; ++i) {
[walkAnimFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:@"play_button%02d.png", i]]];
}
CCAnimation *walkAnim = [CCAnimation animationWithFrames:walkAnimFrames delay:0.03f];

self.playbutton = [CCSprite spriteWithSpriteFrameName:@"play_button01.png"];
_playbutton.position = ccp(100,100);
self.walkAction = [CCRepeat actionWithAction:[CCAnimate actionWithAnimation:walkAnim restoreOriginalFrame:YES ] times:1];

self.isTouchEnabled = YES;

CCMenuItemSprite *dummyMenuItem1 =
[CCMenuItemSprite itemFromNormalSprite:_playbutton
selectedSprite: Nil
target: self
selector: @selector(dummyButton1Pressed)
];

CCMenu *menu = [CCMenu menuWithItems: dummyMenuItem1, nil];
menu.anchorPoint = ccp(0,0);
menu.position = ccp(100,100);
[self addChild: menu];
}
return self;
}
- (void) dummyButton1Pressed
{
[_playbutton runAction:_walkAction];

NSLog(@"dummy button 1 pressed");
}

@end

Hi, i just created grid menu from other code found on the internet. It's from three menus, menu image, menu font (text, number, 1,2,3,4,5...) and menu stars. there is a function, sorting menuitems to the grid. You can call it and set up like you want.
I hope it help someone.

SKDTutor and I have been working on something called GamePack for the last few weeks... It allows you to easily create things that you may need in your game without having to go through all the trouble, tweaking, and debugging... With GamePack everything is simplified, keeping your code nice and clean... You may have already seen GPJoystick, which is a success, but here soon we are going to be releasing many more GamePack classes... Here is a list of things that will be in GamePack(you may suggest things you want)

GPJoystick - released
GPButton - Almost Done
GPHoldButton - Almost Ready For Release(couple things to add)
GPSlider - Almost Ready For Release(couple things to add)
GPLoadingBar - In the works

GPJoyctick
-------------------------------
Easily create multiple joystick that are easy to use, manage, and support multitouch 100%!
http://www.youtube.com/watch?v=FzzHyPaCURY

GPButton
-------------------------------
Create buttons without having to use a CCMenu, simplifying your code... Plus even more features than a normal CCMenuItem

GPHoldButton
-------------------------------
A button that repeatedly runs a method whenever held down, great for thrust buttons!

GPSlider
-------------------------------
Creates a slider that returns a value in between the min and max values... It is great for volume sliders!

GPLoadingBar
-------------------------------
An easy to implement bar that can return loading progress, great for loading scenes!

If you have any thing you want in Game Pack just comment :)

Pricing:
GPJoystick - $5-7 ($5 comes with no updates)
GPButton - $2
GPHoldButton - $2
GPSlider - $3
GPLoadingBar - $5
GamePack Complete: $15 ( comes with all updates)

Hi,

I would like to know how can I make a Tap & Hold action in cocos2d-iPhone buttons?

Thanks!

Hey developers,

I am just searching everywhere how to change the default touch up inside state on the CCMenuItemImage to touchdown state ?

Thanks in advance,
Best regards

Hello everybody! It's been a while since you've heard the word on SneakyInput.

The word is: I'm kicking ass! :) I've received $105 in donations as of version 0.2. You might be wondering what all that money buys, the answer is: SneakyInput 0.3!

I'm planning the next version right now, here are the currently planned features:

Directional Analog Joysticks/Sliders - Joysticks that only work in two directions from the center in one line. This can be used with or without auto-center to make all sorts of controls, such as thruster, balance, or volume/fader controls.

Visual Input Diagnostics - Debugging tools, graphs that show data for the sneakyinput it's enabled for, bars for force, velocity indicators, rotation, angle, degrees, position, button state, slider position, etc. Also doubles as indicators for an interface, such as making a green light to show that something is enabled.

Event System/Callbacks - This one is a doozie, and I would appreciate a lot of user input.(pun intended) Basically you'll be able to set events for certain states, so like, a range of force in a certain direction, or the activation of a button. There will also be all the usual callbacks, such as input started/finished/is happening/etc.

Draggable Buttons - Pretty self explanatory

SneakyKnob/SneakySlider - A knob and a slider, with and without "clicks", and also toggleable auto-return and value-linking (moves to reflect change in value)

SneakyBlister - A controller that will generate SneakyButtons around an object, so that you are presented with options when you touch an object. Pretty handy stuff. I'm sure everybody will really appreciate/abuse this one ;)

Now, these are just the things I want to do. I'm pretty overambitious. We'll see how much of this really makes it into the next version. Do you have suggestions? Do you have something you really want? A good idea? Do you want to collaborate? Come to the GitHub! You can post your thoughts and ideas here as well, but the only way to make sure everybody working on the project will see what you said is to post them in Issues on the GitHub.

If you use SneakyInput, be sure to let us know, we really appreciate it! :)
