In my game, in beginning person is walking then after some time he is falling down. So i have made two seperate actions walkAction and fallAction. but when i call walkperson or fallperson seperately,it's working fine..but when i call walkperson then after sometime if i call fallperson then it won't run and application crashes without error log..and yeah if i stop action then it also gives me error.. Below is code : CCSprite *boy = [CCSprite spriteWithFile:@"wineBoyBody.png"]; boy.position = ccp(250,170); id walkAction = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:walkAnim restoreOriginalFrame:NO]]; id fallAction = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:fallAnim restoreOriginalFrame:NO]]; [boy runAction:walkAction]; Then using scheduler , I call [boy runAction:fallAction]; Now , wht i have to do ?

I am sorry if this question has already been addressed, but I have not seen the answer anywhere. Question: I know that the iPhone 4 can take lower res graphics and display them correctly automatically. I would like to create high res graphics for the iPhone 4, but by making higher res graphics the older iPhones will have a problem displaying the graphics, right? Will I have to create 2 sets of graphics for my games for now on? Thank you!

It is something similar to geometry wars or light wars (if you want a specific iPhone title). So you move the ship in space with one Joystick (I am using the Joystick class that comes with cocos). Now the problem is how to actualy translate the data provided by the Joystick into a sprite movement. I managed to do something with rotation: <pre><code>-(BOOL)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { if ([gamepad touchesMoved:touches withEvent:event] == YES) { CGPoint point = [gamepad getCurrentDegreeVelocity]; NSLog(@"x = %f Y = %f",point.x, point.y); id rotate = [CCRotateTo actionWithDuration:(10/point.y) angle:point.x]; [(CCSprite *)[self getChildByTag:0] runAction:rotate]; } return YES; }</code></pre> I think that it is something like what I want (I can't test it on the actual device because I can't install it onto a device with iPhone OS 3.0 - I am using iPhone SDK 4). But now I am having trouble actualy moving the sprite in the direction of the rotation. nirmal on "Call same sequence of actions on multiple sprite" http://www.cocos2d-iphone.org/forum/topic/8143#post-47408 Fri, 23 Jul 2010 06:32:54 +0000 nirmal 47408@http://www.cocos2d-iphone.org/forum/ Hi, I'm having problem in calling same sequence of actions on multiple sprite.

When the sprites are created I rotate them -150 degrees so they are pointing in the right direction but when I put them near each other, it appears that they are checking for collision as if they were still in the starting position. I am wondering how to fix this so their rects rotate to the same position. I tried: CGRectApplyAffineTransform(rect2, CGAffineTransformMakeRotation(-150.0f)); but it still isnt lined up right. Any ideas on how to fix this?

I'm using cocos 0.99.4 I have a simple setup. A CCLayer-subclass, in it's init-method I initialize a CCSpriteSheet and add it as child to the layer. ` <pre><code>- (id)init { ... enemySprites = [CCSpriteSheet spriteSheetWithFile:@"rock1.png"]; enemies = [[NSMutableDictionary alloc] init]; [self addChild:enemySprites z:3]; ...</code></pre> Now I am trying to add a new sprite to this sheet from my ControllerClass: <pre><code>NSArray *allEnemies = [[GameController sharedGameController] enemies]; CCSpriteSheet *enemiesSpriteSheet = baseViewLayer.enemySprites; NSMutableDictionary *layerEnemies = baseViewLayer.enemies; for (Enemy *enemy in allEnemies) { CCSprite *enemySprite = [layerEnemies objectForKey:[NSNumber numberWithInt:enemy.ID]]; if (CGRectContainsPoint(viewPort, enemy.position)) { if (enemySprite == nil) { enemySprite = [CCSprite spriteWithSpriteSheet:enemiesSpriteSheet rect:CGRectMake(0, 0, 64, 32)]; [enemiesSpriteSheet addChild:enemySprite z:3]; [layerEnemies setObject:enemySprite forKey:[NSNumber numberWithInt:enemy.ID]]; } enemySprite.position = [self viewPortCoordinatesWithPoint:enemy.position]; enemySprite.rotation = enemy.rotation; } else { if (enemySprite != nil) { [enemiesSpriteSheet removeChild:enemySprite cleanup:YES]; [layerEnemies removeObjectForKey:[NSNumber numberWithInt:enemy.ID]]; } } }</code></pre> The enemiesSpriteSheet is the sheet from the Layer. The dictionairy is to connect the modelobject to the sprites. But for some reason, the sprite does not show when i start the app. Other sprites added directly in the layers init method are shown properly. Does anyone see why? Drives me crazy! :) thanks alot ps: if i use the same part of code directly in the layer's init-method it works... calsmith on "Touch event on rotating sprite" http://www.cocos2d-iphone.org/forum/topic/8035#post-46798 Mon, 19 Jul 2010 12:16:47 +0000 calsmith 46798@http://www.cocos2d-iphone.org/forum/ Hi, I have tried every possible method of sprite touch detection I can find and none of them seem to work with sprites that have rotated my code: <pre><code>//add circle sprite hit zone (this is what I need touch detection for) circleHitZone = [CCSprite spriteWithFile:@"circle_10_hitzone.png"]; circleHitZone.anchorPoint = ccp(0,-0.9);//this is probs messing it up circleHitZone.position = ccp(winSize.width /2 , winSize.height/2); circleHitZone.color = ccc3(150,10,5); [self addChild:circleHitZone]; //start rotations id rotHit = [CCRotateBy actionWithDuration:20 angle:360]; id infinRotateHit = [CCRepeatForever actionWithAction: [CCSequence actions: rotHit, nil]]; [circleHitZone runAction:infinRotateHit];</code></pre> I'm trying to detect when 'circleHitZone' is tapped but all methods either don't work at all or work when I tap the anchor point I have tried creating a sprite that follows the circleHitZone but it just goes to the anchor point as well :( If anyone has any ideas please help me out, anything is appreciated Thanks.

Someone suggested using a RenderTexture, so that's what I've been trying. All I'm wanting to do is move an orb image on a 100x100 RenderTexture so I can see it moving "off" the RenderTexture region. I'm placing the RenderTexture over the game layer. The problem is I can't find a way to reset the RenderTexture, so whenever I move the orb image it doesn't clear it first and I'm left with a "shadow" of the previous image drawn. Here's the setup: orb = [Sprite spriteWithFile:@"blueOrb.png"]; [orb setPosition:ccp(50,50)]; [orb retain]; test = [RenderTexture renderTextureWithWidth:100.0 height:100.0]; [test setPosition:ccp(160,240)]; [self addChild:test z:1]; Here's what I'm calling in my step function: [orb setPosition:ccp(50.0,50.0+y)]; [test begin]; [orb visit]; [test end]; y+=1; Any help or guidance would be much appreciated! oscarmk on "Scaling sprites, reversing the scale and getting current content size" http://www.cocos2d-iphone.org/forum/topic/3840#post-23004 Mon, 11 Jan 2010 23:51:13 +0000 oscarmk 23004@http://www.cocos2d-iphone.org/forum/ Hello, I have a Sprite that I am constantly repositioning, and I would like to adjust the scale of the Sprite every time it is repositioned, first I tried ScaleBy, followed by reverse by and then again a new Scale By (so that I can scale based on original form), however is this the "right" way to do this?.

Moreover, I have read that some artifacts can happen. For example, we have tile size 32x32. I have read that graphics picture must be adjusted, so that actuall size will be 34x34 and this one pixel from each side is added to prevent artifacts in game. 1. How to prepare graphics for tmx map. Is there some easy solution? For example I have graphics in texture 1024x1024. Is there some way to automatically fix it? 2. Do I have to manually edit each tile in png graphics and add this 1 pixel (so that I copy neighbouring pixels) or there is some automatic way to do it easily. If all has to be done manualy, it is painful process. 3. This above questions were for game background. What about with sprites that are not part of tmx map graphcis? Are they also need to be fixed same way? As far as I understand, this is very painfull process in preparing graphics for the game. Could you give some guidance in this and enlight the way how to do it?

I want to do this so that I don't have to use time later in the game to load all the sprites and other objects.

Is it possible to adjust time in miliseconds (timing) between frames? For example, I want to set time between change to next frame (switching to next frame) to lets say 0,05 sec. Is this possible? This way I can adjust speed of animation.

I mean, move image around inside a polygon, if part of the image is outside of polygon border, that part becomes invisible, however still keep the part of image which is inside the polygon visible.
