Hi, i've just tried out the HKTMXTiledMap Cocos2D v2.1 code on Cocos2D v2.0 (needed a few minor fixes to get it working) with a tmx file containing tiles with dimensions of 64 x 64 pixels and with my project running in retina mode.

The code is compiling successfully but when I run the app the tiles appear to be twice as large as they should be and also some have dark lines seperating them. Does anyone have any ideas why this happens and a solution for this issue?

My tileset is 1280 x 1280 - would this cause a problem as I know square textures with sizes as powers of 2 are recommended?

Also cc_vertexz doesn't seem to be working and I cannot see my player sprite.

Please help someone as I was really hoping this extension would work for me!!

Thanks

Thanks Skyhawk, does cc_vertexz also work correctly and allow sprite interleaving between tiles? cheers :)

tileAt is included in the "experimental features" code file (doing essentially what you described).

Hi, this extension sounds awesome and also much needed for the retina implementation of my project. I have a few questions though: firstly does anyone know whether HKTMXTiledMap supports the cc_vertexz property for othogonal maps? This is essential for my project so hope so! Also I have heard that there is no tileAt: method, is this the case, and if so has anyone implemented a workaround eg getting a reference to the tileset texture then using the tile gid to calculate a rect to copy into a ccsprite? Thanks :)

Nevermind... I read back through the thread and found this post which describes how to set HKTMX_LAYER_SCALE_LIMIT to fix my scaling problem.

RTFM, indeed.

@skyhawk I would like to use HKTMXTiledMap in conjunction with CCPanZoomController. When I zoom out, I only see the tiles that HKTMXTiledMap draws (versus all of the tiles, as CCTMXTiledMap would show). I'd like to preserve the optimization when at zoom level 1 (running HKTMXTiledMap). Is there a way to tell my HKTMXTiledMap to draw more tiles than those displayed by default? I'd like to tell it to draw more if the user zooms out.

Hi Skyhawk,

I have been using HKTMXTiledMap for my iOS platform game. I am using Box2D to control the player movement and the layer scrolling. With cocos2d 1.1 version, it works perfectly fine. When I recently ported to cocos2d 2.0, I get black bars in my map. I am suspecting it is the way OpenGLES 2.0 deals with floating points, I am not 100% sure. If I round off the layer position, the black bars disappear, but the smoothness of scrolling is affected very badly.

I have uploaded two separate XCode projects to demonstrate the problem:
Cocos2d 1.1 based version (Works fine):
https://dl.dropboxusercontent.com/u/10673160/hktmxmap-test/LargeMapTest_cocos2dv11.zip

Cocos2d 2.1 based version (Black bars issue):
https://dl.dropboxusercontent.com/u/10673160/hktmxmap-test/LargeMapTest_cocos2dv21.zip

Please note that I have picked up HKTMXTiledMap from these links. Just made a one-line fix for Retina display (contentSizeInPixels to contentSize in 2.1 version of HKTMXLayer.m)
http://hkasoftware.com/fileserve/HKTMXTiledMap/cocos2d2.1/HKTMXTiledMap.zip
http://hkasoftware.com/fileserve/HKTMXTiledMap/cocos2d1.1/HKTMXTiledMap.zip

Can you please help me in fixing the black bars with the same level of smoothness as that of 1.1 version ?

Thank you!
The new version works great!
(It works with kobold 2d to)

The issue is that GL_ES_VERSION_2_0 is not defined on the mac. weird. removing the #else blocks and making the #if GL_ES_VERSION_2_0 code the default fixes the issue, but how come GL_ES_VERSION_2_0 not defined on mac?

Uploaded a new version which should work in your project.

Now I have uninstalled kobold and are using just cocos 2d with a fresh installation of xcode. The same problem still exist - white screen.
I have uploaded a project at:
https://docs.google.com/file/d/0B8PYKLDXW9xcZWIzNGRWU29CNHc/edit?usp=sharing

Is there a working Mac project somewhere I could take look at?

Fixed the layer opacity / colorization issues in the 2.1 version. Download the latest version from http://hkasoftware.com/fileserve/HKTMXTiledMap/cocos2d2.1/HKTMXTiledMap.zip

STEFFEN, YOU CAN UPDATE YOUR CHART NOW! I KNOW YOU'RE STALKING ME!

If you insist on using kobold2d, I suggest you look at kobold touch: http://www.koboldtouch.com/display/KTD/About+KoboldTouch#AboutKoboldTouch-KoboldTouchTilemapFeatures

He claims his tilemap is on par (speed wise) with mine and is rapidly implementing all the features I currently have.

That being said, I use HKTMXTiledMap in my mac cocos2d app extensively and it works fantastically.

Without a project or a test case, I can't really debug your particular scenario for you =)

Hi everyone. I'm using Kobold 2D with HKTMXTiledMap on my Mac, but I can't get HKTMXTiledMap to work.
My sourcecode looks like this:

#import "HelloWorldLayer.h"
#import "HKTMXTiledMap.h"

@interface HelloWorldLayer (PrivateMethods)
@end

@implementation HelloWorldLayer

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

HKTMXTiledMap *map = [HKTMXTiledMap tiledMapWithTMXFile:@"lawn2.tmx"];
[self addChild:map];
}

return self;
}

@end

If I run it in the iPhone or iPad simulator, everything works fine, so i guess the setup kobold 2d + HKTMXTiledMap is Ok. But when i run it for mac all I get is a white screen and the message: tilemap-Mac[10394:303] -[HKTMXLayer setPositionInPixels:]: unrecognized selector sent to instance 0x1020262a0
I can't find any solution to this... Can anyone please help me with it?

really just need to copy and paste this to every page or something (so people use the right version):

Apart from not being able to change layer opacity, I noticed some of the mirrored/flipped tiles were not showing properly. I am using Tiled 0.9, cocos2d 2.1 and this version of HKTMXTiledMap: https://github.com/cocos2d/cocos2d-iphone-extensions/tree/develop-v2/Extensions/HKTMXTiledMap

To fix the issue (that persisted after I applied one of the fixes in this thread), I copied the code from CCTMXLayer to HKTMXLayer on the flipping/mirroring section, like so:

if (tile & kFlippedDiagonallyFlag)
{
    uint32_t flag = tile & (kFlippedHorizontallyFlag | kFlippedVerticallyFlag );

    // handle the 4 diagonally flipped states.
    if (flag == kFlippedHorizontallyFlag)
    {
        texbase[0] = right;
        texbase[1] = top;
        texbase[2] = right;
        texbase[3] = bottom;
        texbase[4] = left;
        texbase[5] = top;
        texbase[6] = left;
        texbase[7] = bottom;
    }
    else if (flag == kFlippedVerticallyFlag)
    {
        texbase[0] = left;
        texbase[1] = bottom;
        texbase[2] = left;
        texbase[3] = top;
        texbase[4] = right;
        texbase[5] = bottom;
        texbase[6] = right;
        texbase[7] = top;
    }
    else if (flag == (kFlippedVerticallyFlag | kFlippedHorizontallyFlag) )
    {
        CC_SWAP(left,right);
        texbase[0] = right;
        texbase[1] = top;
        texbase[2] = right;
        texbase[3] = bottom;
        texbase[4] = left;
        texbase[5] = top;
        texbase[6] = left;
        texbase[7] = bottom;
    }
    else
    {
        CC_SWAP(left,right);
        texbase[0] = left;
        texbase[1] = bottom;
        texbase[2] = left;
        texbase[3] = top;
        texbase[4] = right;
        texbase[5] = bottom;
        texbase[6] = right;
        texbase[7] = top;
    }
}
else
{
    if (tile & kFlippedHorizontallyFlag)
        CC_SWAP(left,right);

    if (tile & kFlippedVerticallyFlag)
        CC_SWAP(top,bottom);

    texbase[0] = left;
    texbase[1] = top;
    texbase[2] = right;
    texbase[3] = top;
    texbase[4] = left;
    texbase[5] = bottom;
    texbase[6] = right;
    texbase[7] = bottom;
}

sorry, I messed projects up... this one is using cocos2d 2.1 and I can't get the opacity changes to work.

layer.opacity = 150;

Any ideas on how to make opacity changes possible on HKTMXLayer on cocos2d 2.0?

Yep - proper fix as to why it crashes would be best =)

I guess we watch that other thread you revived and see if a solution is found.

hmmm, maybe. But ideally it would be best if riq figured out what was going on =)
I've linked him to https://github.com/richardgroves/HKTMXTiledMap-crash.git in thread http://www.cocos2d-iphone.org/forum/topic/70268 to allow him to debug.

worst case scenario, people just flock to this thread, see the solution (hopefully) and go on.

@skyhawk: Thanks that fixes it. Looks like @greyhoundgames was having the same problem above.

Is there any way for the code to assert that #define is the correct value - either at compile time if it should always be 0, or run time if the tilemap is too big to handle using the vertex array objects (I'm assuming it's an OpenGL memory/resource problem and too many vertex array objects are being created by a large tilemap?)

in your ccConfig.h
set

#define CC_TEXTURE_ATLAS_USE_VAO 0

Project demonstrating the crash I see:

https://github.com/richardgroves/HKTMXTiledMap-crash.git

Examine HellowWorldLayer.m

Code at line 68 causes the crash (adding a HKTMXTiledMap from a menu item click), the same code run during init flow (line 87 of that file) doesn't crash.

Tilemap has had project confidential information wiped so it looks a bit odd, but demonstrates the problem.

Thanks,
Richard

provide a project please or tmx map for us to look at.

I'm having a problem with the latest HKTMXTiledMap from either https://github.com/cocos2d/cocos2d-iphone-extensions/tree/develop-v2 or http://hkasoftware.com/fileserve/HKTMXTiledMap/cocos2d2.1/HKTMXTiledMap.zip with cocos-2.1-rc0a

Basically if I have the director showStats:YES on it crashes as soon as the tilemap is rendered with the same crash location as @ffede81 reports above, but the call stack has it as being called from [CCDirector showStats] for the crash.

With showStats:NO it runs fine. tileMap is 200x200, just one layer being shown with one object layer containing one object.

i had to remove the Support/

@rakkarage, your version: does it use #import "Support/CGPointExtension.h" or #import "CGPointExtension.h"
(seems like it's entirely dependent on the users search paths)

@skyhawk:

if possible, could you send me a pull request with your latest changes ?
I placed it here:
https://github.com/cocos2d/cocos2d-iphone-extensions/tree/develop-v2

thanks.

Thanks for the updated link!

The fact is that I keep getting this error with the new version in HKTMXTiledMap line 87:

@interface HKTMXLayer : CCNodeRGBA <CCBlendProtocol>

Cannot find interface declaration for 'CCNodeRGBA', superclass of 'HKTMXLayer'

In order to fix it I can simply replace CCNodeRGBA with CCNode (is it safe enough?)

Another issue is for CGPointExtension import which should be fixed from:

#import "Support/CGPointExtension.h"

to

#import "CGPointExtension.h"

And in HKTMXTiledMap at line 178 need to change:

_children to children_ (this has probably already been fixed in 2.1rc0, while I'm using beta4)

After these changes I get the following EXC_BAD_ACCESS error in CCTextureAtlas class, line 519:

#if CC_TEXTURE_ATLAS_USE_TRIANGLE_STRIP
glDrawElements(GL_TRIANGLE_STRIP, (GLsizei) n*6, GL_UNSIGNED_SHORT, (GLvoid*) (start*6*sizeof(indices_[0])) );
#else
glDrawElements(GL_TRIANGLES, (GLsizei) n*6, GL_UNSIGNED_SHORT, (GLvoid*) (start*6*sizeof(indices_[0])) );
#endif

I think it's caused by the CCNodeRGBA class which is actually missing and that I replaced with CCNode. Could that be?

Anyway, in the game I'm developing I'm massively using the CCSprite tiles behavior. I know that there's an experimental class included in your project that could help me in this way, but I will probably keep using the standard CCTMXTiledMap class for now and live with some manual work, I'm used to it, no problem :)

@ffede81 your problem is you didn't apply the fix here: http://www.cocos2d-iphone.org/forum/topic/17945/page/8#post-196033 if you're running in retina mode.
