CCAnimate/CCAnimation cause inconsistent setTexture behavior in cocos2d on iPhone
- by chillid
Hi,
I have a character that goes through multiple states. The state changes are reflected by means of a sprite image (texture) change. The state change is triggered by a user tapping on the sprite. This works consistently and quite well.
I then added an animation during State0. Now, when the user taps - setTexture gets executed to change the texture to reflect State1, however some of the times (unpredictable) it does not change the texture.
The code flows as below:
// 1.
// Create the animation sequence
CGRect frame1Rect = CGRectMake(0,32,32,32);
CGRect frame2Rect = CGRectMake(32,32,32,32);
CCTexture2D* texWithAnimation = [[CCTextureCache sharedTextureCache]
addImage:@"Frames0_1_thinkNthickoutline32x32.png"];
id anim = [[[CCAnimation alloc] initWithName:@"Sports" delay:1/25.0] autorelease];
[anim addFrame:[CCSpriteFrame frameWithTexture:texWithAnimation rect:frame1Rect offset:ccp(0,0)]];
[anim addFrame:[CCSpriteFrame frameWithTexture:texWithAnimation rect:frame2Rect offset:ccp(0,0)]];
// Make the animation sequence repeat forever
id myAction = [CCAnimate actionWithAnimation: anim restoreOriginalFrame:NO];
// 2.
// Run the animation:
sports = [[CCRepeatForever alloc] init];
[sports initWithAction:myAction];
[self.sprite runAction:sports];
// 3. stop action on state change and change texture:
NSLog(@"Stopping action");
[sprite stopAction:sports];
NSLog(@"Changing texture for kCJSports");
[self setTexture: [[CCTextureCache sharedTextureCache] addImage:@"SportsOpen.png"]];
[self setTextureRect:CGRectMake(0,0,32,64)];
NSLog(@"Changed texture for kCJSports");
Note that all the NSLog lines get logged - and the texture RECT changes - but the image/texture changes only some of the times - fails for around 10-30% of times. Locking/threading/timing issue somewhere? My app (game) is single threaded and I only use the addImage and not the Async version. Any help much appreciated.
