I’m trying to test a Cocos2D app on an iPhone, and get this crash that I copied from the console:

Running it in the simulator runs fine, but I still get this message in the console when it starts up “CCSpriteFrameCache: Trying to use file ‘heroTestSheet.png’ as texture“
I suspect that’s where the problem starts. Maybe I’m just understanding how my code for my hero sprite subclass should be written. I thought heroTestSheet.png was the texture it was relying on to split up into other images referencing the plist.
Here’s my init in my hero subclass:
-(id) init{
self = [super init];
if (!self) {
return nil;
}
_collisWidthFromCtr = 16;
_collisHeightFromCtr = 16;
_collisPushPointsNums = 5;
_travelRectCenterPoints = [[NSMutableArray alloc] init];
_collisPushPoints = [[NSMutableArray alloc] init];
[_collisPushPoints insertObject:[NSValue valueWithCGPoint:CGPointMake( _collisWidthFromCtr, _collisHeightFromCtr)] atIndex:0];
[_collisPushPoints insertObject:[NSValue valueWithCGPoint:CGPointMake( _collisWidthFromCtr, 0)] atIndex:1];
[_collisPushPoints insertObject:[NSValue valueWithCGPoint:CGPointMake( _collisWidthFromCtr,-_collisHeightFromCtr)] atIndex:2];
[_collisPushPoints insertObject:[NSValue valueWithCGPoint:CGPointMake( 0, _collisHeightFromCtr)] atIndex:3];
[_collisPushPoints insertObject:[NSValue valueWithCGPoint:CGPointMake(-_collisWidthFromCtr, _collisHeightFromCtr)] atIndex:4];
_rectCheckRes = 32;
_speed = 8;
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"heroTestSheet.plist"];
_heroSpriteSheet = [CCSpriteBatchNode batchNodeWithFile:@"heroTestSheet.png"];
//[self addChild:_heroSpriteSheet];
NSMutableArray *heroSpriteFlyAnimFrames = [NSMutableArray array];
for(int i = 1; i <= 2; ++i) {
[heroSpriteFlyAnimFrames addObject:
[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:
[NSString stringWithFormat:@"heroFrame%d.png", i]]];
}
CCAnimation *heroSpriteFlyAnim = [CCAnimation animationWithFrames:heroSpriteFlyAnimFrames delay:0.03f];
_heroSprite = [CCSprite spriteWithSpriteFrameName:@"heroFrame1.png"];
_heroSpriteFlyAction = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:heroSpriteFlyAnim restoreOriginalFrame:NO]];
[_heroSprite runAction:_heroSpriteFlyAction];
[_heroSpriteSheet addChild:_heroSprite];
return self;
}
Please excuse me if I’m being unclear, so let me know any other info I need to provide. Just posting this for now because I don’t know where else to start to solve it and what other info I should provide, and it might be obvious to some other cocos devs whats wrong from what I posted. Thanks
Figured it out.. it was just the heroTestSheet.png it was trying to use was somehow invalid. I exported in an older photoshop, but I’m not really positive what settings it had. I exported it again from a newer photoshop without any color mange settings, and now it works fine!
