Try CCCallBlockN
which gives the block the node running the action as parameter. The current setup retains self
inside the block which may cause the node not to dealloc later on because the sequence runs forever and thus holds a strong self-reference until the node deallocates - I can't say if cocos2d is able to clean it up properly, it should but it might not.
Not sure if this is related to your issue or not but it seems to me a likely explanation considering everything else in the code snippet looks fine.
CCCallBlockN *zOrderBehind = [CCCallBlockN actionWithBlock:^(CCNode* node){
[node setZOrder:kManaSpriteBehindCrystalZValue];
}];
CCCallBlockN *zOrderInFront = [CCCallBlockN actionWithBlock:^(CCNode* node){
[node setZOrder:kManaSpriteZValue];
}];
If that doesn't work either then try CCActionTween
which allows changing any property by name.
id zOrderChange = [CCActionTween actionWithDuration:0.0
key:"zOrder"
from:kManaSpriteZValue
to:kManaSpriteZValue];
I'm not sure if from
/ to
having the same value will work. If it doesn't try using 0 as the from
parameter and perhaps even increasing duration
to some low value like 0.01.
