My project in cocos2dv3 is throwing ARC Sematic Issue
Multiple methods named 'setRotation:' found with mismatched result, parameter type or attributes
while archiving(release mode). It runs fine while deploying to simulator/device (debug mode).
In release mode compiler gets confused between the implementation of rotation in UIRotationGestureRecognizer
and CCNode
.
When I got the error in CCBAnimationManager.m
, I typecasted the object calling the selector setRotation to (CCNode
*) but then the error crept up in CCActionInterval
. I'm hoping there is a better solution than typecasting everywhere in cocos2d library.
What am i doing wrong? Thankyou for your time.
EDIT
@interface CCAction : NSObject <NSCopying> {
id __unsafe_unretained _originalTarget;
id __unsafe_unretained _target;
NSInteger _tag;
}
@property (nonatomic,readonly,unsafe_unretained) id target;
@property (nonatomic,readonly,unsafe_unretained) id originalTarget;
@property (nonatomic,readwrite,assign) NSInteger tag;
in
CCAction.m
@synthesize tag = _tag, target = _target, originalTarget = _originalTarget;
-(void) startWithTarget:(id)aTarget
{
_originalTarget = _target = aTarget;
}
-(void) startWithTarget:(id)aTarget
{
_originalTarget = _target = aTarget;
}
Class Hierarchy
@interface CCActionFiniteTime : CCAction <NSCopying>
@interface CCActionInterval: CCActionFiniteTime <NSCopying>
@interface CCBRotateTo : CCActionInterval <NSCopying>
CCBRotateTo.m {
-(void) startWithTarget:(CCNode *)aTarget
{
[super startWithTarget:aTarget];
startAngle_ = [self.target rotation];
diffAngle_ = dstAngle_ - startAngle_;
}
-(void) update: (CCTime) t
{
[self.target setRotation: startAngle_ + diffAngle_ * t];
}
}
This problem gave me a big headache. Though I've upgraded cocos2d to v2.2 version for my old project (too complex to update to v3), I still got this warning. And any animation I created use rotation in the SpriteBuilder does act oddly, as I described here: Rotation animation issue on iPhone5S with cocos2d 2.0
Finally I used type casting to solve it as following in CCBAnimationManager.m
@implementation CCBRotateTo
-(void)startWithTarget:(CCNode *)aTarget
{
[super startWithTarget:aTarget];
starAngle_ = [(CCNode *)self.target rotation];
diffAngle_ = dstAngle_ - startAngle_;
}
-(void)update:(ccTime)t
{
[(CCNode *)self.target setRotation: startAngle_ + diffAngle_ * t];
}
With this change, now I can support arm64 too.
