我几乎我的比赛做，但我不能让我的多点触摸的工作：严重的多点触控问题
我在的appdelegate
[glView setMultipleTouchEnabled:YES];
(also tried [window setMultiTouchEnabled:YES];)
得到了我Bomb.h
@interface Bomb : CCLayer (I also tried CCNode with <ccTargetTouchDelegate>)
Bomb.m
-(void)onEnter
{
[[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:kCCMenuTouchPriority swallowsTouches:YES];
[super onEnter];
}
-(void)onExit
{
[[CCTouchDispatcher sharedDispatcher] removeDelegate:self];
[super onExit];
}
(Also tried registerWithTouchDispatcher withouth onEnter and onExit and also tried with [super registerWithTouchDispatcher])
-(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
{
if(isPaused || !canBeDragged || LOST)
return NO;
//take the coordinates of the touch and transform them into the OpenGL system.
CGPoint location = [touch locationInView: [touch view]];
location = [[CCDirector sharedDirector] convertToGL: location];
CGRect frame = CGRectMake(self.position.x, self.position.y, self.contentSize.width, self.contentSize.height);
if(!CGRectContainsPoint(frame, location))
return NO;
location.x *= factor;
location.y *= factor;
if(BombShape)
{
offsetX = BombShape->body->p.x – location.x;
offsetY = BombShape->body->p.y – location.y;
BombShape->body->v = cpvzero;
BombShape->collision_type++; //make it ‘Dragged’. For example RedNinja++ is DraggedRedNinja
}
return YES;
}

if(BombBody)
{
//during the dragging, the bomb must not have velocity. Otherwise, it will “run” beneath your finger.
//so we are constantly calculating the velocity and ,when you end the draging, assign that value to the velocity of the bomb.
velocity = cpv((location.x – prevLocation.x) * 30 , (location.y – prevLocation.y)*30);
CGPoint newPosition = cpv(location.x + offsetX, location.y + offsetY);
//test per X
canMoveOnX = CheckOnX(BombBody->p , newPosition,radius);
canMoveOnY = CheckOnY(BombBody->p , newPosition,radius);
if(canMoveOnX)
BombBody->p.x = newPosition.x;
if(canMoveOnY)
BombBody->p.y = newPosition.y;
}
}
//****************************************************************************************

return;
//set velocity back
BombShape->body->v = velocity;
BombShape->collision_type–;
offsetX = 0;
offsetY = 0;
}
//****************************************************************************************
-(void) ccTouchCancelled:(UITouch *)touch withEvent:(UIEvent *)event
{
}
不知何故，我似乎无法检测到我的第二个触摸：S。
我正在加载我的Bomb.h在一个没有触及CCLayer的GameScene中。
请帮忙。谢谢。
