屏幕外视差节点滚动与清洁器

Question

管理滚动我的CCLayers视差节点，但我如何设置滚动的边界?

使用:

- (void)registerWithTouchDispatcher {
    [[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:1 swallowsTouches:NO];
}
-(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event {
    return YES;
}
-(void) ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event
{
    CGPoint touchLocation = [touch locationInView: [touch view]];   
    CGPoint prevLocation = [touch previousLocationInView: [touch view]];    
    touchLocation = [[CCDirector sharedDirector] convertToGL: touchLocation];
    prevLocation = [[CCDirector sharedDirector] convertToGL: prevLocation];
    CGPoint diff = ccpSub(touchLocation,prevLocation);
    CCNode *node = [self getChildByTag:kTagNode];
    CGPoint currentPos = [node position];
    [node setPosition: ccpAdd(currentPos, diff)];
}

你可以设置ZoomController的swallowsTouches属性，并查看TargetTouchDelegate来处理更复杂的触摸事件
