ios - 使用 cclayers 滚动屏幕外视差节点

Question

使用视差节点滚动我的 CCLayers 但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)];

}

您可以设置 ZoomController 的 SwallowsTouches 属性并查看 TargetTouchDelegate 以处理更复杂的触摸事件。
