如何区分水龙头和水龙头

标签: objective-c ios cocos2d-iphone touch gesture-recognition

我正在创建一个应用程序并且我正在尝试制作它以便我可以在屏幕上拖动精灵(顶部有第二个精灵),但如果我只是点击精灵,则应调用其他一些方法。< / p>

当我触摸精灵的边缘时,我的拖动工作正常,但是当我尝试从精灵的中间拖动时(第二个精灵位于顶部),拖动根本不起作用,但是tap被叫。

我知道为什么不这样做,所以,两个精灵都有相互冲突,因为顶部的那个在触碰到它下面的第二个之前吞下了触摸。

如果我希望精灵在手指移动的情况下拖动,我怎么能实现这个呢?但是我想在只给出一个水龙头的情况下注册水龙头(IE手指没有在屏幕上移动)? / p>

我正在使用的精灵的视觉效果(如果它有帮助): enter image description here

黄色符文是与其下方石头分开的精灵(因为涉及动画)。

--------Touch for the top sprite----------
-(BOOL) ccTouchBegan:(UITouch*)touch withEvent:(UIEvent *)event{
    lastTouchLocation = [RuneScene locationFromTouch:touch];
    BOOL isTouchHandled = CGRectContainsPoint([charSprite boundingBox], lastTouchLocation);

    return isTouchHandled;
}
-(void) ccTouchEnded:(UITouch*)touch withEvent:(UIEvent *)event{
    NSLog(@"Tap received!");

}

------Touch for the bottom sprite--------

-(BOOL) ccTouchBegan:(UITouch*)touch withEvent:(UIEvent *)event{
    lastTouchLocation = [RuneScene locationFromTouch:touch];
    BOOL isTouchHandled = NO;

    // Check if this touch is on the Spider's sprite.
    if (CGRectContainsPoint([current.runeSprite boundingBox], lastTouchLocation)){
        mover = current;
        isTouchHandled = YES;
    }
    else if(CGRectContainsPoint([rune1.runeSprite boundingBox], lastTouchLocation)){
        mover = rune1;
        isTouchHandled = YES;
    }
    else if(CGRectContainsPoint([rune2.runeSprite boundingBox], lastTouchLocation)){
        mover = rune2;
        isTouchHandled = YES;
    }else if(CGRectContainsPoint([rune3.runeSprite boundingBox], lastTouchLocation)){
        mover = rune3;
        isTouchHandled = YES;
    }else if(CGRectContainsPoint([rune4.runeSprite boundingBox], lastTouchLocation)){
        mover = rune4;
        isTouchHandled = YES;
    }else if(CGRectContainsPoint([rune5.runeSprite boundingBox], lastTouchLocation)){
        mover = rune5;
        isTouchHandled = YES;
    }else if(CGRectContainsPoint([rune6.runeSprite boundingBox], lastTouchLocation)){
        mover = rune6;
        isTouchHandled = YES;
    }else if(CGRectContainsPoint([rune7.runeSprite boundingBox], lastTouchLocation)){
        mover = rune7;
        isTouchHandled = YES;
    }else if(CGRectContainsPoint([rune0.runeSprite boundingBox], lastTouchLocation)){
        mover = rune0;
        isTouchHandled = YES;
    }

    // Stop the move action so it doesn't interfere with the user's scrolling.
    //[self stopActionByTag:ActionTagCastingLayerMovesBack];

    // Always swallow touches, GameLayer is the last layer to receive touches.
    return isTouchHandled;

}

-(void) ccTouchMoved:(UITouch*)touch withEvent:(UIEvent *)event{
    CGPoint currentTouchLocation = [RuneScene locationFromTouch:touch]; 

    // Take the difference of the current to the last touch location.
    CGPoint moveTo = ccpSub(lastTouchLocation, currentTouchLocation);

    // Then reverse it since the goal is not to give the impression of moving the camera over the background, 
    // but to touch and move the background.
    moveTo = ccpMult(moveTo, -1);

    lastTouchLocation = currentTouchLocation;

    [self moveActionWithLocation: moveTo];
}

-(void) ccTouchEnded:(UITouch*)touch withEvent:(UIEvent *)event{
    if (!current.isPlaced && mover == current && currentR < Rune6) {
        // Move the game layer back to its designated position.
        CCMoveTo* move = [CCMoveTo actionWithDuration:1 position:curPt];
        CCEaseIn* ease = [CCEaseIn actionWithAction:move rate:0.5f];
        //ease.tag = ActionTagCastingLayerMovesBack;
        [current.runeSprite runAction:ease];

        [current setIsPlaced:YES];
        current.charSprite = [characters objectAtIndex:currentR];
        current.charSprite.position = curPt;
        //charSprite.visible = YES;
        [current performSelector:@selector(fade:) withObject:current.charSprite afterDelay:1];
        [current reorderChild:current.charSprite z:10];

        [self updateCurrentRune:currentR];
        [self updateCurrentCastNum:currentP];
        [self reorderChild:current z:10];
    }
}

我试着查看UITapGestureRecognizer,但我尝试实现的所有内容都无法运行。我的图层/精灵不会让我把它们添加为手势。我还在cocos2d论坛上阅读了有关CCGrstureRecognizer或其他内容的内容,但我找不到该课程的任何文档,也无法找到如何实际使用它...

有没有人知道如何帮助我处理我的问题?

而不是使用(如果CGRectContainsPoint)尝试使用view的pointInside:withEvent:返回NO。这将导致系统表现得像你的观点甚至不存在。
