Question

我做了两个按钮（leftBtn和rightBtn）。按下和按下它们时工作正常..但是，当你按住时，然后将手指从按钮上移开并按下，按钮保持按下状态？

以下是touchDown和touchUp的代码

func touchDown(atPoint pos : CGPoint) {
    let rightBtn = childNode(withName: "rightBtn");
    let leftBtn = childNode(withName: "leftBtn");

    if(rightBtn?.frame.contains(pos) == true){
        right = true;
    }
    else if(leftBtn?.frame.contains(pos) == true){
        left = true;
    }
}

func touchMoved(toPoint pos : CGPoint) {

}

func touchUp(atPoint pos : CGPoint) {
    let rightBtn = childNode(withName: "rightBtn");
    let leftBtn = childNode(withName: "leftBtn");

    if(rightBtn?.frame.contains(pos) == true){
        right = false;
        carController.stopMove();
    }
    else if(leftBtn?.frame.contains(pos) == true){
        left = false;
        carController.stopMove();
    }
}

按钮保持向下，因为按钮不再出现（即手指向上移动并离开屏幕）。相反，它发生在视图的其他部分。如果您希望按钮不被按下，请考虑将代码添加到touchesMoved方法中。

SpriteKit按钮保持按下状态
