SKSpriteNode没有更新

Question

我只是希望spritenode在点击时移动。但看起来场景不会更新，直到第二次点击另一个spritenode点击。

我的错误在哪里？

Matrix4 m4 = new Matrix4();
Debug.Log(m4[1, 1]);

This is how I do what you are trying to do.

I think you should try the nodes(at: ) instead.

here is an example of it in use

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {


if let touch = touches.first {
//gets location
            let location = touch.location(in: self)
//gets of what nodes are at the location
            let object = nodes(at: location)
// if the there is a node on that location that is the sprite I want
            if object.contains(yourSprite){
//you can put what ever numbers you want to run in there. This simply
// determines the direction of the movement based on a t-Graph
                yourSprite.run(SKAction.moveBy(x: 0, y: -5, duration: 1))
            }
}
