c# - unity hold touch水平移动

Question

我不知道如何开始，我想在按住触摸时左右移动我的角色。

就像在这个游戏中:

Example Game - Stairs from Ketchapp

我只有检测屏幕左侧或右侧空间的脚本。

public float forwardSpeed = 5f;
public float sideSpeed = 5f;

private void Update()
{
    Vector3 deltaPosition = transform.forward * forwardSpeed;
    if (Input.touchCount > 0)
    {
        Vector3 touchPosition = Input.GetTouch(0).position;
        if (touchPosition.x > Screen.width * 0.5f)
            deltaPosition += transform.right * sideSpeed;
        else
            deltaPosition -= transform.right * sideSpeed;
    }
    transform.position += deltaPosition * Time.deltaTime;
}

Answer 1

这个解决方案适合我。它用于简单的方 block 破坏游戏，用于向左或向右移动 Racket 。

void Update () {
    if (Input.touchCount > 0){
        Touch touch = Input.GetTouch(0);

        int direction = (touch.position.x > (Screen.width / 2)) ? 1 : -1;
        MovePaddle(direction);
    }

}

void MovePaddle(int direction){
    float xPos = transform.position.x + (direction * Time.deltaTime * paddleSpeed);
    playerPos = new Vector3 (Mathf.Clamp (xPos, -8f, 8f), -9.5f, 0f);
    transform.position = playerPos;
}
