如何在Unity下降阶梯时阻止玩家走开

Question

所以我希望我的球员能够在无意间跌落的情况下上下梯子。爬上很容易，让他们向前走到墙上，他们会碰撞并保持静止但是当他们使用“后退”按钮下降时，他们将开始非常短暂地下降，但立即走下梯子。暂时禁用播放器脚本是一个混乱的过程，所以我想知道什么是一个好的选择。

我正在使用transform在ladderScript中提升和降低我的玩家，并将其移至playerScript。

脚本（为简洁而修改）

public class LadderScript : MonoBehaviour {

    private playerScript pScript; //<--These both contain the colliding players script...
    private Collider collided; //<---- ...and collider when Update runs
    private bool triggerStay; //used to prevent Update from running while there is no contact

    void Start()
    {
        triggerStay = false;
    }

    ...

    void Update() //Runs once per collider that is touching the player every frame
    {
        if (triggerStay) {
            if (collided.CompareTag ("Player")) { //A player is touching the ladder
                /*  
                if (!pScript.getIsGrounded ()) {    //Ineffective
                    pScript.enabled = false;
                } else if (pScript.getIsGrounded ()) {
                    pScript.enabled = true;
                }
                    */
                if (Input.GetAxis ("Vertical") < 0) { // Player should go down
                    collided.transform.Translate (0, -.1f, 0);
                } else if (Input.GetAxis ("Vertical") > 0) //Player should go up
                        collided.transform.Translate (0, .1f, 0);
            }
        }
    }

     ...

}
