如果玩家处于尖刺状态，如何每秒秒后对其造成伤害? [英] How to Damage Player after each Second if he is on Spikes?

问题描述

我得到了尖刺和bool onSpikes，它告诉玩家是否为onSpikes. 当前，如果玩家启用了秒杀，则生命值会持续下降.

I got Spikes and the bool onSpikes, wich tells if the player is onSpikes or not. Currently the health goes Down constantly, if the player is onSpikes.

if(onSpikes)
    {
        health -= 0.01f;            
    }

但是我认为这不是一个好的解决方案，因为我处于无效的Update()中，并且我无论如何都希望Health丢弃更大的块(例如每秒-0.2f).

But I think this it isn't a good solution, cause I'm in void Update(), and I anyways wanted the Health to drop in bigger pieces ( like -0.2f each second).

我已经尝试构建方法并使用Invoke，但是像这样，我的播放器并没有失去任何健康. 代码:

I've already tried building an Method and use Invoke, but like this my player dind't lost health at all. Code:

    private void Update(){
        Debug.Log("Player on Spikes: "+SpikeDMG.onSpikes);
        bar.localScale = new Vector3(health,1f);

        if(SpikeDMG.onSpikes)
        {
            Invoke("doDmg",1);

        }


        //Wenn leben unter 0 fällt ==> starte szene neu
        if(health <=0){
             int scene = SceneManager.GetActiveScene().buildIndex;
            SceneManager.LoadScene(scene, LoadSceneMode.Single);
            Time.timeScale = 1;
            SpikeDMG.onSpikes = false;
        }
    }

    void doDmg(){
        health -= 10/100;
    }

}

推荐答案

要执行的下一个动作是使用某种时间戳.还此处进行了描述，并此处.

What you want to do is use some kind of time stamp, when your next action should be executed. It is also described here and here.

private float spikeDamageAt= 0.0f;

void update() {    
    if(onSpikes && Time.time >= spikeDamageAt) {
        health -= 0.01f;
        spikeDamageAt= Time.time + 1.0f; // for 1 seconds
    }
}
