Question

你好我试图制造一个枪系统，一切正常，除了存储在我的GameObject阵列playerGuns中的切换枪，它总是将它存储在0 当我按下另一个键时，它会禁用所有创建的对象。

我想这样做，当你按下键盘上的1-4键时它会切换在存储在playerGuns上的枪和禁用另一把枪的枪之间，你持有。

我无法找到问题发生的原因所以请帮忙。

我写了一个小脚本，应该处理你的四支枪的激活和停用。

希望它有所帮助，

Alex

public GameObject[] Guns;

void Start(){
    for (int i=0; i<3; i++){
        if(Guns[i] == null) Debug.LogError("Gun n°" + i +" is null);        
    }
}

void Update(){
    if(Input.GetKeyDown(Input.KeyCode.Alpha1)){
        setGunActive(1);
    }

    if(Input.GetKeyDown(Input.KeyCode.Alpha2)){
        setGunActive(2);
    }

    if(Input.GetKeyDown(Input.KeyCode.Alpha3)){
        setGunActive(3);
    }

    if(Input.GetKeyDown(Input.KeyCode.Alpha4)){
        setGunActive(4);
    }
}

void setGunActive(int n){
    foreach(GameObject g in Guns){
        g.setActive(false);
    }
    Guns[n].setActive(true);
}

在枪之间切换
