[Unity]Update関数内で最初の一回だけ実行する

UnityのAwake()やStart()では書けず、Update関数内でシーンがロードされた後一回だけ実行する方法です。

bool isOnce = true;
void Update(){
    if(isOnce){
       //処理内容
       isOnce = false;
    }
}

bool型ではなく、int型を用いれば最初の3回だけ実行するといったことも可能です。

int Three = 0;
void Update(){
    if(Three < 3){
       //処理内容
       Three++;
    }
}
