I'm trying to make a method that prevents player from spamming Space key.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerControllerX : MonoBehaviour
{
    public GameObject dogPrefab;
    private float setTime = 2.0f;
    private float timer = Time.time;

    // Update is called once per frame
    void Update()
    {
        timer  = Time.deltaTime;
        if (timer >= setTime)
        {
            SpawnDog();
        }
    }
    void SpawnDog()
    {
        // On spacebar press, send dog
        if (Input.GetKeyDown(KeyCode.Space))
        {
            Instantiate(dogPrefab, transform.position, dogPrefab.transform.rotation);
            timer = 0;
        }
    }

}

And this is an error statement from Unity: I think it was not a logic error

UnityException: get_time is not allowed to be called from a MonoBehaviour constructor (or instance field initializer), call it in Awake or Start instead. Called from MonoBehaviour 'PlayerControllerX' on game object 'Player'.

CodePudding user response：

Like say there you cannot set private float timer = Time.time; on the declaration. You should do something like this

private float timer = 0;

void Start(){
timer = Time.time;
}
