在Unity C＃中启动，暂停和重新启动计时器 - 仅在触发器内减少计时器并在外部触发器时重置

Question

This is what I need it to do.

Make a timer only decrease while staying in the trigger and reset when outside the trigger.

When timer1 = 0, pause the countdown timer and set teleport to 0

When timer1 = 1, Set the timer to 8 seconds and start counting down, IF timercountdown = 0, set teleport to 1 and set Timer1 to 0. (TO reset the timer)

This isnt working properly and Im really not sure why.

The timer gets locked at 8 and doesnt start decreasing when the Timer1 value equals 1.

Thank you

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

public class ProximityTeleport : MonoBehaviour {
    public float time;
    public int timer1 = 0;
    public int teleport = 0;
    public float timecountdown;   

    void Start () {
    }
    void Update () {

    if (timer1 == 0);
    {
        teleport = 0;
    }

    if (timer1 == 1);
    {
        timecountdown -= Time.deltaTime;

        if (timecountdown <= 0.0f);
        {
            teleport = 1;
            timer1 = 0;
        }

    }
}
    void OnTriggerEnter() {
        timecountdown = 8f;
        timer1 = 1;
    }

    void OnTriggerExit() {
        timer1 = 0; 
    }
}

I think it's some kind of logically problem. You say:

When timer1 = 0, pause the countdown timer and set teleport to 0

but you do:

    if (timer1 == 0);
    {
        timecountdown += Time.deltaTime;
        teleport = 0;
    }

And there is another problem: as long as timer1 = 1 you always set timecountdown = 8f; here:

    if (timer1 == 1);
    {
        timecountdown = 8f;
        timecountdown -= Time.deltaTime;

        if (timecountdown <= 0);
        {
            teleport = 1;
            timer1 = 0;
        }

    }

Hope this helps!

Edit: according to your comments I think I know what you want to do: You only want to decrease while staying in the trigger?

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

public class ProximityTeleport : MonoBehaviour {
    public float time;
    public int timer1 = 0;
    public int teleport = 0;
    public float timecountdown;   

    void Start () {
        timecountdown = 8f;
    }
    void Update () {

        if (timer1 == 0);
        {
            teleport = 0;
        }

        if (timer1 == 1);
        {
            timecountdown -= Time.deltaTime;

            if (timecountdown <= 0.0f);
            {
                teleport = 1;
                timer1 = 0;
                timecountdown = 8f;
            }

        }
    }
    void OnTriggerEnter() {
        //timecountdown = 8f;
        timer1 = 1;
    }

    void OnTriggerExit() {
        timer1 = 0;
    }
}

Answer 2

I really want to help you but I don't know what you want to do exactly:

You say:

Make a timer only decrease while staying in the trigger and reset when outside the trigger. When timer1 = 0, pause the countdown timer and set teleport to 0 When timer1 = 1, Set the timer to 8 seconds and start counting down, IF timercountdown = 0, set teleport to 1 and set Timer1 to 0. (TO reset the timer)

What I understand:

On entering the trigger:

• start or continue decreasing countdowntimer
• decrease countdowntimer while staying in trigger

On leaving trigger:

• pause decreasing, but do not reset
• set teleport to 0

If countdowntimer is below zero:

• set teleport to 1
• reset countdowntimer to 8 seconds
• continue decreasing?

Are there other rules for the teleport? You say if countdowntimer is zero you want to reset everthing. The teleport, too?

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

public class ProximityTeleport : MonoBehaviour {
    public float time;
    //public int timer1 = 0;
    public bool triggerActive = false;
    public int teleport = 0;
    public float timecountdown;   

    void Start () {
        timecountdown = 8.0f;
    }
    void Update () {
        if (triggerActive)
        {
            timecountdown -= Time.deltaTime;
            if (timecountdown <= 0.0f)
            {
                timecountdown = 8.0f;
                teleport = 1;

                // player has to re-enter the trigger:
                triggerActive = false;
            }

        } else {
            teleport = 0;
            timecountdown = 8.0f;
        }
    }

    void OnTriggerEnter() {
        triggerActive = true;
    }

    void OnTriggerExit() {
        triggerActive = false;
    }
}
