Ever Wanted to Stop Time (or Slow It Down) in Your Unity Game? Here’s How!

Imagine creating epic “Matrix-style” slow-mo effects or freezing the action entirely for dramatic moments. Controlling time in Unity is not just cool — it’s incredibly simple! Here are two different ways to master time control.

1. Stopping Time Instantly

Unity’s Time.timeScale lets you freeze all time-based processes (movement, physics, animations). Perfect for pause menus or dramatic story pauses! Below is code snippet of how to stop and resume time instantly.

using UnityEngine;

public class TimeController : MonoBehaviour
{
    private bool isTimeStopped = false;

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space)) // Press Space to toggle time
        {
            if (isTimeStopped)
                ResumeTime();
            else
                StopTime();
        }
    }

    void StopTime()
    {
        Time.timeScale = 0; // Instantly freeze time
        isTimeStopped = true;
        Debug.Log("Time stopped!");
    }

    void ResumeTime()
    {
        Time.timeScale = 1; // Instantly resume time
        isTimeStopped = false;
        Debug.Log("Time resumed!");
    }
}

2. Gradually Slowing Time

Want smoother, cinematic effects? Gradually reduce Time.timeScale to create dramatic slow-mo sequences before freezing the action entirely! Below is code snippet of how to gradually slow and resume time.

using UnityEngine;
using System.Collections;

public class TimeController : MonoBehaviour
{
    private Coroutine timeCoroutine;

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space)) // Press Space to toggle slow-mo
        {
            if (timeCoroutine != null)
                StopCoroutine(timeCoroutine);

            if (Mathf.Approximately(Time.timeScale, 1f))
                timeCoroutine = StartCoroutine(ChangeTimeScale(1f, 0f, 1f)); // Slow time over 1 second
            else
                timeCoroutine = StartCoroutine(ChangeTimeScale(Time.timeScale, 1f, 1f)); // Resume time over 1 second
        }
    }

    IEnumerator ChangeTimeScale(float start, float end, float duration)
    {
        float elapsed = 0f;

        while (elapsed < duration)
        {
            Time.timeScale = Mathf.Lerp(start, end, elapsed / duration);
            elapsed += Time.unscaledDeltaTime; // Use unscaledDeltaTime to remain consistent even when time is slowed
            yield return null;
        }

        Time.timeScale = end;
        Debug.Log($"Time scale set to {end}.");
    }
}

Pro Tips:

• 🎵 Sync your audio! Adjust AudioSource.pitch or use AudioListener.pause for a more immersive experience.
• 🎥 For dramatic action, set targetTimeScale = 0.1f instead of 0 to keep the game in slow-mo rather than fully stopping it.
• 🛠️ Combine both methods for ultimate flexibility in your game design!
