Hi, I want to make the whole game scene fade to white (or flash to white) when the player hits a mine, And then it transitions to game over scene.

I found several tutorial but they all consists of using GUITexture, which I can’t find in Unity 4.6…help?

Yep the new UI is the way to go. Add a canvas and add a panel to that canvas.

Leave the panels default color (should be white) but set the panels alpha to 255.

Add a CanvasGroup to the base canvas. Set its alpha to 0 and untick interactable and blocksRaycast.

Create a HitMine script I’ll use C#

using UnityEngine.UI;  // add to the top

// create a public CanvasGroup

public CanvasGroup myCG;
private bool flash = false;

void Update ()
{
    if (flash)
    {
        
        myCG.alpha = myCG.alpha - Time.deltaTime;
        if (myCG.alpha <= 0)
        {
            myCG.alpha = 0;
            flash = false;
        }
    }
}

Public void MineHit ()
{
    flash = true;
    myCG.alpha = 1;
}

Sorry for any typo’s, on my phone!

EDIT

This is the full script:

using UnityEngine;
using UnityEngine.UI;  // add to the top
using System.Collections;

public class FlashBang : MonoBehaviour {

	public CanvasGroup myCG;
	private bool flash = false;
	
	void Update ()
	{
		if (flash)
		{
			myCG.alpha = myCG.alpha - Time.deltaTime;
			if (myCG.alpha <= 0)
			{
				myCG.alpha = 0;
				flash = false;
			}
		}
	}
	
	public void MineHit ()
	{
		flash = true;
		myCG.alpha = 1;
	}
}

for testing I added a separate canvas and put a button on it and linked the OnClick to the script on the other, hidden canvas that had the script on it, it calls the MineHit function when clicked.

@AbnerWei… canvasgroup is a component so at your base canvas add a component of canvas group then assign it to public CanvasGroup MyCG…
