How can I enable/disable a sprite from a script? Please Help

I’m trying to make a lock sprite appear when something is locked and disappear when it is unlocked.

Easiest way is a public variable in the script that you enable.

If using the 4.6 UI just do this.

public Image lockImg;

You also need this;

using UnityEngine.UI;

At the top of the script to use UI elements in the script. Then when you want it enabling…

lockImg.enabled = true;

and false to disable it. Once the script is saved simply drag the Image onto the slot in the inspector.
