You have never defined energy bar or flashlight is.

if energy bar and flashlight are sprites u need to load the sprites in the script

4

Yes. Near the top of your script (outside any functions) put:

public var Flashlight:Sprite;

Now look at the script in the inspector. You’ll see a “slot” for a sprite. Drag your flashlight object into that slot.

5

No, wait. I misunderstood what you were doing. Flashlight isn’t a Sprite; it’s your script. “energy” is a variable in your script. You don’t need a “Flashlight.” reference to it at all.

energybar, you want that to be a Texture2D. Same as the code I posted first, except with Texture2D instead of Sprite.

    GUI.BeginGroup( Rect(40, 10, 218 * (energy/10.0) +35 , 100) );

I put it there … but now I shows

where is the problem?

This. You still haven’t defined energybar.
