GUI.DrawTexture and assign it to a variable?
Hi guys, I'm just trying to show a health bar in a fixed screen coordinate, but to manipulate the health bar I need to assign it to a variable. I'm drawing the bar with GUI.DrawTexture, and the problem is that I'm trying to assign it to a variable for hour with no sucess. I ever get this error: *Cannot implicitly convert type 'void' to UnityEngine.GUITexture'*. I think that the problem here is the variable type that I'm using, but I was unable to find the proper type. Here's a little bit of my code: ---------- public Texture2D healthSpr; public Texture2D healthbarSpr; public Color healthColor; private GUITexture healthUI; void OnGUI() { GUI.DrawTexture (new Rect (50, 15, 500, 100), healthSpr); healthUI = GUI.DrawTexture (new Rect (50, 15, 500, 100), healthbarSpr); } ---------- I only need to assign the second GUI.DrawTexture` to the healthUI variable. Any help will be appreciated.
Thanks in advance.
GUI.DrawTexture is a method that is used to draw a texture on OnGUI. It's return type is void and because of that you can't assign it's return value to a variable, as you are trying to do.
You will have to store the actual values used to create the DrawTexture and modify those instead.
Thanks, but can I change the color and the scale after the texture is drawn?
Yes absolutely. The GUI is drawn once per frame and can be manipulated between each frame in whatever matter you like.
