GUI and Floating Healthbars (week #11)

during this week I mainly worked on the GUI aspect of my turn based strategy game, for example floating  Health Bars for my units, backgrounds for the health bar,  text for when an attack misses and an icon for the poison status when a unit becomes poisoned. this is all handled by setting the screen position to MainCamera.WorldToScreenPoint and the position of the transform holding the script. a new rect is created at the screen position and tweaked in order to fit the right position for example this is the rectangle for my Health Bar:

Rect rect = new Rect (ScreenPos.x - 50, ScreenPos.y - 30, 100 / (100 / PlayerHealth), 15);

therectangle is also affected by the player's Health which causes it to reduced size the lower the players health becomes. A GUI.Box is created using the information shown in the rectangle but using its own GUIStyle variable allowing textures to be easily added to the health bar script.

I discovered how to created these floating GUI textures from this answer in Unity answers which I recommend you have a look at if you want to add a floating health bar to your game:

I also recommend reading the Unity Scripting API for camera.ScreenToWorldPoint which is linked here:
