How do I customize the image of the cursor?

Title says it all. :)

http://unity3d.com/support/documentation/ScriptReference/Input-mousePosition.html

Get position of the mouse, and then draw an object (GUI Texture perhaps) at that position...

Should work =).

Or if you want you can look at a free finished script I made for this question:

=) Enjoy!

Go to File > Build Settings > Player Settings > PC,MAC,LINUX > Select Cursor Texture :slight_smile:

Cursor.SetCursor(Texture2D,CursorMode)
