Thanks!!
For the visual effect I used shaders with Godot themes.
Im using Godot 2 atm because Im working on a game for the last 2 years, and Godot Engine 3.0 was not available at the time. It is a customized version because I modified the source code of the engine and recompiled it myself. If you want to know more:
