I tried to upload the in game script code to workshop but I was unable to do so. So I'm putting the source code here. Feel free to use it in your game. Copy the codes below and paste them to the programmable block. It should work for everyone. Hopefully. As of right now I don't know of any bugs that might occur on other people's games. It's still early and I may add features to it, but because it's not on workshop I may will have to update it manually.

/* Mazen's LCD Shield status display

This program takes the Alpha Shield's name and derive the shield strength
and output it to the LCD screen so that the user can read it and know the shield strength
This code can be expanded upon to have textures if I have them.

* Requirements for the code to work:
- shield generator with ":" at the beginning
- Text Panel with name "shield_LCD"
- timer block set to 1 sec interval
