Here is the proximity emitter script and texture, Now for public use!!! I have also made a benign version of the proximity emitter as well! :) Thanks to GoodMorning for improving and fixing some parts of the code!
If you find any issues or bugs with it post them here and i will try my best to help! :)
If you want to use this for your own map, the only thing you have to do is please give some credit in your map's description.
