[HELP]Disabling script

How do I disable or return everything back to its original state without restarting the game or match? I am running multiple scripts and I want one to return everything to normal and for example disable only certain things e.g. press NUM_1 to activate undetectable mode or CTRL_NUM_1 to deactivate undetectable mode.

Whatever information you can give me would be much appreciated!

use scripts that can be de-activated as well

don't use scripts that CAN'T be de-activated

example: this CAN be de-activated http://www.mpgh.net/forum/754-payday...st-needed.html

and this one CAN'T (some of them can) http://www.mpgh.net/forum/754-payday...-snippets.html

look how normalizer.lua works in pptv4
