DarkRP Questions

Hey, I run a DarkRP server, and am getting close to finalizing everything, but there’s a few things I’m confused on, and was hoping you guys could help me.

The things I need help with:
I need to know how to decrease wait time between ammo purchases. Currently when you buy ammo from the F4 menu you have to wait around a second and a half between purchasing them. I’d like to make it less of a delay.
I’d also like an addon or something that would remove blood decals and fix broken windows every 10 minutes or so.

If anyone is willing to help me with this, please let me know.

Site note: I DO NOT WANT THE ADDON TO REMOVE PROPS

Sorry to put you on the ground right away, but this is a place to ask for help with scripts.
And to be specific, it’s a place where scripters come to ask for help fixing their issues, finding a better way to do what they want to do or finding a way to do it in general.
If you have any DarkRP releated question, you should ask the author or someone else that has more knowledge than you.

Entity purchase timer is set to 2 seconds in the gamemode files.

DarkRP 2.5.0 has a config setting to automatically clean decals every xx seconds, use it.
