Is there a function to detect if an specific addon is running?

[Minnax]

Or an arguement, anything of the sort? Or if not, a package?

[Ad Bot]

[Khepri]

Check the Guns Akimbo script, or the Flying Wheeled Jeep.

[Headcrab Zombie]

If you just want to see if it's running, there's isFunction, isPackage, or isObject
You could also check the value of $AddOn__["Addon_Name"]

If you want to make it require another add-on, check this

[CityRPG]

If you just want to see if it's running, there's isFunction, isPackage, or isObject
You could also check the value of $AddOn__["Addon_Name"]

If you want to make it require another add-on, check this

Would you happen to know for certain if $AddOn__["Addon_Name"] is unset or set to false/-1 if the Add-On was enable before it was deleted from the Add-On/ directory?
