Hello, I thought I had found a way to get this to work but without permissions its imposible as far as I can tell. Is there any chance you could add a permission to activate the plugin? 
I currently have the arena plugin with zone permissions, once someone enters the arena they are added to an oxide group with the Airstrike permission, I just need an on off perm for individual players. currently everyone on the map gets it.
I could be missing something if so just let me know, Thanks for your time

if you add them to the group when they enter the zone, then remove them from the group when they leave the zone? I believe there is a hook for exit as well as entrance.

Sorry re reading it i realise I wasnt clear, the remove perm is already set, the problem is that the kill streaks plugin is active for the entire server, I just want it available in the arena zone 

So you want a permission added to KillStreaks to toggle off and on for players? Would that solve this for you?

Yeah I beleve that would fix my issue, I just want kilstreaks to be available in the arena zone so i could add ther permto the arena zone groups , thanks for your quick replies

I'll try to code this up over then next few days. I've been working a lot of over time to deal with Covid stuff so not a lot of free time atm.

No problem at all, take your time. Just started learnig to code myself and its not easy.

Added an optional permission. Hopefully toggling that with the use permission set should allow you to do what you need to do.

Thank you so much, Do you have a paypal?

no, all my stuff is always free. Happy to help out.
