Good evening SA-MP peoples,

I've been wondering how do i do so when i pass a red circle, either on foot, bike, car or any other vehicles that it drops off the materials packages so i recieve my materials from materials running?

Currently im using /materials deliver wich i want to change to just a red circle when you either enter it or goes throght it, it delivers the packages.
But im unsecure on how to do it, can anyone out there help me ?

I've never worked with red circle before so i might be a bit newbish on it.

Thanks
