ped out of range problem

[HeavyMetal]

hey, im working on a resource to make high precision sniper peds, and i found out that if i get out of it's range it cant hit me(obvious), but when i come back to it's range (a area where it already hit me before), it dont shoot, i need to get close enought to its location so the ped appears again, otherwhise it simply dont respond to the fire command.

how can i make the ped work again without having to walk closer to make it load?
