What is zombie detector :D

if detector see you , hunters see appears over your head icon

but this bad :D

I assume you walk away from the original location of the detector spawn.

This means your detector.origin will remain where it was spawned, and the distance between THAT point and the zom will be less than 100.

work . delete players[i].detector
