I wrote a script which creates an entity with a gun and sound from this archived thread :
The rat spawns after 3 seconds but doesn't chase me and this is what I get from ingame console :
L 04/27/2023 - 151:15: [AMXX] Run time error 10: native error (native "entity_range")
L 04/27/2023 - 151:15: [AMXX] [0] engine_stocks.inc::get_entity_distance (line 71)
Honestly, I don't know if the code will work even without the log error since I literally copied the think function to the end of script from this website :
and since get_closest_player() function didn't work I had to use chatGPT and come up with content of that function since there is no includes for it ("I'm a beginner scripter ikr :/ ")
