I need a fan-shaped collision detection and trigger some events, but I don't know which method is the most efficient.
s_scan or c_trace (Speed: low)
I currently use 7,8 c_trace(line)
but i need fan-shaped range. how to do it?

THANKS YOUR TIME

C_Scan is ok with SCAN_LIMIT and small range.
Or use a "Temp"-Model with EVENT_IMPACT and Group-Params.

NICE IDEA!!!
but big range use TRIGGER and trigger_range ?

Event_Trigger uses C_Move. I don t know, you need this. Just try out all
