I have a suggestion...
Maybe change c_scan to not scans through walls all the time but only with some mode like ignore_blocks?

Because now is hard to make detection system with walls using cone...
trace is only line/box-line, trigger is full sphere... only scan using cones like "if I can see you" (it means f.e. 120 degrees horizontal and 50 vertical depends of my pan/tilt) but through the walls

what you think about it?

well you can make your own function that first scans for entities and then does a trace, if they are both successful then it didnt go thru a wall.

I know that
but with simple mode "ignore_blocks" (or not) will be easer

yeah, ofc there are 100 suggestions how to implement some special features, but i guess the most things just a few people need, so it don't make sense to add them...and if you are able to do it with a 3 lined function....do you really need it? Ö_ö

why not if every function have this mode (ignore_passable / walls) why c_scan hasn't?
