im using c_trace a lot but now i am trying to use IGNORE_YOU but the flag doesnt work right i gues

i use c_updatehull(ent,1); for every ent

you = player1; // pointer is right
c_trace(camera.x,temp,IGNORE_PASSABLE | IGNORE_FLAG2 | IGNORE_YOU);

it seems to just to scan the you pointer instead of ignore

is there any explantion execpt the manual for this?
