Hello,
I am creating custom explosion, but I don't want affect players that are behind wall.

PHP Code:

float traceDir[3];
SubtractVectors(explosionPos, clientPos, traceDir);
Handle trace = TR_TraceRayEx(explosionPos, traceDir, MASK_SHOT_HULL, RayType_Infinite); 
if(TR_DidHit(trace)) 
{
    //dmg...
} 


I don't know how to use traceray properly.
Thanks for all replies.
