Is it possible to do a TR_TraceRayFilter, but have it go from one point to infinity & be able to detect all entities in it's path?

Example: If you have 2 players, and one stands in front of the other, the TR_TraceRayFilter will return only the first player entity in the line. How can I get both players if they are in that line?


If this is not possible with a single TR_TraceRayFilter, would there be a way to do it with multiple? My idea would be if you hit one entity at an endpoint, then start another TR_TraceRayFilter at the other side of the entity as a startpoint, and if that TR_TraceRayFilter hit's another entity...and so on.

Just pass an ArrayStack or ArrayList into the trace callback and fill it.

PHP Code:

void DoStuff()
{
    //...
    
    ArrayStack entStack = new ArrayStack();
    
    TR_TraceRayFilter(fPos, fAng, MASK_SHOT, RayType_Infinite, __TraceGetEntitys, entStack);
    
    while(!entStack.Empty)
    {
        int entity = entStack.Pop();
        
        //do something with entity
    }
    
    delete entStack;
}

public bool __TraceGetEntitys(int entity, int contentsMask, ArrayStack entStack)
{
    //...
    
    entStack.Push(entity);
    
    return false;
}

Thanks Timocop, I'll give that a shot, much appreciated!
