Unlike TraceLine in L4D2 or TraceLineEx in TF2, MapBase, P2CE in Portal 2, the TraceLine() function does not take into account the collision type bitmask, making it very limited. I would like to ask to add or incorporate the TraceLineEx function or similar alternatives from Valve's other games that support VScripts, such as TF2, L4D2, or CS:GO.

This feature would enable us, modders, to create more advanced and interesting mechanics for Portal 2. If you look at the modder community of this game now, you can see that it is currently thriving more than ever. As a result, enthusiasts like me would be very grateful for the opportunity to fully use TraceLine in VScripts.
