Hey, I'm in the process of making a portal bonus map pack and i was wondering if any mappers can help me with something. I want to spawn a portal directly beneith the player when they fall down a huge hole. Basically because this thing has an x,y area of 96,96 the player can move around during the fall. But i always want to make sure that they will land in a portal. How i've currently got it set up is that when they pass through 1 of 9 trigger_once then 1 of 9 portals will open up, the only problem is that there is still room for the player to fall and miss the portal. So i want it so that when the player gets to the trigger_once, it sends the portal a new x y location relative to the player (aka the players x y) and then that should maximise the chance of successfully going through the portal. So any ideas how to do this?

why dont you just make the portal big and put walls in the edges of the portal? you can even use invisible walls so it feels like you are in no where.
