I am having a bit of trouble with the above entity.
It is working in that it is spawning combine balls, but I am trying to get the balls it spawns to go up a tube (with a few right angles) once they have spawned and then into a "collector" where the balls will build up and up.
I have tried putting a func_conveyor in the tubes which doesn't work and a trigger_push which also doesn't work. The physics of the ball doesn't get it through the tube on it's own but neither have either of the obvious brush based entities.
