Okay, i know there are other threads about this but i cant find a decent one. ive seen soem but they just are too confusing. well, ive gotten in some trigger_pushes and i cant quite get them to just shoot you up just like in the map co_freefall_rc1. if anybody could help me with the settings with the brush entity, that would help alot. thx :-*

The trick with vertical trigger_push movement is that the player needs a small initial upwards speed for it to work (don't ask why).
In half-life single player the effect of the alien blow thingies popping up wasn't just for looks; they also gave the player a little nudge upwards, which in turn made the trigger_push work.
So create some func_door that pushes the player a little upwards as soon as he enters a trigger_multiple placed over the jumppad.

And make sure to experiment with some pretty big numbers. A trigger_push with a push value of 3.5 isn't going to get you very far, think in more zeros.
