I'm trying to make a coaster (sort of) similar to SkyScream, where the train passes the station several times and with a brake section at the top, it would work like this:
1-launch foward at a 37 mph speed, can't go through the first loop, returns to the station
2-launch backwards at a 62 mph speed, the train stops at the brake, that launches it fowards
3-launch foward at a 62 mph speed, the train goes through the skyloop and the brake doesn't activate
4-launch foward at a 37 mph speed, can't go through the first loop, returns to the station
5-launch backwards at a 62 mph speed, the train goes through the skyloop and the brake doesn't activate
6-launch backwards at a 37 mph speed, can't go through the first loop, returns to the station
7-launch foward at a 62 mph speed, the train goes through the skyloop and stops at the brake, that launches it backwards
8-launch backwards at a 37 mph speed, can't go through the first loop, returns to the station
Something like that... Now, the question is... How the hell I do it?
