func_movelinear

I searched how to do that for quite long already. Func_moveliniar and func_door desn`t work, because they only has 2 positions.

what i mean is how would you make a func_movelinear that starts at the bottom, goes (for example 300 hammer units) higher in a straight line, stays for a second or two, then ends up at the coordinates where it started?

If player will jump on top of the func_tracktrain, or func_movelinear, they will continue moving, but player will not move with them, and after few jumps he will fall of. And if engineer will build building on them, building will stand still, but train will continue moving. How to make player...
