Maybe create the plank just short of its full length then ingame, attach the final 2 end pieces where you can fix players to the ends then occilate to simulate swinging up and down.
The 2 ends are ent_created and vertex attached, the players are held to the 'platforms with vec_set.
Use the 'manual' Luke, the manual is your friend. 'Self reminder'
How about I animate the see-saw, and give it to animations and name them UP and DOWN. And then somehowe make the see-saw sensitive so it knows when it is up and down. Or I make the "jumper" sensetive so it "sees" if the see-saw is up or down.
