UNNEEDED HELP, GO!
So, @j_u_d_e, you want to make a ladder?
First, make a ladder sprite. Make it nonsolid, but enable collisions. The next part’s more complicated.
See the L, L, and G? That says Ladder, Ladder, and Ground. Basically, you want the first raycast for the ladder pointing at 270 degrees, and the second one at 90 degrees. The ground should also be at 90 degrees, but shorten it to 16 length.
Basically, if the raycast is missing both ladders, it turns off the climb switches and turns on the jump on the up button (oh yeah, the second up has a repeat on it. Remember that.)
However, if it is hitting a ladder, it turns off the jump switch and turns on the climb up/down switches. It also turns on the motor that makes you fall somewhat slow.
Stay magnificently dank,
