Ok, so Ive been trying diffrent methods, and somebody told me to use fastloop to make the player correctly align with the platform.
I'm having trouble doing this, when I try to the player sometimes go over the ground obstacle or doesnt align properly with it.
Im using + and - posistion co-rdinates of the player to move him, like ( repeat while left is pressed = set player X posistion +1 )
and Im using this for making the player detectable to ground obstacle ( [negate]player ground detector is overlaping a backdrop = Set player Y posistion +4 ) <- although this makes the player collide with ground obstacle,
Only problem is the player doesnt always align with the platform correctly. Any help?

Edit:N/m found a method, but if any1 has another plz let me know
