2 years ago Platform behavior edge-cases like this are exceptionally difficult to deal with. There have been many stretching back over the years and I suspect it may not actually be possible to cover all of them. I'll look in to this but I'd advise trying to work around it instead as I can't guarantee if or when this could be resolved.

2 years ago Just a heads up for @eddynardo or anyone viewing this in the future, it looks like making very minor adjustments can fix this quirk. In the case of this example, simply tweaking Jump strength Platform behavior from 135 to 137 results in an immediate jump as soon as the block hits the second platform. Adjusting the Y position of the second platform by 1-2 pixels also fixes the issue.

2 years ago @samuelfine That was the first thing I did to my game a few months ago but unfortunately this doesn't solve the problem if you are using double jumps (since you can start your second jump from any height). My main issue now is that it happens with "coyote time" (when you allow the player to jump even a few frames after they missed a platform and they start falling) since the player is a few pixels lower than the usual jump, they can easily encounter the bug and get stuck unable to jump for a few frames. I managed to make a workaround that goes like this
If (player is not on floor && player is not overlapping floor && is overlapping floor at offset (0,1)) set player position to (self.X, Self.y+1)
the problem with this is that it doesn't work on 144 hz monitor for some weird reason but there are also some other things that work differently on 144 hz so I think I will try to lock it on 60 fps and stick with the workaround for now
Problem description
When a player with the platform behaviour jumps on a solid and touches it at the top of their jump height, the player will hover 1 pixel off the ground for about 0.5 sec before touching the ground again.
Attach a .c3p

Steps to reproduce
I made the player in the .c3p jump at the perfect time so it reproduces the problem automatically. Just hit preview layout
Observed result
Player is hovering 1 pixel off the ground and can't jump
Expected result
Player should touch the ground immediately after reaching it and be able to jump.
