Hello everyone! I'm developing a platformer based on My Hero Academy and for some reason, my player is able to jump while touching a jump-through tile, when they should only be able to jump if they're on top of it.

Does anyone know why this happens?

Code for jumping:

--jump
if btn(❎) and player.landed then
 player.dy-=player.boost
 player.landed=false
end

Code for landing:

if collide_map(player,"down", flags.base) then 
 player.landed=true
 player.falling=false
 player.dy=0
 player.y-=((player.y+player.h+1)%8)-1

I was trying to run Pico8 with joystick on linux and wasn't being able to.

Until I saw this reddit post: https://www.reddit.com/r/EmuDeck/comments/17dohf8/comment/kspg7o8/

The fact that he was using a steam deck made me think our issues could be related. I then checked the config.txt and the following line:

// Specify which player index joystick control begins at (0..7)
joystick_index 1

Was defaulting joystick's behavior to player 2 instead of 1, even though the index is stated to start at 0 on the comment.

I then changed to this

// Specify which player index joystick control begins at (0..7)
joystick_index 0

And now I can get it to work. Maybe the default behavior was supposed to be joystick to player 1?
