There is a glitch where if the penguin jumps on top of the ice cube, they go to the right and then if you jump, they float up and don't come back down. I was wondering if someone could help make it where the ice cube and penguin can jump on top of each other as if they are solid blocks and stack. Thank you and I will give credit to your username and a follow if you want. Project is https://scratch.mit.edu/projects/1292795286 (it would help if you could remix so I could view the code and see what I did wrong. =]

its because in the code you are saying if both positions are equal and they are colliding increase both of their y velocitys by 10

if <<([Y v] of [penguin v]) < (y position)> or <([Y v] of [penguin v]) = (y position)>> then 

  
Code that makes y velocity higher
else
code that makes y velocity less
end

thats the issue

I see what you mean but it doesn't solve the problem of there being no collision when they jump on top of each other.

remove the or = and instead only add non set horizontal

define Fix leftcolisions -- run without screen refresh
repeat until <not <touching [penguin v] ?>>
change x by (-1)
end

I made another remix of your project: https://scratch.mit.edu/projects/1377449214/
I tried to make a new state of existence for the penguin that is true when it is stuck on top of the ice cube.
Seems like it is working. When either the penguin jumps or the ice cube jumps the penguin is put back into the unstuck state.

Wow i checked that out and that is insane. I would not have been able to find out how to do that. Thank you so much =]
