To fix, make the player have gravity, now in the jump button: "When this is tapped: tell actors with tag: #player modify Y velocity to: (select a number), wait for 1 Second, modify Y velocity to: 0." And make the player have the "Player" tag, that should work.

here.
In the jump button add this code -
When a touch begins at this :
-Destroy this actor-
Now in the player’s code, do this.
When this stops moving,
Create Wall 4 in front of all actors at absolute position x( 0.071 ) y(4.313)
This code will disable the jump button from flying.
Hope this helps!
