I am making progress on my game; thank you to everyone who has helped me. I have found that there is a new problem I need to solve. Now when I merge two tiles, the resulting new tile will fall through the floor or the wall of the game. Does anyone have any suggestions? Thank you in advance.
So I went into your game and found 3 things that were making your game working in a way that you didn’t want it to.
The first step to fix this is:
Make all number objects with this physics settings.
(x) Movable
( ) Affected by gravity
( ) Is solid
(x) enable collisions
The second step is:
Delete these two behaviors inside of the “Click and Drag” Bundle.
Third step:
Add this system to all of your number blocks. This will make them have no momentum or movement force on their own.
I am still working on my game and I tried what you showed me, but the tiles are still going through the walls. I might be missing something, but I’m going to keep trying. If you spot anything else that I should try, please let me know. Thank you!
