How do I make solid walls interact with the player?

I made a game using the joystick from this video: youtube.com/watch (I did not add the 8-Dir Movement alternative)

But there is one issue. The player goes straight through walls (Using a Tilemap). I tried adding Solid behavior to both, but that didn't work. Does anyone know how to make the player not phase through the wall?

You need to use 8direction and move the object using "Set vector" actions. Then it will be stopped by solid.

There are a few other examples of virtual joystick here:
