Help making a d-pad

Any help on how I can make a d-pad for a mobile game?

Thank you!

What do YOU mean by a d-pad for mobile?

Something like a virtual joystick, that moves the player, for example, around the level.

Here is one tutorial: How to Create a Mobile Touch 360 Joystick Controller in GDevelop 5 - Tutorial - YouTube

it didn’t help me at all!

I just want to move an object 8-directions.

It depends on how you move your character, but you need one object for each direction, and then, if touch is on object, move your character.
See the platformer project for an example with left/right.
