I want to make a wall jump system, can someone help me?

[MasterWhite]

I'm currently working on a game and I'm struggling to make a wall jump system, like the ones where you jump on a wall and instead of keep climbing up, you have to jump to the other wall in other to go up, can somebody help me? (If it isn't too much to ask, I would prefer have a code example + the explanation of how it works, thank you very much)

My movimentation and colision scripts was here

based on your code ..
i would go something like your basic jump shown above... only check for the wall on the X instead of the Y..

//jump
...
...

//wall jump
if place_meeting (x+1,y,obj_wall) and key_jump
{
vspd -=10
}
