I tried to make a custom 3d player system, and it worked for the most part, till I added the stepping part, I tried a lot to try and make it work but it refuses to, I’m still somewhat new to Godot (I started at 4.5) so I need help if anyone can help.

I’m not sure what the problem is; you mention ‘stepping’, but I see ‘stepping’ nowhere in the code. Did you mean ‘sprinting’..?
The ‘sprint’ stamina will be reduced by 25, 60 times a second, from a maximum of 100, down to a minimum of 5. That’s not much time for sprinting..! Try a stamina maximum of 10,000, and see what happens..?
im new to this so i dont really know how to un-flatten it.
the problem is that i dont go up when i try to go on a surface little higher, what happens is that nothing happens and what i want is when you go on a surface a little higher it moves the player up
this post I previously made can help redo the collision so you can do it without a whole bunch of code checking that their is a stair (it is honestly not an easy problem to solve)
An easier solution if you’re ok with a little faking is to change the stairs’ collision shape to be a ramp. You can also play around with CharacterBody3D’s Max Angle setting. Though if you’re not careful, you can allow them to walk up walls. Still both are simpler solutions than raycasts. Also a capsule shaped collision shape that’s large enough to overcome the lip of a stair will solve the problem. So that’s three non-code options to explore.
The Player in my 3d Dungeon game has an upright ‘capsule’ collision shape, and has no trouble climbing or descending stairs between Levels in the Dungeon. There is no ‘bobbing’ motion on such stairs, but that’s OK for me. The Player can stop on the stairs, and turn around; there is no code required, just the standard ‘move and glide’. Just sayin’.
