what is the best way to implement ladder climbing in godot?

You'd want a collision shape that is close to the ladder to enable ladder mode. Then when entering that body/area, the player can push a button and than changes the state to climbing. When entering the climbing state, you snap the x/z position to the center of the ladder (you can compute this from the body/area position, plus some offset). Then use the arrow keys to move up and down the ladder similar to how you move on the ground.

A deceptively complex question, depending on how you want your ladder to work and your character model to interact with it. I'm assuming this is for your fps game. Would the character remain in first person view, and should your fps hands somehow interact with the ladder? Or would it be the scene-space character model interacting in with it? TPS view or still remain in FPS view while interacting?

the character would remain in fps view, no hands visible, the weapon will be retracted.. it should be as dynamic as possible , i mean when walking towards a ladder and slightly looking up at the ladder(or down, depending on the players' position(above or below the ladder))the ladder climbing should be triggered.

So in your movement/input code you would check if a variable named say is_climbing of type bool is true or not and based on that the forward and back keys would instead move the character upwards or downwards. The is_climbing boolean value could also be used to determine if the hands should be visible or not.

The state of the boolean could be toggled based on collision or area overlap signal from the player, so if body is ladder or such.

If you don't want to deal with a sea of if/elif/else mess using match instead should work too.

exactly what i thought. but i will need area triggers right? or not?

Assuming the ladder would have a collision mesh you could instead use collision. You'd just want the collision to basically check that the the object colliding is either in a group called ladders or has some meta attached to identify it by.
