Translate object using local co-ordinates (Solved)

Question

Trying to make a character skip a distance by pressing a button. Example code:

if Input.is_action_just_pressed("action"):
    translate(Vector3(0,0,2))

The translate function is supposed to work in local co-ordinates, but it seems to move the character along the global Z axis.

I'm using Godot 3.0, which has the translateobjectlocal() function as well, but I have the same problem with it.

I tried combining things with Basis, including using get_transform().basis[0], no functional result.

Any ideas?

Normally a translation in an object should be always local. :-) It is local to its parent object. But that probably is not what you search.

This should do the job:

func do_translateZ(dist):
    var localTranslate = Vector3(0,0,dist)
    translate(get_transform().basis.xform(localTranslate))

The post is basically for Godot 2.x but 3d vector calcs should stay the same. (Just the demo project wouldn't run 1:1)
