How can I access built in functions in a inherited script

I have a KB2D root node Scene called “Character.tscn”, with a Script also called “”

Then I have an inherited Scene (from Character.tscn) called “Player.tscn”, with a Script that inherits from “”, called “”


extends KinematicBody2D

const VELOCIDAD = 10
const FRICCION = 0.1


extends “res://”

func _process(delta):

So far so good,BUT…
When I try to use for example move_and_slide in, GDScript doesn´t recognize it, as if it weren´t part of the built in methods. oddly enough it CAN print the variables assigned in the original script, so it seem to be inheriting just fine.

My question is: Do I need to do something else in order to get the kinematic functions, even if both scenes are KB2D?

I´ve seen some tutorials, but they don´t do anything else, besides setting the extend on line 1.
Seems something to simple to fail, yet it does. I´m using GODOT 3.1.1 by the way.

I’m struggling with the same problem, i can’t move_and_slide from an inherited scene; can you explain how did you arranged your node tree?, what tutorial did you see that implemented this way of handling movement? any help would be great, thanks.

I’m assuming “res://” has the Character class.

Weird, PLAYER should have move_and_slide. Could you run the code with PLAYER calling move_and_slide and post the errors?

Also, I’d like to suggest using class_name to tidy up a bit.

extends KinematicBody2D
class_name NewScript1

extends NewScript1
class_name NewScript2

Hey thanks for the advice and the swift response!

extends "res://Scripts/"

var movimiento = Vector2()

func _process(delta):

func actualizar_velocidad(delta):
	if Input.is_action_pressed("Arriba") and not Input.is_action_pressed("Abajo"):
		movimiento.y = clamp((movimiento.y -VELOCIDAD) , -VELOCIDAD_MAXIMA ,0)
	elif Input.is_action_pressed("Abajo") and not Input.is_action_pressed("Arriba"):
		movimiento.y = clamp((movimiento.y +VELOCIDAD) , 0 , VELOCIDAD_MAXIMA)
	else :
		movimiento.y = lerp(movimiento.y, 0, FRICCION)
	if Input.is_action_pressed("Izquierda") and not Input.is_action_pressed("Derecha"):
		movimiento.x = clamp((movimiento.x -VELOCIDAD) , -VELOCIDAD_MAXIMA ,0)
	elif Input.is_action_pressed("Derecha") and not Input.is_action_pressed("Izquierda"):
		movimiento.x = clamp((movimiento.x +VELOCIDAD) , 0 , VELOCIDAD_MAXIMA)
	else :
		movimiento.x = lerp(movimiento.x, 0, FRICCION)

Now i have actually tried it and it seem to work just fine, BUT the auto-complete keeps on suggesting methods for something else instead of KB2D:


no move _and_slide sugestion for example, even if it can run.
Why is this happening? is there anything I can do to fix it?

Those are Godot’s global stuff. They’ll be suggested in any gdscript.

@GDScript — Godot Engine (3.1) documentation in English

Can’t think of why your editor refuses to show move_and_slide. I’m using Godot 3.1.2.

You´re right, I suspected that much. I´ll see if updating it fixes anything.

It´s probably my rig, It has another bug in the project management screen were the UI redraws itself one input delayed… kinda hard to explain, but I read somewhere that´s a common bug on some W10 versions.
Damn Windows.
