Hello everyone !
I use GDscript for coding and I'm trying to implement this kind of architecture :

First, I want my "Character.gd" can access (but not modify) the dictionnary contains in "Character_parameters.gd".
And then, I want to create three other KinematicBody2D which inherits from Character.gd. This way, I don't have to write again moving functions and player and clones move thogether in the same time. My questions are "is each scene a class callable by it name ?", "is there a way to implement interface or access to variable of another script?", "how can I make heritage?"
This is my severals script :
#Character_parameters.gd
const param = {
"WEIGHT" : 5,
"SPEED" : 200,
"JUMP_HEIGHT" : -200,
"JUMP_NB" : 2
}
And in this script I wanna use param dictionary instead of declare several constants.
I don't declared it in Character.gd because, I want parameter can be modify but not Character objects.
#Character.gd
extends KinematicBody2D
var motion = Vector2();
const WEIGHT = 5;
const SPEED = 200;
const JUMP_HEIGHT = -200;
const JUMP_NB = 2;
const UP = Vector2(0,-1);
func _physics_process(delta):
motion.y += WEIGHT;
if is_on_floor() : JUMP_NB =2;
if Input.is_action_pressed("ctrl_right"):motion.x =SPEED;
elif Input.is_action_pressed("ctrl_left"):motion.x =-SPEED;
else : motion.x = 0;
if Input.is_action_pressed("ctrl_jump") and JUMP_NB !=0:
if is_on_floor() or is_on_wall() :
motion.y =JUMP_HEIGHT;
motion = move_and_slide(motion,UP);
and then coding Clone_1 and Clone_2 extends both KinematicBody2D and Character.gd
