Hey!
First of all, thank you dearly for opening up this question.
I’m trying to recreate pong and make it two player. It’s for this reason that I decided to create one script - playerScript.gd - that handles the physics for both player1.gd and player2.gd, and then having different movement mappings between player 1 and 2.
I think the easiest way to show my problem is by adding the code.
**playerScript.gd**
```
extends KinematicBody2D
class_name player
export var speed = 300
#func _process(delta):
# pass
```
This is the script that I will eventually use to handle the collision detection for both players.
player1.gd
extends player
# Declare member variables here. Examples:
# var a: int = 2
# var b: String = "text"
func _process(delta):
var mov = Vector2()
if Input.is_action_pressed("p1_up"):
mov.y -= 1
if Input.is_action_pressed("p1_down"):
mov.y += 1
mov = mov.normalized() * speed
move_and_slide(mov)
move_and_slide(mov) is highlighted RED with this error:
Line 7 (UNUSED_ARGUMENT):The argument 'delta' is never used in the function '_process'.
Do I need to multiply something by the delta? I found that when I don't call the *classname player*, replace it with KinematicBody2D and include the *speed* variable in the *player1.gd* script, everything works fine and I'm able to move the player up and down.
The issue is this doesn't work when I try to call an external script.
What am I missing?

The error `Line 7 (UNUSED_ARGUMENT):The argument 'delta' is never used in the function '_process'.` isn't really an error; it's a warning. You can use the `_process()` function without using the `delta` parameter. The `move_and_slide()` function factors in `delta`, so you don't need to multiply it by anything.
I don't know what's the problem with your script, though. There does seem to be a problem with your inheritance of the "player" script. But I don't exactly know what.
