Character doesn't move

So, I’m new using this engine and watched a tutorial to make a simple platformer, but when I use motion.x = MAX_SPEED it doesn’t move, I checked if I introduced something wrong in the code or keymaps and everything seems fine.

    var left = Input.is_action_pressed("left")
var right = Input.is_action_pressed("right")
var MAX_SPEED = 20
var motion = Vector2()

if left:
	motion.x = -MAX_SPEED
elif right:
	motion.x = MAX_SPEED
else:
	motion.x = 0

I’ll appreciate any help, thx.

Try putting ui_left and ui_right instead of left and right. Also, since you didn’t post the entire code, are you using motion to update the position of the character?

There’s nothing in this code that shows any kind of movement at all. All you’ve done is change the value of a variable called motion. To move something, you have to change its coordinates, which for 2D nodes, is represented by position.

If this is a kinematic body, then you’ll need to use the body’s provided movement methods - either move_and_collide() or move_and_slide()- to move the body and detect collisions.

See this tutorial for details on how to use KinematicBody2D:
