I need help with the jump orb script for a geometry dash clone

Godot Version

extends Node2d

func _on_area_2d_body_entered(body)
if (body.name == “CharacterBody2D”)
body.velocity.y = -300

Question

Hi.
I am new to Godot and for basic training I’ve decided to create a Geometry Dash clone.
I’ve almost done everything except the JUMP ORBS.
can someone help me?
At the moment the orb script is just the basic jump pad script.
