I’ve recently started trying game dev and I’ve followed a couple tutorials, some on youtube and some on this forum, I was trying to implement a variable jump (like if you press short your jump is short) but I came across a glitch where if you spam the jump button, you slow fall, how can I fix this? here is the entirety of my code, again, if some of the code is unnecessary, I would love some feedback as I literally started coding last week



const SPEED = 130.0
const JUMP_VELOCITY = -260.0
@onready var animated_sprite_2d: AnimatedSprite2D = $AnimatedSprite2D
var can_jump = true
@onready var coyote_timer: Timer = $CoyoteTimer


#function for jumps AKA that one thing that makes you jump
func jump():
	velocity.y = JUMP_VELOCITY
	can_jump = false
	

func _physics_process(delta: float) -> void:
	# Add the gravity.
	if not is_on_floor():
		velocity += get_gravity() * delta
	#restores your jumps when on the ground
	else:
		can_jump = true

	if (is_on_floor() == false) and can_jump == true and $CoyoteTimer.is_stopped():
		$CoyoteTimer.start()

	# Handles the jump
	if can_jump == true:
		if Input.is_action_just_pressed("Jump"):
			jump()
	else:
		if Input.is_action_just_released("Jump") or is_on_ceiling():
			velocity.y *= 0.5

	#this is the player movement code
	var direction := Input.get_axis("Walk_left", "Walk_rigth")
	if direction:
		velocity.x = direction * SPEED
	else:
		velocity.x = move_toward(velocity.x, 0, SPEED)

	move_and_slide()
	
	# This code handles the sprite direction and animation playing
	if direction > 0:
		animated_sprite_2d.flip_h = false
	elif direction < 0:
		animated_sprite_2d.flip_h = true
	if is_on_floor():
		if direction == 0:
			animated_sprite_2d.play("Idle")
		else:
			animated_sprite_2d.play("Walk")
	else:
		animated_sprite_2d.play("Jump")


func _on_coyote_timer_timeout() -> void:
	can_jump = false

velocity.y is getting halved every time the jump button is released. You should check if velocity.y < 0.0 before this (so it can only happen when moving upwards, not while falling down).
And you probably want to also limit this to one time per jump (by using an additional bool), because otherwise the player could still reduce the jump height by spamming the jump button while moving upwards. (Which probably is less of an issue though.)

Thank you so much! I actually ended up coming up with a another solution where I used a variable that gets set to true every time the player touches the floor and false every time the player short jumps, still, thank you!
