I’m having some issues with move_and_slide function in a platformer game. For some reason, if character is standing on floor and is running into a wall, there’s some upward motion that seems to come out of nowhere and is being applied every other frame.
Here’s how it looks (notice movement vector printed every frame in the console):
Here’s the code for movement:
extends KinematicBody2D
const SPEED = 50
const GRAVITY = 250
const JUMP_FORCE = -130
const JUMP_CUT = -80
#var can_attack = true
var motion = Vector2()
var last_frame_motion = Vector2()
func _physics_process(delta):
update_motion(delta)
func _process(delta):
update_animation(motion)
func update_motion(delta):
last_frame_motion = motion
fall(delta)
run()
jump()
jump_cut()
motion = move_and_slide(motion, Vector2.UP)
print(motion)
func update_animation(motion):
$AnimatedSprite.update_anim(motion)
func fall(delta):
motion.y += GRAVITY * delta
motion.y = clamp(motion.y, -GRAVITY, +GRAVITY)
func jump():
if Input.is_action_just_pressed("ui_up") and is_on_floor():
motion.y = JUMP_FORCE
func jump_cut():
if Input.is_action_just_released("ui_up") and motion.y < JUMP_CUT :
motion.y = JUMP_CUT
func run():
if Input.is_action_pressed("ui_right") and not Input.is_action_pressed("ui_left"):
motion.x = lerp(motion.x, SPEED, 0.1)
elif Input.is_action_pressed("ui_left") and not Input.is_action_pressed("ui_right"):
motion.x = lerp(motion.x, -SPEED, 0.1)
else:
if last_frame_motion.y == 0:
motion.x = lerp(motion.x, 0, 0.12)
if motion.x > 0 and motion.x < 5:
motion.x = 0
elif motion.x < 0 and motion.x > -5:
motion.x = 0
else:
motion.x = lerp(motion.x, 0, 0.042)
I’ve even tried using move_and_slide_with_snap but had no success with it either.
Not sure what is the problem here
It’s quite an old thread, but I’m running into the same exact problem. If the OP is around, did you find what was causing this issue ?
