The idea is to create a “squash and stretch” animation.
$tween_squash.interpolate_property(sprite, "scale", Vector2(2.5, 3.5), Vector2(3, 3), .4, Tween.TRANS_SINE, Tween.EASE_IN_OUT)
And now, i want to know how to make the “collision with the ground” animation, that will be:
$tween_squash.interpolate_property(sprite, "scale", Vector2(3.5, 2.5), Vector2(3, 3), .4, Tween.TRANS_SINE, Tween.EASE_IN_OUT)
I want to do something like “the player touched the ground and will do this animation, only once.”
This is the result i want.

I created a variable called _was_airborne and used AnimationPlayer for the squashing while stretching based on the body velocity.y
Assuming you’re using a KinematicBody2D:
var _was_airborne = true
func _physics_process(delta):
if _was_airborne:
$AnimationPlayer.play('Squash')
_was_airborne = false
if not is_on_floor():
_was_airborne = true
This is my tree
┖╴KinematicBody
┠╴Sprite
┠╴Shape
┠╴JumpTimer
┖╴AnimationPlayer
and full script:
extends KinematicBody2D
var gravity = 1000
var speed = 100
var damping = 0.1
var jump_speed = 2000
var gravity_scale = 1
var velocity = Vector2()
var _was_airborne = true
func _physics_process(delta):
if Input.is_action_pressed('left'):
_move_left()
elif Input.is_action_pressed('right'):
_move_right()
if is_on_floor():
if velocity.y > 0:
velocity.y = 1
gravity_scale = 1
if Input.is_action_just_pressed('up'):
_jump()
$JumpTimer.start() # to increase gravity_scale
if _was_airborne:
_squash()
_was_airborne = false
else:
_apply_gravity(delta)
_stretch_based_on_velocity()
_apply_damping()
move_and_slide(velocity, Vector2(0, -1))
if not is_on_floor():
_was_airborne = true
func _move_left():
velocity.x -= speed
func _move_right():
velocity.x += speed
func _jump():
velocity.y = -jump_speed
func _squash():
$AnimationPlayer.get_animation('Squash').track_set_key_value(0, 0, $Sprite.scale)
$AnimationPlayer.play('Squash')
func _apply_gravity(delta):
velocity.y += gravity * delta * gravity_scale
func _stretch_based_on_velocity():
$Sprite.scale.y = range_lerp(abs(velocity.y), 0, 2000, 1, 1.5)
$Sprite.position.y = range_lerp(abs(velocity.y), 0, 2000, 0, -25)
$Sprite.scale.x = 1 / $Sprite.scale.y
func _apply_damping():
velocity.x *= 1 - damping
func _on_JumpTimer_timeout():
gravity_scale = 5
hello can i see your project cus i cant seems to get the same effects as you did probably have to do with the way u animate it in animation player
