I want to be able to play a Falling and Rising animation whenever the velocity.y vector is either positive or negative, but its scalar by default.
#How do I make the velocity.y of my CharacterBody2D vector instead of a scalar?

Velocity is a vector, it's components are not. But why can't you check if it's positive or negative?

velocity.y is actually just speed
not a vecor, but a scalar
its just the magnitude of the velocity, but not its directiion
terse shard
how do you get this conclusion? velocity is a vector and velocity.y is one of its two component which can be positive or negative
coral beacon
how do you get this conclusion? velocity is a vector and velocity.y is one of it...
All the values its outputing are positive for me
terse shard
is it falling?
terse shard
then it supposed to be positive
terse shard
in godot and most program doward direction is y positive and upward is y negative
velocity.y went negative for a moment probably cause for a jump, then the gravity act upon it, pulling it down to falling and causing velocity.y to be positive
based on how i look at the default characterbody2d code
coral beacon
but its motion is upward until gravity's affect on the velocity overtakes the jump right?
so theoretically it should be negative until the character starts descending
coral beacon
im using godot's default gravity
terse shard
try showing the whole code
coral beacon
const SPEED = 300.0
const FRICTION = 1.5
const JUMP_VELOCITY = -600.0
const DASH_VEL = 200
var jumps_left = 2
@onready var animated_sprite = $AnimatedSprite2D
var pre_jump_finished = false
var pre_jump = false
# Get the gravity from the project settings to be synced with RigidBody nodes.
var gravity = ProjectSettings.get_setting("physics/2d/default_gravity")
func _process(_delta):
animation_handler()
func _physics_process(delta):
apply_gravity(delta)
input_handling(delta)
print(velocity.y)
func apply_gravity(delta):
# Add the gravity if not on floor.
if not is_on_floor() and !Input.is_action_just_released("ui_up"):
velocity.y += (gravity*0.5) * delta
elif is_on_floor():
jumps_left = 2
move_and_slide()
func input_handling(delta):
## JUMP ##
if Input.is_action_just_released("ui_up") and jumps_left>0:
velocity.y += JUMP_VELOCITY
jumps_left -=1
## Horizontal Movement ##
# Get the input direction and handle the movement/deceleration.
var direction = Input.get_axis("ui_left", "ui_right")
if direction:
velocity.x = direction * SPEED
else: ## STOPPING (FRICTION)
velocity.x = move_toward(velocity.x, 0, SPEED*0.1)```Where are you checking velocity.y?
coral beacon
Where are you checking velocity.y?
as in the print? its in the physics_process function
terse shard
on the jump code, instead of velocity.y += JUMP_VELOCITY, do velocity.y = JUMP_VELOCITY
and on apply_gravity(), when is_on_floor(), set velocity.y = 0
coral beacon
those two together make the player unable to jump
terse shard
right remove the later one about apply_gravity()
plucky olive
I mean where are you choosing the animation?
coral beacon
I mean where are you choosing the animation?
further down in the code, Im not showing it just to not waste your times with that
plucky olive
It could be relevant
coral beacon
not exactly since the choosing between what animation to show is just a conditional statement checking if the velocity.y is positive or negative
plucky olive
I don't see why this code you posted would be causing this. I have ot assume you have code elsewhere that is causing a problem
coral beacon
the value of any variables are not changed
func animation_handler():
# Y axis movement animations
if Input.is_action_pressed("ui_up") and is_on_floor() and velocity.x == 0: # WIND UP
animated_sprite.play("pre-jump")
if velocity.y >0 and !is_on_floor():
animated_sprite.play("Falling")
# if pre_jump == true:
# animated_sprite.play("Wind-up")
# X axis movement animations.
if velocity.x != 0 and velocity.y == 0:
animated_sprite.play("Run")
elif velocity.x == 0 and velocity.y ==0 and !Input.is_action_pressed("ui_up"):
animated_sprite.play("Idle")
if velocity.x >0:
animated_sprite.flip_h = false
if velocity.x <0:
animated_sprite.flip_h = true```there is he rest of it

Is there anything else in this file you've left out?
terse shard
i copypasted your code and tested it, i got how it expected to be like, 0 to jump_speed, then slowly moving toward positive as its falling
coral beacon
huh thats weird
terse shard
here where it transition from negative to positive, from jumping to falling, so there probably something else
terse shard
no i have it as capsule as well
coral beacon
the ground surface is a rectangle collider
i have literally
no other scripts on this project
coral beacon
is it because i used a rigidbody instead of a staticbody for the ground?
yup
changed that
and now its fixed
thanks
i saw you used a staticbody node
