I have a script for a simple 2D platformer in Godot 4 here, that I basically just stole from the documentation and altered some stuff. Sadly, it doesn’t work; the character seems to slowly clip into the ground until I can’t move anymore.
extends CharacterBody2D
var walk_speed = 300
var jump_speed = -400
var gravity = 100
func _physics_process(delta):
# Add the gravity.
velocity.y += gravity * delta
# Handle Jump.
if Input.is_action_just_pressed("Jump") and is_on_floor():
velocity.y += jump_speed
print(global_position)
# Get the input direction.
var direction = Input.get_axis("Left", "Right")
velocity.x = direction * walk_speed
move_and_slide()
When I run this code, the player character’s y coordinates slowly increase until my character is frozen.
Did you checked the Tilemap ?
There is a difference between godot 4.x and godot3.x in Tilemaps
Try the code in godot 3.x snd see if it works correctly
instead of giving a value to gravity try this # for godot 4.0 and higher
var gravity = ProjectSettings.get_setting("physics/2d/default_gravity")
for smooth movement try this
extends CharacterBody2D
var Acceleration = 0.25
var Floor_Friction = 0.2
var walk_speed = 300
var jump_speed = -700
var gravity = ProjectSettings.get_setting("physics/2d/default_gravity")
func _physics_process(delta):
# Add the gravity.
velocity.y += gravity * delta
# Handle Jump.
if Input.is_action_just_pressed("Jump") and is_on_floor():
velocity.y += jump_speed
# Get the input direction.
var direction = Input.get_axis("Left", "Right")
velocity.x = direction * walk_speed
if direction !=0:
velocity.x = direction*walk_speed
velocity.x = lerp(velocity.x,direction*walk_speed,Acceleration)
elif direction ==0:
velocity.x = lerp(velocity.x,0.0,Floor_Friction)
move_and_slide()
physics/2d/default_gravity actually made the clipping worse, because the default gravity was 960 and I used 100 in my code.
var walk_speed = 300
var jump_speed = -400
var gravity = 100
# var gravity = ProjectSettings.get_setting("physics/2d/default_gravity")
func _physics_process(delta):
# "Add the gravity only and only if character is in air."
if not is_on_floor():
velocity.y += gravity * delta
# Handle Jump.
if Input.is_action_just_pressed("Jump") and is_on_floor():
velocity.y += jump_speed
print(global_position)
# Get the input direction.
var direction = Input.get_axis("Left", "Right")
velocity.x = direction * walk_speed
move_and_slide()
I read in multiple forums that is_on_floor() only works when I have a downwards force pushing the object down. Would adding something like velocity.x += 0.1 to the horizontal movement work?

is_on_floor() works based on angle of tileset and detects whether the wall, slope or floor.
CharacterBody2D have builtin functionality of this.
It is working for me, So, I think it will work for you.
Thanks

Still gets stuck, is_on_floor() isn’t changing. Maybe it’s not a code problem; do you know any settings that may do this?

Try this and check the collision shapes and collision layers
Make sure that the character node and the Tileset can detect each others
