#I always have problems with Area2D

You'll need to be more specific. What issues are you having, and how are you setting your collisions up? Remember that areas can report collision but they don't have a physical presence.

weary shuttle
#

Okay I guess I will make this a simple question. How to make collision detection with CharcterBody2D

#

@fierce scarab

fierce scarab
#

Did you add a collision shape to your characterbody2d?

weary shuttle
#

yep

#

@fierce scarab

fierce scarab
#

How are your collision layers set up?

weary shuttle
#

collision layers?

#

hells that?

fierce scarab
#

The collision layer is what your character sits on. Collision mask is what it recognises as an obstacle or interaction

calm berry
#

it would be easier if you follow a basic tutorial on setting up collisions

fierce scarab
#

If you have an object on a different layer, you need the corresponding mask or it won't detect it

@weary shuttle do you want me to make a video on it? Hopefully it can help

weary shuttle
#

yes please

past moth
weary shuttle
#

yep

#

am I even doing it right?

yeah, but you may need a couple things in addition to that, on the right you'll see the 'inspector' tab, look under that and expand the collision

#

for example, i left my layer / mask on 1

#

okay what to do next? my mask and collision is on 1

past moth
#

perfect, now what are you trying to collide it with? are you trying to take damage from an enemy?

#

Collision LAYER: where an object exists in the world

Collision MASK: what the object should collide with

weary shuttle
#

Jump_Boost

#

and can I make it so it detects if theres a tag on the jump_boost?

past moth
#

jump_boost sounds like an ability

weary shuttle
#

jump_pad

past moth
#

oh okay so when your character jumps on a jump_pad it flies up

#

that's what you're trying to achieve

#

?

weary shuttle
#

yep

past moth
#

Ahhh okay, 1 sec

#

what's currently on your script for your jump pad and your player?

weary shuttle
# 
extends CharacterBody2D

@export var speed = 300
@export var gravity = 30
@export var jump_force = 300

func _physics_process(_delta):
    if !is_on_floor():
        velocity.y += gravity
        if velocity.y > 1000:
            velocity.y = 1000
    
    if Input.is_action_just_pressed("Jump") && is_on_floor():
        velocity.y = -jump_force
    
    var horizontal_direction = Input.get_axis("Left", "Right")
    
    velocity.x = speed * horizontal_direction
    
    move_and_slide()


func _on_area_2d_body_entered(body):
    if body.is_in_group("jump_boost"):
        velocity.y = -600
#

I know it says jump boost but just think of it as jump_pad

#

@past moth ?

past moth
weary shuttle
#

func _on_area_2d_body_entered(body):
if body.is_in_group("jump_boost"):
velocity.y = -600

#

That is the jump_pad script

past moth
# 
   if body.is_in_group("jump_boost"):
   body.velocity.y = -600

in your player add this

func _ready():
    add_to_group("jump_boost")

try it and let me know

#

also chatGPT coding is a bit outdated

weary shuttle
#

yea I think you miss-understood. the

func _on_area_2d_body_entered(body):

the "body" is the Jump-Pad

#

so basically the player detects it

past moth
#

so again

func _ready():
    add_to_group("jump_boost")

add this in your player

weary shuttle
#

did nothing. the player stands on the pad like nothing

#

Thats the player
