I have some problem regaring collisions detection and check
I have walls with layer 1
I have a player layer 32
I have gifts layer 4
And a house with
Chimney layer 5
Roof layer 10
but when I play the game
the gift gets queue almost instantly sometimes (not every time, with the layer print "8")
The walls show layer 1
The chimney shows layer 16
the Roof shows layer 512
How come the layers doesn't show the right number?
And how come there's a random layer 8 interfering?

Thats not a random value, thats a bitmask, layer 4 bitmask is 3, 2 to the power of 3 is 8, so thats the value of gift.
If you just want to check if a layer number is enabled or not use get_collision_layer_value(layer) which returns a bool and expect an argument of the layer number (not bitmask)
lean tusk
Oh okay, so what I’m doing is not checking the layer used by said object? I will try the other version

Yep youre getting the collision layer value in its purest form.
lean tusk
how come there's something colliding with the 8 thing?
regal venture
Instead of checking for something vague, you should check what is colliding with the gift
lean tusk
or is it just colliding with the players collider? that gives the result of 8?
regal venture
I have no idea what your new code looks like or is it still the same
Do you know what bitmask is
lean tusk
havent done anything major
added _value to the code I already had
regal venture
Are you sure? get_collision_layer_value returns a bool so you should never print a number, what does your actual code looks like
lean tusk
extends Area2D
@onready var christmasgift: Node2D = $"../.."
@onready var collision_CB: CollisionShape2D = $"../CollisionShape2D"
@onready var collision_A2D: CollisionShape2D = $CollisionShape2D
func _on_body_entered(body: Node2D) -> void:
var layer = body.get_collision_layer()
print(layer)
if layer == 16:
Global.score = Global.score * 1.2
christmasgift.queue_free()
else:
Global.score = 0
christmasgift.queue_free()
You arent changing anything
lean tusk
this. and I put 16 since the collision gave me the 16 value
regal venture
The code still exact same
lean tusk
yes as of now, yes. I just came back to the computer 🙂
regal venture
if body.get_collision_layer_value(16):
else:
Thats pretty much all you need to do to check if a body has certain layer enabled
regal venture
yes as of now, yes. I just came back to the computer 🙂
Sure but you said you already changed it before.
regal venture
And? Whats the error?
regal venture
Well i am working off very vague context here so you need to be specific what is the intended result and whats actually happening
lean tusk
well. the 8 print, shouldn't be there for starters, it collides with what it looks like, the player, and according to the layer/mask config (as seen in pictures), they should not collide at all
regal venture
If you mean its still printing same number as before, i already explained it, youre not getting a layer number, youre getting a bitmask, im not explaining it anymore otherwise this is going on a loop.
The function doesnt do anything affecting the collision, it just does something after a collision.
A layer is a layer the object its on
Mask is the layer the object searches
lean tusk
yes that I know,
and I understand that I'm getting a bitmask (don't know what that is though),
I just need help to make my on_body enter to detect
if it's a wall
if it's a chimney or if it's a roof.
and also ignore the player
i thought it could be done with the body_get_... thing, but apparently that's wrong.
regal venture
yes that I know,
and I understand that I'm getting a bitmask (don't know what ...
Okay then expalain what is the goal here, what wants to check what. What is supposed to collide with what.
lean tusk
okay
so I throw out a gift (as seen in the video)
that gift has a Area2D.
and if the gift(area2d) is colliding with the chimney layer, give points
if the gift is colliding with roof layer, remove points
if the gift is colliding with the wall, remove points
in other words, if you hit something else than the chimney, loose points.
and also, I want to ignore that the gift somehow is colliding with the player
regal venture
Okay that gives me more context to understand what you actually wanted to do, give me a moment
For starters you should give all of your script a class name. e.g.
class_name Roof extends Area2D
This will be needed to compare if the gifts collide with that type
If you have done that let me know and i will tell you the next step
lean tusk
so I need to put a script on everything? The chimney for example does not have a script, neither does the roof or the walls
regal venture
Yes, even just a one line is fine, because we will need it to compare what we are colliding against
lean tusk
okay! so it just need the class and extends?
regal venture
Yes
Make sure to show me a screenshot of the script and the new setup so i can confirm you did it correctly
Keep in mind im about to off so you might want to wait until someone elses showup if i am unable to help later.
lean tusk
so I've made a script for the chimney, roof, and walls
added class_name to player(santa) and the gift collider (gift collision)
regal venture
And whats the class name of all of them.
Remember that in my prespective i dont know what your class name is.
Im really about to off so i'll just drop the info now and you'll figure the rest out, on your function for checking body you can now check if youre colliding against that type. e.g.
if body is roof:
elif body is chimney:
elif body is walls:
And so on
lean tusk
Oh okay!! Will try this soon 🙂
