Collisons and area2D

[neon breach]

I want to know if theres a way to make area2D only check certain collisons

[hollow rivet]

you can use layers and masks

in the inspector, look at the "collision" part. The "Layer" is this objects own position, the "mask" is the layers the area is gonna look out for

in this picture, for example, the Area 2D is on layer 1, and can detect objects that are in layers 1, 2 and 3

if there was an object set on layer 4, this Area2D wound't find it

and yes... it will detect itself

oh ok

and i could use a different area 2D to detect different collsions
