RayCast2D node - detect and filter areas

TwistedMind

Hello everyone,

I'd like use the RayCast2D node but i don't understand if i can filter or not the bodies/areas.

So, when i have created a factory, i build vehicle from this factory, when the vehicle spawn in that factory, it must move to the down-rigft. If an other unit is in front, i must send a signal to "push away" this unit.

But, the buildings has a area, like units, so how can i "filter" only the units to only detect them ?

And when i set detect bodies rather than areas, the "get_collider" method detect itself ?

Each units have a area node because they are added as instances.

EDIT: find the answer, an error in my code and about parents

You can add to group for every area or bodies.If so, it will distinguish which is tank and which is building.
