I’m making a game where there are many Area2Ds of different countries, but I want to know the size of each country to calculate their surrender limit (bigger countries take longer to surrender, for example).

I don’t want to find the area of just one collision2D as some countries have multiple (see island nations, overseas colonies…), but looping that with the children could work if finding area using AREA2ds isn’t a thing.

I don’t want to simply use the outermost points of a collisionshape2D and draw a big rectangle, as it would make some countries way bigger than they really are (see especially the British and French empires)

Is it possible to find the area of an Area2D? If not, is it possible to calculate the area of CollisionShape2Ds (then I could just loop through the children).

p.s. Country size will not be the only factor for surrender limit, things like equipment stockpiles and something similar to war support in HOI4 might also affect it…
