Hello! I am currently trying to create a system in which the player can choose between multiple bodies within an area 2D. I am currently using the get_overlapping_bodies() function to do this, and was wondering how it determines the order of the list of bodies.
For insight, this is the code I am using right now -I am currently assigning an ID to each of the bodies, so I can select based on the value of a counter which changes with keyboard input-
func assignIDs():
var ID = 0
for bodies in Area.get_overlapping_bodies():
bodies.ID = ID
print(bodies.ID)
ID += 1
maxID = ID
func select():
owner.movement_velocity = Vector2.ZERO
canHit = whipRange.get_overlapping_bodies()
if Input.is_action_just_pressed("Right"):
targetBody += 1
elif Input.is_action_just_pressed("Left"):
targetBody -= 1
targetBody = clamp(targetBody, 0 , maxID)
for bodies in canHit:
if targetBody == bodies.ID:
bodies.modulate = Color(1,0,0,1) #Visual aid to show which body is selected
else:
bodies.modulate = Color(1,1,1,1)
I am currently using these two snippets of code (first is in a separate function, unimportant right now) to select a body out of the list, but would like to know how the function determines the order so I can have it be more polished in the final product 
Thanks!
