Description
Query the world for all fixtures that potentially overlap the provided AABB.
(table) = b2.World:queryAABB(minx,miny,maxx,maxy)
Parameters
minx: (number) the minimal x coordinate of the query box
miny: (number) the minimal y coordinate of the query box
maxx: (number) the maximal x coordinate of the query box
maxy: (number) the maximal y coordinate of the query box
Return values
Returns (table) Indexed array of fixtures that potentially overlaps the provided AABB
Examples
Query specific area for bodies
--get all fixtures in this area
local fixtures = world:queryAABB(0, 0, 100, 10)
--check if there are any fixture
if #fixtures > 0 then
for i = 1, #fixtures do
--getting body of fixture
local body = fixtures[i]:getBody()
end
end
