Exploring the Box2d World

Post by paclito »

I'm reading the documentation of box2d library at
http://www.box2d.org/manual.html#d0e544

and have see some very interesting functions to know what is in the world and what is at a rectangle in the world, the functions are
GetBodyList()
for a list of bodies in the world and

AABB Queries
for queries to the world, the result is a sort of list of bodies in the rectangle

I've not see this in our love library.....or i'm mistaked?

there is some function to do it? ...I have'nt see at docs sorry :-)

Uhm... I think this is the wrong section, but you can search and download "wrath" or "envy" in the Project and Demos section. (It's a game powered by Box2D)

At least GetBodyList() is easy to implement if you just keep a table around where you store all bodies:

Code: Select all

bodylist = {}
table.insert(bodylist, love.physics.newBody(...)
etc.
Help us help you: attach a .love.
