- There is isFrozen, isStatic and isDynamic but no way to set them.
- Could you add a way to get all bodies in the world as an array? I know you have a way to get the number of bodies but a way to get all bodies as a table would be awesomesauce.
- Prismatic Joints, Gear Joints, Pully Joints?
- Like you said in a previous post, some sort of "traces" would be great. Basically checking if a line hits a body, then it returns the body (and World).

Just the body?
It should return (a table of):
- Body hit
- Shape on said body
- Position at which the line hits
- Direction perpendicular to the surface hit

Great initiative, Kudomiku.
- setFrozen etc. does not exist.
- With some hacking it would be possible to get all the bodies as a table, but I can't see why this is needed. Bodies should be stored in the Lua game code.
- Prismatic joint already exists, the others will be added eventually.
- Traces could be useful, though the function would return a table of shapes, not bodies.
These kinds of requests were just what I hoped for, so keep it up (but don't overdo it
).

Thanks Rude, if it's not too much to ask could you add a way to make two entities not collide in the next release?
body:setNoCollide(otherBody);
Thanks.

Returning false on a collision callback should have the entities not collide, too.

Note: bodies do not collide, shapes do.

Thanks.
Have you looked at shape:setCategory and shape:setMask?

Checked Box2D docs, it's possible, but needs separate callback.

A nice effective way to remove bodies would be nicey nicey. My current method is to move the object outside the world and remove it from the render que.
