Creates a new body.
There are three types of bodies.
- Static bodies do not move, have an infinite mass, and can be used for level boundaries.
- Dynamic bodies are the main actors in the simulation, they collide with everything.
- Kinematic bodies do not react to forces and only collide with dynamic bodies.
The mass of the body gets calculated when a Fixture is attached or removed, but can be changed at any time with Body:setMass or Body:resetMassData.
|
Making changes to a World is not allowed inside of the beginContact, endContact, preSolve, and postSolve callback functions, as BOX2D locks the world during these callbacks. |
Contents
Function
| Available since LÖVE 0.8.0 |
| This variant is not supported in earlier versions. |
Synopsis
body = love.physics.newBody( world, x, y, type )
Arguments
World world- The world to create the body in.
number x (0)- The x position of the body.
number y (0)- The y position of the body.
BodyType type ("static")- The type of the body.
Returns
Body body- A new body.
Function
| Removed in LÖVE 0.8.0 |
| This variant is not supported in that and later versions. |
Synopsis
body = love.physics.newBody( world, x, y, m, i )
Arguments
World world- The world to create the body in.
number x (0)- The x position of the body.
number y (0)- The y position of the body.
number m (0)- The mass of the body.
number i (0)- The rotational inertia of the body.
Returns
Body body- A new body.
Examples
love.physics.setMeter(40) -- meter is 40 px/units
world = love.physics.newWorld(0, 9.81*40, true) -- new world with gravity
body1 = love.physics.newBody(world, 250, 300, "static") -- new static body at x=250, y=300
body2 = love.physics.newBody(world, 251, 100, "dynamic") -- new dynamic body at x=251, y=100
