box2d-player
A small module that handles creating a player that can jump with Box2dweb. Handy for prototyping other parts of a physics-based game - if you're developing your own thing, you'll have better results writing something from scratch!
Installation
npm install box2d-player box2dweb-commonjs
Usage
b2Player = require('box2d-player)(Box2D)
Pass box2d-player
your Box2D
object and get back a player class in return.
var b2Player = require('box2d-player')(require('box2dweb-commonjs').Box2D)
player = b2Player(world[, options])
Creates a player instance, with its body attached to the world
. Takes the
following options:
-
data
: the user data to attach to the body. Defaults tonull
-
position
: the position to create the player at. Defaults to{x:0,y:0}
. -
jumpHeight
: the impulse to apply upwards when jumping. Defaults to10
. -
body
: a body you can use for the player - a default body will be created if not supplied. -
fixture
: a fixture you can use for the player - otherwise, a circle will be created for you.
player.jump()
Triggers a jump provided there's a physical body below the player and it's not
moving upwards. Returns true
if successful.
Right now you'll still need to control horizontal motion manually - you can do
this by changing the value of the player.body.m_linearVelocity.x
property.
