# bullet-physics-love2d
Bullet Physics for LÖVE, in development.
How to use:
``` lua
local love_bullet = require 'love_bullet'
```
__API:__
##### World
``` lua
local world = love.physics3d.newWorld(gx, gy, gz)
world:update(timeStep, maxSubSteps, fixedTimeStep)
world:update(timeStep, maxSubSteps)
tableofRaycastHit = world:raycast(vec3Origin, vec3Direction, maxDistance)
world:addRigidBody(rbody)
world:addCharacterController(character)
world:removeRigidBody(rbody)
world:removeCharacterController(character)
```
##### CollisionObject (Base class for RigidBody and GhostObject)
``` lua
local collision_object
collision_object:getTransform(table)
collision_object:setTransform(table)
collision_object:setUserData(table)
collision_object:getUserData(table)
-- parameters for callbacks: function(tableofContactPoint, bodyA, bodyB) end
collision_object:setCallbacks(begin_contact, ongoing_contact, end_contact)
collision_object:activate(force)
collision_object:isActive()
collision_object:setAnisotropicFriction(vec3Factor)
collision_object:setContactProcessingThreshold(value)
collision_object:setRestitution(value)
collision_object:setFriction(value)

collision_object:setContactStiffnessAndDamping(stiffness, damping)
collision_object:setHitFraction(value)
collision_object:setCcdSweptSphereRadius(value)
collision_object:setCcdMotionThreshold(value)
shape = collision_object:getCollisionShape()
xf, yf, zf = collision_object:getAnisotropicFriction()
boolean = collision_object:hasAnisotropicFriction()
value = collision_object:getContactProcessingThreshold()
value = collision_object:getRestitution()
value = collision_object:getFriction()

```
##### RigidBody
``` lua
local rbody = love.physics3d.newRigidBody(shape, mass, matrix)
rbody:setDamping(lin, ang)
rbody:applyForce(vec3LinDamping, vec3AngDamping)
rbody:setAngularFactor(vec3Factor)
rbody:setLinearFactor(vec3Factor)
rbody:setKinematic(boolean)
rbody:setLinearVelocity(x, y, z) -- need fix: change to parse vec3
xv, yv, zv = rbody:getLinearVelocity()
```
##### GhostObject
``` lua
love.physics3d.newGhostObject(shape)
```
##### Shapes
``` lua
love.physics3d.newBoxShape(halfSizeX, halfSizeY, halfSizeZ)
love.physics3d.newCapsuleShape(radius, height)

local character_controller = love.physics.newCharacterController(ghost_object)
character_controller:jump(vec3)
character_controller:setWalkDirection(vec3)
character_controller:setGravity(vec3)
character_controller:setUp(vec3)
character_controller:setMaxJumpHeight(value)
character_controller:setMaxPenetrationDepth(value)
value = character_controller:getMaxPenetrationDepth()
boolean = character_controller:onGround()
```
__Others:__
##### ContactPoint
``` lua
x, y, z = point:getPositionA()
x, y, z = point:getPositionB()
value = point:getDistance()
```
##### RaycastHit
``` lua
x, y, z = hit:getPosition()
x, y, z = hit:getNormal()
value = hit:getDistance()
value = hit:getHitFraction()
collision_body = hit:getCollisionObject()
```
