Class: R3d.World

Description

Creates a new ReactPhysics3D dynamics world. 

r3d.World.new(gravityX, gravityY, gravityZ,params)

Parameters

gravityX: (number) the gravity on the X axis (m/s^2), default=0
gravityY: (number) the gravity on the Y axis (m/s^2), default=-9.81
gravityZ: (number) the gravity on the Z axis (m/s^2), default=0
params: (table) the world cutsom parameters, OPTIONAL & !EXPERIMENTAL!, possible values are:

  • persistentContactDistanceThreshold, default=0.03
  • defaultFrictionCoefficient, default=0.3
  • defaultBounciness, default=0.5
  • restitutionVelocityThreshold, default=0.5
  • isSleepingEnabled, default=true
  • defaultVelocitySolverNbIterations, default=6
  • defaultPositionSolverNbIterations, default=3
  • defaultTimeBeforeSleep, default=1 (sec)
  • defaultSleepLinearVelocity, default=0.02
  • defaultSleepAngularVelocity, default=(3.0) * (PI_RP3D / (180.0))
  • cosAngleSimilarContactManifold, default=0.95

Example

require "reactphysics3d"
local world = r3d.World.new(0, -9.8, 0, {
	isSleepingEnabled=false,
	defaultVelocitySolverNbIterations=20,
})
