World:update

Edit

Updates the World, advancing the physics simulation forward in time and resolving collisions between colliders in the World.

World:update(dt, resolver)

Notes

It is common to pass the dt variable from lovr.update into this function.

The default collision resolver function is:

function defaultResolver(world)
  world:computeOverlaps()
  for shapeA, shapeB in world:overlaps() do
    world:collide(shapeA, shapeB)
  end
end

Additional logic could be introduced to the collision resolver function to add custom collision behavior or to change the collision parameters (like friction and restitution) on a per-collision basis.

If possible, use a fixed timestep value for updating the World. It will greatly improve the accuracy of the simulation and reduce bugs. For more information on implementing a fixed timestep loop, see this article.
