World:update

Edit

Updates the World, advancing the physics simulation forward in time and moving all the colliders.

World:update(dt)

Notes

By default, the World updates at a fixed timestep. This means that the physics simulation will always update with a constant rate, for example 60 "ticks" per second. This improves stability of the simulation and decouples physics from rendering. Collider poses are automatically interpolated between the two most recent ticks, ensuring smooth movement even if the tick rate is lower than the rendering rate.

Fixed timestep can be disabled by setting the tickRate option to 0 in lovr.physics.newWorld. This will use a variable timestep where the dt value passed to this function will be applied directly to the physics simulation.

This function must be called from the last thread that called World:setCallbacks. If no callbacks are set, then this can be called from any thread.

Example

function lovr.update(dt)
  world:update(dt)
end
