PhysicsSystem:simulate_physics

Ticks the physics simulation. This involves:

Activating or destroying love.Body and love.Fixture objects.
Giving each Body a linear velocity matching its desired Movement.
Updating the Box2D simulation.
Calling on_collide / on_uncollide / on_activate / on_deactivate on the relevant Collider and Sensor components.

Usage

physics_system:simulate_physics(delta_time)

Returns

Name	Type	Description
`delta_time`	`number`	Duration to simulate, in seconds.

Examples

local MyScene = Class("MyScene", crystal.Scene);

MyScene.init = function(self)
  self.ecs = crystal.ECS:new();
  self.physics_system = self.ecs:add_system(crystal.PhysicsSystem);
end

MyScene.update = function(self, delta_time)
  self.physics_system:simulate_physics(delta_time);
end
