added the ability to speed up the simulation

without losing accuracy

[graceful herald]

5x simulation speed

here is the script:

extends RapierPhysicsState

func _ready():
    await get_tree().physics_frame
    var box = BoxMesh.new()
    box.material = StandardMaterial3D.new()
    box.material.albedo_color = Color.RED
    var box_shape = BoxShape3D.new()
    while true:
        await get_tree().create_timer(0).timeout
        var body = RapierPhysicsRigidBody.new()
        body.global_position = Vector3(randf_range(-5, 5), randf_range(5, 10), randf_range(-5, 5))
        var collider = RapierPhysicsCollider.new()
        var mesh = MeshInstance3D.new()
        mesh.mesh = box
        collider.shape = box_shape
        body.add_child(mesh)
        body.add_child(collider)
        add_child(body)
