Implementations

impl PhysicsWorld

pub fn set_scale_factor(val: f32)

Sets the factor used for converting physics engine meters value to pixel value. Default 100.0 is a good value since the physics engine can well simulate real life objects between 0.1 to 10 meters. Use value 100.0 we can simulate game objects between 10 to 1000 pixels that suite most games. You can change this value before any physics body creation.

pub fn get_scale_factor() -> f32

Gets the factor used for converting physics engine meters value to pixel value. Default 100.0 is a good value since the physics engine can well simulate real life objects between 0.1 to 10 meters. Use value 100.0 we can simulate game objects between 10 to 1000 pixels that suite most games. You can change this value before any physics body creation.
