Expand description

Trait for mapping player inputs to physics forces/impulses.

Implement this to define how your game’s inputs affect physics bodies.

ⓘ
struct MyInputApplicator;

impl InputApplicator for MyInputApplicator {
    fn apply(&self, world: &mut PhysicsWorld, player_id: u8,
             body_index: usize, input: &FrameInput, dt: Fix128) {
        let body = &mut world.bodies[body_index];
        // Apply movement as velocity
        body.velocity.x = body.velocity.x + input.movement.x * dt;
        body.velocity.z = body.velocity.z + input.movement.z * dt;
        // Jump
        if input.has_action(0x1) {
            body.velocity.y = Fix128::from_int(5);
        }
    }
}

Required Methods§

Source

fn apply( &self, world: &mut PhysicsWorld, player_id: u8, body_index: usize, input: &FrameInput, dt: Fix128, )

Apply a player’s input to their controlled body.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
