ControlAlways2D

Stores movement and rotation that will be applied to the entity every frame by sys_move_2d.

instantiate(game, [
    local_transform2d(),
    // Move the entity in its up direction every frame.
    control_always2d([0, 1]),
    // When moving, travel at the speed of 3 units per second.
    move2d(3, 0)
]);

Add ControlAlways2D to an entity.

direction param: Direction to move in the entity's self space.
rotation param: Direction to rotate to in the entity's self space: 1 = CCW, -1 = CW.

export function control_always2d(direction: Vec2 | null, rotation: number) {
    return (game: Game, entity: Entity) => {
        game.World.Signature[entity] |= Has.ControlAlways2D;
        game.World.ControlAlways2D[entity] = {
            Direction: direction,
            Rotation: rotation,
        };
    };
