Function Documentation

move_and_collide()

void move_and_collide	(	trc_transform_t *	transform,
		const trc_world_position_t	velocity
	)

Moves the given transform in the specified direction, unless there is a wall within a distance equal to the transform's size

If that occurs, the transform will stop moving entirely

The velocity vector specifies both the direction and the speed of the transform

move_and_slide()

void move_and_slide	(	trc_transform_t *	transform,
		const trc_world_position_t	velocity
	)

Moves the given transform in the specified direction, unless there is a wall within a distance equal to the transform's size

If that occurs, the transform will slide across the wall (losing velocity according with the collision angle)

The velocity vector specifies both the direction and the speed of the transform

rotate_transform()

void rotate_transform	(	trc_transform_t *	transform,
		const float	rotation_delta
	)

Rotates the transform direction in the given signed angle

Note

The direction is determined by the sign of rotation_velocity, if it's positive then the rotation will be anti-clockwise, if it's negative then it'll be clockwise
