swap_positions

Function

swap_positions(
    state_1: State,
    state_2: State,
    t_start: float,
    t_end: float,
    easing: Optional[Dict[str, Callable[[float], float]]] = None
) -> Tuple[List[KeyState], List[KeyState]]

Swaps the positions of two elements with linear interpolation.

Returns two keystate lists for two separate VElements. This function assumes both State objects have a 'pos' attribute of type Point2D.

Parameters

state_1: The base State of the first element.
state_2: The base State of the second element.
t_start: Start time of the swap.
t_end: End time of the swap.
easing: Optional easing dict for position transitions.

Returns

Tuple of (keystates_for_elem1, keystates_for_elem2)

Examples

ks1, ks2 = swap_positions(circle1, square2, t_start=0.3, t_end=0.8)
    elem1 = VElement().segment(ks1)
    elem2 = VElement().segment(ks2)
