Basic Usage Example

1. Create a component with GameContextProvider and StageContextProvider.

<GameContextProvider timeout={10}>
    <StageContextProvider config={{world: {width: 300, height: 300}, eventMode: "dynamic}}>
        <MyAwesomeStage />
    </StageContextProvider>
</GameContextProvider>

2. Create a component MyAwesomeStage.

export const MyAwesomeStage: React.FC<MazeHeroProps> = () => {
    const { status } = useContext(GameContext);
    const displayObjectConfig = useMemo(
        () => ({
            type: DisplayObjectType.SPRITE,
            url: "https://image_url",
            anchor: { x: 0.5, y: 0.5 },
        }),
        []
    );

    const [position, setPosition] = useState({x: 0, y: 0});

    useDisplayObjectFromConfig({
        ...displayObjectConfig,
        position: position
    });

    const onKeyDown = useCallback(
        (e: KeyboardEvent) => {
            switch (e.key) {
                case "ArrowUp":
                    setPosition({x: position.x, y: position.y - 1})
                    break;
                case "ArrowDown":
                    setPosition({x: position.x, y: position.y + 1})
                    break;
                case "ArrowRight":
                    setPosition({x: position.x + 1, y: position.y})
                    setDirection(90);
                    break;
                case "ArrowLeft":
                    setPosition({x: position.x - 1, y: position.y})
                    break;
                default:
                    break;
            }
        },
        [position]
    );

    useGlobalEventHandler({ event: "keydown", callback: onKeyDown, isEnabled: status === GameStatus.IN_PROGRESS });

    return null;
};
