Java LibGDX 输入处理器多点触控

Question

for (int i = 0; i < 20; i++) {
    if (Gdx.input.isTouched(i)) {
        player1.touchPosition = new Vector3(Gdx.input.getX(i), Gdx.input.getY(i), 0);
        camera.unproject(player1.touchPosition);
    }
}

它正在工作，但我想将 InputProcessor 与 touchDragged 事件一起使用。

如何将此代码转换为InputProcessor？

Answer 1

   public boolean touchDragged(int screenX, int screenY, int pointer) {
    if (pointer < 20) {
                player1.setTouchPosition(new Vector3(Gdx.input.getX(pointer), Gdx.input.getY(pointer), 0));
                camera.unproject(player1.getTouchPosition());        }
    return true;
}
