Помогите плс спасить блюр а то я тупой не палучаеца
а вот как рендерица
вот что я напастил с exp 2.0 на 3.1 ошыбок нигде нету хз что делать
Java:
GaussianBlur.blur(2,2);
DisplayUtils.drawRoundedRect(x, y, width, height, radius, ColorUtils.rgba(5, 5, 15, 124));
GaussianBlur.startBlur();а вот как рендерица
