Спрайт, всегда повернут к игроку

hohserg · 25 Апр 2015

Как сделать, чтобы был у моба спрайт, повернутый всегда к игроку, и если моба видят 2 игрока, то им обоим кажется, что моб повернут к ним?

оо, спасибо, про него тоже забыл)

Рендер, а не эннтити.

hohserg · 26 Апр 2015

Он, вроде, это и дал...

Ты кидаешь энтити и спрашиваешь, где рендерится -_-
