Dobrý den, dělám hru v xna a mam tam příšery, kterým pomocí random gneruji náhoně jakým směrem se pohybují. Zde je třída příšer:

Při spuštění hry se podle mapy přidají do kolekce příšery instance této třídy. Potom se volá funkce update a draw. A náhodné generování směrů funguje nějak divně, protože při spuštění hry se určité skupiny příšer pohybují úplně stejně, což by podle mě dělat nemělo. Ale nevím jestli mám chybu v kódu nebo je chyba někde jinde. Prosím kdyby jste věděli co by mohlo způsobocat tento problém a případně i jak ho vřešit, prosím odpovězte. za odpovědi předem děkuji (když dám rnd = new Random() do konstruktoru dělá to také :( )
