Det kan faktiskt stämma, men vad vet jag inte. Problemet är att jag inte har någon riktig collision, den enda collisionen jag har nu är en massa if satser som kollar ifall fingret trycks ner på en viss position, för då ska den göra en viss sak. T.ex. Ifall man trycker ner fingret på samma position på samma position som skjut-knappen är på, då ska den skjuta.
Det här är hela min update, för jag tror att det är den som är oeffektiv och boven i det hela:

undvik foreach, iaf för stora listor, for är snabbare, speciellt precounted variabel. Använd inte distance, använd distancesquared och höj jämnförelsetalet till 2 också, om du ska kolla ungefärligt avstånd t.ex.
för o få lättare läslig kod kan du bygga en funktion som testar kollision mellan object. t.ex checkCollision(touchPosition, objectPosition, objectSize); i ditt fall, då du verkar byggt det så. annars som i alla andra trådar borde du objektorientera mer, använda klasser t.ex. men men...
annars kan det vara GarbageCollectorn som får spel. använder du mycket onödiga variabler?
