I'm developing a java 2D game, with a Board class and Mob(s) class. The board class has a thread that calls 'repaint()' every a specified delay, while the mobs class constructs a new thread for each of the mob spawned, which means when it does something, it ticks its time on its own. Simply said, I seperate the thread to enable frame rate setting. So i just need to only set how long does the Board thread sleep, like faster sleep means more frame rate (I use threads for this because a site says threaded timing can be made real precise). But then it means in a crowded in-game situation there would be a lot of thread running from every active Mob there.
My question: if i have this lots of thread running at the same time, wouldn't it be consuming a lot of system resources? And if yes, what is the best way round so I don't need to use threads? (just to note 2D game "crowded" situation can be "really crowded").
