How should i do it. Supposei have the following: int BULLET_SPEED=30; // 30 pixels/second // then on a frameDraw long deltaT=thread.getFrameTime(); // the time it took to move to a new frame, in millis int movement=(BULLETSPEED*deltaT)/1000; /// v*t = d The problem here is that movement is always zero because the devision is done with 1000 (1 second). So either i use this: int movement=(int)((BULLETSPEED*deltaT)/(float)1000); Which required FLOATING POINT calculation. Or i make the bullet speed a float. But this also requires floating point calculation. So how is it done, without the need of floating points? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
