| Sep 23, 2012 at 20:42 | comment | added | Bruce Dawson | The code above will fail miserably because it is using 'float' for game_time_elapsed. At that range the precision of a float is 256 s -- the next time that can be represented is 2^32+256. That's why I recommended two things: 1) Use a double so you have enough precision when the game has been running for a while. 2) Start at 2^32 so that the precision is consistent. The other reason to use 2^32 is so that you will instantly hit precision problems if you store elapsed game time in a float. | |
