| >SDL provides several cross-platform functions for dealing with time. |
| It provides a way to get the current time, a way to wait a little while, |
| and a simple timer mechanism. These functions give you two ways of moving an |
| object every x milliseconds: |
| |
| <P |
| ></P |
| ><UL |
| ><LI |
| ><P |
| >Use a timer callback function. This may have the bad effect that it runs in a seperate thread or uses alarm signals, but it's easier to implement.</P |
| ></LI |
| ><LI |

| >Or you can get the number of milliseconds passed, and move the object if, for example, 30 ms passed.</P |
