Summary

In this chapter, we learned about how to create timers and get random numbers.

• The Wait() Function The Wait() function allows you to pause the game for a certain amount of time. It takes game loops as input, which are 40 loops per second.
• Timers You can use the SetTimer() and IsTimerExpired() functions to start a timer and check to see when it goes off. SetTimer() takes an ID and a number of game loops before it expires, and IsTimerExpired() takes an ID and checks to see if the timer corresponding to that ID has gone off yet. Remember to reset the timer with SetTimer() if you want to keep it going.
• The Random() Function The Random() function will return a random number between 0 and the number that is passed into it inclusive. Remember to store that number in an int variable or you will lose it.
