If-else: If something is true, do something; if it s not true, do something

else. You can see an example structure of the if-else command in
Figure 14.7. Decisions are being made all the time in a computer game.
For example, consider a scenario where a player is moving toward some
enemies. If the player is within a certain distance of the enemies, the
creatures will attack. If the player is outside this range, the creatures will
continue to ignore the player. That is just one simple example of when
you may have if and if-else logic running within your game.

her favorite color, for example. In the switch statement, if the color is
red, you will give 5 points, if it
