Timelines are a great way to make something happen in a predefined order and at a certain time. You can set it up to execute any code you wish, hence you can make a multitude of actions happen when you wish. As the set up uses only a single asset, editing and changing it can be done quickly. You could use a timeline to
Spawn enemies at set times.
Create a sequence of effects.
Spawn health packs.
Fire a spread of bullets.
Creating a Timeline
You can create a Timeline in the same way you would any other asset, as shown in Figure 26-1
