# Coroutines

Coroutines are like functions except run in the background, while normal functions will interrupt the game until the function is completed. Coroutines can make use of the **wait** keyword in order to pause the function without blocking the game.

Below is an example of a coroutine that runs a cutscene. The wait calls allow the function to pause in the background without interrupting the main execution. To call coroutines you can call them just like any other function.

```csharp
coroutine Start()
{
    Cutscene.ShowDialogue("Levi1", "Levi", "Defeat the female titan before she escapes the forest!");
    wait 1.0;
    if (Network.IsMasterClient)
    {
        annie = Game.SpawnShifterAt("Annie", spawn.Position);
    }
    wait 4.0;
}
```

You can also use wait on coroutine function calls, to wait until that coroutine is done.

```csharp
coroutine Start()
{

    wait self.CutScene1();
    if (Network.IsMasterClient)
    {
        annie = Game.SpawnShifterAt("Annie", spawn.Position);
    }
}

coroutine Cutscene1()
{
    Cutscene.ShowDialogue("Levi1", "Levi", "Defeat the female titan before she escapes the forest!");
    wait 1.0;
{
```
