# OnGameModeInit

## Description

This callback is triggered when the gamemode starts.

## Returns

This callback does not handle returns.

It is always called first in gamemode.

## Examples

```c
public OnGameModeInit()
{
    print("Gamemode started!");
    return 1;
}
```

## Notes

tip

This function can also be used in a filterscript to detect if the gamemode changes with RCON commands like changemode or gmx, as changing the gamemode does not reload a filterscript.
