## Level2XP
```pascal
function Level2XP(level: Integer): Integer;
```
Converts a level to the xp required for that level.

Example:
```pascal
  WriteLn Level2XP(70);
```

## XP2Level
```pascal
function XP2Level(xp: Integer): Integer;
```
Converts XP to the respective level.

Example:
```pascal
WriteLn XP2Level(100000);
```

## FormatNumber
```pascal
function FormatNumber(n: Double; dec: Byte = 3): String;
```
Truncates a number with a runescape like truncation.

Example:
```pascal
WriteLn FormatNumber(100000); //100k
```

## TColor.Random
```pascal
function TColor.Random(min: Byte = $80): TColor; static;
```
Returns a random `TColor` with a `min` value of brightness.
`min` is a `Byte` so it goes from $00 (0) to $FF (255).

Example:
```pascal
WriteLn TColor.Random();
```


- - -

## TColorArray.GetRarest
```pascal
function TColorArray.GetRarest(): TColor;
```
Returns a the rarest `TColor` in the `TColorArray`.

Example:
```pascal
WriteLn arr.GetRarest();
```


- - -

## TStringArray.AnyContains
```pascal
function TStringArray.AnyContains(value: String; caseSensitive: Boolean = True): Boolean;
```
Returns True/False if any String in the TStringArray contains `value`.

## Activity
Global `Activity` variable.

You can use this to handle the activity in your script.

The idea behind "Activity" is that it's a timer, by default that runs for 5
minutes. Everytime your script is considered "active" the timer is reset back to
the start.

If `Activity.IsFinished` ever returns `True` that means your script is inactive
or you are not restarting `Activity` properly.

By default, WaspLib will restart `Activity` for your when {ref}`XPBar.EarnedXP`
or {ref}`XPBar.WaitXP` return `True`.

For more custom ways of using this kind of activity tracker you need to
implement it but you could for example, in a fishing script, restart `Activity`
whenever you get a fish with:
```pascal
Activity.Restart();
```

Using `Activity` to shutdown your script or correct course is up to you.
A simple way to shutdown your script would be to add this to your main loop:
```pascal
if Activity.IsFinished then
  raise 'Script shutdown due to no activity detected for 5 minutes.';
```
