Property | Type | Description
 --- | --- | ---
Variable | Fungus.Variables.FloatVariable | The variable whos value will be set
Min Value | Fungus.Variables.FloatData | Minimum value for random range
Max Value | Fungus.Variables.FloatData | Maximum value for random range

## Random Integer
Sets an integer variable to a random value in the defined range.

Property | Type | Description
 --- | --- | ---
Variable | Fungus.Variables.IntegerVariable | The variable whos value will be set
Min Value | Fungus.Variables.IntegerData | Minimum value for random range

Property | Type | Description
 --- | --- | ---
Text File | UnityEngine.TextAsset | Text file to read into the string variable

Variable | Fungus.Variable | Variable to read the value from. Only Boolean, Integer, Float and String are supported.

## Set Save Profile
