You can randomize the value of a module property so that every agent gets a random value.
Using min/max value
Press on the 
button next to an overridable property. This activates the randomization mode, and it will show three new properties:
- Seed Value: the seed used by the random function.
- Min Value: the minimum value used by the random function.
- Max Value: the maximum value used by the random function.
Set the min and max values then atoms assign each agent a value inside this range.
Using values list
If you need to use specific values instead of a range, press on the icon, and it will show three new properties:
- Seed Value: the seed used by the random function.
- Randoization List: The random function assigns each agent a random value from this list.
