Example

The model below is of plant growth throughout the four seasons. The World trait temperature depends on the season. All of the seasons have different temperature ranges, using the 'set to' block to set a random temperature in that range. The plants in the simulation react both to the temperature of The World, and the precipitation that falls during winter and spring.
