The GameLance Terrarium community project is a great way for newcomers to learn game development as part of a much bigger community.
The GameLance Terrarium Plant Blueprint contains the building blocks used by the GameLance Terrarium project for plants.
The Plant Blueprint is the first in the series of Blueprints to be released and is essentially the starting point to get your Unity creatures into the Terrarium. If you want to focus only on the artwork The Plant Blueprint includes generic logic for you to use so that you don't have to write a single line of code to get your creations loaded while, if you are a programmer then you will be happy to find that you have fully programmable control over your creatures!
