Organisms and Behaviours

In biology, an organism is any individual entity that exhibits the properties of life. It is a synonym for "life form". - Wikipedia

Simulant StageNodes support pluggable controllers called Behaviours. Behaviours allow you to build modular logical components and then attach them to an Organism (an Actor for example). This essentially gives the Organism a life of its own.

Built-in Behaviours

Simulant comes with a number of built-in Behaviours and more and more of these will be added over time. Some of the built-in behaviours are:

• HoverShip - Makes the Organism hover above the ground and respond to controls.
• Airplane - Very basic flight-sim style controller.
• SmoothFollow - Primarily designed for Cameras this makes the Organism follow a target.

You can explore the full list of behaviours in the simulant/behaviours directory and subdirectories.

Rigid Body Physics

Simulant's rigid body simulation is implemented entirely using Behaviours. The key Behaviours to examine are:

• RigidBody - a dynamic physics object
• StaticBody - a static physics object
• KinematicBody - a kinematic physics object
• RaycastVehicle - a work-in-progress Behaviour for non-realistic car physics

All of these Behaviours require a RigidBodySimulation instance to function. The easiest way to get access to one of these is to make use of the PhysicsScene class when constructing your game scene.
