Logic nodes are made up of input sockets, a node, and output sockets. Each node receives data through it's inputs, does predefined operations, then passes any processed data to it's outputs. Node trees may be as simple as a single node operating on it's default input values, or a complex graph in order to achieve program like operations.

---

Sockets form the link between nodes. They open a channel where a predefined data type may pass between nodes. In OgreKit sockets are in template form, meaning any C/C++ data type can be passed between connected sockets.

For example, some common types that may be used are:

• bool
• int
• float
• Vector3
• Quaternion,
• Matrix4
• GameObject
• GameObject Property

OgreKit limits connecting sockets to the same data type at each start and end point.

For example:

• float connects to float
• GameObject connects to GameObject

---

A node uses it's input values as parameters to it's function. Then returns the result to its outputs.

Nodes should consist of low level operations:

• Converting from a Quaternion to an Euler.
• Extracting individual components to math structures (vector3.x).
• Joining individual components to math structures (x,y,z to vector3).
• Extracting position/rotation/velocity from a game object.
• Extracting game object properties.

Nodes should also consist of higher level operations:

• Camera tracking
• State machine access
• Rotating, translating, applying linear/angular velocity.
• Tree grouping
• Ray casting
• Collision detection
• Create and destroy objects
• Sound playback
• Skeletal animation

Logic trees are only supported in C++ created applications.

The NodeEditor will be used to create nodal logic assets.

The C++ API is planed be bound to Lua and accessible scripts.
