This Firefly Engine object does almost all the work within these set of extensions. First, you should add one to the frame and then resize it to cover the frame. The area covered by this extension dictates the resolution of your 3D scene.

The Firefly Node Camera object is necessary to draw anything to the frame. It works similarly to how the Engine object works, except the area covered by the Camera object dictates where to draw the scene to (through the camera). Through this system, split-screen effects can be achieved, but usually the Engine object and your singular Camera will both be at the same point on the frame and both be of the same size.

The Firefly 2D Text object puts 2d text inside your 3d world useful for things like names above heads and other User Interface information.

The Firefly Image object puts images inside your 3d world useful for backdrops for all that User Interface information you have.

The Firefly Material Cache object represents and acts as an array of Materials. A Material has an Index that it resides at within a Material Cache object, and it can also have a name. Most node objects require one or more materials to render something other than a grey mass in the scene.

The Firefly Movement object is one of the most important objects in the FireFly set as it helps you move all your other nodes around.

With the Firefly Node Animated Mesh node you can insert an animated mesh into the scene. An Animated Mesh is animated across a number of Frames by calculating the position, scale, and rotation of the mesh's Joints using each one's collection of Key Frames across those Frames. 

So, an Animated Mesh might have many Joints, and each Joint can have many Key Frames of a Position and/or Scale and/or Rotation type. When the animation takes place, it calculates what Position, Scale, and Rotation each Joint should be set to at a given frame by working out each difference between the last and next Key Frame.

The Firefly Node Billboard object is like a 3d sprite: A 2d element, which always looks to the camera. It is usually used for explosions, fire, lensflares, particles and things like that.

The Firefly Node Dummy object isn't really an object at all, in fact it isnt anything and you will never see it in through the Node Camera but its incredibly usefull for holding data for example you could have players mark an area in your world and put a dummy node there and use its values in your calculations.

The Firefly Node Light object places various light sources such as spot lights or directional lights in your scene, Lights are often needed to brighten up a scene. Any Material (from the Material Cache object) that has its 'Lighting' setting set to true/on (which it is by default) means that it requires light to be rendered in some colour other than black.

With the Firefly Node Particle System you can insert a particle emitter into the scene. A Particle System node can be one of these types: Point, Box, Sphere, Animated Mesh Node, Cylinder, Mesh, Ring. These types describe the shape of the emitter. What is actually emitted is similar to a Billboard node object. 

A Particle System Node also can one or more Affecters. An Affecter is something located at a X,Y,Z position within the scene and will affect particles generated by the node object in different ways. The different types of Affecters are 'Attraction', 'Fade-Out', 'Gravity', 'Rotation', 'Scale'.

The Firefly Node Primitive object is capable of very quickly creating a mesh in the shape of standard objects such as cubes, spheres, arrows and planes.

The Firefly Node Static Mesh object isnt static as in not able to move its just static as in not containing any animations, most of your 3d objects will be static mesh's.

The Firefly Node Terrain object is capable of very quickly loading terrains and updating the indices at runtime to enable viewing very large terrains. It uses a CLOD (Continuous Level of Detail) algorithm which updates the indices for each patch based on a LOD (Level of Detail) which is determined based on a patch's distance from the camera.

The Firefly Node Text object lets you insert 2D text within the 3D scene. It works similar to the Billboard object in that it will always face the camera and the size of the text as it appears is not dependant on how close the object is to the camera.

This Firefly Node Water object for rendering an animated water surface mesh. Looks really good when a Material with Transparent Reflection is used.

This Firefly Sky object object is not quite a node object in that you can only have one in the scene, and it cannot be moved around. you can however choose to have a skysphere or a skybox which will allow your players to feel that the world is massive around them.

The Counter object : as its name indicates, this object holds numerical values and, at your option, displays it on the frame. The value can be displayed as a number, or as a percentage bar, either horizontal or vertical. This object is very useful for complex applications where you need to store data. You can add to, subtract from, and set a counter.

Tip : In the counter's properties, you can set the starting value, as well as the highest and lowest numbers it will be able to work with. It is very important to use these settings for percentage bars or you may not see them do anything at all when running your application.

The Lives object : displays the number of lives remaining for the player. It can display it as individual drawings, or as a number.

The Hi-Score object : automatically displays and manages a table of high scores for your game.

The Button object : this object displays a Windows' style button, a checkbox or a radio button. Very useful when you have to create interfaces. Buttons let your user/player control things.
