Shaders

Introducing shaders out here


When rendering a scene the geometry and the texture information of the scene is sent to the graphics card for processing. In the past, a few graphics card supported the hard wired algorithms to process this information or data of the scene. This was known as the fixed function pipeline. The programmer could only use these fixed states and he had no control on the uniqueness of the game. All games looked the same irrespective of the nature of the game.

For example, given a piece of clay one could design a tank, a human figure, or a ball. Each object created in such a fashion looked the same when it comes to the material and color. But none have a different twist in its look and feel. The same applies to the arena of 3D graphics.

Authoritative Server - MMO

Latency, Authoritative Server, Lag Compensation, Course Correction, Packet Drops and Client Side Prediction. These are things you would worry about when attempting to build a MMO game. For companies where the delay matters these logics are a must. This post is on setting up an Authoritative Server. There are different ways of setting up the authoritative server. Some of them is mentioned here. You have N clients and one client acts as the authoritative server: Imagine N clients with different machine configurations. The server would need to decide the best possible machine and have the physics simulation run in that. We then have issues with client disconnecting in which case we need to swap the authoritative client to another machine. This means we have to maintain all the state the game was in and move it to the new authoritative client. In an online environment this is simple nothing but nonsense. There is a dedicated server which simulates everything including physics and ...

Code dependencies

Are you struggling to make a given set of scripts from a project compile error free? If that is true, then you are in the same boat as I am right now. I have come across projects where logic is scattered around to get a functionality out of the pipeline with limited value to object oriented programming, and the most valuable and time saving of all is the plugin architecture. This is as best as it can get. Let me explain.. A producer has an idea and wants to make a quick prototype. He opens a new project, drags and drops the packages he needs and boom the game runs. Obviously you don't expect a producer to code (unless he is from development). The game would not be perfect, but at least it would get the ball rolling and you don't need a developer to assist the producer. Now, to do this, you would want the packages to follow a common rule. You can do this using an interface and have classes implement them. For example, the avatar package and the pet package can implement the...
