SKYRUNNER Skyrunner is a typical cosmic hero who is fighting his way through a planet flowing with lava and volcanoes and has the power to fly through the clouds. It has aliens which are land bound as well as sky bound. His goal is to not to die, collect coins for points and finish this level. This is a prototype presented here. Our group represented a virtual game company and was called ABSolute Game
Studios. The team members were:
As the Lead Programmer my responsibility was to develop a framework to combine different elements of a game:

Technical Details Finite State Machine FSM for characters and enemies have been designed separately as both have different states and behavior.
The FSM class is an abstract class containing all the states. Its for the client to use only those states necessary for their entity. enum mStates { mNew = 1, mHide, mMove, mIdle, mAttack, mDestroy, mJump, mTurn }; Entity Abstract Class This is the base class for all the characters and objects in the scene. It defines the type of object, inherits from Physics and FSM classes. The Physics class defines the types of geometries to be used. Due to troubles with handling Box geometries, we have used Ray geometries and the collision detection algorithms in Collision class, inherited from OPCODE. The update function has been introduced to update entities in the world. Every object like Hero, Enemies or Fireballs write their own update function, implementing the FSM states and changing the behavior and parameters of the object. Other functions to update the Entity class' parameters are already written. The client can override them with their own implementation. World Entities All the moving entities in the world are added through an EntityList. Entites can be pulled out through their names and inserted into the list. It is a structure storing entities via their names. This lets you recycle a few number of objects to display more objects in the scene. Entities in this game are:
OgreAL is the wrapper for integrating OpenAL with Ogre3D. It provides the Sound Manager which is used to add new sounds or delete sounds. Only one manager should exist in the whole program hence using the Singleton Pattern. This way it can be inherited by any object for attaching a particular sound to it or be used in the main program to add sounds depending on events generated. |
