BattleSpheres is a 3D Sci-Fi Multiplayer First-Person-Shooter game made with Unity3D game engine and Unity's own multiplayer and networking interface uNet. Whether pit-up against your friends locally, or strangers over the network, each room of up to 6 Players battle against eachother in a Free-For-All style tournament!
This was a project idea that I had while building Alienz as I had originally imagined Alienz to also be a 3D first-person-shooter survival game. But as that idea transitioned to be tile-based instead, I had reserved the first-person-shooter for BattleSpheres.
BattleSpheres is a typical Sci-Fi shooter that emerses the player (Spherical Drone) in a "simulated" environment made to model the area of a more primative setting, in an attempts to train the drone. Of course this was only a story idea, but the concepts remain the same between other first-person-shooters.
The player models themselves do not exhibit any humanoid features that aid in movement, such as limbs or rigged bodies. Instead the player models are equipped with vertical and horiontal thrusters. Each player can observe their thruster usage through the Thruster Fuel Guage indicated by the blue vertical bar on the left side of the screen. This was accomplished through a PlayerUI element being updated at every frame based on the player's monitored thruster fuel, as well as a processed control that would apply either a vertical or horizontal Vector3 motion vector to the player's current position based on which input key was pressed.
All movement is monitored through the PlayerController.cs script which sits on the player as a component.
This game's shooting mechanism is accomplished through Raycasting which casts a ray from the "casters" position, that being the FirePoint sitting on the player's weapon under their WeaponHolder, in a straight line extending a specified range. If through that range the ray is interrupted by an object's Collider, information about the hit target can be recorded through a Raycast object. That information was used in the following way:
- The object's
transform.positionand an identityQuaternion rotationwas recorded to be able to spawn aParticle Systemhit effect at the location of the hit object - The object's Player component was fetched in order to access the target player's health and decrease it by a parameter set on the shooting player's weapon. This was done through the
GetComponent<Type>()module.
All player shooting activity and processing is done through the PlayerShoot.cs script which sits on the player as a component.
All player weapon activity is taken care of through the PlayerWeapon.cs and WeaponManager.cs scripts also on the player.
Around the map, as of right now, the only available consumable items to the player are weapon pickup items. These weapon pickup items are only Unity Prefab assets placed at different locations on the game map. When an item meets with a player's Collider then an OnTriggerEnter method is called, taking in the source (player) collider's as a parameter. From this, the player's WeaponManager component is retrieved to equip the weapon attached to the pickup prefab. When a player equips a weapon, the weapon is instantiated and placed as a child object under the player's WeaponHolder and enabled, while all other weapons currently active are disabled. Finally, a player attribute corresponding to that weapon is set, such that a player who currently has that weapon may not be able to pick it up again once it respawns. All weapon pickup item events are handled through the WeaponPickup.cs script component on the WeaponPickup prefab.
The player starts off spawned in at one of the 3 spawn points managed by the NetworkManager as NetworkPosition prefabs equipped with a Sci-Fi Automatic weapon and 20 rounds of ammunition. As of right now each player starts off with 100 health, but ideas are currently being implemented to later support player power-ups that may affect this.
Before the game can be played, and a room joined, the player must login to his/her account through the Login Scene which is a GUI that interfaces with the Database Control module
- Each player is tied to a Player account associated through Username and Password handled through the Database Control
- The Database Control provides user account registration support, and error checking. This database is in no way secure, it was implemented for the purpose of practice
- Player Stats including the player's current Kill and Death records are displayed in the Lobby scene, and updated as the game progresses. Current game stats and progress can be checked through the Scoreboard in game.
Upon a player death, a death animation Particle System is instantiated and destroyed at the player's current location. Upon respawn, a spawn location is retrieved from a NetworkPosition component on the Spawn Point prefab and a respawn animation is instantiated. All player initial setup is handled through the PlayerSetup.cs script components on the player.
- Use the
W,A,S,Dkeys to move - Press(AND HOLD) the
Spacebarto take flight using thrusters! Hovering expends Thruster Fuel indicated by the blue guage to the left - Upon weapon pickup, a notification will be made at the top right-hand corner of the screen indicating this. A player may change their current weapon with the
Number Keysor theMouse ScrollWheel - A player may aim down sights with their weapon using
Right Click. The only weapon currently capable of this functionality is the Sniper rifle. - A player may view the current status of the game and Scoreboard using the
Tabkey - A player may navigate to their Pause Screen using the
Esckey
