This is a project for the subject Interfaces Inteligentes in Universidad de La Laguna made by:

The project is rushed because we were working on a tight time frame.

Game description

Game Overview:

• The main loop of the game consists of defeating waves of increasing number of enemies.
• The player initiates each wave by pressing a button when they are ready.
• Enemies spawn from special points called "spawners" and aim to destroy certain objects near the player's tower.

Player Abilities:

• The player has a pistol to shoot enemies.
• The player can also craft 4 different kinds of potions in between waves that can be shot with a hand cannon.

Player's Workspace (Tower):

• The tower provides a view of the entire game map.
• Features:
  • Potion table with inventory access.
  • Main table with a pistol and a potion-firing cannon.
  • Game control panel for wave management.
  • Movement control panel for changing movement types.
  • An exit button.

Resource Management:

• Materials for potions are obtained by defeating enemies.
• Each potion creation consumes 4 ingredients.
• The player can control the wave start so the crafting can be made in between waves.

Weapon Summoning:

• Two books on the main table summon gunpowder weapons:
  • Right book: Summons up to two pistols.
  • Left book: Summons a potion-firing cannon.

Enemy Behavior:

• Enemies emerge from black cylinders and target white cylinders.
• If an enemy destroys a white cylinder, it changes color and becomes another potential entry point.
• The player loses if all white cylinders are destroyed.

Player Movement Options:

• The game offers two movement modes to cater to player preferences:
  • Player-Action-Based Movement: In this mode, players use a controller for movement, with a constant speed to prevent motion sickness.
  • Teleportation-Based Movement: This mode allows players to teleport to different positions within the game world, eliminating gradual movement changes while standing still to reduce motion sickness.

Movement and Rotation:

• Regardless of the chosen mode, real-world movements translate into virtual world movement.
• Players have the option to rotate in increments of 45º or -45º using "snap-based" rotations, preventing continuous spinning and reducing the risk of motion sickness.

Game Controls:

• The game utilizes only two input actions:
  • Grip Button: This button allows players to pick up objects and throw them.
  • Trigger Button: Players can use the trigger button to shoot.

Notable Design Decisions for Virtual Reality:

• The game's environment is designed to minimize the need for sudden and urgent head-turning, ensuring players can comfortably view the entire game terrain.

• Despite the bigger terrain where the enemies are located, the game offers a limited player area, which can be navigated using various comfortable VR movement systems.

• Haptic feedback is integrated into actions like shooting, enhancing the overall sense of immersion for players.
