Maze 3D

This is a simple maze game written in OpenGL. The objective of the game is to reach the end of the maze.

NOTE: This was done as a final project for the subject Computer Graphics. Some of the starter code was written by the professor, while the rest of it was written by me and my project partner.

Features

• Aim of our project was to create a 3-D maze, much like the old game Wolfenstein-3D (1992)
• Maze representation of walls
• Collision detection (Bounding-box)
• Sky-cube
• Smoothing movements
• Normals implementation on walls
• Lighting
• Animated finish point indicator

Keyboard/Mouse controls

• You can turn around horizontally using the mouse.
• w or ↑ - Move Forward
• s or ↓ - Move back
• a or ← - Move left
• d or → - Move right
• q - Look up
• e - Look down
• p - Peek view - Camera is hoisting above the maze. You can still turn around, but moving forward or backward is disabled.
• esc - Quit the game

External resources

• For Collision detection - https://learnopengl.com/In-Practice/2D-Game/Collisions/Collision-detection
  • Ended up doing bounded-box collision detection
• Adding a sky-box - https://learnopengl.com/Advanced-OpenGL/Cubemaps
  • The image resource for the Skycube image was picked from here - https://opengameart.org/content/cloudy-skyboxes
  • This was a pretty awesome effect!
• Syncing camera with mouse and keyboard movements - https://learnopengl.com/Getting-started/Camera
• Smoothing the camera movement - https://stackoverflow.com/a/44432317/1518924
  • When holding down on a key, SDL sends the key-down events with a bit of a delay between them. In that delay, there would be multiple render calls that happen. This is the reason why the camera movement seemed uneven.
  • The above link, was the starting point to find the solution, and helped put us in the right direction.
• Animating an object - https://learnopengl.com/Getting-started/Shaders
  • Although the above link changes the color dynamically, we used the same principle to animate objects.

TODO/Improvements

• Our maze is basically a static one. We had an intention of randomly generating a maze every time this program is run. We did not do it, primarily due to time constraints, and we wanted to work on more graphics-related aspects of the project.
• Add Sliding collision - Right now, when brushing against the wall, the camera stops. Using sliding collision would avoid that.
• Adding a sound whenever the camera moves (I want "Jump in the Fire" by Metallica)
