Oakmar

About:

Oakmar is a 3D mobile adventure game made with Unity. You must control Oakmar, a small acorn, to complete puzzles and avoid obstacles to reach a glowing treesap, which completes the level. Each level has a couple collectables the player can obtain to unlock other areas of the game. After each level, the player is taken to a 3D level select where they can move around to choose a level to play (similar to Super Mario World). There are 15 levels, 10+ minigames, and a final boss.

Features:

Puzzle Plants

Within each level, there are "Puzzle Plants" which can be interacted with to start a minigame. These minigames range from mini-golf to matching shapes. Each puzzle plant uses abstraction for its class because the player begins and ends the interaction the same.

Highlights:

• Wide variety of minigames (minigolf, match the shapes, painting, etc.)
• Abstraction in classes to reduce unnecessary implementation

World Space Triplanar Shaders

Nearly all the terrain in the game uses a world space triplanar shader to render its material. This shader uses the XYZ axis and object's world space position, instead of UV's, to texture the object. This gives a consistent texuture size to all the terrain, regardless of how big or small its UVs are. In addition, the shader seamelessly connects textures across different meshes because it uses the world space position for its UV's.

Level Select

Oakmar features a 3D level select where the player moves across nodes that represent the levels. When standing on a level node, details for the level, like the name and collectables, are revealed. After completing a level, a path to a new level is revealed and some decor appears around the completed level node. Certain areas of the map are locked and can be unlocked using key items from a shop.

Inventory System

While in the level select, the player can access their inventory which displays their gems and key items. A JSON file is used to keep track of which items the players have as well as level specific data. The main currency of the game, silver coins, can also be displayed in the inventory. While in the game's shop, the three key items can be purchased. The gems however, must be obtained in specific levels. The key items and gems unlock areas of the game such as the final boss.

Boss Battle

The final level of the game (excluding bonus level) contains a boss battle against a wizard! In this battle the player must avoid three waves of attacks: fireballs, crystal walls, and dash attacks. After avoiding these attacks, a wall connected to chains will be lowered, which contains a few puzzle plants. Completing these puzzle plants will reveal another plant that can be used to attack the wizard. The cycle repeats until the player has destroyed the wizard!
