This snake game includes the following graphics features as explored in class:
We have implemented different lighting options. These include changing the position of the light, by pressing u, j, h, k, or by toggling the main scene light.
In this game, there are multiple textures being rendered. For example, the entire map that the snake moves on has a grass texture binded to it. Other textures include a stone texture for obstacles, money texture for coins, and water texture for ponds. All of these objects appear on the map, and can be interacted with.
The alpha blending feature is implemented in the game and can be observed when the snake interacts with a pond object. When the snake interacts with the pond, it becomes slightly transparent for one move iteration in whatever direction it's currently travelling in.
Ray casting is implemented in this game such that the user can use currency to select and delete stone obstacles througout the map. Deleting an object requires 5 currency and can be achieved by left-clicking on an obstacle.
There is a user interface rendered around the main game screen area. Using gluBitMapCharacter, we render a title with instructions, along with a section for currency and scores which are constantly changing as the game progresses. They are rendered in such a way that when the game map is rotated, using the arrow keys, their appearance is unaffected.
