Description

The SnakeGrid class represents a grid specifically tailored for the Snake mini-game. It includes default dimensions and methods that assist with snake-specific functionality, such as detecting collisions and having grid positions for rendering.

Constructor

SnakeGrid()

• Description:
  • New instance of the SnakeGrid with default dimensions of 20x20 cells.

Methods

boolean isCollision(int x, int y)

• Parameters:
  • int x and int y: The x-coordinate/ y-coordinate of the cell to check.
• Returns:
  • boolean: true if the specified cell is occupied (indicating a potential collision), false otherwise.
• Description:
  • Checks whether a particular cell on the grid is occupied. This is primarily used to detect collisions with the snake's body or other obstacles.

Vector2 tileToWorldPosition(Vector2 gridPosition, int cellSize)

• Parameters:
  • Vector2 gridPosition: The position on the grid that needs to be converted to world coordinates.
  • int cellSize: The size of each cell in pixels.
• Returns:
  • Vector2: The corresponding world position for rendering.
• Description:
  • Calculate the offset to centre the grid and calculate the world position
