Game cell content

Variants

Empty

Unoccupied cell — safe to move into.

Food

Cell holds a food pellet — moving into it grows the snake and triggers a respawn of the food.

SnakeHead(usize)

Head of a snake. The usize payload is the snake id, i.e. the index into GameState::scores and GameState::active_agents.

SnakeBody(usize)

Body segment of a snake. The usize payload is the snake id, same indexing as Cell::SnakeHead.
