Functions

• get_arena_height
  Get the height of the arena. This is constant and does not change during a game.
• get_arena_size
  Get the (width, height) of the arena. This is constant and does not change during a game.
• get_arena_width
  Get the width of the arena. This is constant and does not change during a game.
• get_cpu_cycles_per_tick
  Get the number of CPU cycles executed per tick. This is constant.
• get_current_cpu_cycle_in_tick
  Get the number of CPU cycles that have already executed in the current tick.
• get_current_pos
  Get the current position of the head of the snake.
• get_current_tick
  Get the current tick. Starts at 0.
• get_health
  Get the current health of the snake. The maximum health is 100. The health decreases by 1 each tick. If the health of a snake ever reaches zero, it will die. A snake can gain health by eating food. Food increases health. Poison damages health.
• get_id
  Get the id of the snake. This is constant, except after a split, where the new snake will have a new id.
• get_length
  Get the length of the snake.
• get_team_id
  Get the id of your team. This is constant.
• leap
  A leap is an additional move that can occur at most once every 2 ticks. It must only be called during a tick in which a move has already been performed, and a leap was not performed during the current or previous tick. Performing a leap will consume the last body part of this snake, which will drop on the floor as poison.
• move_snake
  Move immediately in the current direction. A snake must move once per tick. If the snake isn’t manually moved, it will be automatically called at the end of the tick. Note that this takes effect on the exact CPU cycle it is called. This means that all snakes do not necessarily move at the same time (you can pick when during the tick the move occurs).
• observe
  View a certain position in the arena.
• rand
  Get a random value between the min (inclusive) and max (exclusive). The returned value is deterministic based on the current state of the game and the initial seed.
• set_direction
  Sets the direction of the snake. This is the direction the snake will move next.
• sleep
  Sleep (do nothing) for a specific number of cycles.
• sleep_remaining_tick
  Sleep (do nothing) for all remaining CPU cycles in the current tick.
• speak
  Logs a message. The maximum length is 50. Any message longer than this will be truncated. A snake can send at most 10 logs per tick. Any additional logs will be ignored.
• split
  If the snake has a length of at least 9, it is eligible to split into two. The snake is split into three parts (the middle is rounded up, the rest down). The first part will remain as the original snake. The middle part will be lost and turn into poison. The end will become a new snake. The snake runtime will be forked, and both new snakes will continue to run independently. You can use get_id to determine which snake is now running.
• suicide
  Kill the snake immediately. All parts of the snake will turn into poison.
