requested_direction

)

Requests change of current snake direction in state machine.

Parameters

requested_direction

Direction requested by input system.

Note

Called by game.c state machine.

snake_fruit_check()

void snake_fruit_check

(

void

)

Here is the call graph for this function:

Here is the call graph for this function:

snake_get_state()

const snake_state * snake_get_state

(

void

)

Passes current snake game state.

Note

The pointer represents valid state until next snake_update() function use.

int

fruit_seed

)

Requests initialization of the snake game in state machine.

Parameters

fruit_seed

Seed used for random fruit position generator.

Note

Called by game.c state machine.

snake_is_over()

bool snake_is_over

(

void

)

Checks if snake game state is GAME_OVER.

snake_move()

void snake_move

(

snake_move_request()

void snake_move_request

(

void

)

Requests 1-tile move of snake in state machine.

Note

Called by game.c state machine.

snake_update()

void snake_update

(

void

)

snake logic state machine function.

Handles three snake game states (INIT, GAME_OVER, RUNNING).

Note

Called by game.c state machine.
