-- **`bot.shaded_food`** <a id="shaded-food"></a> a list of the food pellets currently in the shadow of one or both of the team's bots. When a bot is in its homezone it casts a shadow of **3** squares. Food pellets that happen to be in the shadow for **15** rounds without interruption will get relocated at the next turn. When a food pellet turns grey in the GUI it signals that there are just 3 rounds left before being relocated. The new position of the pellets is chosen randomly within the free squares of the bot homezone, but outside of the bot's shadow and not on top of another bot. Note that **`bot.enemy[0].shaded_food`** is always empty, i.e. you can not see which food pellets are in the shadow of the enemy.
