Problem EC (200pts): Debuffs

The staff will prioritize helping students with required questions. TAs will not offer helps for this question (but senior students may).

Implement two final thrower ants that do zero damage, but instead apply a temporary "status" on the action method of a Bee instance that they throw_at. This "status" lasts for a certain number of turns, after which it ceases to take effect.

We will be implementing two new ants that inherit from ThrowerAnt.

• SlowThrower throws sticky syrup at a bee, slowing it for 3 turns. When a bee is slowed, it can only move on turns when gamestate.time is even, and can do nothing otherwise. If a bee is hit by syrup while it is already slowed, it is slowed for an additional 3 turns.
• ScaryThrower intimidates a nearby bee, causing it to back away instead of advancing. (If the bee is already right next to the Hive and cannot go back further, it should not move. To check if a bee is next to the Hive, you might find the is_hive instance attribute of Places useful). Bees remain scared until they have tried to back away twice. Bees cannot try to back away if they are slowed and gamestate.time is odd. Once a bee has been scared once, it can't be scared ever again.

	Class	Food Cost	Health
	SlowThrower	4	1
	ScaryThrower	6	1

In order to complete the implementations of these two ants, you will need to set their class attributes appropriately and implement throw_at methods. To make bees move slower or scared, you can add custom attributes to Bee class and update Bee.action.

Extra Challenge!

Can you complete this problem without modifying any code outside the SlowThrower class? That means you may not modify the Bee.action method directly.

Hint 1: Functions are first-class members.

Hint 2: Assign target.action to a function that sometimes calls Bee.action. You can use an instance attribute to track how many more turns the bee will be slowed, and once the effect is over, Bee.action should be called every turn.

Before writing any code, unlock the tests to verify your understanding of the question:

$ python ok -q EC -u

Once you are done unlocking, begin implementing your solution. You can check your correctness with:

$ python ok -q EC

Make sure to test your code! Your code should be able to apply multiple statuses on a target; each new status applies to the current (possibly previously affected) action method of the bee.
