Damn, I didn't have read that part! x-) OK, then. Even if your representation might overcomplicate the things a bit, imho. ;)

It might be redundant, given that the Description has:

• The green alien (7) at [0,8] at turn 0 ends up at [1,4] (white alien) and gets shot down by your cannon at turn 1. Therefore, the time of registering your first shot is at turn 0.

@Blind4Basics, changed You can fire only one shot at a time to You can fire up to one shot per turn. This sounds a bit clearer.

@ccnuts, sounds fair, though the example test(s) should make it clear.

Ah, that sounds better. What about, simply: you can shot only 1 time per turn? ;o

@Blind4Basics, I can see how it may sound strange and I considered adding something like You can charge up the next shot while firing the current shot, but I figured the test example already cleared that up.

This means that the white alien at turn 1 gets shot down. You can initiate a cannon shot at turn 0, but it won't hit a target until turn 1 due to a "charging up" delay.

Errr... Something sounds really weird, here. Reading that, I expect that the ship do the following (numbers are turns order):

1. fire
2. reload
3. fire
4. reload
5. ...

But in this case, you could never have aliens shot at several consecutive rounds. And moreovder, thats not what I implemented at all. I'd bet htat's a problem of me misunderstanding the sentence, but I don't see where. :o

@ccnuts1, if you can point out what part is misleading I can see about making a change to clarify.

@B4B: The 2nd image shows the positions of the alien ships after the first move, but before the first alien gets shot down. So, as soon as the white alien ship arrives at [1,4], it gets shot down by the blast that was initiated at turn 0.

@ccnuts:

So as you point out we are going to shot at turn 0 (killing alien with number -2) and then at turn 1 (killing white alien with number -7).

Which alien with -2 are you referring to? In the Desccription, under "Your Ship's Limitations", bullet point 2 states that:

Your pulse cannon has a time delay of 1 turn. After the delay, your cannon blasts the first target in its path.

This means that the white alien at turn 1 gets shot down. You can initiate a cannon shot at turn 0, but it won't hit a target until turn 1 due to a "charging up" delay.

"shot" doesn't always mean "killed" ;)

EDIT: wait...

EDIT²: ok, looks like there is effectively a problem: it actually state at the beginning of the turn 0 end the second image is still at turn 0 but before the ship firing. @ Doc: tell us if we're wrong?
