Who can explain "The captain can’t rotate the weapon aiming system.",please?

The captain can't rotate angle

Does it mean that the system can only shoot at targets both coordinates of which are integers on just one line?

What??Sorry, I can't see what you say.

"laser can shoot at targets both coordinates of which are integers"

Any target with both integer coordinates in new coordinate system can be destroyed.

Really? This ought to be one of the most confusing statements I've ever seen, if this is true...
"The captain can’t rotate the weapon aiming system."
How come I can be at point (0, 0) and shoot at (1, 0) and (0, 1) if I can't rotate the aiming system?

You are not in point (0,0) - you are in the space near the planet. :) And all the points including (0,0) are on the planet's surface.

Are you Sure? But I got Wrong Answer many times. If it is true, I think the second answer must be less than 0.5*sqrt(2). Am I right?

Then is it true that every two pads can both be destroyed if they are equal after the decimal point?

This is true, for example, for pads with positive coordinates. Pads (0.0, 0.3) and (0.0, -0.7) can both be destroyed too.

I see. Thanks :)
