Pond tutor mistake

[Sergi Llobet]

Hello,

when solving pond tutor nr 9, you need to approach to target till arrive 50. The solution I think it is wrong, once you should swim if X>50 (while you are further than 50) and not X<50. But the player swims if you write  X<50. 

while (true) { if (getX() < 50) { swim(0); } else { stop(); cannon(0, 40); } }

May be I misunderstand something...

Thanks,

Sergi Llobet

Could you tell me more about the 'solution'?  Is that a third-party lesson plan or book or something?  Where does "X>50" come from?

The code you wrote is exactly correct.  You got it.

Hi Neil

The fact is that the right code should be while (true) { if (getX() > 50) { swim(0); } else { stop(); cannon(0, 40); } }, once the ship should swim if the distance is bigger than 50. I understand getX() is the distance between the two ships, so that, while the distance is bigger (>) than 50, ship should swim. The solution says to swim if the distance is lower than 50 (>50) that is what I do not understand.

Best regards

Hi again

My mistake. get (X) is position, not distance. 

Best regards,

Sergi
