Question

I'm having some problems with Problem Set 6; I can't seem to get my updatePositionAndClean method to work.

What I want to happen is the following:
* set new direction
* set new position
* convert new position co-ordinates into int
* i.e. 1.3234243, 6.3234234 --> 1, 6
* This represents the Tile position the robot is on
* Check against dirty tiles
*etc

TypeError: a float is required

Answer 2

TypeError: a float is required

You want an integer and Python wants a float. Give it a float and see what happens.

Yah, I played around with it for a while and managed to sort my problem. Off the top of my head I can't remember where I'd slipped up. I'll stick a link in to my solution later :)

Answer 4

If you're still interested, here's my files...
I re-wrote a section in ps6_visualise.py because I changed the input parameters of isTileCleaned() to take a Position, since my whole program is communicating with a Position class it made no sense to suddenly start handing around a set of ints...
