@TimmyD lol

If I had to guess, I think the -match operator barfed

@NathanMerrill Just throwing out bad ideas here in case a good one can be derived from it: don't allow them to index into the map. Create a getCell(x,y) method that returns a generic Cell object. The Cell object is a ReadonlyCell if you don't own the territory. Otherwise the Cell is an OwnedCell. Leave it to the caller to figure out which type to cast it to.

Nathan Merrill

well, ownership is by territories (collection of cells), and usually bots will want to do something on each of the territories

so I think I'm going to pass a list of territories

however, the problem is still there for certain cases

for example, a Territory has a "addObject" function

where an object can be a unit, tower, or a variety of other things

the only thing they can add is a unit or tower

(but internally, adding other objects can be added)

actually, I think addUnit() and addTower() are fine function calls

Nathan Merrill

7:16 PM

@Rainbolt bah, nevermind. "Package" literally means in the same folder.

it means that all of my objects would need to be in the same folder

TheNumberOne

@NathanMerrill Use a final protected method of the player to change the cells would maybe work.

Then have the superclass check to see if you can access that cell, and then call the package private method on the cell.

Nathan Merrill

package private doesn't work

because it requires everything to be in the same folder

and I'm not going to do that

TheNumberOne

You would need only your player abstract class and your cell class in the same folder.

Nathan Merrill

? Those are completely unrelated

I'd also need my Territory and my MapObject in the same folder

TheNumberOne

Alternatively, have the player pass themselves to the cell.

Or just some form of id that can't be duplicated.

@Dennis - beautiful work. Or 0.5 is inspired.

Nathan Merrill

@TheNumberOne MapObjects can add "cost" to a territory. Aka, a Territory has an addCost(int amount). I could require the MapObject to be passed in as well, but then I have to iterate through each of locations and check to make sure that the map object is actually there

there is definitely a tradeoff between "security" and "speed" :/

anyways, I think I agree with you guys...I should make unavailable functions inaccessible

I just don't like paying the costs

feersum

Does a "map object" represent the whole map, or some "thing" in the map?

Q: Mine Sweeper At Work

Everyone knows the old minesweeper game that shipped with Windows XP. It's a simple grid with a 9x9 matrix of cells containing either a number (indicating how many mines are adjacent to it) or a mine. The challenge is to generate a random 9x9 grid with 10 bombs given any integer seed (up to wh...

Idea for challenges with very much rules: a summary beside the real rules.

Nathan Merrill

8:18 PM

actually, most of my rules aren't that important to read

but because challenges need to be self contained, I need to explain the entire game, including all edge cases
