Question

I'm making a text-based game and I would like my hero to be able to move within a 3x3 grid. I tried doing this with a two-dimensional array fairly easily. The problem that I encountered was that I wanted to call a method for each grid the hero was in. So if the hero was in grid 0,0 then I would call the atHouse() method, if he went to 0,1 I call the atTree() method. Each of those methods would give a description of that area, items in it, etc...

So, since I wasn't able to store methods in an array I was thinking of possibly doing another way. I just don't know what way might be the best. Has anyone setup a world in a quality way that is better than what I described?

Answer 1

I would think an array of a base class, call it location with a describe() method would be the best way to do this. Then you can subclass a house class and a tree class.

Or you could just create instances of location and set a description property.

Answer 2

Rather than storing objects in an array you could define a method which would take position as param. Say position 1 means hero is in 0,0 and position 2 means hero is in 0,1. You could define a method as:

public void heroMoved(int position){
  switch(position){
    case 1:
           call method associated
           break;
    case 2:
           call method associated
           break;
        .
        .
        so on
}
}

Answer 3

The simplest solution is to create a factory method:

I'd suggest a 2d array with names for each position:

[
    ["House", "Tree", "etc"],
    ["etc", "etc", "etc"],
    ["etc", "etc", "etc"]
]

Then, you'd pass the position into your factory method which would grab the function name for to use in a switch. Obviously, this solution is not the best, as you'll have to explicitly define each method call.

public void runMethod(int row, int col)
{
    string mName = myArray[row][col];

    switch(mName)
    {
        case "House":
            atHouse();
        break;
        //etc
    }
}
