Baby steps- catching dreams

We should be working

I’ve been trying to get more sleep lately. This means that a significant portion of my ‘coding time’ has now been exchanged for ‘sleeping time.’ That, in turn, means much less progress with my latest coding project, the Pokemon Card Game.

The major goal of this project is to familiarize myself with vectors and how to manipulate them easily, moving items from one vector to another, deleting them, changing aspects of single vector objects, etc. So fa, this has been somewhat achieved. I have definitely become more familiar with the idea of the vector (it’s an array with more reasonable manipulations). The problem is, I still run into problems with these manipulations (unable to delete items from a vector, etc).

Image

I’m not sure this thing will work

Secondary goals involve:

1. Presenting a more civilized (although still ASCII) interface. I would love to leave ASCII and the terminal behind, but that has been a very elusive goal that I have no idea how to tackle.

2. Building in more realistic randomness into the play while also shepherding this randomness into better gameplay (attacks are randomized, but contain modifiers to make them more challenging)

3. Trying to keep my code simple and organized

 

Let’s be honest, #3 has been right out the window.

#2 is coming, and I think it should be more straight-forward than my other issues, but it’s still not implemented.

#1 is the only thing I worked on at all last night. Although I have good ideas about how I could make this much better, I’m not letting ‘the perfect’ get in the way of ‘the good’ just yet. Right now, this is about what the interface looks like:

Stuck in the mud

ImageIt’s not that I haven’t been trying to move forward with this program (the Pokemon thing), the problem is that I’ve gotten stuck in the mud. I don’t think the problem is really so huge, but that I’m having trouble figuring out what the problem actually is. There’s just not sufficient direction in my debugger to point me to the problem.

The Next Step: Turning a Clown Car into a Pokemon Battle

It’s my son who asked me to do this. He’s recently taken up Pokemon and has insisted that my wife and I both learn to play so that we can have Pokemon battles with him.

Image

Pika!

I thought: Ok, I have this Clown Car thing all worked out already. Maybe I can just transform it into  what he wants. The basic idea is to transform the clown car into a deck of Pokemon cards. The I also need to have two other decks – one for the player’s hand and one for the computer’s.  At the start of the game, we should have all the Pokemon in the main deck. I thought I would make this main deck viewable and then allow the player and then computer to draw cards, one at a time until they fill up their hands (in my first example, I top out the player and computer decks at two cards each.

What I need to do is be able to move the cards from one deck to another. Apparently, there is a move function for vectors, but I haven’t been able to make this work. However, it shouldn’t be too difficult to just copy a card object from one deck to another and then erase the first instance.

Nevertheless, I have not been able to make this work yet. Here’s the code that controls the player picking and the computer randomly taking cards:

 

 

void drawCards(vector<Pokemon> &draw, vector<Pokemon> &player, vector<Pokemon> &computer){

bool playerChoice = true;

int playerPick= NULL;

int compPick;

int number = 0;

   //start with outline

    printVectorContents2(draw);

    cout<<“**********”<<endl;

    cout<<“Player’s hand”<<endl;

    printVectorContents2(player);

    cout<<“**********”<<endl;

    cout<<“Computer’s hand”<<endl;

    printVectorContents2(computer);

    cout<<“**********”<<endl;

    cout<<“**********”<<endl;

 

while (number < 2) {             //this is copying the pokemon into the new vectors properly, but not erasing them

if (playerChoice == true) {

            cout<<“Player, please choose a Pokemon from the draw pile (enter ID number)”<<endl;

cin>>playerPick;

cout<<“You chose number “<<playerPick<<“, “<<draw[playerPick1].getName()<<endl;

            player[number] = draw[playerPick1];

            //draw.push_back(playerPick-1);

            draw.erase(draw.begin()-playerPick-1);

            //draw.pop_back();

            //move(draw.begin()+playerPick-1, draw.begin()+playerPick-1, player.begin()+number);

            playerChoice = false;

            }

else{

            compPick = rand()%draw.size()+1;

cout<<“Computer chose number “<<compPick<<“, “<<draw[compPick1].getName()<<endl;

           // move(draw.begin()+compPick-1, draw.begin()+compPick-1, computer.begin()+number);

            computer[number] = draw[compPick1];

            //draw.push_back(compPick-1);

            //draw.pop_back();

            draw.erase(draw.begin()-compPick-1);

            number++;

            playerChoice = true;

        }

    }

    //exits when number =3

    cout<<“Finished drawing cards.”<<endl;

    printVectorContents2(draw);

    cout<<“**********”<<endl;

    printVectorContents2(player);

    cout<<“**********”<<endl;

    printVectorContents2(computer);

    cout<<“**********”<<endl;

    cout<<“**********”<<endl;

The problem I’m seeing is that nothing is actually moving. output:

**************

IDNumber = 1, name = Pikachu

IDNumber = 2, name = Froky

IDNumber = 3, name = FurFrou

IDNumber = 4, name = Meowth

IDNumber = 5, name = BunnleBy

IDNumber = 6, name = BeeDrill

IDNumber = 7, name = Gloom

IDNumber = 8, name = Diglett

**********

Player’s hand

IDNumber = 0, name = 

IDNumber = 0, name = 

**********

Computer’s hand

IDNumber = 0, name = 

IDNumber = 0, name = 

**********

**********

Player, please choose a Pokemon from the draw pile (enter ID number)

1

You chose number 1, Pikachu

Computer chose number 6, Gloom

(lldb)

This means that we are getting through the first round of picks, but crashing before second round. Previously, I did have a second round operational, but the player and computer hands remained empty and the Pokemon who had been picked remaining in the drawPile. Perhaps it’s a problem with using pointers?

Wow, Finally smoothed out that clown problem

ImageThis version of the clown application uses a vector (clown car) to handle the objects (clowns).

Each clown has a Name, and ID number, hit points(hps), and three attacks. The way this program works is that it seeds the vector with the clown objects at the beginning (this was part of the vector handling problem), then allows them to fight it out in the clown car – every time a clown’s hps falls to zero, the clown is dead and if thrown from the car (i.e., they no longer populate the vector. This proceeds until only one clown remains. The last clown standing is declared the winner.

As the battle occurs, cout statements indicate who attacks whom and what damage is inflicted. (note: every attack is a ‘hit’). If a clown is killed, this is also announced and then the vector is printed out to show what clowns remain in the car.

I believe there are no bugs remaining in this program. When I was working on it, I included a large number of debugging statements. These have been removed for clarity in the final product. I also removed the dialog asking what clown to eject – and removed the function that handled that query.

Collaborative Coding

Bridging the chasm between sandbox problems and real collaborative project-based learning.

day 1… in like a lamb

I reserved this space in August and haven’t done anything with it because I didn’t want to dilute any readership that I had with my main blog, downhousesoftware.wordpress.com. Nevertheless, I keep thinking about launching it anyway to keep a record of the work I’ve been doing (that sounds like I’ve gotten a lot done, but it’s mostly just finding my bearings).

Right now I have a semester and change of C++ under my belt, with a lot of outside projects to boot and I’ve recently started up a coding club for the little town of Paola, where I live. Although we only have a few members, I’m happy it’s up and going and I think we can all learn a lot from it given some time and the right projects.

Given all that, let’s call today day 1.

Please let me know if you’re interested in learning some coding too and would like to join me in tackling some simple problems – I think it would be a great experience learning to share files online and see more than just what’s above the surface.
