C# dice game (imagelist)

Jonathan Crispe

i don't know how to do this:
After the Roll button is pressed, a timer will be enabled to generate random die rolls every 1/10 of a second. The images shown for each die will change with the random numbers generated, so the dice will appear to be rolling randomly.After about 10 random rolls, the timer will be stopped and the final roll and current score displayed.

public partial class Form1 : Form
{
Random m_rnd = new Random();
List diceResults = new List();
List dice = new List();
int diceTotal;
private int[] i_Array = new int[5] { 0, 1, 2, 3, 4 };
public Form1()
{
InitializeComponent();

pictureBox1.Image = imageList1.Images[i_Array[0]];
pictureBox2.Image = imageList1.Images[i_Array[1]];
pictureBox3.Image = imageList1.Images[i_Array[2]];
pictureBox4.Image = imageList1.Images[i_Array[3]];
pictureBox5.Image = imageList1.Images[i_Array[4]];
dice.Add(pictureBox1);
dice.Add(pictureBox2);
dice.Add(pictureBox3);
dice.Add(pictureBox4);
dice.Add(pictureBox5);
}

private void btn_roll_Click(object sender, EventArgs e)
{
pictureBox1.Image = imageList1.Images[m_rnd.Next(0, 6)];
pictureBox2.Image = imageList1.Images[m_rnd.Next(0, 6)];
pictureBox3.Image = imageList1.Images[m_rnd.Next(0, 6)];
pictureBox4.Image = imageList1.Images[m_rnd.Next(0, 6)];
pictureBox5.Image = imageList1.Images[m_rnd.Next(0, 6)];
diceTotal = 0;
diceResults.Clear();
for (int i = 0; i <= 4; i++)
{
diceResults.Add(m_rnd.Next(1, 6));
int imageNumber = diceResults[i] - 1;
dice[i].Image = this.imageList1.Images[imageNumber];
diceTotal += diceResults[i];
}
lbl_totalscore.Text = diceTotal.ToString();

}

private void timer1_Tick(object sender, EventArgs e)
{

}

private void btn_playagain_Click(object sender, EventArgs e)
{
pictureBox1.Image = imageList1.Images[i_Array[0]];
pictureBox2.Image = imageList1.Images[i_Array[1]];
pictureBox3.Image = imageList1.Images[i_Array[2]];
pictureBox4.Image = imageList1.Images[i_Array[3]];
pictureBox5.Image = imageList1.Images[i_Array[4]];
lbl_totalscore.Text = "0";
lbl_rollscore.Text = "0";
}
}

Well, to start with you need a click eventhandler for the pictureboxes. The easiest way is to create a skeleton handler for the first one from the Properties Box and then link the rest of the pictureboxes to the same handler.

I'm also assuming that you have two imagelists, imageList1 with the dice images in green and imageList2 with the same images in red.

Finally, you need a bool array to record whether the background image of a particular picturebox is red or not.

The following code is again off the top of my head so watch out for bugs. Changes are highlighted:

Random m_rnd = new Random();
List diceResults = new List();
List die = new List();
PictureBox[] dice = null;
int i_diceTotal = 0;
//int totalScore = 0;
int[] i_Array = new int[5];
int rolls = 0;
int i_rolling = 0;
bool[] isRed = null;

public Form1()
{
InitializeComponent();
die.Add(pictureBox1);
die.Add(pictureBox2);
die.Add(pictureBox3);
die.Add(pictureBox4);
die.Add(pictureBox5);

dice = new PictureBox[5]
{
pictureBox1,
pictureBox2,
pictureBox3,
pictureBox4,
pictureBox5
};

isRed = new bool[5]; // all false by default

for (int i = 0; i < 5; i++)
{
dice[i].Image = imageList1.Images[i];
i_Array[i] = i;
}

lbl_totalscore.Text = "0";
lbl_rollscore.Text = "0";
timer1.Interval = 10;

}

private void Form1_Load(object sender, EventArgs e)
{

}

private void btn_Roll_Click(object sender, EventArgs e)
{

rolls++;
lbl_rollscore.Text = rolls.ToString();
if (rolls == 3)
{
btn_Roll.Enabled = false;
}
timer1.Start();

}

private void timer1_Tick(object sender, EventArgs e)
{
for (int i = 0; i < 5; i++)
{
if(isRed[i]) continue; // don't roll if red
i_Array[i] = m_rnd.Next(0, 6);
dice[i].Image = imageList1.Images[i_Array[i]];
}

i_rolling++;
if (i_rolling < 10) return;
timer1.Stop();
//int rollScore = 0;
i_diceTotal = 0;
diceResults.Clear();
for (int i = 0; i <= 4; i++)
{
if (isRed[i]) continue; // don't roll if red
diceResults.Add(m_rnd.Next(1, 6));
int imageNumber = diceResults[i] - 1;
die[i].Image = this.imageList1.Images[imageNumber];
i_diceTotal += diceResults[i];
}
lbl_totalscore.Text = i_diceTotal.ToString();

}

private void btn_playagain_Click(object sender, EventArgs e)
{
rolls = -1;
dice = new PictureBox[5]
{
pictureBox1,
pictureBox2,
pictureBox3,
pictureBox4,
pictureBox5
};
for (int i = 0; i < 5; i++)
{
dice[i].Image = imageList1.Images[i];
i_Array[i] = i;
}
rolls++;
btn_Roll.Enabled = true;
lbl_totalscore.Text = "0";
lbl_rollscore.Text = "0";
}

private void pictureBox1_Click(object sender, EventArgs e)
{
PictureBox pb = (PictureBox)sender;
int index = int.Parse(pb.Name.Substring(10)) - 1;
if (isRed[index])
{
dice[index].Image = imageList1.Images[index]; // green image
isRed[index] = false;
}
else
{
dice[index].Image = imageList2.Images[index]; // red image
isRed[index] = true;
}
}

Everything is working just fine, there is one left to do and I'm having a hard time doing this:
When a picturebox is clicked, the background color will be changed to red, indicating that that particular die will not be rolled. If the user clicks on a red die again, the color will return to green, indicating that that die will be rolled.

        Random m_rnd = new Random();
        List diceResults = new List();
        List die = new List();
        PictureBox[] dice = null;
        int i_diceTotal = 0;
        //int totalScore = 0;
        int[] i_Array = new int[5];
        int rolls = 0;

            dice = new PictureBox[5]
            {
                pictureBox1,
                pictureBox2,
                pictureBox3,
                pictureBox4,
                pictureBox5
            };
            for (int i = 0; i < 5; i++)
            {
                dice[i].Image = imageList1.Images[i];
                i_Array[i] = i;

                int imageNumber = diceResults[i] - 1;
                die[i].Image = this.imageList1.Images[imageNumber];
                i_diceTotal += diceResults[i];
            }

The following is off the top of my head and so may be full of bugs:

public partial class Form1 : Form
{
Random m_rnd = new Random();
List diceResults = new List();
PictureBox[] dice = null;
int totalScore = 0;

public Form1()
{
InitializeComponent();
dice = new PictureBox[5]
{
pictureBox1,
pictureBox2,
pictureBox3,
pictureBox4,
pictureBox5
};

for(int i = 0; i < 5; i++)
{
dice[i].Image = imageList.Images[i];
i_Array[i] = i;
}

btn_playagain.Enabled = false;
lbl_totalscore.Text = "0";
lbl_rollscore.Text = "0";
timer1.Interval = 100;
}

private void btn_roll_Click(object sender, EventArgs e)
{
btn_roll.Enabled = false;
timer1.Start();
}

private void timer1_Tick(object sender, EventArgs e)
{
for(int i = 0; i < 5; i++)
{
i_Array[i] = m_rnd.Next(0, 6);
dice[i].Image = imageList1.Images[i_Array[i]];
}

rolls++;
if (rolls < 10) return;

timer1.Stop();
int rollScore = 0;

for(int i = 0; i < 5; i++)
{
rollScore += i_Array[i] + 1;
}

diceResults.Add = rollScore;
lbl_rollscore.Text = rollScore.ToString();
totalScore += rollScore;
lbl_totalscore.Text = totalScore.ToString();
btn_playagain.Enabled = true;
}

private void btn_playagain_Click(object sender, EventArgs e)

timer1.Start();
}
}
