Hey I got some quetions
Question 1:
I have a image that is in a picturebox which is called pictureBox1
I want to read monstersetbase.txt and add small ellipses to my image. The position of the ellipse comes from my monstersetbase.txt. The image is 256x256 and the coordinates is example 125x150.
I figured out a way to write a ellipse on the picturebox. It looks like this:
And on my form load:
Now my problem is that I cant seem to figure out how to read the txt file properly when I need all the data
If I use for example:
then im getting the error:
Index was outside the bounds of the array.
Any suggestions?
My monstersetbase.txt:
78 and 60 is the x and y coordinates in the text above.
Question 2:
After I insert the ellipse I want it to be "link" like when I click on it something happens
I also want to display a tooltil when I have the mouse over my ellipse is that possible?

C# Syntax (Toggle Plain Text)
public void pictureBox1_Paint(object sender, System.Windows.Forms.PaintEventArgs e) { System.Drawing.Graphics g = e.Graphics; g.DrawEllipse(System.Drawing.Pens.Red, 125, 150, 2, 2); }
And on my form load:
C# Syntax (Toggle Plain Text)
public void Form1_Load(object sender, EventArgs e) { pictureBox1.Paint += new PaintEventHandler(this.pictureBox1_Paint); this.Controls.Add(pictureBox1); }
Now my problem is that I cant seem to figure out how to read the txt file properly when I need all the data
If I use for example:
C# Syntax (Toggle Plain Text)
public void pictureBox1_Paint(object sender, System.Windows.Forms.PaintEventArgs e) { String line; String data; System.Drawing.Graphics g = e.Graphics; // Reading txt file from fileLocation using (StreamReader sr = new StreamReader(Convert.ToString(@fileLocation))) { while ((line = sr.ReadLine()) != null) { // Converting line to string from txt file data = Convert.ToString(line); // Splitting data into piecesMap[] String[] piecesMap = data.Split('\t'); // Converting x/y cord to float from string float xCord = float.Parse(piecesMap[3]); float yCord = float.Parse(piecesMap[4]); // Displaying ellipse g.DrawEllipse(System.Drawing.Pens.Red, xCord, yCord, 2, 2); } } }
then im getting the error:
Index was outside the bounds of the array.
Any suggestions?
My monstersetbase.txt:
C# Syntax (Toggle Plain Text)
3 0 0 30 78 60 240 240 -1 5 // Red Dragon 1 0 30 185 132 185 132 -1 10 // Golden Titan 2 0 30 183 128 188 135 -1 10 // Golden Solider 3 0 30 10 10 240 240 -1 12 // Golden Goblin 4 0 30 10 10 240 240 -1 8 // Golden Dragon 5 0 30 185 132 185 132 -1 7 // Golden Lizard King 6 0 30 132 83 132 83 -1 10 // Golden Vepar 7 0 30 183 128 188 135 -1 6 // Golden Tantalos 8 0 30 132 83 138 90 -1 10 // Golden Wheel end 1 9 33 10 85 162 95 168 -1 5 // Kundun Demon 10 29 30 40 113 45 116 -1 3 // Kundum Demon 11 41 5 126 160 125 161 -1 2 // Kundum Demon 12 38 5 106 161 111 160 -1 2 // Kundum Demon end
78 and 60 is the x and y coordinates in the text above.
