What are you working on? :D

New post cuz this is a bit big. Taken from the top link in my previous post, second page of comments. Replace the Start() function in GlobalHook with this Start() function. Also, remember I know NO C#.

Class GlobalHook
 
public void Start()
{
      if (!_isStarted && _hookType != 0)
            {
 
                // Make sure we keep a reference to this delegate!
                // If not, GC randomly collects it, and a NullReference exception is thrown
                _hookCallback = new HookProc(HookCallbackProcedure);
 
                _handleToHook = SetWindowsHookEx(
                    _hookType,
                    _hookCallback,
                    System.Diagnostics.Process.GetCurrentProcess().MainModule.BaseAddress,
                    0);
 
                // Were we able to sucessfully start hook?
                if (_handleToHook != 0)
                {
                    _isStarted = true;
                }
 
            }
}

So, I have another question(regarding C#) and that is:

How do I reset my screen, or remove all of the drawings I've done? I've treid to clear all the graphics and redraw the background, but it only gives flickering... So any idea?

[kmercy]

Graphics.Clear();

should clear them all then you redraw after presuming thats how you are doing it but i would need to see the code to see how you are drawing them

[Aino]

No, you need a color, and setting it no color makes it black x.x

Also the flickering that's made by setting the background also makes it impossible to see anything...

[kmercy]

that makes no sense you since thats what you asked how to get rid of the drawings so you will need to post the code

[Aino]

Here:

Code: [Select]

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Collections;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {

        public double Zoom = 4;
        public double CameraX = 0;
        public double CameraY = -100;
        public int XPos = 100;
        public int YPos = 100;
        public bool[] MDown;
        public int MouseClicks = 0;

        public Form1()
        {
            InitializeComponent();
        }

        public void Render()
        {

            Graphics g = Panel.CreateGraphics();

            g.DrawImage(Bitmap.FromFile("C:\\Users\\User\\Desktop\\C# Examples\\Test2\\WindowsFormsApplication1\\WindowsFormsApplication1\\Picture.png"), Convert.ToInt32(CameraX) + XPos, Convert.ToInt32(CameraY) + YPos, Convert.ToInt32(400 * Zoom), Convert.ToInt32(400 * Zoom));

        }

        private void Timer_Tick(object sender, EventArgs e)
        {
            Render();
        }


        protected override void OnMouseDown(MouseEventArgs e)
        {
            switch (e.Button)
            {
                case (MouseButtons.Left):
                    MDown[0] = true;
                    break;
                case (MouseButtons.Middle):
                    MDown[1] = true;
                    break;
                case (MouseButtons.Right):
                    MDown[2] = true;
                    break;
                case (MouseButtons.XButton1):
                    MDown[3] = true;
                    break;
                case (MouseButtons.XButton2):
                    MDown[4] = true;
                    break;
            }
            MouseClicks = e.Clicks;
        }

        private void Panel_Scroll(object sender, ScrollEventArgs e)
        {
            if (e.NewValue != 0)
            {

                Zoom = Zoom * (1 + (e.NewValue / (720*Zoom)));

            }
        }
    }
}
Have been focusing on other things since all the comments, I'll begin making progress soon hopelyfully

But I don't understand why the scrolling isn't working, the mouse clicking is fine though

Ok, I've been going to java again, I know it very well too! But theres that one problem I face always!

You want to have classes to separate things easier and stuff, you don't use Arrays, like I did on Eufloria! So when it comes to check something with all the units from one class, you need an array to span over all of them to be able to select them. But I get a crash whenever doing that!

So, any idea of how to be able to select all of the different units from one class without any problems?

Thirteen and a half years old, but might be of use.

So this will leave me with something like this:

Code: [Select]


NumThings = 0
Text = {}

for i = 1,math.random(1,1000) do

NumThings = NumThings + 1
Text[i] = math.random(1,100)

end

for i = 1,NumThings do

print(Text[NumThings])

end

Considerd a basic example

I believe I'll create a new map soon, It's gonna be weirder than weirdest!

An, what I meant was(in the previous posts): to run through the objects from a class, like say it's three objects from the same class:

Name: Betty
Income: 300$ daily
Taxes: 50
Children: 0

Name: Chuck Testa
Income: 999999999$ daily
Taxes: 0
Children: 35557968 dead animals

Name: Alex
Income: 750$ daily
Taxes: 100
Children: 2

Now each have their individual name, income, taxe and amount of children. But they all come from the same class... This is called polymorphism!

What I looked for was how do I check a field/run a method from every single object from the same class?

And whis is polymorphism, what you guys told about polymorphism is overloading methods
I also hope this is useful for newbies, polymorphism is a simple thing, but very hard to learn...

Hum...Nope...That's just regular objected-oriented programming...

Store all objects created in a array, and loop through it....

[Aino]

I knew it was called Object-orienting, but it's also called Polymorphism(atleast what I've learnt...).

[Pilchard123]

*bzzzzt*

Nope, it's not.

[Aino]

Well, Polymorphism is several things, and Object-orienting is one, Method/Function overloading is another(why call any of this polymorphism when they have indivdual names too?) and another thing. Read http://en.wikipedia.org/wiki/Polymorphism_%28computer_science%29!

So, Polymorphism is both overloading methods and functionad and object-orienting! Do we agree now?

[Orion63]

You know, you're quoting an article that gives us reason, right?

Is Subtype Polymorphism, what you're confusing by Object Oriented programming?

An example of subtype polymorphism, the good old shape example(I have a Pascal(aka old) programming book with that example ^^)
Language is Python, because it's the closest thing to pseudo-code...

Code: [Select]

Class Shape(object):
    def getArea(self):
        pass

class Square(Shape):
    def getArea(self):
        return self.side ** 2)

class Circle(Shape):
    def getArea(self):
        return math.pi *self.radius ** 2

Since any shape can have his area measured, it makes sense, that the Shape class has a getArea method. But you can't determine the area of any random shape, by the same method, so you use different methods, with the same goal...
