I caught you obviously :D :D I think the dummies books should be available in norway too.Quote:

I have added a cs file now for you in the post (#43 )before
Yeah, you caught me ^^'
but i am facing another problem (shocking)
I am trying to make a game for the first time. The history and gameplay is new and shocking:
Once upon a time, there were a platform. Upon this platform was a beautiful rectangle named sorus. The gameplay is moving this triangle around on the "platform" (Xtreme, huh?) :P
with other words, i have a rectangle with integers as location points. My problem is to make the rectangle able to use these integers. Where ever i put these integers, there is allways errors in the compiler. The most common one is "the name 'h' does not existist in the current context". I have put the integers in public classes, public voids, current and static classes etc. But the rectangle never accepts it anyway. Know why?
(dont mind the lack of namespace)Code:using System;
using System.Drawing;
using System.Windows.Forms;
public class resources
{
public void res()
{
int ah = 20;
int aw = 20;
}
}
public class game: Form
{
static void Main()
{
Application.Run(new game());
}
game()
{
this.Text = "Game1";
this.Size = new Size(300, 300);
this.Paint += new PaintEventHandler(paint);
}
static void paint(object objSender, PaintEventArgs pea)
{
int h = ah;
int w = aw;
Graphics grfx = pea.Graphics;
grfx.DrawRectangle(Pens.Black, h, w, 50, 50);
}
}
well, you've actually posted the wrong error..
you said 'h' doesnt exist in it's current context, which made me want to compile it because that cant be true. and like i thought, it wasn't true, the real error is 'ah' and 'aw' don't exist in the current context, which.. they dont.
ah and aw are declared in a different class that the game class has no idea about.
btw, if you were curious
Code:
using System;
using System.Drawing;
using System.Windows.Forms;
public class resources
{
private int ah;
private int aw;
public int AH
{
get
{
return ah;
}
set
{
ah = value;
}
}
public int AW
{
get
{
return aw;
}
set
{
aw = value;
}
}
}
public class game : Form
{
static void Main()
{
Application.Run(new game());
}
game()
{
this.Text = "Game1";
this.Size = new Size(300, 300);
this.Paint += new PaintEventHandler(paint);
}
static void paint(object objSender, PaintEventArgs pea)
{
resources res = new resources();
res.AH = 20;
res.AW = 20;
Graphics grfx = pea.Graphics;
grfx.DrawRectangle(Pens.Black, res.AH, res.AW, 50, 50);
}
}
Dude, i said i had all kinds of errors. That was just one of them. And thanks for the correction, but before i use it, is it any way i could press left, right, up and down to add and subtract from the location values without declaring any integers. yust go right into the rectangle and push the numbers up in any wayQuote:

oh, ok. Thanks for showing me how to do it. I have never seen that way before, so i dont totally understand it... I'll post up if i have problems :D
uh... how do i use the KeyPressEvent? i have the event, but i dont know what to do to make anything happen if i click DOWN or something like that
The first thing that entered my mind, was:
but that obviously doesn't work. How do i get my program to know if i've pressed a button!?Code:static void keyboard(object objSender, KeyPressEventArgs aep)
{
Keys test = new Keys();
if(test == Keys.Enter)
{
Form pop = new Form();
pop.Text = "bob";
pop.Show();
}
}
:(
Come on ... Its really time now. Go read a book, clear up, all the words you dont understand and read it from the first page to the last one. As you said you have Petzolds book. Take the examples there and you will see what you are asking for. But the truth is, you are riding the horse from the back. Why you dont start to learn programming trying to write code for Gothic 3 graphics part ?? hm ? :rolleyes: Oh godness :D my dear.Quote:

Believe me - this is the way down the learning curve, instead of upwards. You got more and ore which you cannot understand and at least you will loose fun on programming. Thats the end of the cycle then.
Even I showed you the correct code you still are using main() within a class which is derived from a form. I explained you, why you should not do that and showed you the correct way, I tried to learn you using namespaces but you are ignoring all that.. lets do some other things..
thats not the way to learn it - even when you are 15
And how in the world do you think your Keypress will get into your test Object ? By magic ?? The KeyPressEventArgs which you named aep you havn't used in any line. Why you use the delegate as a static one ? I cannot see to which control you add this delegate ? So if it is not added how should it be called .... Do you think programming works because you are using words like keyboard as the name of your delegate ?Quote:

And you said that i dont understand the codes the wizard makes for me, which is not true. And you allso said that i copy and paste code i dont understand, which isnt true eighter.:D
What i wondered about was how i can get the keypress into my program, and how do i use it? :D
Wrong it segments names to avoid clashes, you never know where code is going to run into this problem, plan for it from the very beginning.Quote:

By putting it in a separate file, obviouslyQuote:

Have you read HOW to use Viusual Studio???Quote:
so that has no use eighter. :P
The sentance makes no sense. If you Execute KeyPressed and a key is pressed (while your program has focus), then it returns true, else false...Quote:
Now all i asked was how i can get the keypress into my program,
Have you taken the time to read the documentation. If so, what exact sentance(s) did you not understand. Post the url, and the part you did not understand....Quote:
and how do i use it? :D
what documentation...
Start here:Quote:
