Also, I see about devices, but it gives me an error. If you know some DirectX, could you tell me? Do I need to make an Enum?

I keep seeing (or something close to it...):
public void InitalizeDevice()<br />
{<br />
keyb = new Device(SystemGuid.KeyBoard);<br />
^ gives me error<br />
}
keyb or whatever you want to call it is what Im asking about

Download the source code from the site. It is available, but keyb is a member variable of type Device.

Since we all know (well, most of you) that I'm trying to construct a game, there's a couple more things I would like to know.
A) How do I use more than one key at a time. I have a player moving, and then jumping, but then he stops moving to the side once you press the jump button. This code looks somewhat like below.
protected override ProcessCmdKey(stuff)<br />
{<br />
switch (keydata)<br />
{<br />
case Keys.Space: <br />
Jump();<br />
case Keys.Right:<br />
Move_Right();<br />
}<br />
}
B) How to rotate Recangle rect. Say rect is hooked up to a timer though.
Also, if anyone could provide some articles on game physics, I'd like that. Or just to explain it a little. No code necessary, but I just want to have an idea on it. My thought was that developers set up points with algorithms to have a point stay to a certain part of, say a cube, and assign weight and rotation so it just goes by the points. Confusig, duh. That's why I want to know. Thaks SO MUCH in advance.
P.S. I should be just about done with stupid questions!

Hi,
1.
my app gets KeyPress events for every (printable) key I press, even when another
printable key is down at the same time, so the sequence "Adown,Sdown,Sup,Aup" generates
both the A and the S KeyPress event.
Two ideas though:
- it may depend on the actual keyboard firmware; long time ago I had a KB that only
could handle a single key action at a time (i.e. one key down blocked everything else,
except of course for the modifier keys)
- "printable" keys tend to autorepeat (i.e. generate extra Down and Press events when you
keep them down), maybe that is confusing you.
2.
you can translate, rotate, scale anything you like WHILE painting it, by using the
appropriate Graphics methods in OnPaint, such as Graphics.RotateTransform()
and the general Graphics.Transform().
Warning: these transforms are cumulative, they modify everything that follows.

How does RotateTransform work? I put in a float and it appears nothing happened.

Oh, I got it. But another question. How do you set up a switch for variables?

switch (what goes here)<br />
{<br />
case x = 1:<br />
blah<br />
break;<br />
<br />
case x = 2:<br />
blah <br />
break;<br />
}
Also with bools and other numerical types, chars. Thanks.

Hi,
switch(numeric expression) {
case constant_value_1: statement1; break;
case constant_value_2: statement2; break;
case constant_value_3: statement3; break;
...
default: statement_default; break;
}
switch expects a variable or expression of integer numeric type, char or string;
each case just expects a single constant of the same type (no "x=").
This is something you should find yourself by reading an introductory book on the
language you use, as well as by reading the available documentation (MSDN).

DirectX has DirectInput, which I think works better for input in games. You can also use keydown and keyup to track which keys are down at once.

Usually for games i don't do any actions on the keypress event, instead i set a flag to say that a key is pressed, and then when the main logic loop runs through, it checks the flags and performs different actions based on whether or not a key is pressed.
for example:
bool key = false;
onKeyDown() {
key = true;
}
onKeyUp() {
key = false;
}
main()
{
if(key)
}

How would you know which key id down?

So how can you tell which key is down? I figured out the KeyDown / KeyUp, but I need to know KEYS now. Thanks so far, though.

Hi
I've just created a simple application loader which recognizes a certain attribute i created and then loads a static method Load()
this is used to load particular classes which have to run as the application starts.
the weird thing is that in one of the classes the static constructor is called twice:
first time - when the application loader calls it via reflection
second time - when another part of the application uses this class for the first time.
if anyone has a clue
thanks

This only happens with one of the classes?

Hi!
form1 has a function to draw a line.For example: public void draw();
I also have form2 with a button.
when i click this button, a line will be drawn on form1.
(in the function of button click event, i call draw like this:
form1 myform=new form1();
myform.draw();
)
but it doesn't work.
So what should i do?
Best Regards!
|

It works, you just don't see it. The line is drawn on form1 which is invisible as you haven't displayed it.
|
|
|
|
|
Form1 appears behide form2, when i click button, i choose form1 to watch but i did not see the line.
So how can i see the line on form1? (because your reply is i did not display form1)
Thanks for replying!
|
|
|
|
|
When you call form1 myform=new form1(); you are creating a new instance of Form1 and the line is drawn on the new instance.
|
|
|
|
|
oh! i got it.
Back to the first problem, how to draw line on form1 (first form1) from button of from2? and how to display new form1?
Thanks for replying!
|
|
|
|
|
In order to do that you should make draw method of class static. As for the second question you can call either Show or ShowDialog method on the new instance depending on whether you want it to be non-modal or modal. By the way, all drawing code should be placed in the Paint event of the form so that it gets drawn when the form is repainted
