What do you need help with? Version 5

[ief014]

Try an older version, like 2008? 2008 and 2010 don't have many differences, especially if you don't program in .NET

I know that this wasn't in response to my problem, but I think I'll try out VC++ 2008 as well; as far as I can tell, people rarely have issues with SFML with VC++ 2008. Is there really that much a difference between 2008 and 2010, anyways?

I'm trying to work out how to return to a previous camera-zoom level after a camera is moved closer to a player (for example when being moved in front of a wall between the player and the camera).

An example situation would be where a player turns their camera around, causing it to zoom in due to hitting a wall and move closer to the player. The player rotates the camera so there is no longer anything behind it.

How would I restore the camera to its original 'zoom amount'?

Either store two variables or use temporary assigned values.

In case of the wall, you'd trace a ray of DISTANCE from the focus to the camera (pov+cam normal*distance is the place of the cam, so, you'd trace a ray from pov to pov+cam_normal*distance, the place where you've hit something is the camera's position, once the camera rotates outta the wall, it should go back to pov+cam_normal*distance)

[Gmod4ever]

Figured out my issue.

Apparently I downloaded the wrong version of SFML. No idea what I did download, but it didn't have any .lib files - instead, they were all .a files, whatever those are. :v:

However, since I've already gone through and uninstall VC++ 2010, and installed VC++ 2008, I'm just going to stick with 2008. Are there any major things I'll be missing out on, doing so?

Running VCSExpress.exe(the application one) from the folder works for me. Does it start up a process or anything or just nothing at all?

I don't even know this time, this should be a 256x256 grid. Pretty sure this isn't 256x256.

Code where the vertex locations are generated.

	int i = 0;
	for(int x = 0; x < 256; x++)
	{
		for(int z = 0; z < 256; z++)	
		{
			vertexLoad[i].position = D3DXVECTOR3(x, 0, z);
			i++;			
		}	
	}

Z is Depth. Also has to be rendered in orthographic.

[QUOTE=Lord Ned;35801253]Z is Depth. Also has to be rendered in orthographic.[/QUOTE]

Why would it need to be rendered in orthographic? Its rendering fine, just the grid is not a perfect square like it should be.

I believe Lord Ned said that because Orthographic projection might provide a more accurate depiction of a simple 2D object in a 3D space. It might have to do with 2D objects not having depth and therefore being invisible if seen from anywhere directly facing the edges of the polygon in a 3D grid. Projection also removes possible perspective distortion from 3D renderings, IIRC.

I have the camera setup so I can move it around, it is definitely the mesh that is messed up.

Is this deprecated OGL?

Sorry, misread as you wanted it to show up as exactly 512x512 pixels. But either way when you initialize the vertexes you're saying D3DXVECTOR3(Left-Right, Top-Bottom, Far-Near) - So you're saying "go far into the screen" instead of "go up on the screen".

[Zethin]

For the Java Programmers:

		
if (e.getSource() == Calc.eqls) {
	curText = Calc.tf.getText();
	if(curText.contains("*")) {
		if(curText.contains("+")) {
			int add = curText.indexOf("+");
			Calc.tf.setText((curText.substring(add-1)+curText.substring(add+1)));
		}
		else if(curText.contains("-")) {
			int subtr = curText.indexOf("-");
			Calc.tf.setText((curText.substring(subtr-1)+curText.substring(subtr-1)));
		}
	}
	else if(curText.contains("+")) {
		int add = curText.indexOf("+");
		int result = Integer.parseInt(curText.substring(add-1)) + Integer.parseInt(curText.substring(add+1));
		String result2 = Integer.toString(result);
		Calc.tf.setText(result2);
	}
}

I'm receiving a number format exception at the below line. I'm trying to make it so that I can take the numbers preceding and succeeding the ' + ' operator, add them together, then reconvert them back to a string so I can output it to the textfield.

[b]int result = Integer.parseInt(curText.substring(add-1)) + Integer.parseInt(curText.substring(add+1));[/b]

Variables:

tf = JTextField
Calc = Main Class
Rest are self defined.

Also, debugging it reports that the local variables are unavailable (I'm unsure if this is just a repercussion of a number format exception?)

--

I managed to solve it. I'm not sure what was causing it but there were a couple of problems within each other causing the ultimate number format exception.

Redefined code:

if (e.getSource() == Calc.eqls) {
	curText = Calc.tf.getText();
	if(curText.contains("*")) {
		if(curText.contains("+")) {
			add = curText.indexOf("+");
			Calc.tf.setText((curText.substring(add-1)+curText.substring(add+1)));
		}
		else if(curText.contains("-")) {
			int subtr = curText.indexOf("-");
			Calc.tf.setText((curText.substring(subtr-1)+curText.substring(subtr-1)));
		}
	}
	else if(curText.contains("+")) {
		add = curText.indexOf("+");
		try{
                        resulta = Integer.parseInt(curText.substring(0, add));
		        resultb = Integer.parseInt(curText.substring(add+1, add+2));
			resultc = resulta + resultb;
			result2 = Integer.toString(resultc);
			Calc.tf.setText(result2);
			System.out.println(result + "\n" + result2 + "\n" + curText + "\n" + resulta + "\n" + resultb);
		}
		catch(NumberFormatException e3)
		{	
				System.out.println(result + "\n" + result2 + "\n" + curText + "\n" + resulta + "\n" + resultb);
		}
	}
}

yes. Non-deprecated OpenGL no longer supports the matrix stack (glPushMatrix()/glPopMatrix()), client states are replaced with vertex attribute arrays. You no longer need to use glEnable/glDisable for textures, and you need to use shaders. The only line there that's not deprecated is glDrawElements

If you can't find the method/constant here then it's deprecated: [url]http://www.opengl.org/sdk/docs/man3/[/url]

I realize that, the issue is that it isn't a 256 by 256 grid. The last coordinate could go into the fifth dimension for all I care, just as long as its 256x256.

Are you complaining about the shape of it? Or are you saying there should be 255x255 more squares? I don't get what you're getting at.

[QUOTE=JohnnyOnFlame;35799781]Either store two variables or use temporary assigned values.

In case of the wall, you'd trace a ray of DISTANCE from the focus to the camera (pov+cam normal*distance is the place of the cam, so, you'd trace a ray from pov to pov+cam_normal*distance, the place where you've hit something is the camera's position, once the camera rotates outta the wall, it should go back to pov+cam_normal*distance)[/QUOTE]

Thanks a lot, managed to get it working using this method.

You want to use [[NSBundle mainBundle] pathForResource] to get the path of the file.

It is currently rectangular. It should be square. On the Z axis it is shorter than it should be.

Put a breakpoint in your code, step through it, see where it places the coordinates.
