[QUOTE=NorthernGate;26063779]The problem is I have no idea how to go about clearing and loading the alpha buffer and then loading it with the light intensity. The article doesn't actually go about telling me how to do that. Where as Overv's method is pretty clear.[/QUOTE]

Clearing is glClear(GL_COLOR_BUFFER_BIT); or something in deprecated OGL I think.
As for loading the light intensity:
[quote=http://www.gamedev.net/reference/articles/article2032.asp]Next we need to load the lights intensity into the alpha buffer. This does not need any blending, but depth testing is enabled this time to allow lights to be restricted to illuminating only the objects beneath them. Again colour writing is left disabled since we are not ready to render any visible geometry yet. The following function is used to create the geometry for a single light:
[cpp]public void renderLightAlpha(float intensity, GLDrawable canvas)
{
assert (intensity > 0f && intensity <= 1f);

GL gl = canvas.getGL();
int numSubdivisions = 32;

gl.glBegin(GL.GL_TRIANGLE_FAN);
{
gl.glColor4f(0f, 0f, 0f, intensity);
gl.glVertex3f(center.x, center.y, depth);

// Set edge colour for rest of shape
gl.glColor4f(0f, 0f, 0f, 0f);

for (float angle=0; angle<=Math.PI*2; angle+=((Math.PI*2)/numSubdivisions) )
{
gl.glVertex3f( radius*(float)Math.cos(angle) + center.x,
radius*(float)Math.sin(angle) + center.y, depth);
}

gl.glVertex3f(center.x+radius, center.y, depth);
}
gl.glEnd();
}[/cpp][/quote]

What I'm confused on is that I was under the thought that doing glClear( GL_COLOR_BUFFER_BIT ); would clear the screen, and the void renderLightAlpha function just draws faded circles over an emptied screen.

What I thought I was supposed to be doing to was clearing a quad over the screen and then cutting the light geometry into that quad, the light geometry would be translucent showing the objects under the light. But I have no idea how to do that either.

glClear is deprecated? What?

[ZeekyHBomb]

Eh, I don't think so; it just came to mind because the site was writing deprecated OGL code... it was late D:

I'm pretty sure the faded circles are correct. Use this information as a mask.
Like the explanation said, you are not drawing geometry and overlaying light information (which is Overvs approach), but you are drawing light information, and use this as a mask + light information (if I understood right) to draw geometry.

[QUOTE=pikzen;26062459]For resizable array-like objects, you can use java.util.Vector[/QUOTE]
Use ArrayList, not Vector. Vector is an old Java 1.0 class that's inefficient because it's synchronized. ArrayList is part of the newer collections framework that was introduced in Java 1.2.

Nope, it's code for my Lua game framework. It's part of the following sample:

how do i do like i let the user put in 6 numbers and the program tells the defferance on the lowest and highest number ????

What is he referring to with pnode? I know It's pseudocode but It doesn't make too much sense to use pnode->child and then other times just child.

[yngndrw]

In Node:Insert(), pnode is just referring to the current node. Additionally width and height are referring to img.width and img.height respectively.

If anyone could assist me with [url]http://www.facepunch.com/threads/1026684-Steam-ID-Community-ID-Conversion[/url] I would be very grateful :)

[yngndrw]

Exactly which line does it hang on ?

Also does the OpenSteamWorks library not have custom ID to ID conversion ? (I don't know, not used OpenSteamWorks - Just a suggestion.)

[jimbodude]

I'm not entirely sure at which line exactly, but the XML section, ( 32-93 in [url]http://pastebin.com/gvJyQ6xs[/url] ) is what is causing the hang.

As far as I know, the OpenSteamWorks library doesn't have such support, but I'll take a look at it, thanks.

[yngndrw]

You can use the debugger to get the exact line it hangs on.

I just run your code and noticed a few problems:
1) Line 56 won't be run.
2) The entire try-catch block at lines 58 to 83 don't make sense - It parses textEnterComm.Text as an integer, yet that is a custom URL which is most likely to be text.

I tested it with my steam page and it got to line 52 without any issues and had the correct numerical Steam Community ID.

[jimbodude]

Hmm thanks. My button code is now:

I commented out the conversion to SteamID from community ID right now, just to see if the correct community ID was retrieved.
Whilst this runs, and does return something, the ID returned does not seem to relate to the custom URL.
I used my custom URL, cherry_jimbo, but it returned 76561197989243780, where it should have returned 76561198003472229

[yngndrw]

You should break out of the while loop after you find it, currently you are finding your ID then all of your friends' IDs.

[QUOTE=jimbodude;26080848]Hmm, sorry to sound dumb, but I thought I was already doing that... Care to show me a quick example of what you mean?[/QUOTE]

Your break statements apply to the switch statements, not the while loop. Use a couple if statements instead of the switch statements (best solution), or create a variable you can set to false to stop the loop.

int main ()
{
cout << "Hello World! ";
cout << "Good bye world!";
return 0;
