Does Love 0.8.0 have any way of setting the volume for individual channels(i.e Left, right)?

[editline]9th July 2012[/editline]

Im trying to implement 2d sound with love(Ideally I would like to control individual channels) so far I have:
[lua]
function toRad(n)
return n * 0.0174532925
end

function love.load()
love.graphics.setBackgroundColor( 255, 255, 255, 255 )

image = love.graphics.newImage("Speaker.png")

music = love.audio.newSource("Reunited.mp3")
music:setLooping( true )
music:setDirection( 0, 1, 0 )
music:setPosition( 300, 300, 0 )
music:setDistance( 1, 200 )
music:play()
end

function love.update(dt)
x = love.mouse.getX() - 300
y = love.mouse.getY() - 300
love.audio.setPosition( x, y, 0 )
end

function love.draw()
love.graphics.draw( image, 300, 300, toRad(90), 1, 1, 16, 16, 0, 0 )
love.graphics.setColor(0, 0, 0, 255)
love.graphics.print("Song: Reunited by Incomptech.com", 5, 5)
love.graphics.print(music:getVolume(), 5, 50)
end[/lua]

But nothing happens, I think the problem is I dont know what the ref is meant to be in: Source:setDistance( ref, max )

Never used AS, but I found something that might help you. Apparently the Embed statement thingie creates a new class instead of an object instance, which you need to instantianate to get the actual resource.

For example
[csharp]
[Embed("../lib/NES_Pinball.org", mimeType="application/octet-stream")]
private static const PinballOrg:Class;

// Later
orgPlayer = new OrgPlayer(new PinballOrg());

// or if that doesn't work
var org:ByteArray = new PinballOrg() as ByteArray;
orgPlayer = new OrgPlayer(org);
[/csharp]

Same thing for LOGO I guess. Google "actionscript embed bytearray"

I have a pretty general question about cross-platform development that I can't seem to find any straight-forward answers on.

A 64bit Windows machine can run 32bit Window applications. Usually. This is nice and easy.

On Linux, from my understanding (and I'm looking for someone to tell me I'm correct or horribly wrong here), there are different distros and there are different architectures. Whether or not an application RUNS depends on if it was built for that architecture. Whether or not it installs as a package depends on if it was packaged for that distro. If I just gave someone an executable, they can run it so long as they have the correct architecture. Is this correct?

Should I target i386 for 32bit and x86_64 for 64bit?

Can someone explain to me how this works on a Mac?

[NovembrDobby]

[QUOTE=jalb;36700639]Should I target i386 for 32bit and x86_64 for 64bit?[/QUOTE]

Yes. Don't make the same mistake I did and assume some kind of backwards compatibility.

What Darkwater means is that the database is never exposed to the client, there's some kind of middleware application that talks to the client, checks the data and then runs database operations.

I don't think that's possible. What I do is I normally make an ASP.NET script that is fetching the data into an XML document (server-side) and then using a XML-parser in C# to retrieve the data. I think that's the safest way.

x86_64 Linux can run i386 programs, just like in Windows. The complication is that most programs depend on a few libraries, and 32-bit executables need 32-bit libraries, and a 64-bit system might not have 32-bit libraries installed.

64-bit Windows includes 32-bit versions of all the system libraries because backward-compatibility with 32-bit apps is essential there, but on Linux, programs are typically just recompiled as native 64-bit binaries, so the 32-bit compatibility is less essential. Any major distro should have some way to get 32-bit versions of the most common libraries installed, but they might not be there by default, and the packaging that makes them available tends to be klugey — i.e. the package claims to be built for 64-bit so that the package manager will be willing to install it, even though it contains 32-bit binaries and puts them in odd places to avoid conflicts with the real 64-bit versions.

You're better off building both 32-bit and 64-bit binaries, rather than building just a 32-bit binary and expecting 64-bit users to run it too.

[QUOTE=jalb;36700639]Should I target i386 for 32bit and x86_64 for 64bit?[/QUOTE]

If you're only talking about Intel/AMD-compatible processors, yes. But remember that there are other, unrelated architectures like like ARM (used by most mobile devices) and PPC (used by older Macs), which also have their own 32-bit and 64-bit flavors. If you want to support those architectures, you have to build separate binaries for them as well.

Sure.

[cpp]float cell[20][20];
memset( cells, 0, sizeof( cells ) );[/cpp]

[Wyzard]

That's much more efficient than my suggestion of a loop, but initializing things with memset() has always bothered me a little. It's making a non-portable assumption that a certain value of a certain data type is physically represented by a certain bit pattern in RAM. (Yes, setting to zero is valid for floats with IEEE754, but even IEEE754 isn't universal.)

However, krazipanda, why are you using floats when it sounds like the values will all be integers? If each distinct value has a specific meaning, I'd recommend using an enum as the type of your array.

I would like to make a textbox class for my XNA game. I am struggling on the "focus" aspect, so that when you type it knows which textbox to send the letters to.
In windows forms, if you have 2 text boxes, say, then click inside one, it will highlight/focus and you can type in it. Click on the other and the other will defocus, how does .NET do this object interaction? It doesn't store a list of text boxes, and there is no textbox manager or something to say which has focus and which does not.
Seemingly trivial question but I can't seem to find a neat solution, any ideas?

I'm trying to use stringstreams for getting ints into a string. I do it like this:

[cpp]
DilbertImage::DilbertImage(int d)
{
cal.setDate(d);

int year, month, date;

year = cal.getYear();
month = cal.getMonth();
date = cal.getNumDate();

std::stringstream ss;

ss << year << "/";

if(month < 10)
{
ss << 0;
}

ss << month << "/" << "Dilbert - " << cal.getNumDate() << ".gif";

filePath = ss.str();

ss.str("");
ss.clear();

ss << startUrl << date << endUrl;

url = ss.str();

std::cout << url << '\t' << filePath << std::endl;
}
[/cpp]

[cpp]
std::string const DilbertImage::startUrl = "http://tjanster.idg.se/dilbertimages/dil";
std::string const DilbertImage::endUrl = ".gif";
[/cpp]

I expect to get two nice strings that look like this:

url: http://tjanster.idg.se/dilbertimages/dil20060720.gif
filePath: /2006/07/Dilbert - 20060720.gif

But instead when I put the ints in the stringstream they somehow endup getting spaces (or some other blank character inserted in the middle of them)

They end up looking like this:

url: http://tjanster.idg.se/dilbertimages/dil20*060*720.gif 
filepath: /2*006/07/Dilbert - 20*060*720.gif

I've been trying to get this to work all night now, why is this happening :(
