[QUOTE=Fetret;33528537]Can someone help me with getting sound amplitude (sound energy) with FMOD? Basically I am trying to do beat detection. I understand how beat detection works/should work, but I can't seem to get the amplitude from FMOD. I feel like I am missing a huge point. I know how to get and work on the spectrum data, but I can't figure out how to use that as an average and instant value to do comparisons and detect beats.[/QUOTE]
Take a few samples (at least a few wavelengths), square each sample and add them all together.

This is for energy, not amplitude. They are, in fact, different. For example, a square wave contains more energy than a sine wave with equal amplitude.

That returns void. I don't know how to create threads in C#, but in Java you create a new anonymous Thread class, like this:
[csharp]
Thread thread=new Thread(){
public void run(){

}
}
thread.start();

That would be calling the method. When constructing a delegate you are supposed to pass the method. Also you want to use 'ParameterizedThreadStart' instead because you are passing a parameter.

[csharp]
t[i] = new Thread(new ParameterizedThreadStart(ReceiveStart));
t[i].Start(port);

public void ReceiveStart(object obj)
{
int port = (int)obj;

According to that your program did not crash, but end with a return-code of 1.

Show us your main.

[ZeekyHBomb]

Could be an exit(1) or something from within the library (though that's probably a bad idea actually).
You could set a breakpoint after you create the shader program (or add more output to narrow it down) and step through each statement from there to see where precisely it stops executing.

Is it possible to change the backcolor of a windows form while the program is running?

[Blade]

[QUOTE=reevezy67;33546144]Is it possible to change the backcolor of a windows form while the program is running?[/QUOTE]

All the properties in the designer are actually a property in the class. So you can either do this.BackColor = color; if you are in the form class or you can do formobj.BackColor = color if you have a reference to the form.

hierarchical database structure.
That's just a way of using keys right?

I can do that in MySQL right? all in the same table?
Or is having 1 key point to another entry still a relational database?

If I can do so in MySQL would I have another table where parents store a list of their children in the same field? like so

parentID|childrenIDs
daddy001|daughter002,son003,bastard666

or would I do something like this

parentID|childrenID
daddy001|daughter002

[ZeekyHBomb]

Try setting a breakpoint at exit and _exit (b exit and b _exit). When it halts, do bt to see the call stack.
I'll be good to have a debug-build so the call stack is completely in tact.

[xxxkiller]

In SFML, when you want to draw something, you use the function app.Draw(something), where app is the name of whatever your RenderWindow is called.
I want to have a Class, that has a function, which draws itself. So if my Class is called "car", then I want to use the funtion Car.Draw(); to draw it.

I have tried this, but it does not work:

class Test
{
public:
		Test();
                ~Test();
	void Draw(sf::RenderWindow);
	void setColor(sf::Color, sf::Color);
	void setPosition(int, int);
	void setSize(int, int);
private:
	int xPosition;
	int yPosition;
	int height;
	int length;
	sf::Color backgroundColor;
	sf::Color foregroundColor;
};

void Test::Draw(sf::RenderWindow window)
{
	window.Draw(sf::Shape::Rectangle(100, 100, 200, 200, sf::Color(100, 100, 100)));
}

The Code does not do much yet. I want to get the drawing to work first of all.

Any help would be appreciated.

"window" in your Draw() function is a copy of the sf::RenderWindow you pass it, not the original sf::RenderWindow object. To fix that, simply pass a reference instead:
[cpp]void Test::Draw(sf::RenderWindow &window)[/cpp]

[editline]3rd December 2011[/editline]

Also, I'd recommend passing sf::RenderTarget instead of sf::RenderWindow, just means you can do stuff like Draw(someRenderImage) as well as Draw(myWindow).

[xxxkiller]

Thank you! It worked flawlessly on the first try!
May I ask what the difference between RenderWindow and RenderTarget is?

[backwardspy]

[QUOTE=xxxkiller;33550832]Thank you! It worked flawlessly on the first try!

Glad to hear you got it working!
RenderTarget serves as the base class for things like RenderWindow and RenderImage. It provides the .Draw() function which the aforementioned classes can override to perform more specific operations. For example, RenderWindow draws the given Drawable to its window context, while RenderImage draws it to a texture stored in memory.
The reason I recommend you use that is so that if you ever need to draw to something that isn't a window (like a texture), you can!

[xxxkiller]

Good to know. Thank you for the quick responses!

It can't find the image file is my guess. I haven't used SFML but looking at its docs it seems that LoadFromFile doesn't throw an exception if the file is not found, but rather it returns false if it fails. Check its return value.

It's returning true, that means it's loading. But I came back to the thread just now to post that I found out what was wrong.

Apparently, when you assign an sf::Image to a sf::Sprite, the Sprite doesn't actually contain the image, so it was just returning a blank image when I tried to draw it. To avoid that, I simply had to make the sf::Image a part of the Player class to avoid it from being deleted after the creation function was done.

Silly me :v:
