[RELEASE] My Boredom Shows! Look!

Hey guys I figured that it was time to help the MPGH community as I have taken so much from you guys...

So here we go. How to make a simple Metronome that keeps perfect time:

So now we must start by making a VC++ project. I use VC++ Express Edition 2008. Dev-C++ will not work for this tutorial.

So first what you are going to want to do after you have made the VC++ Console application project, is to get a short beep or tick .wav file. I have a little blub thing available to download.

Now in the solution manager create a new header file. We will name this file Includes.h

In the header file type this:

[PHP]
#pragma once;
#define VK_A 0x41
#define VK_B 0x42
#define VK_C 0x43
#define VK_D 0x44
#define VK_E 0x45
#define VK_F 0x46
#define VK_G 0x47
#define VK_H 0x48
#define VK_I 0x49
#define VK_J 0x4A//Theses define the alphabet Keys
#define VK_K 0x4B
#define VK_L 0x4C
#define VK_M 0x4D
#define VK_N 0x4E
#define VK_O 0x4F
#define VK_P 0x50
#define VK_Q 0x51
#define VK_R 0x52
#define VK_S 0x53
#define VK_T 0x54
#define VK_U 0x55
#define VK_V 0x56
#define VK_W 0x57
#define VK_X 0x58
#define VK_Y 0x59
#define VK_Z 0x5A
#define VK_PLUS 0x6B
#define VK_MINUS 0x6D
#include <iostream>//Used for console commands such as cout, cin, etc..
#include <windows.h>//Use this file to include hotkeys in the metronome
#include "TellTime.h" //Another header we will make.
#include <mmsystem.h>//Allows output of sound
#pragma comment(lib, "winmm.lib")//Link mmsystem.h to winmm.lib
using namespace std;
[/PHP]

Phew. That was a LOT of work. Now lets start on "TellTime.h" the most important piece of our code. When we are done with this, I'll break it down for you:

[PHP]
#pragma once;//So that this file is not included more than once.
using namespace std;//To use console commands
#include "Includers.h"//Includes the file we just made
int TellTime(int bpm)
{
cout << "Hit home to pause and change BPM. Hit home again to continue. For a BPM check hit home.\n";
int ticks;
while(1){
ticks = 60000/bpm;
PlaySound(L"tick.wav", NULL, SND_ASYNC | SND_FILENAME);
Sleep(ticks);
if(GetAsyncKeyState(VK_DELETE))break;
if(GetAsyncKeyState(VK_HOME)){
cout << "Your current BPM is: " << bpm << endl;
cout << "Plus & Minus changes it \n";
while(1){
if(GetAsyncKeyState(VK_PLUS)){bpm++;if(bpm % 5 == 0){cout << bpm << endl;}}
if(GetAsyncKeyState(VK_MINUS)){bpm--;if(bpm % 5 == 0){cout << bpm << endl;}}
Sleep(100);
if(GetAsyncKeyState(VK_HOME)){
cout << "New BPM is: " << bpm << endl;
system("PAUSE");
break;
}
}
}
}
return 0;
}



int GetBpm()
{
int bpm = 60;
cout << "How many BPM? Hit plus to increase, and minus to decrease. \nStarts at 60 BPM\nHit Insert to continue when you are done.\n";
while(1){
if(GetAsyncKeyState(VK_PLUS)){bpm++;if(bpm % 5 == 0){cout << bpm << endl;}}
if(GetAsyncKeyState(VK_MINUS)){bpm--;if(bpm % 5 == 0){cout << bpm << endl;}}
if(GetAsyncKeyState(VK_INSERT))break;
Sleep(100);
}
return bpm;
}
[/PHP]

Now to decipher how this code works.

[PHP]
int TellTime(){
//code
}
[/PHP]

Gets the Beats per Minutes you want and returns them. This will then be the input into the function:

[PHP]
int TellTime(int bpm){
//code
}[/PHP]

TellTime function will take your beats per minute and then Sleep for 60000/bpm milliseconds. This will take you to a millisecond number such as 1000 for 60 bpm... Then the most important part of this function

[PHP]
PlaySound(L"tick.wav", NULL, SND_ASYNC | SND_FILENAME);
[/PHP]

This plays the sound "tick.wav" from the current directory. Nothing else needs to be worried about.

Now all we have left is to link the functions in Main.cpp.

Create a new source code and insert this to link it.

[PHP]
#include "Includers.h"
using namespace std;
int GetBpm(); //Declares you want use of this function
int TellTime(int bpm); //Also declares you want use of this function

int main(){
start:
int bpm;//Creates an integer with no value, named bpm
bpm = GetBpm(); //Stores the return value of GetBpm() into the int bpm
TellTime(bpm); //Makes it go tick to the time of your custom bpm...
cout << "Start again? (Y/N)";
while(1){
if(GetAsyncKeyState(VK_Y))goto start;
if(GetAsyncKeyState(VK_N))break;
}
return 0;
}
[/PHP]

Now all that is left is to hit F5 and you will Build + Go. Then you can try out the program.

Hit That Thanks Button!

well that's helpful. If you put all the keys into a header file I would download it n keep it somewhere. course I can just make my own header to put em in.

[**HellaGoodCoders**]

I did put all the keys in a header file. They just have some extra stuff. It took a long time to finish this project. My comp == So retarded
