It is easy to use with joyGetPosEx function to query the joystick / controller position under Windows!Required:
Identifier of the joystick to be queried. Valid values for uJoyID range from zero JOYSTICKID1 to 15. And:
Pointer to a JOYINFOEX structure that contains extended position information and the button status of the joystick. You must set the dwSize and dwFlags members or joyGetPosEx will fail. The information returned by joyGetPosEx depends on the flags you specify in dwFlags.
Long story short example program: This C++ code uses the Windows Multimedia Features to monitor joystick or controller input data and display it on the console. Here is a description of the code with comments: #include <iostream>
#include <windows.h>
#include <tchar.h>
using namespace std;
#pragma comment(lib, "winmm.lib")
int _tmain(int argc, _TCHAR* argv[])
{
JOYINFOEX info;
info.dwFlags = JOY_RETURNALL;
while (JOYERR_NOERROR == joyGetPosEx(JOYSTICKID1, &info))
{
// Clear the console to display the new joystick data.
system("cls");
cout << "Xpos:\t" << info.dwXpos << endl;
// X position of the joystick
cout << "Ypos:\t" << info.dwYpos << endl;
// Y position of the joystick
cout << "Zpos:\t" << info.dwZpos << endl;
// Z position of the joystick
cout << "Rpos:\t" << info.dwRpos << endl;
// R position of the joystick
cout << "Upos:\t" << info.dwUpos << endl;
// U position of the joystick
cout << "Vpos:\t" << info.dwVpos << endl;
// V position of the joystick
cout << "Buttons:\t" << info.dwButtons << endl;
// Status of the joystick buttons
cout << "ButtonNumber:\t" << info.dwButtonNumber << endl;
// Number of joystick buttons
cout << "POV:\t" << info.dwPOV << endl;
// POV (Point of View) switch position
}
cout << "No joystick/controller connected" << endl;
return 0;
}
This code uses the joyGetPosEx function to retrieve joystick or controller data and display it continuously on the console in a loop. It displays the positions of the various axes (X, Y, Z, R, U, V), the status of the joystick buttons, the number of buttons, and the position of the POV switch. If no joystick or controller is connected, the code prints the message "No joystick/controller connected". Note that using joyGetPosEx requires appropriate joystick hardware. On MSN: joyGetPosEx function and JOYINFOEX ! The standard joystick driver currently supports these five discrete directions. If an application can only accept the defined view values, it must use the JOY_RETURNPOV flag. If an application can accept other degree values, it should use the JOY_RETURNPOVCTS flag to get continuous data if it is available. The JOY_RETURNPOVCTS flag also supports the JOY_POV constants used with the JOY_RETURNPOV flag. FAQ 20: Updated on: 4 September 2024 10:14 |
