C++ (Cpp) get_keys_pressed Examples

Example #1

File: main.c Project: OpenSorcery/libdragon

/* input - do getButtons() first, then getAnalogX() and/or getAnalogY() */
unsigned short getButtons(int pad)
{
    // Read current controller status
    controller_scan();
    gKeys = get_keys_pressed();
    return (unsigned short)(gKeys.c[0].data >> 16);
