Detailed Description

This module provides classes and functions for managing gamepad input.

The pad module offers functionalities to track and handle the state of gamepad buttons, integrating with NES controller emulation for touch screen inputs. It is designed for use in debugging environments, providing visual feedback and interaction through gamepad input.

The module is not intended for direct use in production games where a serial console does not exist. Its primary purpose is for debugging and development tools.

Note

This module serves only as a utility to emulate an NES controller on a touch panel, and its use is not recommended.

Usage example:

#include <stdio.h>
#include <beep8.h>
#include <nesctrl.h>
#include "pad.h"
 
// Define NES controller configuration
CfgNesCtrl cfg;
cfg.left_pix = 10;
cfg.top_pix = 10;
cfg.radius_pix = 5;
cfg.img_utile = B8_PPU_MAX_WTILE - 10;
cfg.img_vtile = B8_PPU_MAX_HTILE - 20;
cfg.img_pal = 1;
cfg.clear_color = B8_PPU_COLOR_BLACK;
cfg.debug_visual = true;
 
// Create an instance of CPadObj
CPadObj pad(0, &cfg);
 
// Main loop
while (true) {
    pad.vOnStep();
    // Initialize draw command buffer
    b8PpuCmd cmd;
    pad.vOnDraw(&cmd);
    
    // Check button states
    if (pad.GetCntHold(EPad::BTN_A) > 0) {
        printf("A button is being held\n");
    }
    if (pad.GetCntRelease(EPad::BTN_B) > 0) {
        printf("B button is released\n");
    }
    // Check other button states as needed
    // ...
 
    // Other game logic and rendering
    // ...
}
