ProcessingでPS3のコントローラを使う(Win & Mac)

ここの方法でできそうだったけど、コントローラが微妙に違うのでできないっぽい。

procontrolのexampleのprintDevicesでDevice名を確認する

自分のDevice名はMotioninJoy Virtual Game Controllerということなので変更する。

しかし依然としてgetSliderとかでNULLポインタが入ってる。しばらく試行錯誤した結果、文字列じゃなくて配列番号でアクセスすればいいことに気づいた。

　修正前
ControllSlider sliderX = device.getSlider("x");
　修正後１　まだダメ
ControllSlider sliderY = device.getSlider("7");
　最終版　文字列じゃなくて数字
ControllSlider sliderX = device.getSlider(7);

以下が動いたコード

import procontroll.*;
import java.io.*;

ControllIO controll;
ControllDevice device;
ControllStick stick;
ControllButton button;

void setup(){
  size(400,400);
  
  controll = ControllIO.getInstance(this);

  //device = controll.getDevice("PLAYSTATION(R)3 Controller");
  device = controll.getDevice("MotioninJoy Virtual Game Controller");
  device.printSticks();
  device.printSliders();
  device.printButtons();
  device.setTolerance(0.05f);
  
  //ControllSlider sliderX = device.getSlider("x");
  //ControllSlider sliderY = device.getSlider("y");
  ControllSlider sliderX = device.getSlider(7);
  ControllSlider sliderY = device.getSlider(6);

  stick = new ControllStick(sliderX,sliderY);
   
  button = device.getButton(8);
  
  fill(0);
  rectMode(CENTER);
}

float totalX = width/2;
float totalY = height/2;

void draw(){
  background(255);


  if(button.pressed()){
    fill(255,0,0);
  }else{
    fill(0);
  }

  totalX = constrain(totalX + stick.getX(),10,width-10);
  totalY = constrain(totalY + stick.getY(),10,height-10);

  rect(totalX,totalY,20,20);
}

(追記)Macだとやり方が違った。
