以GTAV操作手法於FlightGear飛Cessna 172P - XBOX360搖桿XML檔設定

GTAV PS4控制器按鍵對應

• 左操作桿-左右: 副翼(Aileron)，操作桿向右，飛機右滾轉
• 左操作桿-上下: 升降舵(Elevator)，操作桿向下、升降舵向下
• L1: 方向舵(Rudder)左擺
• R2: 方向舵右擺
• L2: 熄火/減速
• R2: 發動/加速
• 右操作桿-左右: heading(or yaw) 視向(view direction)，操作桿向右→往右看
• 右操作桿-上下: pitch 視向，操作桿向下→往下看
• 左操作桿-按下: 收/放 起落架
• 右操作桿-按下: 按下-視向轉正後方；放開-視向轉回正前方
• 觸控版: 改變視角
• OPTIONS按鈕: 暫停

FlightGear控制器操作設定方法

FlightGear內的搖桿設定GUI功能有限，為達目標需編輯xml檔。

指定連結到特定xml檔

首先，編輯/FlightGear/data/joysticks.xml如下(參考網頁)

<PropertyList>
  <js n="0" include="Input/Joysticks/custom.xml"/>
</PropertyList>

如此，可強制第一支控制器js n="0"(基本上也只會插一個)以/FlightGear/data/Input/Joysticks/custom.xml對應操作按鍵。

編輯joystick xml檔

基本編輯方法建議參考此教學與/data/Docs/readme Command章節。以下僅就如何於各軸(axis)、按鈕(button)實現GTAV操作對應進行說明。

左操作桿-左右

<axis n="0">
  <binding>

property-scale command將property aileron之value設為axis值

    <command type="string">property-scale</command>
    <property type="string">/controls/flight/aileron</property>
  </binding>
</axis>

左操作桿-上下

<axis n="1">
  <binding>
    <command type="string">property-scale</command>
    <property type="string">/controls/flight/elevator</property>

因左操作桿向下為正，而elevator向上為正，故設factor為-1以反轉

    <factor type="double">-1</factor>
  </binding>
</axis>

L1-R1

XBOX 360搖桿之L1-R1不是類比，不能直接對應成L1-R1按多少→Rudder擺多少。
因此，設定成按下R1→Rudder持續向右擺，放開→回歸原點；按下L1→Rudder持續向左擺，方開→回歸原點。

L1

<button n="4">
  <binding>

property-interpolate command以設定之rate變動property rudder至value

    <command type="string">property-interpolate</command>
    <property type="string">/controls/flight/rudder</property>

Rudder左擺極值為-1

    <value type="double">-1</value>

設定rate，即每秒變動量

    <rate type="double">0.5</rate>
  </binding>

mod-up表放開按鈕

  <mod-up>
    <binding>
      <command type="string">property-interpolate</command>
      <property type="string">/controls/flight/rudder</property>

放開L1 Rudder回中心，而中心值為0

      <value type="double">0</value>
      <rate type="double">0.5</rate>
    </binding>
  </mod-up>
</button>

R1

<button n="5">
  <binding>
    <command type="string">property-interpolate</command>
    <property type="string">/controls/flight/rudder</property>

Rudder右擺極值為1

    <value type="double">1</value>
    <rate type="double">0.5</rate>
  </binding>
  <mod-up>
    <binding>
      <command type="string">property-interpolate</command>
      <property type="string">/controls/flight/rudder</property>
      <value type="double">0</value>
      <rate type="double">0.5</rate>
    </binding>
  </mod-up>
</button>

L2-R2

這個最複雜，因為R2同時要包含油門控制+引擎發動，L2要同時包含煞車+引擎熄火，使用nasal script處理

<axis n="2">
  <binding>
    <command type="string">nasal</command>
    <script type="string">

於script中取得axis值

      var axisValue = cmdarg().getNode("setting").getValue(); 

若引擎未啟動、且R2按到接近底(至底axis值為-1)，將starter switch設為1，啟動引擎

      if(getprop("/engines/engine/running") != 1
    and -0.9 > axisValue){
  setprop("/controls/switches/starter", 1);

若magnetos未設為3，設為3

  if(getprop("/controls/engines/engine/magnetos") != 3){ <!-- magnetos setting -->
    setprop("/controls/engines/engine/magnetos", 3);
  }
      }

若引擎已啟動，將starter switch設回0

      else{
 setprop("/controls/switches/starter", 0); 
      }

      <!-- axisValue 0~-1, R2, throttle -->

若axis值小於0，即按R2(0~-1)，設定油門(0~1)為axis反轉值

      if(0 >= axisValue){
  setprop("/controls/engines/engine/throttle", -axisValue);
      } 

      <!-- axisValue 0~1, L2, brake -->

若axis值大於0，即按L2(0~1)，設定左右煞車(0~1)為axis值

      if(axisValue >= 0){ # L2 is positive (0 ~ 1)
 setprop("/controls/gear/brake-left", axisValue);
 setprop("/controls/gear/brake-right", axisValue);
      } 

若axis值大於0.8，即L2按接近底，將magnetos設為0，引擎熄火

      if(axisValue > 0.8 and getprop("/controls/engines/engine/magnetos") != 0){
 setprop("/controls/engines/engine/magnetos", 0)
      }
    </script>
  </binding>
</axis>

右操作桿-左右

<axis n="4">

axis值約小於-0.9，即右操作桿左擺至接近極限時為low。

  <low> <!-- left --> <!-- axis value < -0.9 -->

動作需重複，即右操作桿左擺時持續減小pitch數值

    <repeatable type="string">true</repeatable>
    <binding>

property-adjust command用以將property數值加上step值

      <command type="string">property-adjust</command>
      <property type="string">/sim/current-view/goal-heading-offset-deg</property>
      <step type="double">-1</step>
    </binding>
  </low>

axis值約大於0.9，即右操作桿右擺至接近極限時為high。

  <high> <!-- right --> <!-- axis value > 0.9 -->
    <repeatable type="string">true</repeatable>
    <binding>
      <command type="string">property-adjust</command>
      <property type="string">/sim/current-view/goal-heading-offset-deg</property>
      <step type="double">1</step>
    </binding>
  </high>
</axis>

右操作桿-上下

<axis n="3">

axis上擺至接近極限為low

  <low>
    <repeatable type="string">true</repeatable>
    <binding>
      <command type="string">property-adjust</command>
      <property type="string">/sim/current-view/goal-pitch-offset-deg</property>
      <step type="double">-1</step>
    </binding>
  </low>

axis上擺至接近極限為high

  <high>
    <repeatable type="string">true</repeatable>
    <binding>
      <command type="string">property-adjust</command>
      <property type="string">/sim/current-view/goal-pitch-offset-deg</property>
      <step type="double">1</step>
    </binding>
  </high>
</axis>

左操作桿-按下

Cessna 172起落架不能收，跳過

右操作桿-按下

按下看正後方，放開跳回正前方。

<button n="9">

設heading為180度 (正後方)

  <binding>
    <command type="string">property-assign</command>
    <property type="string">/sim/current-view/goal-heading-offset-deg</property>
    <value type="double">180</value>
  </binding>

設pitch為0度

  <binding>
    <command type="string">property-assign</command>
    <property type="string">/sim/current-view/goal-pitch-offset-deg</property>
    <value type="double">0</value>
  </binding>

放開

    <mod-up>

設heading為0度 (正前方)

      <binding>
 <command type="string">property-assign</command>
 <property type="string">/sim/current-view/goal-heading-offset-deg</property>
 <value type="double">0</value>
      </binding>

設pitch為0度

      <binding>
 <command type="string">property-assign</command>
 <property type="string">/sim/current-view/goal-pitch-offset-deg</property>
 <value type="double">0</value>
      </binding>
    </mod-up>
</button>

觸控板

用BACK按鈕代替，利用property-cycle command使property於設定之value循環

<button n="6">
  <binding>
    <command type="string">property-cycle</command>
    <property type="string">/sim/current-view/view-number</property>

cockpit view

    <value>0</value>

model view

    <value>7</value>

chase without yaw view

    <value>5</value>
  </binding>
</button>

OPTIONS按鈕

用START按扭代替，直接pause command就好，easy。

<button n="7"> # START button
  <desc type="string">pause</desc>
  <repeatable type="string">false</repeatable>
  <binding>
    <command type="string">pause</command>
  </binding>
</button>

dead-band

前面說明省略dead-band部分。FlightGear之dead-band 結果以下程式碼說明 (可看joystick文件?)
README.Joystick.html，User Guid to FGInput - Joystick And Keyboard Binding For FlightGear
實際dead-band效果如下函式 (1 >= input >= -1, 1 > deadBand > 0 )

double doDeadBand(double input, double deadBand)
{
  if(input >= deadBand){
    return (input - deadBand) / (1 - deadBand);
  }

  if(input > -deadBand){
    return 0.0;
  }

  return -(abs(input) - deadBand) / (1 - deadBand);
}
