摇杆配置与XML编写
本帖最后由 VeyronC 于 2016-11-8 21:16 编辑USB 接上 Mad-Catz-FLY5-Stick 摇杆之后能自动识别到，默认状态下，油门、副翼、升降舵可用，方向舵等其他操作需要自己配置 xml 文件。 进入 FG 后，点 Help -> Joystick Configuration，可以进入摇杆配置界面，里面可以查看路径和配置操作。 若点击 ResetConfiguration，会自动使用 C:\ProgramFiles\FlightGear2.10.0.3\data\Input\Joysticks\Default\joystick.xml 下的配置文件。 若更改配置后，会自动跳到 C:\FlightGear\flightgear-debug\Input\Joysticks\Mad-Catz-FLY5-Stick.xml （这个路径是之前用另一个版本自己编译的路径，为何跳这了？） 点击 Refresh Joysticks 可以将更改保存。 Configuration File 处显示了文件路径。file:///C:/Users/cpr/AppData/Local/Temp/msohtmlclip1/01/clip_image002.png 摇杆里的移动杆对应 xml 里的标签 <axis n="几"></axis> 摇杆里的按键对应 xml 里的标签 <button n="几"></button>，对于赛钛客FLY5这款，对应按键上的数字是这里的 几+1。这个可以在上面的 Joystick Configuration 中试出来。 根据示例代码设置，并参考FG文件夹里面的 data\keyboard.xml 文件来配置。因为FLY5这款的移动杆有限，那么方向舵我想用按键来设置，就先看 keybord.xml 中内容和方向舵移动有关的按键项<key>，对应移植过去给<button>标签之内即可。
<key n="364"><name>Insert</name><desc>Move rudder left</desc><repeatable type="bool">true</repeatable><binding> <command>property-adjust</command> <property>/controls/flight/rudder</property> <step type="double">-0.05</step></binding>
</key>
<button n="9"> <desc type="string">Custom</desc> <repeatable type="bool">true</repeatable> <binding> <command type="string">property-adjust</command> <property type="string">/controls/flight/rudder</property> <step type="double">-0.05</step> </binding>
</button>
设置视角切换，可以在 JoysickConfiguration 中设置某个按键为 View Cycle Forwards。 一套简易实用的自定义 xml 摇杆配置代码如下：
<?xml version="1.0"?> <PropertyList><name type="string">Mad CatzF.L.Y.5 Stick</name><axis> <!--若不写n值，默认为0--> <desc type="string">Aileron</desc> <binding> <command type="string">property-scale</command> <property type="string">/controls/flight/aileron</property> <dead-band type="double">0</dead-band> <factor type="double">1</factor> <offset type="double">0</offset> </binding></axis> <axis n="1"> <desc type="string">Elevator</desc> <binding> <command type="string">property-scale</command> <property type="string">/controls/flight/elevator</property> <dead-band type="double">0</dead-band> <factor type="double">-1</factor> <offset type="double">0</offset> </binding></axis> <axis n="2"> <desc type="string">Throttle</desc> <binding> <command type="string">nasal</command> <script type="string">controls.throttleAxis();</script> </binding></axis> <axis n="6"> <desc type="string">View(horizontal)</desc> <low> <binding> <command type="string">nasal</command> <script type="string">setprop("/sim/current-view/goal-heading-offset-deg", getprop("/sim/current-view/goal-heading-offset-deg") + 30);</script> </binding> </low> <high> <binding> <command type="string">nasal</command> <script type="string">setprop("/sim/current-view/goal-heading-offset-deg", getprop("/sim/current-view/goal-heading-offset-deg") - 30);</script> </binding> </high></axis> <axis n="7"> <desc type="string">View(vertical)</desc> <low> <binding> <command type="string">nasal</command> <script type="string">setprop("/sim/current-view/goal-pitch-offset-deg", getprop("/sim/current-view/goal-pitch-offset-deg") - 20);</script> </binding> </low> <high> <binding> <command type="string">nasal</command> <script type="string">setprop("/sim/current-view/goal-pitch-offset-deg", getprop("/sim/current-view/goal-pitch-offset-deg") + 20);</script> </binding> </high></axis> <button> <desc type="string">Brakes</desc> <repeatable type="string">false</repeatable> <binding> <command type="string">nasal</command> <script type="string">controls.applyBrakes(1);</script> </binding> <mod-up> <binding> <command type="string">nasal</command> <script type="string">controls.applyBrakes(0);</script> </binding> </mod-up></button> <button n="9"><!--对应FLY5摇杆上按键10--> <desc type="string">Custom</desc> <repeatable type="bool">true</repeatable> <binding> <command type="string">property-adjust</command> <property type="string">/controls/flight/rudder</property> <step type="double">-0.05</step> </binding></button> <button n="10"> <desc type="string">Custom</desc> <repeatable type="bool">true</repeatable> <binding> <command type="string">property-adjust</command> <property type="string">/controls/flight/rudder</property> <step type="double">0.05</step> </binding></button> <button n="13"> <desc type="string">View CycleForwards</desc> <binding> <command type="string">nasal</command> <script type="string">view.stepView(1);</script> </binding> <repeatable type="double">0</repeatable></button></PropertyList>
讲的很清楚，谢谢分享！ 写的很好，多谢楼主分享 FEWDFER
