            Create an Interactive boat simulation 
          
       
       
       
       
      You
         can create an interactive motor boat simulation by combining an
         ocean, a motor boat, and some hotkeys to drive the boat.
      
      
         - Select 
                     Fluid Effects > Ocean > Create Ocean >  . .The Create Ocean options
               window appears. 
             
- Turn
            on Attach to Camera and Create
               Preview Plane, and then click Create Ocean. 
         
- Select
            the boat geometry.
         
- Select 
                     Fluid Effects > Ocean > Make Motor Boats. 
            Maya attaches a locator to the boat with built-in
               expressions to simulate buoyancy effects.
             
- Select
            the perspective camera (persp) and select 
                     Edit > Group.
            This creates a group and puts the perspective camera in it.
         
- In
            the Connection Editor(Windows
               > General Editors > Connection Editor), do the
            following:
            
               - Connect
                  the boat locator (created in step #4) Translate x and Translate
                  z attributes to the transform (ocean height field) Translate x and
                  Translate z attributes respectively.
               
- Connect
                  the locator Translate x and Translate z attributes to the camera group
                  (created in step #5) Translate x and Translate z attributes.
               
 This connects the movement of the boat along
               the ocean plane to the ocean and to the movement of the camera.
             
- Select
            the boat locator and in the Attribute Editor open
            the Extra Attributes section. 
         
- Switch
            to shaded mode.
         
- Playback
            the scene and adjust the throttle and rudder settings.
         
To speed up the simulation, you can make the Wave
            Turbulence zero on the ocean shader and instead increase Num
            Frequencies. Increasing the Wave Height also
         makes the simulation more dramatic.
      
      Hotkeys
         
         Create hotkeys for the following commands and
            use them to drive the boat.
         
         Stop Boat Key
            
            setAttr locator1.throttle 0 setAttr locator1.rudder 0
Increase Throttle
            
            float $t = `getAttr locator1.throttle`; setAttr locator1.throttle ($t + 0.5);
Decrease Throttle
            
            float $t = `getAttr locator1.throttle`; $t -= 0.5; if( $t < 0 ) $t = 0.0; setAttr locator1.throttle $t;
rudder Left
            
            float $t = `getAttr locator1.rudder`; $t += 2.0; if( $t > 20 ) $t = 20; setAttr locator1.rudder $t;
rudder Right
            
            float $t = `getAttr locator1.rudder`; $t -= 2.0; if( $t < -20 ) $t = -20; setAttr locator1.rudder $t;
