T3D 3dArrow Port

This is based off the original 3darrow resource found here;
www.garagegames.com/community/resources/authorID/90692

The fixes to this are posted else where and are by no means my own work,
other than this is what I did to get it to work in T3d 3.5.1 MIT!!

Ok first the engine changes I used.... open guiObjectView.cpp

around line 112, zero these out....

mCameraRot.set( 0.0f, 0.0f, 0.0f );
   mCameraPos.set( 0.0f, 0.0f, 0.0f );

in

void GuiObjectView::renderWorld( const RectI& updateRect )

add this....

// Set up pass transforms.       
   renderPass->assignSharedXform( RenderPassManager::View, MatrixF::Identity );    
   renderPass->assignSharedXform( RenderPassManager::Projection, GFX->getProjectionMatrix() );

right after this....

SceneRenderState state
   (
      gClientSceneGraph,
      SPT_Diffuse,
      SceneCameraState( GFX->getViewport(), frust, GFX->getWorldMatrix(), GFX->getProjectionMatrix() ),
      renderPass,
      false
   );

just under

void GuiObjectView::setOrbitDistance( F32 distance )

add...

// 3D Arrow Resource  
void GuiObjectView::setRotation(F32 x, F32 y, F32 z)  
{  
     mCameraRot.x = (x * 1.0f);  
     mCameraRot.y = (y * 1.0f);  
     mCameraRot.z = (z * 1.0f);  
}
// 3D Arrow Resource

at the very end of this file add....

// 3D Arrow Resource  
ConsoleMethod(GuiObjectView, setRotation, void, 5, 5,  
              "(float x, float y, float z)n"  
              "Sets the rotation for the loaded model..nn"  
              "param x x rotation value."  
              "param y y rotation value."  
              "param z z rotation value.")  
{  
   argc;  
   object->setRotation(dAtof(argv[2]), dAtof(argv[3]), dAtof(argv[4]));  
}  
// 3D Arrow Resource End

save and close..... Now open guiObjectView.h

add this around line 234....

void setRotation( F32 x, F32 y, F32 z ); // <- add this 3darrow

save and close..... Rebuild Engine!!

Now for the scripts.... in game/art/gui/playGui.gui add this to the bottom;

new GuiObjectView(direction) {
      shapeFile = "art/shapes/3darrow/arrow.dts";
      mountedNode = "mount0";
      lightColor = "0.6 0.58 0.5 1";
      lightAmbient = "0.5 0.5 0.5 1";
      lightDirection = "-0.57735 -0.57735 -0.57735";
      orbitDiststance = "5";
      minOrbitDiststance = "0.438834";
      maxOrbitDiststance = "5";
      cameraSpeed = "0.01";
      cameraRotation = "0 0 0";
      cameraZRot = "0";
      forceFOV = "0";
      reflectPriority = "0";
      renderStyle = "standard";
      margin = "0 0 0 0";
      padding = "0 0 0 0";
      anchorTop = "1";
      anchorBottom = "0";
      anchorLeft = "1";
      anchorRight = "0";
      position = "244 -102";
      extent = "532 483";
      minExtent = "8 2";
      horizSizing = "center";
      vertSizing = "bottom";
      profile = "GuiDefaultProfile";
      visible = "1";
      active = "1";
      tooltipProfile = "GuiToolTipProfile";
      hovertime = "1000";
      isContainer = "1";
      canSave = "1";
      canSaveDynamicFields = "0";
   };

save and close.... Now in game/scripts/client/client.cs add this to the end of file;

//3darrow
function clientCmdSetDirection(%x, %y, %z)  
{  
   %x = -0.5; // Hack to get the arrow to point down some.  
   %y = 0; // This value is not really needed at all, so nullify the results.  
   direction.setRotation(%x, %y, %z);  
   //echo(("clientCmdSetDirection rotation: " SPC %x SPC %y SPC %z));     
}

save and close.... Now in game/scripts/gui/playGui.cs in

function PlayGui::onWake(%this)

add....

%shapeName = "art/shapes/3darrow/arrow.dts";
      direction.setModel(%shapeName);

save and close.... Now in game/scripts/server/game.cs add this to the end of file;

//------------------------------------------------------------------------
//3darrow HUD
//------------------------------------------------------------------------

$aimTarget = 1052871; //set this to any game ID you want arrow to point to... 
  
function GameConnection::AimTarget( %this )  
{     
   if($aimTarget)  
   {           
      %player = %this.player;  
      %target = $aimTarget;  
        
      %playerTrans = (%player.getTransform());     
      %xPlayer = getWord(%playerTrans, 0);  
      %yPlayer = getWord(%playerTrans, 1);     
      %zRot = getWord(%playerTrans, 5);  
      %playerRot = getWord(%playerTrans, 6);  
           
      %targetPosition = (%target.getPosition());  
      %xTarget = getWord(%targetPosition, 0);  
      %yTarget = getWord(%targetPosition, 1);  
           
      %xDiff = %xTarget - %xPlayer;  
      %yDiff = %yTarget - %yPlayer;  
        
      // dont have to change it to degrees  
      // settransform automatically change it to degrees  
      %rotToTarget = mAtan(%xDiff, %yDiff);   
        
      if(%zRot < 0)  
         %playerRot = (2 * 22/7) - %playerRot;  
              
      // multiply by -1 because the rotation in 3dspace is oppositing the guiobjectview rotation  
      %rotation = -1 * (%rotToTarget - %playerRot);  
        
      commandToClient(%this, 'SetDirection', 0, -15, %rotation);  
   }  
   %this.schedule(25, AimTarget);  
}

save and close.... In game/scripts/server/gameCore.cs in

function GameConnection::onClientEnterGame(%this)

add....

// here you go just call the aimTarget here     
      // and you can set the $aimtarget anywhere and anytime you want.     
      %this.aimTarget();

save and close...... Run game and enoy, dont forget you can set this in console or script like so;

$aimTarget = 1052871; //set this to any game ID you want arrow to point to...
