Helicopter, Helicopter, Pilot Man....

A few edits, added the full helicopter files for T3D 1.0 as drag and drop. Install a fresh copy and drop this over the top, add the two engine files and recompile. You will be able to add the helicopter after that. Original work and credits go to www.torquepowered.com/community/resource/view/9263/

www.dropbox.com/s/oimplfcjbb5jyof/helicopter-t3d.rar Full helicopter source and all files for T3D.

Now edit, vehicle.h
after

add

Pulling a bit of code from www.torquepowered.com/community/resources/view/9263/4#comment-51506 seems to have fixed the at rest stuck issue. You can embed the heli in the terrain and it will fly away like it wasn't. This was the simpliest code to insert and seems to work very well. I am not sure of any far reaching implications with the usage of this.

In vechile.cpp find the function for

void Vehicle::updatePos(F32 dt)

Point3F origVelocity = mRigid.linVelocity;

   // Update internal forces acting on the body.
   mRigid.clearForces();
   updateForces(dt);

[b]
   // Integrate forward
   if (!mRigid.atRest)
      mRigid.integrate(dt);
[/b]
	 // Update collision information based on our current pos.
   bool collided = false;
   if (!mRigid.atRest) {
      collided = updateCollision(dt);

      // Now that all the forces have been processed, lets
      // see if we're at rest.  Basically, if the kinetic energy of
      // the vehicles is less than some percentage of the energy added
      // by gravity for a short period, we're considered at rest.
      // This should really be part of the rigid class...
      if (mCollisionList.count) {
         F32 k = mRigid.getKineticEnergy();
				 F32 G = sVehicleGravity * dt;
         F32 Kg = 0.5 * mRigid.mass * G * G;
         if (k < sRestTol * Kg && ++restCount > sRestCount)
            mRigid.setAtRest();
      }
      else
         restCount = 0;
   }

[b]
   // Integrate forward
   //if (!mRigid.atRest)
   //   mRigid.integrate(dt);
[/b]

Add the helicopter code into the engine and recompile.

Edit, game/scripts/client/client.cs and at the bottom of this file paste this,

// Heli Resource Code Start //

//----------------------------------------------------------------------------
// Vehicle commands
//----------------------------------------------------------------------------

function clientCmdPopActionMap()
{
   echo("Popping Player action map " );
   movemap.pop();
}

function clientCmdPushActionMap()
{
   echo("Pushing Player action map " );
   movemap.push();
}
//----------------------------------------------------------------------------

function clientCmdPopActionMapHelicopterDriver()
{
   echo("Popping Helicopter Driver action map " );
      heliDriverMap.pop();
      }

function clientCmdPopActionMapHelicopterPassenger()//%vehicleType
{
   echo("Popping Helicopter Passenger action map " );
      heliPassengerMap.pop();
      }

//----------------------------------------------------------------------------

function clientCmdPushActionMapHelicopterDriver()
{
   echo("Pushing Helicopter Driver action map " );
      heliDriverMap.push();
}

function clientCmdPushActionMapHelicopterPassenger()
{
   echo("Pushing Helicopter Passenger action map " );
      heliPassengerMap.push();
}

// Heli Resource Code End //

Edit scripts/client/default.bind.cs and place this at the bottom

// Heli Resource Code Start //

function mouseJet(%val)
{
$mvTriggerCount3++;
}

function mouseJetdn(%val)
{
$mvTriggerCount4++;
}
moveMap.bindCmd(keyboard, "m", "commandToServer('MountVehicle');", "");

// Heli Resource Code End //

Edit scripts/cleint/init.cs and before

loadMaterials();

insert

// Heli Resource Code Start //
   exec("./heliDriverMap.cs");
   exec("./heliPassengerMap.cs");
   // Heli Resource Code End //

Now edit scripts/server/commands.cs and at the end of the file add

// Heli Resource Code Start //    
function serverCmdMountVehicle(%client)
{
   //Determine how far should the picking ray extend into the world?
   %selectRange = 3;

   // Only search for vehicles
   %searchMasks = $TypeMasks::vehicleObjectType;

   %pos = %client.player.getEyePoint();

   // Start with the shape's eye vector...
   %eye = %client.player.getEyeVector();
   %eye = vectorNormalize(%eye);
   %vec = vectorScale(%eye, %selectRange);

   %end = vectorAdd(%vec, %pos);

   %scanTarg = ContainerRayCast (%pos, %end, %searchMasks);

   // a target in range was found so select it
   if (%scanTarg)
   {
      %targetObject = firstWord(%scanTarg);
      echo("Found a vehicle: " @ %targetObject);
      onMountVehicle(%targetObject.getDataBlock(),
                     %client.player,
                     %targetObject);
   }
   else
   {
      echo("No object found");
   }
}

function serverCmdDismountVehicle(%client)
{
   doPlayerDismount(%client, %client.player, %true);
}


function serverCmdFindNextFreeSeat(%client)
{
   echo("serverCmdFindNextFreeSeat " @ %client.nameBase);

   // Is the vehicle moving? If so, prevent the player from switching seats
   if (isVehicleMoving(%client.player.mvehicle) == true)
      return;

   %newSeat = findNextFreeSeat(%client,
                               %client.player.mvehicle,
                               %client.player.mvehicle.getDataBlock());

   if (%newSeat != -1)
   {
      echo("Found new seat " @ %newSeat);

      setActiveSeat(%client.player,
                    %client.player.mvehicle,
                    %client.player.mvehicle.getDataBlock(),
                    %newSeat);
   }
   else
   {
      echo("No next free seat");
   }
}

// Heli Resource Code End //

Now, it player.cs replace your Armor::OnMount and Armor::OnUnMount functions with these. This will bind the action maps and should provide the correct flight functionality.

function Armor::onMount(%this, %obj, %vehicle, %node)
{
   // Node 0 is the pilot's position, we need to dismount his weapon.
   if (%node == 0)
   {
      
      %obj.setTransform("0 0 0 0 0 1 0");
      %obj.setActionThread(%vehicle.getDatablock().mountPose[%node], true, true);

      %obj.lastWeapon = %obj.getMountedImage($WeaponSlot);
      %obj.unmountImage($WeaponSlot);

      %obj.setControlObject(%vehicle);
      //%obj.client.setObjectActiveImage(%vehicle, 2);
    CommandToClient(%obj.client, 'PopActionMap', moveMap);
    CommandToClient(%obj.client, 'PushActionMapHelicopterDriver',heliDriverMap);
   }
   else
   {
      if (%vehicle.getDataBlock().mountPose[%node] !$= "")
         %obj.setActionThread(%vehicle.getDatablock().mountPose[%node]);
      else
         %obj.setActionThread("root", true);
   CommandToClient(%client, 'PopActionMap', moveMap);
   CommandToClient(%client, 'PushActionMap', $Vehicle::moveMaps[%seat]);
   }
}

function Armor::onUnmount(%this, %obj, %vehicle, %node)
{
   %obj.setActionThread("run", true, true);

   if (%node == 0)
   {
      %obj.mountImage(%obj.lastWeapon, $WeaponSlot);
      %obj.setControlObject("");
   }
   CommandToClient(%obj.client, 'PopActionMapHelicopterDriver', heliDriverMap);
   CommandToClient(%obj.client, 'PopActionMapHelicopterPassenger', heliPassengerMap);
   CommandToClient(%obj.client, 'PushActionMap', moveMap);
}

Now copy over the art and script files in the folder. The scripts are a little issue, there are some T3D scripts that cover the same functions. Let's get the engine in now before going through the scripts.



When your done, you should be able to have something similar to this below. You will notice, I get into it while it is above the ground. It gets 's stuck at this moment in the ground. There are multiple fixes that will be tested on this resource until we resolve this issue with it.
