Step #1
// ------------------------------------------
// defaultGame.cs
// ------------------------------------------

function DefaultGame::clearDeployableMaxes(%game)
{

      $TeamDeployedCount[%i, JumpadDeployable] = 0;

}

Step #2
// ------------------------------------------
// deployables.cs
// ------------------------------------------

2a)Near the top of the file add this:

$TeamDeployableMax[JumpadDeployable] = 5;


2b)All of this takes place in function ShapeBaseImageData::onDeploy:

   if(%item.deployed.className $= "DeployedTurret")
      %className = "Turret";
   else
      %className = "StaticShape";

   becomes:

   if(%item.deployed.className $= "DeployedTurret")
      %className = "Turret";
   else if (%item.deployed.className $= "Jumpad")
      %className = "Item";
   else
      %className = "StaticShape";

Next:

   %deplObj = new (%className)()
   {
      dataBlock = %item.deployed;
   };

   becomes:

   if (%item.deployed.classname $= "Jumpad")
   {
      %deplObj = new (%className)()
      {
         dataBlock = %item.deployed;
         scale = "0.55 0.7 0.3";
      };
   }
   else
   {
      %deplObj = new (%className)()
      {
         dataBlock = %item.deployed;
      };
   }

Next:

   if(%className $= "Turret")
      %deplObj.setDeployRotation(%item.surfacePt, %item.surfaceNrm);
   else
      %deplObj.setTransform(%item.surfacePt SPC %rot);

   becomes:

   if(%className $= "Turret")
      %deplObj.setDeployRotation(%item.surfacePt, %item.surfaceNrm);
   else if (%item.deployed.classname $= "Jumpad")
      %deplObj.setDeployRotation(getWords(%item.surfacePt, 0, 1) SPC getWord(%item.surfacePt, 2) + 0.1, %item.surfaceNrm);
   else
      %deplObj.setTransform(%item.surfacePt SPC %rot);

Next:

   %deplObj.deploy();

   becomes:

   if (%classname !$= "Item")
      %deplObj.deploy();


Step #3
// ------------------------------------------
// inventoryHud.cs
// ------------------------------------------
Add this near the top of the file:

$InvPack[18] = "Jump Pad";
$NTInvPack[11] = "Jump Pad";
$NameToInv["Jump Pad"] = "JumpadDeployable";


Step #4
// ------------------------------------------
// pack.cs
// ------------------------------------------
exec("scripts/packs/Jumpad.cs");


Step #5
// ------------------------------------------
// repairpack.cs
// ------------------------------------------
Find both instances of '%searchMasks =' in the file and add '| $TypeMasks::ItemObjectType' so the jumpad can be repaired.


Step #6
// ------------------------------------------
// player.cs
// ------------------------------------------

6a) In each player datablock add this. Since it's a deployable, only mediums and heavies need it.
   max[JumpadDeployable] = 1;


6b) At the bottom of function Armor::onCollision add this: (This handles the impulse. Adjust the 2200 for horizontal push and 7500 for vertical push).

      else if (%className $= "Jumpad")
      {
         if (%col.team == %obj.team)
         {
            %position = getWords(%obj.getTransform(), 0, 2);
            %vel = %obj.getVelocity();
            %x1 = getWord(%vel, 0) * 2200;
            %y1 = getWord(%vel, 1) * 2200;
            %impulseVec = %x1 SPC %y1 SPC 7500;
            %obj.applyImpulse(%position, %impulseVec);
            %obj.playAudio(0, MortarFireSound);
         }
      }


Step #7
// ------------------------------------------
// Jumpad.cs
// ------------------------------------------
Create a new file called Jumpad.cs in your packs directory and add all this:

//
//
