Initial Inventory problems

by Tom Feni · in Torque Game Builder · 01/11/2006 (12:40 am) · 1 replies

I am trying to have a basic pickup inventory function but all it does is move the coin around.. :)

in items.cs
function createItems(%item)

{
   $starCoin = new t2dShape3D() { scenegraph = t2dScene; };
   $starCoin.setShape("./shapes/starcoin.dts");
   
   $starCoin.setCollisionActive(true, true);
   $starCoin.setCollisionPhysics(true, true);
   $starCoin.setCollisionCallback(true);
   //$starCoin.setLayer($playerLayer);
   //$starCoin.setGroup($playerGroup);
   $starCoin.setPosition( "40 96" );
   // Orientate the shape in 3D.
   $starCoin.setShapeRotation( "0 90 0" );
   // Set Detail Level.
   $starCoin.setDetailLevel( 0 );
   $starCoin.setShapeScale( "0.1 1 0.1" );


   $starCoin.setSize( 6 );
   //%shape.setLayer($playerLayer);
   //%shape.setGroup($playerGroup);

   // Automatically rotate the shape in 3D.
   $starCoin.setShapeAngularVelocity( "0 90 0" );

}

in inventory.cs
function item()
{
  $item = %item;
}

function pickup()
{
   %item.onPickup( %item );
   %item.setHidden();
}

function addInv()
{

   $player.setInventory++;
   
}

in player.cs
function createPlayer()
{
....
setInventory();
}

function setInventory()
{

   $playerInventory = 0;
}

in game.cs

function createLevel()
{
   $gravity = 200;
   $spawnPoint = "-80 90";
   $starCoin = %item;
   %testMap = new t2dTileMap()
   {
      scenegraph = t2dscene;
   };

    %testMap.loadTileMap("BerksQuest/client/maps/level02.map");

    //-----------------------------------
    // collision
    //-----------------------------------
    %collayer = %testMap.getTileLayer(0);
    %collayer.setPosition("50 50");
    %collayer.setLayer($platformLayer);
    %collayer.setGroup($platformGroup);
    %collayer.setTileSize("4 4");
    %collayer.setCollisionActive(false, true);
    //%colLayer.setCollisionPhysics(true, true);
    //%collayer.setCollisionMasks(BIT(1), BIT(1));
    %collayer.setCollisionMaterial(collisionMaterial);

    // ------------------------------------
    // boxes
    // ------------------------------------
    %boxlayer = %testMap.getTileLayer(1);
    %boxlayer.setPosition("50 50");
    %boxlayer.setTileSize("4 4");
    %boxlayer.setLayer($platformLayer);
    %boxlayer.setGroup($platformGroup);
    %boxlayer.setCollisionActive(false, true);
    //%boxLayer.setCollisionPhysics(true, true);
    //%boxlayer.setCollisionMasks(BIT(1), BIT(1));

    // --------------------------------------
    // ladders
    // --------------------------------------
    %ladlayer = %testMap.getTileLayer(2);
    %ladlayer.setPosition("50 50");
    %ladlayer.setLayer($platformLayer);
    %ladlayer.setGroup($platformGroup);
    %ladlayer.setTileSize("4 4");
    %ladlayer.setCollisionActive(false, true);
    //%ladLayer.setCollisionPhysics(true, true);
    //%ladlayer.setCollisionMasks(BIT(1), BIT(1));

    // ---------------------------------------
    // water
    // ---------------------------------------
    %watlayer = %testMap.getTileLayer(3);
    %watlayer.setPosition("50 50");
    %watlayer.setLayer($platformLayer);
    %watlayer.setGroup($platformGroup);
    %watlayer.setTileSize("4 4");
    %watlayer.setCollisionActive(false, true);
    //%watLayer.setCollisionPhysics(true, true);
    //%watlayer.setCollisionMasks(BIT(1), BIT(1));

    // ----------------------------------------
    // Triggers
    // ----------------------------------------
    %trilayer = %testMap.getTileLayer(4);
    %trilayer.setPosition("50 50");
    %trilayer.setLayer($platformLayer);
    %trilayer.setGroup($platformGroup);
    %trilayer.setTileSize("4 4");
    %trilayer.setCollisionActive(false, true);
    //%triLayer.setCollisionPhysics(true, true);
    //%trilayer.setCollisionMasks(BIT(1), BIT(1));

   $camera.setLimits(%collayer.getArea());
   createItems();
   movingBoxs();
   setInventory();
   resetPlayer($spawnPoint);

}

function t2dSceneObject::onCollision(%srcObj, %dstObj, %srcRef,
   %dstRef, %time, %normal, %contactCount, %contacts)
{
   switch (%srcObj.getGroup())
   {
      case $playerGroup:
         switch (%dstObj.getGroup())
         {
            case $platformGroup:
               collidePlayerPlatform(%normal);
         }
   }
   
   if (%srcObj == $playergroup)

         {
         if (%dstObj == %starCoin)
            {
            addInv();
            pickup();
            
            echo("anything happening yet");
           // $player.setImpulseForcePolar( getRandom()*360, 2000);

            }
          }
}



I think thats all the relevant code..

just curious since I dont know much about coding.. and I figured someone would know whats going on.. :)

I looked for some examples of inventory systems and all I find is the database one.. which is way more then I need.. :)

thanks in advance..

I'm not quite sure what's trying to happen but one thing that i picked up on...

in t2dSceneObject::onCollision , all the if section seems a little wrong to me. If looks like with that you're trying to test if the player collides with a coin, and that can be done above in the switch sections like so
switch (%srcObj.getGroup())
   {
      case $playerGroup:
         switch (%dstObj.getGroup())
         {
            case $platformGroup:
               collidePlayerPlatform(%normal);
            case $starGroup:
               addInv();
               pickup(%dstObj);
            
               echo("anything happening yet");
         }
   }
I've altered the bit at case $starGroup, but for this to work you need to add the coin objects to its own Group, and i'm not sure how good a practice this is if you have lots of objects all with a separate %object.setGroup($something);

It looks like the pickUp() function needs an object passed into it so i've added %dstObj as a paramter, the function definition will need to change to reflect this.
function pickup(%item)
{
   %item.onPickup( %item );
   %item.setHidden();
}

I've searched the reference for .onPickup() and .setHidden() and i cant find them so i cant help you with the contents of that function.

I'm not sure if this will help you much but at least its something to get started with, also i have to put my usual disclaimer that i've only had t2d a week and i hope i've not given you misinformation. I'm not quite sure of myself when it comes to t2d :P

You say this only moves the coin around but what is the overall effect you are trying to acheive with this? Touch the coin, make it disappear and then what?
