First T2D Tutorial - Stuck

by David Taylor · in Torque Game Engine · 03/19/2006 (10:59 pm) · 2 replies

As embarrassing as it is to admit it, the first piece of code in the BasicTutorial.pdf has me stumped. As far as I can tell, my game.cs scripting should read like this:

//---------------------------------------------------------------------------------------------
// Torque 2D.
// Copyright (C) GarageGames.com, Inc.
//---------------------------------------------------------------------------------------------


//---------------------------------------------------------------------------------------------
// setupT2DScene
// This function is the starting point for all game specific code.
//---------------------------------------------------------------------------------------------
function setupT2DScene()
{
// Create our scenegraph
new t2dSceneGraph(t2dScene);

// Associate Scenegraph with Window.
sceneWindow2D.setSceneGraph( t2dScene );

// Set the current camera position
sceneWindow2D.setCurrentCameraPosition("0 0 100 75");

// add an image to the screen
datablock t2dImageMapDatablock(playershipImageMap)
{
imageMode = full;
imageName = "~/data/images/playerShip";

$player = new t2dStaticSprite() { scenegraph = t2dScene; };
$player.setPosition("-35 0");
$player.setSize("14 7");
$player.setImageMap(playershipImageMap);
};

}

That is supposed to draw an image, (playerShip.png), to the screen, but it doesn't. As the documentation doesn't show the complete code required after each step, I may well have put portions in the wrong area, although the following has nothing drawing either:

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

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


//---------------------------------------------------------------------------------------------
// setupT2DScene
// This function is the starting point for all game specific code.
//---------------------------------------------------------------------------------------------
function setupT2DScene()
{
// Create our scenegraph
new t2dSceneGraph(t2dScene);

// Associate Scenegraph with Window.
sceneWindow2D.setSceneGraph( t2dScene );

// Set the current camera position
sceneWindow2D.setCurrentCameraPosition("0 0 100 75");

// add an image to the screen
datablock t2dImageMapDatablock(playershipImageMap)
{
imageMode = full;
imageName = "~/data/images/playerShip";
};

$player = new t2dStaticSprite() { scenegraph = t2dScene; };
$player.setPosition("-35 0");
$player.setSize("14 7");
$player.setImageMap(playershipImageMap);

}

Can anyone explain what I've done wrong here?

BTW you should post this in the T2D Forums

Try something like this:

function setupT2DScene()
{
   // Create our scenegraph
   new t2dSceneGraph(t2dScene);
   // Associate Scenegraph with Window.
   sceneWindow2D.setSceneGraph( t2dScene );
   // Add custom game code here...
   createPlayer();
}

// this function probably should go in it's own file, but that's really your preference.
function createPlayer()
{
   $player = new t2dStaticSprite() { scenegraph = t2dScene; };
   $player.setPosition("-35 0");
   $player.setSize("14 7");
   $player.setImageMap(playershipImageMap);
}

and in ~/data/content/datablocks.cs

datablock t2dImageMapDatablock(playershipImageMap)
{
   imageMode = full;
   imageName = "~/data/images/playerShip";
   filterPad = false;
 };


Now I haven't tried this, but it should work...

I just read the PDF, and I think possibly could use more clarification there.

By the way, there are more tutorials on TDN. I suggest the platformer tutorial, it's been updated and you really learn alot from it.

Thanks, Dave. That worked. :)

I just wish the tutorial had said something similar, lol - it never even hinted to adding scripting to datablocks.cs.

Thanks for the link - I'll be referring to that quite a lot in the future. :)
