Loading the Next Level in TGB

by JesseL · in Torque Game Builder · 08/28/2007 (11:08 am) · 9 replies

I've gone through a couple of walk-throughs trying to figure out how to load the next level. However, I must be stupid because I keep failing at using the functions that I've learned and commands.
Everytime I try to load a level like level1.t2d I get the error message:

Error loading level ~/data/levels/level1.t2d. Invalid file.

even though its there.

***Datablocks.cs***

if(!isObject(LevelEndTimerTemplate)) new t2dSceneObjectDatablock(LevelEndTimerTemplate)
{
  class="LevelEndTimerClass";
  sceneDuration="10000";
  nextLevel="baseLevel.t2d";
};


***level.cs***

$basePath = "~/data/levels/";

function LevelEndTimerClass::onLevelLoaded(%this, %scenegraph)
{
  %scenegraph.updateList.add(%this);  
  %this.startTime = %this.getSceneGraph().getSceneTime();
}


function LevelEndTimerClass::onUpdateScene(%this)
{
  %currentTime = %this.getSceneGraph().getSceneTime();
  %elapsed = mRound((%currentTime - %this.startTime) * 1000);
  
  if (%elapsed >= %this.sceneDuration)
  {
    %level = $basePath @ %this.nextLevel;
    if (isFile( %level ) || isFile( %level @ ".dso"))
      sceneWindow2D.schedule(10, loadLevel, %level);
  }  
}

****player.cs****

function LevelEndTimerClass::onLevelLoaded(%this, %scenegraph)
{
   echo("Times UP");
  %level = $basePath @ %this.nextLevel;
  if (isFile( %level ) || isFile( %level @ ".dso"))
    sceneWindow2D.schedule(%this.sceneDuration, loadLevel, %level);
}

I just realized that if I wanted to create a cat that caught on fire and ran up a telephone pole and then burst into a blue waterfall. That wouldn't be to hard!

    Try loading the level with a reference starting at the location of the executable.

    @Jason

    The "game/data/levels/level1.t2d" worked. Thanks

    I have a similar problem. Every time I try to a load a next level the TGB crashes.
    By default the first level loads and plays but after the timer runs out I'd like to load the next level.
    Here's where is crashes:

    sceneWindow2D.loadLevel("~/data/levels/level2.t2d");

    Try scheduling the load, or the funciton that loads, like this.

    SceneWindow2D.schedule(0, "loadLevel", "~/data/levels/level2.t2d");

    As you can see level 1 loads by default just fine but there is no log entry about the TGB crash when loading level 2.

    SceneWindow2D.schedule(0, "loadLevel", "game/data/levels/level2.t2d");

    This code worked to load the next level.

    However, this still doesn't solve the problem of why TGB crashed without an error trap.

    There's a missing 
    try
	{
		foo();
	}
	catch(...)
	{
		cout << "Error: bad things happened\n";
	}
    somewhere

    The problem with loading a level is that it immediately deletes the old scene and creates a new one, then returns. But, you're in a function that is referencing something in the deleted, old scene so it crashes. "LoadLevel" is written in script so I suppose it's possible to rewrite the code so that you don't need to schedule it. If someone codes this I've love a copy. I tried once and it failed so I undid the changes and left it alone.

    This might be overkill, but I don't have enough time to read through to find the exact problem, but I did a GDC demo that had to load levels. The full scripts were released here, so you can look through and find the level loading code really easily. It was a simple game.

    I also tried to get the TGB Reference to be clearer on this issue to avoid these threads, so check that out, though it pretty much says what Nikos just said, if I remember correctly.

    Hope that link helps a bit :)
