LevelButton behaviour on TDN not working?

#1 I didn't try that but I guess you have to use the filename for it, or is play the filename of that level you want to load?

#2 "Play" is the name of the scene in the project I'm trying to load.

#3 I spent a good chunk of time this past weekend working on a similar problem to yours. After crashing TGB about a million times trying to transition from a title screen "level" to my main game level, I sifted through the forums to try and figure out how to load levels properly and here is what I found:

Quote:In general, a function attached to an object in a scenegraph should not directly load a level, in my experience. The problem is that before the new level is loaded, the current level is unloaded, which includes unloading the object currently in the act of loading a new level. You would expect unpredictable results.

So in order to have a button that loads a new level, you need to use a GuiBitmapButtonCtrl.

#4 Thanks.

#5 Guys I don't think that's actually the case... Your behavior could always schedule a function that would load the new level into the scenegraph. As long as you use the schedule function properly such as this:

schedule( 1000, 0, "loadnewscene", %newscene);

and not this way

object.schedule( 1000, "loadnewscene", %newscene);

I see no reason why it wouldn't work as expected.

#6 ....

Since everything is being done via behaviors, I've always used %this.schedule. Plain old schedule works though, just tested it. Oh well, guess I can scrap my GUI overlay and go back to sceneObjects - which isn't that bad because I hate working with the GUI editor anyway. Thanks Joe.

#7 OK, as a newbie programmer how do I make this function in the loadlevel.cs code ...

if (!isObject(LevelButtonBehavior))
{
   %template = new BehaviorTemplate(LevelButtonBehavior);
   
   %template.friendlyName = "Level Button";
   %template.behaviorType = "GUI";
   %template.description  = "Loads a new level when clicked";

   %template.addBehaviorField(hoverImage, "The image to display when mousing over the object", object, "", t2dImageMapDatablock);
   %template.addBehaviorField(hoverFrame, "The frame of the hoverImage to display", int, 0);
   %template.addBehaviorField(clickImage, "The image to display when clicking on the object", object, "", t2dImageMapDatablock);
   %template.addBehaviorField(clickFrame, "The frame of the clickImage to display", int, 0);
   %template.addBehaviorField(level, "The level to load on mouse up", string, "");
   // ADD SOMETHING HERE ???
}

function LevelButtonBehavior::onBehaviorAdd(%this)
{
   %this.owner.setUseMouseEvents(true);
   
   %this.startImage = %this.owner.getImageMap();
   %this.startFrame = %this.owner.getFrame();
}

function LevelButtonBehavior::onMouseDown(%this, %modifier, %worldPos)
{
   if (!isObject(%this.clickImage))
      return;
   
   %this.owner.setImageMap(%this.clickImage, %this.clickFrame);
}

function LevelButtonBehavior::onMouseUp(%this, %modifier, %worldPos)
{
   if (isObject(%this.hoverImage))
      %this.owner.setImageMap(%this.hoverImage, %this.hoverFrame);
   else
      %this.owner.setImageMap(%this.startImage, %this.startFrame);
   
   	  sceneWindow2D.schedule("1","loadLevel",expandFilename( %this.level ) ); 
        // I ASSUME IT GOES HERE ... schedule( 1000, 0, "loadnewscene", %newscene);
}

function LevelButtonBehavior::onMouseEnter(%this, %modifier, %worldPos)
{
   if (!isObject(%this.hoverImage))
      return;
   
   %this.owner.setImageMap(%this.hoverImage, %this.hoverFrame);
}

function LevelButtonBehavior::onMouseLeave(%this, %modifier, %worldPos)
{
   %this.owner.setImageMap(%this.startImage, %this.startFrame);
}

#8 The "level" value you set for that behavior needs to be a path to a .t2d scene/level file... for example "game/data/levels/playground.t2d".

#9 The full path? Oh, that explains it. I thought it simply needed to be the name. I will try in the morning game/data/levels/Play.t2d.

Thanks Matthew, that was it!

#10 I've got the same problem...please help...and also, does the bahaviour have to be assigned toa static sprite or ta a text object?

if (!isObject(LevelButtonBehavior))
{
%template = new BehaviorTemplate(LevelButtonBehavior);

%template.friendlyName = "Level Button";
%template.behaviorType = "GUI";
%template.description = "Loads a new level when clicked";

%template.addBehaviorField(hoverImage, "The image to display when mousing over the object", object, "", t2dImageMapDatablock);
%template.addBehaviorField(hoverFrame, "The frame of the hoverImage to display", int, 0);
%template.addBehaviorField(clickImage, "The image to display when clicking on the object", object, "", t2dImageMapDatablock);
%template.addBehaviorField(clickFrame, "The frame of the clickImage to display", int, 0);
%template.addBehaviorField(level, "The level to load on mouse up", string, "");
}

function LevelButtonBehavior::onBehaviorAdd(%this)
{
%this.owner.setUseMouseEvents(true);

%this.startImage = %this.owner.getImageMap();
%this.startFrame = %this.owner.getFrame();
}

function LevelButtonBehavior::onMouseDown(%this, %modifier, %worldPos)
{
if (!isObject(%this.clickImage))
return;

%this.owner.setImageMap(%this.clickImage, %this.clickFrame);
}

function LevelButtonBehavior::onMouseUp(%this, %modifier, %worldPos)
{
if (isObject(%this.hoverImage))
%this.owner.setImageMap(%this.hoverImage, %this.hoverFrame);
else
%this.owner.setImageMap(%this.startImage, %this.startFrame);

sceneWindow2D.schedule("1","loadLevel",expandFilename( %this.level ) );
game/data/levels/level1.t2d ;
}

function LevelButtonBehavior::onMouseEnter(%this, %modifier, %worldPos)
{
if (!isObject(%this.hoverImage))
return;

%this.owner.setImageMap(%this.hoverImage, %this.hoverFrame);
}

function LevelButtonBehavior::onMouseLeave(%this, %modifier, %worldPos)
{
%this.owner.setImageMap(%this.startImage, %this.startFrame);
}

#11 You should not just type a random level name into the "onMouseUp" function. When you attach the behavior to a static sprite (with separate frames for "hover" and "depressed"), you'll put the file name for the level into the "level" field that will appear.
