Determining the tiles next to a specific position

by Bryan Zarnett · in Torque Game Builder · 08/14/2009 (8:27 pm) · 1 replies

I'm trying to create an "examine" function that based on the characters position, I want to go through all the tiles at the "next" position and determine: (1) if the examinableObject class is associated to the tile and then run the associated functions.

I can get the direction the player is facing as well as their current location.

What I am having trouble with is determining how to retrieve the tiles (image map tile) in the space.

Is the "pickTile" operation what I should use? $pickedtile = XXX.pickTile(33.750,-26.250);

If so, once I have the tile, I assume I can just call $pickedtile.Class to determine what the class is?

Any thoughts or help on this would be appreciated.

Am I even on the right track?

What should "XXX" be for pickTile if that is what I should use?

Thanks for any help.

I think I figured out what I need to do. The snippet of code is below. It works just fine but it seems to be called twice -- the results are printed twice to the console. Any idea why? I have this operation mapped to the keyboard (X) in the test and hard code the world position to make sure it was working.

Thoughts on why I would see double?

$thescenegraph = sceneWindow2D.getSceneGraph();
	
	%objList = $thescenegraph.pickPoint(%worldPos);  
	%objCount = getWordCount(%objList);
	
	%hasBeenExamined = false;
		
	for(%i=0;%i<%objCount;%i++)  
	{  
		%obj = getWord(%objList, %i);
		if(%obj.getClassName() $= "t2dStaticSprite")
		{
			// See if the particular object is associated to our viewable class
			if(%obj.Class $= "examinableObject")
			{
				%obj.examine("x");
				%hasBeenExamined = true;
			}
		}
	}
	
	if(%hasBeenExamined == false)
	{
		echo("Nothing to see here");
	}
