Spawning Interiors During Runtime...

by Welias D. Willie II · in Torque Game Engine · 11/27/2004 (1:24 pm) · 6 replies

I have searched the forums, reviewed Ken's book and I am sure it is something simple that I am missing, however, can someone tell me why this code causes my torque to crash...

function serverCmdduplicateObject(%client)
{
	%obj = %client.getSelectedObj();
	%pos = %obj.getTransform();

	%name = %obj.interiorFile;

	%ax = getWord(%pos,0);
	%ay = getWord(%pos,1);
	%az = getWord(%pos,2);

	%aa = getWord(%pos,3);
	%ab = getWord(%pos,4);
	%ac = getWord(%pos,5);
	%ad = getWord(%pos,6);

	%az += 5.0;

                // setting %obj to the new Interior:
	%obj = new InteriorInstance()
   	{
                	position = %ax SPC %ay SPC %az;
                	rotation = %aa SPC %ab SPC %ac SPC %ad;
                	scale = "1 1 1";
                	interiorFile = %name;
                	showTerrainInside = "0";
   	};
}

I have used echo() on every step and it seems to work all the way to setting %obj = new Interior Instance() as I get a new Object ID number in that variable. That is the moment it crashes.

I have removed the position and rotation settings and defaulted them to position = "0 0 0"; and rotation = "1 0 0 0"; this seems to work BUT no object appears in the mission and if I use the console to adjust the position manually of the new object (pulling the id from %obj) it crashes. The object does not appear in the World Editor tree either.

By the way, %client.getSelectedObj(); works perfectly in my other functions. This script is an attempt at copying an existing object and placing it in the mission just above the original object.

I might be waaay off, but where do you have the DIF file defined? Are you sure it's the correct path?

Have you really made sure the GetWord part is working and giving the expected values? Try echoing %obj.position and &obj.rotation when it has been created or when you want to create it.

Edit: Nevermind the latter, I didn't think when I read the code.

Yes, I have confirmed that the path is correct. I defined it in %name....

%obj = %client.getSelectedObject(); // usually returns 1414 (a valid DIF object currently visible in the mission)
%pos = %obj.getTransform(); // works great
%name = %obj.interiorFile; // works great - gives me the path to the DIF of object 1414

Like I said, I pulled out all the getWords and simply did this:

%obj = new InteriorInstance()      
{                   
     position = "0 0 0";
     rotation = "0 0 0";
     scale = "1 1 1";                   
     interiorFile = %name;  // I confirmed the path is correct
     showTerrainInside = "0";      
};

For good measure I even added this after the above code:

MissionGroup.add(%obj);

I can use the console and view the tree(); and the object appears in the following location:

xxxx: ServerGroup - SimGroup
|__ xxxx: MissionGroup - SimGroup
|__ xxxx: InteriorInstance

When I view the object I just inserted into the mission and try to change the location by copy/paste of another items location (that is visible in the mission) and when I click "apply", torque crashes hard.

InteriorInstance is a sub group of MissionGroup (formatting didn't work above)

Actually I found an error in my first post, however, it has not corrected the problem.

This: 
rotation = %aa SPC %ab SPC %ac SPC %ad;

or when I just hard coded it and dropped the use of getWord();

rotation = "0 1 0 0";

should be:

rotation = "0 0 0";

This fix allows the object to actually be placed in the tree (per my post just above) but when I try to setTransform either manually or in the editor Torque crashes.

I did some more searching on the forums and founda solution to the error I was having here. For the record, I stated that rotation should only have 3 numbers, when in fact it should be 4 numbers (quarternion rotation as normally required throughout torque).

For future reference, if anyone is dynamically loading DIF objects here is the fix (yes it requires a C mod):

What forum is that thread in? First one I found that I didn't have permissions for :(

Sorry, I posted the link wrong - it was adding "
" to the end of the link which would of course make qt=19877
instead of the required resource of qt=19877 - I corrected the link in the post above.

or just copy this:
