But Explode didn't call the export function, so why did it work?

Anyway it's very interesting. But i don't understand your two last sentences.

What he said. Also, I think lamp has an export system in the project I used to test it in T3D.

I just said i didn't understand his two last sentences, which you just quoted me as an answer.

I don't see, Jeff, what you mean by you don't have to just export prefs.

I was saying that you can save any $global variable to a file, it does not have to start with $pref::

Yes, but if it starts with $pi:: is it necessary to add the export() line in the onExit function?

No, export is only used for saving variables, like saving highscore data and stuff. once again the :: means nothing, its just organization.

I know, i wanted to know if export was necessary to save the variable when you quit the game. As i can see it is.

I didn't mean to especially use the variable during MB's execution (which is not complicated), just to save its value when you quit the game.

Anyway thanks a lot, i think i've understand.

Bump. I have two questions to ask.


How can i remove the intro before the main menu? I think i have to delete or modify the function runPresentation(); but i can't find it anywhere? Is it already in a compiled file?

What's the function to repeat a function for a chosen time?

Never looked it up, but its suppost to deal with objects...just use 0, I always use zero.

If you need to schedule a method on an object, use:

%obj.schedule(time in ms, method, args);

Bump

I have another question. I would like to create a GUI which give you the list of missions in the missions folder, and you can select a mission and click on a button to play it. What is a GUI object to make this kind of list ? And what are the methods i'll have to use for it ? Thanks.

BTW is there a reference with the list of GUI objects and their methods in torquescript?

you can google the torqueScript reference manual.

use a guiTextListCtrl()

to add a row, do:

nameOfObject.addRow(nameOfObject.rowCount(),text to be added);

to get a row, use an index, starting with row 0

%row = nameOfObject.getRowTextById(nameOfObject.getSelectedId());

to clear a list, use this:

nameOfObject.clear();

any further questions just ask, i'll be happy to assist!

When i want to add a row:

What object is the second argument and with what i want to do, the text to be added is a mission name?

Convert your song to a .ogg file (if it isn't already) and put it in your marble/data/sound/music directory (if it's in MBP, it's platinum instead of marble). Then in your level, add a dynamics field and call it music. For the value, use the name of your song (with the .ogg extension).

that is the function ^

If you want to just load another one while playing one, do

loadMission(marble/data/missions/beginner/bla.mis);

Been a while since the last post, but I do have a question.

For binding functions to keys, how do you prevent running the function multiple times when the key is held down? I want to make it so that:
1 press = 1 function execution

EDIT: Apparently the reason the function is executing twice is because the function runs once when the key is pressed and once more when the key is released. How do I just make it run once and ignore when the key is released?

Not entirely sure if there is a cleaner way of doing this, I'll let Jeff provide input as well.

Because of the nature of the key binding in this engine, it may not be possible to tell it to fire one function per button press. However, we can implement some hackish code;

Setup a global variable, something like $functionname_Toggled = False

Now enclose everything in your function with an if-statement that requires functionname_Toggled to be false. Additionally, inside of your if-statement, near the end, insert $functionname_Toggled = True and a schedule to set $functionname_Toggled = False a couple seconds later. This will force the function to run once and not allow itself to be executed until the schedule re-flags the Boolean to be false once more.

Hopefully this helps,
