GUI clarification (Page 1 of 2)

http://www.maratis3d.org/?page_id=53 < why not just use this for now...GUIDEMO at bottom of screen.

I started rewriting MGui to be able to use it as dynamic library,
see this post : http://forum.maratis3d.com/viewtopic.php?id=723

but it's still experimental and seems to compile good on osx only (but it uses premake)
I didn't have time to check the linux and win compilation errors yet.

But, except if you need an interface with text editing and a classic GUI, as it's 2d only and doesn't use meshs,
I don't believe MGui is the best for game, it's use it to handle software GUI (like Maratis editor).

I still think that the good step would be to create a set of Behaviors to attach to entities,
a 'Button' behavior, a "Slide" behavior etc. But it sure depend of the final use.

If you want, you can try to use the new experimental MGui in c++ in your game plugin,
use the sources directly, the new version is stand-alone.

You will find everything in branches/Experimental/

Here are the headers :

You will also need tinyutf8 (one header lib) :
https://code.google.com/p/maratis/sourc … 2Ftinyutf8

To use it, create a MWindow :
- to send input events, use onKeyDown, onKeyUp etc
- use addNewWindow() to create MGuiWindow sub-windows
- call draw() in your custom game class to draw the GUI

To add an editable text with MGuiWindow :

MGuiEditText * text = guiwin->addNewEditText();
text->setPosition(MVector2(100, 100));
text->setFont(fontRef);
text->setTextSize(16);
text->setText("Hello world !");
text->setTextColor(MVector4(1, 1, 1, 1));

ps : fontRef is a font, you can get it from your current level :
MFontRef * fontRef = level->loadFont("/Library/Fonts/Arial.ttf");

Ok it took a while to compile correctly but now it works.
I see a white square which I enlarged using setScale();
I don't see the text though, even changing the color and setting up the font.
I also tried a button, but no luck, I don't see anything even after doing setText().
So I'm not sure how to actually use this.

Oh I didn't know it wanted the full path, I used local.
Now it works, thanks.

To load a texture, use "level->loadTexture" like for level->loadFont.

For the text moving with the camera, is it working if you use the fixed renderer instead of the standard renderer ?
Is yes, I know what it is but I have to modify some code.

ok, I'm modifying something in the renderer,
you'll just have to recompile maratis editor with the svn sources.

A fix (to be tested) is on svn.

you have to recompile the game.dll

Looks like if the plugin is compiled with VC 2010 it doesn't work with Maratis build with VC 2008.
Can you confirm that?

Yes.

I tried again compiling Maratis with VS2010, finished right now. I tested my game plugin and it works.
I'm puzzled though: shouldn't a user be allowed to write a plugin DLL for Maratis regardless of how it was compiled?
This is what I would expect.

BTW, I confirm that your fix works. Now I see 2D text.
Thank you.

You have to feed your MWindow with events,
we have to find a better way, but for now you can do this in your game update :

MSystemContext * system = engine->getSystemContext();
MInputContext * input = engine->getInputContext();

unsigned int width, height;
system->getScreenSize(&width, &height);

// mouse button
if(input->onKeyDown("MOUSE_BUTTON1"))
    window->onMouseButtonDown(MMOUSE_BUTTON_LEFT);

if(input->onKeyUp("MOUSE_BUTTON1"))
    window->onMouseButtonUp(MMOUSE_BUTTON_LEFT);

// and mouse move
int mx = input->getAxis("MOUSE_X")*width;
int my = input->getAxis("MOUSE_Y")*height;

window->onMouseMove(MVector2(mx, my)); // [EDIT] : sorry for the bad example

I'll start to think of a semi automatic way to send events to MWindow
