i have a simple stripped down javascript, that should write some text in a window with jit.gl.text2d.

i can see the axes of jit.gl.text2d, but not the text.

in the example below i include a jit.gl.gridshape just to show, that this one works fine.

var window = new JitterObject("jit.window","thewin");

var render = new JitterObject("jit.gl.render","thewin");

tt = new JitterObject("jit.gl.gridshape","thewin");

tt.position = [Math.random()-0.5,Math.random()-0.5,0];

ss = new JitterObject("jit.gl.text2d","thewin");

ss.position = [Math.random()-0.5,Math.random()-0.5,0];

please help,

autowatch = 1;
var window = new JitterObject("jit.window","thewin");
window.depthbuffer = 1;
window.idlemouse = 1;
var render = new JitterObject("jit.gl.render","thewin");
render.ortho = 2;

tt.shape = "plane";
tt.lighting_enable = 1;

ss.text = "ertz";
ss.size = 78;

    render.erase();
    render.drawclients();
    render.swap();

Sounds like a depth buffering issue. You may way to disable depth buffeting for your text object and explicitly render after the gridshape.

and turn off depth buffering here with depth_enable = 0

but the following still does not show my text:

i had a same problem. i wish Max has more detail reference about javascript :)

you can use ss.text("ertz"); syntax instead of ss.text = "ertz".

This is actually all documented fairly clearly in the Max reference.

Javascript will, of course happily allow you to shoot yourself in the kneecap as much as you want, but that's another story.

BTW, size is another message that you're treating as an attribute in the posted code.

- Max messages are functions in Javascript

- Max attributes are attributes in Javascript (you can set and get using simple assignment)

The difference between ss.text("foobar") and (say) ss.depth_enable=0 is that text is a message to jit.gl.text2d while depth_enable is an attribute.

I have have some problem with this object too but I'm developping in Java.

I can easily code and chain jitter object and render it to a videoplane and a window.

I thought I got the logic on how it works but now when I try to instantiate this object like this :

this.jit_text2d = new JitterObject("jit.gl.text2d", this.context);    

the max console says : Could not instantiate class jit.gl.text2d

this.jit_text2d = new JitterObject("jit.gl.text2d");    
this.jit_text2d.setAttr("drawto", this.context);

because I found that for jit.gl.pix object we cannot pass the context as the second argument but we must declare it afterwards as an attribute .

But it won't work, am I missing something? is there a specific logic to the jit.gl.text2d?

If someone has a clue of what might cause this error?

ok I guess this object as well as jit.gl.text3d doesn't exist in the java world

re,
ok I guess this object as well as jit.gl.text3d doesn't exist in the java world
instead jit.gl.text does
I'll try with that then


yes use jit.gl.text @mode 2d. jit.gl.text2d is simply an alias for this.

jit.gl.text2d created with javascript not working ?
