multiple object instances with javascript

foobert — Thu, 17 Nov 2011 10:16:04 +0000

is there a way to actually create an on “bang” without deleting the other instances? meaning: can i create more than one object with javascript?
i tried this javascript code, but it replaces the previously drawn object with a new one.
any ideas?

function bang()
{

// generate a random text
var text = “”;
var possible = “ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789″;
for( var i=0; i < 5; i++ ) text += possible.charAt(Math.floor(Math.random() * possible.length));
var randomnumber=Math.floor(Math.random()*999999);

var mywidget[randomnumber] = new JitterObject(“jit.gl.gridshape”,”jgm2″);
mywidget[randomnumber].shape = “cube”;
mywidget[randomnumber].lighting_enable = 1;
mywidget[randomnumber].smooth_shading = 1;
mywidget[randomnumber].scale = [6,6,6];
mywidget[randomnumber].color = [1,1,1,0.5] ;
mywidget[randomnumber].blend_enable = 1;
mywidget[randomnumber].position = [1,1,1];
mywidget[randomnumber].name = text;

mywidget[randomnumber].lighting_enable=1;
mywidget[randomnumber].blend_enable=1;
mywidget[randomnumber].smooth_shading=1;
mywidget[randomnumber].depth_enable=1;
mywidget[randomnumber].material=”mtl”;
mywidget[randomnumber].cull_face=1;

var x[randomnumber]= new JitterObject(“jit.phys.body”);
x[randomnumber].shape=”cube”;
x[randomnumber].targetname = text;
x[randomnumber].scale = [6,6,6];
x[randomnumber].worldname =”foobert”;
}

*bump*
is this really not possible with max6?

i think your javascript is not correct.
shouldn’t you be declaring your arrays like this?
var mywidget = new Array();
mywidget[randomnumber] = new JitterObject
….

How about this? I can’t see what your code is doing without the rest of the patch but I think this should do what you want :)

var mywidget = new Array();
var x= new Array();

function bang()
{
	// generate a random text
	var text = "";
	var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
	for( var i=0; i < 5; i++ ) text += possible.charAt(Math.floor(Math.random() * possible.length));
	var randomnumber=Math.floor(Math.random()*999999);

	var widget = new JitterObject("jit.gl.gridshape","jgm2");
	widget.shape = "cube";
	widget.lighting_enable = 1;
	widget.smooth_shading = 1;
	widget.scale = [6,6,6];
	widget.color = [1,1,1,0.5] ;
	widget.blend_enable = 1;
	widget.position = [1,1,1];
	widget.name = text;

	widget.lighting_enable=1;
	widget.blend_enable=1;
	widget.smooth_shading=1;
	widget.depth_enable=1;
	widget.material="mtl";
	widget.cull_face=1;

	var xt= new JitterObject("jit.phys.body");
	xt.shape="cube";
	xt.targetname = text;
	xt.scale = [6,6,6];
	xt.worldname ="foobert";

	// adds the newly created objects to the ends of the arrays
	mywidget.push(widget);
	x.push(xt);

	// removes the object at the start of the arrays if outside of your 'randomnumber' limit
	if (mywidget.length > 999999)
		{
			mywiget.shift();
			x.shift();			// assuming that these arrays are only altered here it is fine to remove the elements from this one in the same block
		}
}
