DzGroupNone behaviours *Solved*

Totte

Hi,

I have some issues to get a DzGroupNode created in script to behave similar (give the same results) as a DzGroupNode created using Create->New Group... and enbedding the selected node into the group. See attached image,

I suspect that the DS Action does some behind the scenes tricks (that I very much would like to do myself, to get the same behavoir. I do call invalidateBoundingBoxes() in tghe DzGroupNode after the node has been parented to it.

Thanks to Rob Whiz and also MikeD for brining clairity to this.

 In 4.x DzBox3::include() is bugged in script (it is fixed in 6.x), but translation of the C++ code to script is:

var boxWorld = new DzBox3();

var aNodes = Scene.getSelectedNodeList();
for( var i = 0, n = aNodes.length; i < n; i += 1 ){
 boxWorld.include( aNodes[i].getWSBoundingBox() );
}

var vecMax = boxWorld.max;
var vecMin = boxWorld.min;
var vecMid = vecMax.add( vecMin ).multiply( new DzVec3( 0.5, 0.5, 0.5 ) );

if( oGroupNode ){
 oGroupNode.setWSPos( new DzVec3( vecMid.x, vecMin.y, vecMid.z ) );
}

The C++ is shorter - operator functions on DzVec3
