Problem with my Rubik's Cube groups

[loloof64]

Hello,

 

I am trying to build a Rubik's Cube (see my attemps in BabylonJs playground http://www.babylonjs.com/playground/#EQ0SF).

 

Each little cube is a mesh on its own (UnitCube builder function), so I am trying to group temporary some of them into a single Mesh, in order to rotate the group, but it does not works (into methods 

• clearGroupToRotate()
• affectWholeCubeToRotatedGroup()
• affectLayerToRotate()

of Rubik's cube class).

 

What workaround could you advise me ?

 

Regards.

Have you thought about parenting?  Make on of the 9? the parent, move it, & all the others go with it.  Nice thing about parenting is its pickup game nature.  Merging meshes sounds more difficult to undo.

Thank you for your answer.

 

Indeed, it is what I tried inside the two methods affectWholeCubeToRotatedGroup() and affectLayerToRotate() of the RubiksCube class :

• the class holds a reference to a Mesh (groupToRotate, defined in line 185), which is responsible for holding a single group of UnitCube at one time,
• when I want to "clear the group" : I simply define the property parent of the requested UnitCubes to null (line 232)
• when I want to "assign a group" : I simply define the property parent of the requested UnitCubes to link to this groupToRotate (line 239)
• and of course, when I want to rotate the group, I call the rotate() method on the groupToRotate (line 280).

But what happens, is that as soon the rotation should have taken place, the Rubik's Cube disappear from screen.

I finally found the error 

 

I was calling Mesh#rotate() with wrong parameters order.

Can you share the fixed code ?
