[SOLVED]moving skel obj

Hi ,
i have created an animated skel from an object (the object have animation - open door) , how can i move it in the world ?
i tried :

Code:

door = ObjectPtr(UID(3856963616, 3268566013, 2296428730, 1785660301));

   skel.create(door->mesh()->skeleton(), 1.0);

   door->mesh()->move(Vec(2.0,0,0));

   skel.move(Vec(2.0,0,0));

but this animates the door wrong (it rotates around wrong vector), its like the bones haven't really moved (attached image explains) .
if i don't move it , it plays fine

don't move mesh or skeleton.

Instead call animated_skel.updateMatrix(here set custom draw matrix);

AnimatedSkeleton& updateMatrix (C Matrix &body_matrix=MatrixIdentity ); // update 'AnimSkelBone' bones 'matrix' according to bones 'orn rot pos scale' and 'body_matrix', this should be called after animating and applying manual modifications, 'body_matrix' must be normalized, this method also sets skeleton points according to bone matrixes

sorry maybe i wasn't clear , by move i meant to create the obj(skel) itself at a certain position not 0,0,0 .
because :

Code:

skel.create(door->mesh()->skeleton(), 1.0);

creates it at 0,0,0 and i wanted it at other location so i asked if it can be moved .

i tired :

Code:

skel.updateMatrix(Matrix().move(Vec(2.0,0,0)).normalize());

but nothing happened

Hi,

Default Matrix() constructor does not initialize the matrix to identity, so when you call 'move', you adjust matrix that has undefined values.

You can do this though:

Matrix().move(..) ->
Matrix().setPos(..)

replace 'move' with 'setPos' which does initialize the entire matrix.

You can try doing this also on the tutorial:
Apps\10 - Animation\01 - Animation
