Playing multiple animations

[Gugis]

Does babylon support playing multiple animations for one mesh? For example torso bones is playing attack animation and legs walk animation

[GameMonetize]

In this case the animation will be for the bones

[GameMonetize]

But sorry about my non-response: yes you can

But sorry about my non-response: yes you can

Maybe my question is not correct   I dont know how this term is called, but i guess I am looking for animations blending.

[GameMonetize]

If you are using bones the blending is automatic 

[Gugis]

If you are using bones the blending is automatic 

scene.beginAnimation(skeleton, 0, 29, true, 1.0);scene.beginAnimation(skeleton, 30, 59, true, 1.0); 

So this should play both animations?

[GameMonetize]

yes but you cannot specify in this case which part of the skeleton is animated

 

I suggest doing the same but at bones level

Sorry, I don't get it 

[GameMonetize]

Skeletons contains a collection of bones:

skeleton.bones

 

you can launch animation on each bone if you want

I have tried to play multiple animations at the same time, but blending doesn't work: http://jsfiddle.net/kolar/gPt7U/3/

Is it possible to set each animation a different weight?

The value start and end are some %. When your end has 11 means 11% of all of the animations available in models.

 

var totalFrame = skeletons[0]._scene._activeSkeletons.data.length; scene.beginAnimation(skeletons[0], 100 * 0/totalFrame, 100 * 11 /totalFrame, true, vitesse);

Wonderful what you can learn quite by accident from some of these threads.

 

1.

 

you can launch animation on each bone if you want

 

Works like a charm - and just seems to have solved a problem I was having  

myScene.beginAnimation(mySkeleton.bones[4], 90, 110, false, 1, function(){...});

2. From the jsfiddle posted by kolar above, I may have found out two things:

BABYLON.SceneLoader.ImportMesh(null, "https://dl.dropboxusercontent.com/u/12395133/", "bieber.babylon", scene, function (newMeshes, particleSystems, skeletons) {    var chlop = newMeshes[0];    scene.beginAnimation(skeletons[0], 1, 11, true, 1.0);    chlop.position.x = -1;});

a. I can use my dropbox to demo files -though not tried it yet.

 

b. the ImportMesh can return "skeletons" - all the code I have seen just had "function(newMeshes, particleSystems)".

 

 

cheers, gryff

It's not true in my example. I used animation that has 30 frames (you can check it in .babylon file) so   

scene.beginAnimation(skeletons[0], 0, 30, true, 1);

should play only ~10 frames, but it plays whole animation. See: http://jsfiddle.net/kolar/gPt7U/4/

[gryff]

Well if I was trying to play only 10 frames of a 30 frame animation then:

 

I used animation that has 30 frames (you can check it in .babylon file) so 

   scene.beginAnimation(skeletons[0], 0, 30, true, 1); 

should play only ~10 frames, but it plays whole animation.

 

I would change the "30" to "10" -  as you are telling it to play 30 frames with that code.

scene.beginAnimation(skeletons[0], 0, 100, true, 1);
 
Will play the animation of 30 frames (100 = 100%)

 

scene.beginAnimation(skeletons[0], 0, 11, true, 1);

 

play 11% available in skeletal animation

Dad72 see: http://jsfiddle.net/kolar/gPt7U/4/ , I set (from=0, to=100), (from=0, to=50) and (from=0, to=30) and in all cases it shows all keyframes, not 30%, 50% and 100% of them.

[Dad72]

So there is a bug.

 

I just wanted reported that they are %, because everyone does not know that 30 is not 30 frame, but 30%. unless this change is Deltakosh

 

Edit: I also think that if there is less than 100 frame, it is not % but the frames is calculated. (This is the impression I)

I know this is a pretty old thread, but I was trying to look up some information on scene.beginAnimation and came across this via a search, so wanted to make sure this was not left hanging (almost two years, but hey why not).

 

As far as a I can tell, from and to are the specific frames (at least when exporting with Blender), not percentages (BabylonJS v2.2)

 

Also seems to be confirmed here: http://doc.babylonjs.com/tutorials/07._Animations#parameters-for-scenebeginanimation

[Dad72]

Yes, there is a time when it was 'percentages' but now it is by 'keyframes'. but this has not always been the case.

[GameMonetize]

They were not really percentage (As far as I can remember) but frames. Obviously if last frame == 100 (which was was the previous version of exporters produced), then it looks like percentage
