Multile animations doesnt work on more than 1 object

[swat0284]

Hello i try to run 5 animations on 5 diffrent models but i have an error:
 

Uncaught TypeError: Cannot read property 'frame' of undefined
    at i._interpolate (babylon.js:18)
    at i.animate (babylon.js:19)
    at e._animate (babylon.js:19)
    at i._animate (babylon.js:12)
    at i.render (babylon.js:12)
    at main.js:33
    at n._renderLoop (babylon.js:4)

My code is very silmpy

function CreateAnimation(index)
{	
	
	var moveAnimation = new BABYLON.Animation("moveAnimation", "position", 30, BABYLON.Animation.ANIMATIONTYPE_VECTOR3, BABYLON.Animation.ANIMATIONLOOPMODE_CYCLE); //tworzenie animacji przemieszczania sie
    var moveKeys = [];
	var moveLenght = 0;
	console.log(checkpointsPositions[index].length +"checkpoints lenght");
	for(var i = 0 ; i < checkpointsPositions[index].length ; i++)
	{
		//.toFixed(0)
    moveKeys.push({ frame: (jsonObjectResults.points[licznik].time)*30, value: (checkpointsPositions[index][i].position) });
	console.log(checkpointsPositions[index][i].position + " +++ " + (jsonObjectResults.points[licznik].time).toFixed(0)*30);
	console.log("Licznik " + licznik);
	moveLenght++;
	licznik++;
	}
	licznik++;
    moveAnimation.setKeys(moveKeys);
    players[index].animations.push(moveAnimation);
	scene.beginAnimation(players[index], 0, jsonObjectResults.points[licznik-2].time*30, true);
	
}

I start the code by createAnimation(index of mesh) and when i run it once it works but when i run it more than one it doesnt work

Hi,

I am not sure I get what you are trying to do. In each run of the for loop, you add further keys to the animation, and then you push the same object to the player in a specific index. You also don't reset the array, you simply add further objects. when you "setKeys" again, you "remove" the old keys, and then set the new ones. And, as far as I know (and this is probably the answer to the entire question) - animations cannot be shares between objects. Animation keys can be shared between animation objects, if you want to reuse. But you need an animation object per mesh.

BABYLON.Animation instances maintain state.  Running them on multiple meshes, as you have seen, does not work.  The keys are what takes up all the space though.  The array, you call moveKeys, is highly likely to work in multiple meshes

So how can i generate ultiple animation for multiple objects

Don't know if these will help or not but have a look
