Set a mesh/camera position/rotation smoothly

[3Dlove]

Hello guys =D

 

I would like to set a camera position by programmation but the camera move directly to the position, OK normal but how to do that smoothly with inertia ?

 

I do that when I click on a mesh to move the camera in front of the mesh (I used a FreeCamera).

 

It would be nice if the setTarget method has a second inertia parameter, the same for a setPosition function

 

Thanks for your help

I found something : Animation =D

var animationPlane = new BABYLON.Animation('anim', 'position.z', 30, BABYLON.Animation.ANIMATIONTYPE_FLOAT, BABYLON.Animation.ANIMATIONLOOPMODE_CONSTANT);var keys = [];  keys.push({ frame: 0, value: scene.getMeshByName(name).position.z });keys.push({ frame: 10, value: scene.getMeshByName(name).position.z-3 });keys.push({ frame: 20, value: scene.getMeshByName(name).position.z-6 });keys.push({ frame: 30, value: scene.getMeshByName(name).position.z-9 });animationPlane.setKeys(keys);plane.animations.push(animationPlane);scene.beginAnimation(plane, 0, 30, true);

I'm trying to do it with vectors

Here is the solution with vectors :

var animationPlane = new BABYLON.Animation('anim', 'position', 30, BABYLON.Animation.ANIMATIONTYPE_VECTOR3, BABYLON.Animation.ANIMATIONLOOPMODE_CONSTANT);var keys = [];  keys.push({ frame: 0, value: scene.getMeshByName(name).position });keys.push({ frame: 30, value: planeFinalVector });animationPlane.setKeys(keys);plane.animations.push(animationPlane);scene.beginAnimation(plane, 0, 30, true);

Is it possible to do the same with a camera instead of a mesh ?

 

How to remove the animation in order to free the memory ? because I use it just once and we do "plane.animations.push" ?

maybe "plane.animations = null" ??

You can do the same with a camera.position

to remove animations you just have to remove them from mesh.animations (with a splice or by setting mesh.animations = [])

OK thanks

 

For people who don't know it : in order to just play animation once without loop :

set the 4th parameter of beginAnimation to false ! (I took 20 min to find my error^^)

 

 

Is the below code a good way to free memory and play an animation juste one and delete it ?

// Animations Beginningscene.beginAnimation(plane, 0, 30, false);scene.beginAnimation(scene.activeCamera, 0, 30, false);      // Free Memoryplane.animations = [];  scene.activeCamera.animations = [];

You can use the 6th parameter to provide a callback to free memory. More info here:

OK thanks

 

I used :

 var animatableCam = scene.beginAnimation(scene.activeCamera, 0, 30, false);animatableCam.onAnimationEnd = function() {        // some code        // Free Memory        scene.activeCamera.animations = [];  };
