Add a new animation to the camera

https://www.babylonjs-playground.com/#3M7Q1U#58
this is my PG, when I click on the model, the chance to move to the model, so I add a buffer to camera animation, click again, let him move slowly to the target position, but is very bad, when I click on the model, the phase opportunities to move immediately to the model, and then the execution of the animation, I don’t want to make such effect, how to ensure that, after I click on the model phase opportunity through animation, slowly moving into the model of location


I just want to know that in my scenario, createAndStartAnimation, the starting point and the emphasis, what value should I get, * No matter how much I give him the parameters, I can’t get the result I want,
