How to get animation played only once when target is found? For now I'm using animation.Play and Stop function on defaulttrackableeventhandler.cs script. When target is lost, 3D object dissapears, but when target is found, animation starts from beginning, but this is wrong. Animation is a growing 3D city, so what I'm trying to get is to play animation only once after first time, when marker was found. I'm stuck on this, because function animation.Play under onTrackingFound() starts animation from beginning every time when marker is founded.
