Randomly Play Animator's Animation

I am working on platform based game on Unity game engine so various obstacles contain movement and I created animation for this purpose.

I have created moving animation of obstacle from left to right and right to left side and it was working properly. It get started from 0 unit and completed at 10 units and traveling back to 0 unity place always.

In this I want to add variation, its starting point will be dynamic so one time it get spawned on 5 unit and complete rest journey of pre recorded animation, next time it spawn at 3 unit and complete rest journey up to 10 units. and then travel back.

So that game player can't predict the behaviour of obstacles otherwise its easy to predict obstacle movement. I hope you are getting me into this so provide me some suggestion.

You can use the random.range function to return a random number between (min, max)
int startingPoint = Random.Range(0, 10) this will return a random integer with between 0 and 11, as the 10 is inclusive that will be the highest possible number.

int startingPoint = Random.Range(0, 10)

If you're using an animation component you can then skip to that point in the animation clip using myAnimator.playbackTime = startingPoint

myAnimator.playbackTime = startingPoint

Official unity doc on random.range

Basically my question was about playing animation from random point - not just on moving animation but any kind of animation I want to start at random point from recorded click - I completely knew about random class and its working so my focus was on animation rather than random class.

that is what the myAnimator.playbackTime = startingPoint part is for. myAnimator will be the component your animation is on. playbackTime is the playback position in the animations timeline. say for example startingPoint is 2, myAnimator.playbackTime = startingPoint will start your animation at 2 seconds into the animation. this is what you want correct? docs.unity3d.com/ScriptReference/Animator-playbackTime.html

myAnimator.playbackTime = startingPoint

In this case it would be better to decouple your visuals animation and the randomization logic.

Make your obstacles reuse a common animation which doesn't change the position of the object (Like just sprite animation).
And then control the positioning using another script that randomly selects a distance to move.
