How To Move GameObjects In Fixed Path?

I have two questions in one. Yes I know only one question per question asked but it’s related to this. I’ll be sure to not only accept who’s ever answer I’m most satisfied with, but also give it a like. Anyways as you read in the title I want to know how can I move certain gameobjects in a fixed path to a certain position. For an example let’s say a gameobject is off screen, well I would like to move it across the screen all the way to the end in a diagonal movement(straight up across the screen), then destroy it so it doesn’t affect the performance or something.

Now the next question, how can I change the scale of a sprite gameobject from a script to a certain scale? It’s like the first question only re-scaling it not moving it. Well sorry for the long paragraphs it was mostly just me typing nonsense. Anyways thanks for reading.

Use iTween: Unity Asset Store - The Best Assets for Game Making
It can do everything related to moving in certain paths.

What comes to your sprite scaling, it’s not clear, if you want to scale go itself use transform.localScale Unity - Scripting API: Transform.localScale

If you want to scale sprite itself use sprite.bounds Unity - Scripting API: Sprite.bounds
