Help with Spawn/Create and movement

Ok, i dont get it some of the things in this engine are very strange.

Let say i want to make an AI move from top to bottom. Since the object is already added to the layout, i can go with:

Set Position (x,y)

Then Set X,Y self.x/y + 100 * dt

If i destroy it outside the layout, i wont be able to use this object later. So i must use clones or learn to use Create or Spawn.

When i use Create, it spawns continuously (why it should do this, i dont get it) the correct function could be Create X or Infinite of this object vs cords...Its like this function was made only for bullets...

So whats the correct loop to create a single object, or two..?

On Condition - Create a object at specific coordonates

Do something with the object

So far i tried:

Trigger Once : Create object

Every Tick: Move

Object Y > X : Destroy

But somehow it spawns 2 objects.

Thanks

Well i figured it out, not sure if this is the correct way, but anyway:

System Trigger Once: Create Object

Every Tick: Move

Other things

Note: If we dont isolate Every Tick: it will move all object with that name at anytime are spawned.

If you have more advanced or better example, please share:P
