How do I spawn object at specific Y but random X

How do I set an object to spawn at a random X but a specific Y after an event?Also,I want that object to spawn after a certain time when that event has happened.

You mean something like this?

System create object at x = random(4,25) y = 200

As you can see X is inside a random range and Y is constant..

If you want to create the object after a certain time you could use a wait action in a triggered event or use timer behaviour for it..
