How to randomly alternate an actor´s position between three predefined spots on the Y axis?

I´m trying to create a game pattern in which the actor randomly appears on one of three possible positions every five seconds...any suggestions. Thanks a lot.

Just to Clarify, Are you spawning an actor at one of 3 possible positions or are you moving an actor to one of 3 random positions?

The process I would use would be similar for both.


**Part 1**
You would need to create an "real" attribute. Eg .Call it Actor_Y_Location.

This attribute would have a number between 1-3

**Part 2**
Now, lets say your actor is spawning.

Your actor would need a few "if statements". It would be as follows

If "Actor_Y_Location" is equal to 1;

Change Actor.Location.Y to 50

If "Actor_Y_Location" is equal to 2;

Change Actor.Location.Y to 100

If "Actor_Y_Location" is equal to 3;

Change Actor.Location.Y to 200


**Part3**
Now, add a "change attribute" into the actor so every time the actor is spawned the Actor_Y_Location will change

Eg. Change Attribute "Actor_Y_Location" to Random(1,3)

Then add a timer that says "after 5 seconds" spawn "actor".

The GSTimer example is probably best for maintaining performance.

Hope this Helps.

@applucinate Then you can use Interpolate instead of Change Attribute to make it scroll.

Hi Ben, thanks a lot for your insights and ideas. I´m intending to use this actor as an scrolling obstacle to be avoid by the main character.
