How do I make a created object go the opposite direction

I am creating the same object every second and they are all set to move to the right a a certain speed. I am simulating the right button down on every tick as long as the direction variable I made is equal to 1 (0=not moving, 1=move to the right, 2=move left). My question is, how do I change the direction of movement of the objects that are already created? Basically when I press a button that switches the variable to 2 I need all the objects created to move left instead of just the objects that are about to spawn. Any way to do this?

I hope I understood the question correctly. It would easier to answer if you had provide a capx.

But what I understood so far, you could use: System Pick all (your objects) -> set direction=2

Then all instance variables of your objects should be set to two.

You don't even need to "pick all" the objects.

By default and in regards to how events work, simply setting the action Object - set Instance variable "direction" value to 2 in an event "on key pressed" should do the work.

This won't impact "instances to be created" since the key press is a triggered event and only applies to existing instances.

If this does not help, do post your capx as specificities of the project might get in the way somehow.

I still can't seem to get them to move the opposite direction. Here is a .capx. Obviously it would be appreciated if you didn't copy my (less than brilliant) ideas. Thanks!

Hate to bump, but can anyone help me?

I tried something and it works, but I don't know if it is exactly what you want. I changed a little bit and don't use the 8Dirction-Behavior and I have a little bit problems with wait. So I have to use a Direction 0, because if I put the wait from Direction 0 in Direction 2 it doesn't work. Maybe a more advanced programmer could say why.
