Moving walls

So I have a hallway that I would like to be able to send walls down. Each wall would be different.

so this situation is something like

------------------------------------------------

                        <-|        <-|

           <-|          <-|

           <-|                     <-|

------------------------------------------------

I want the walls to keep moving until they hit the end of the corridor then they will be destroyed. The player will be trying to jump/duck to avoid being pushed down the hallway.

What would be a good way to set this up? Spawn each block individually and give it a velocity and set up an event where when it touches the back wall it is destroyed? Seems like this would be a huge hassle.

Anyone have a better solution?

Don't think of the walls as walls.

Think of them as Bullets and use the bullet behavior on them.

Yup, give them the bullet behavior set the speed.

You can put up a sprite wall and just set it to invisible, then check for the collision to that as well.

Bullet behavior like RangerJim and ArcadEd suggested.

Or do

+For Each MovingWall
-> Set MovingWall.X = MovingWall.X - (pixels per second) * dt

+MovingWall On Collision With SolidObject
-> Destroy MovingWall

I think the bullet behavior will work great! Thanks guys!
