Where shall I put the change attribute to false?

if that still causes you a problem then it seems there is an issue with the attribute turning on - and make sure you turn the attribute back off

Instead of a timer for your back up put the interpolate into the otherwise section and make your attribute go back to false with a timer or some other event.

add a change attribute to false as well

push in a starting direction with the accelerate attribute with a direction which sends it onto the main playing area. After it's moved onscreen, you could have it spawn the immovable walls. Then jus

when attribute is true

Make a self attribute - call it 'sound'

Yes you can do it as mangaroo said by putting the attribute of the first actor and the second actor Physics>restitution to 0 . If you need a little bounce when collide use 0.3 or 0.5 in one

You could use a "When Object collides; constrain to behavior"

Well to go back to 0 you would simply do a change attribute to 0.

I created a demo called "fake constrain"

When exp = 21 Change attribute lvl to +1 and change attribute exp to exp-20

If you use the change attribute in a timer (every 0.00000001 sec change X and Y) it will still have collision.

yeah, that's exactly what I just did, after I noticed I didn't need the rule after the timer to see if the attribute is stil "blah". I just made the run to completion box unchecked.

When attribute is bla:

down a slider. Im guessing you utilize a real attribute and -+ it by that? Any help appreciated!

Tried that now, it worked quite well. That made the thing I wanted to happend, happen instantly when the attribute became "blah". And I only want it to happend if the attribute is bl

if attribute = ??

What do i do if I want something to happend if an attribute is equal to "bla bla" for 2 seconds or more?

I'm toying around with some shooter elements and I'm having a problem getting the walls to show destruction at the location at which they are shot by a gun. (When the bullet hits a wall, I'd like to
