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

You can put your constrain in the otherwise of an overlap or collide rule. Unfortunately thats about the only way. thats one bad thing about constrains. Also can be very useful though.

If collide stop constrain.
