What do I do wrong? (wait in a double "for" loop)

Hello.

I thought this should work fine, and I tried many combinations, different iterations, but it always creates only first block. Without "wait" it creates a nice "wall" from bricks. With time delay only one.

Thank you for any help.

If you use "wait" in a loop, then by the time the next action has run the loop has finished, so the loopindex expression won't work.

Thank you Ashley.

In that case, what is the method for running a loop like that, with a delay each step?

It would be a lot easier to either wait, then run the entire loop; or create all the objects but hidden (e.g. make them invisible), then wait after the loop, then show them. Basically wait before or after the entire loop, but not during it.

I would use the Fade behavior. Create all the brick_stop objects in the loop the way you have it, but replace the Wait action with setting the "fade in time" property. (obviously, set the fade out time to 0).

Another way to do it would be to set a global flag that would trigger creating one row of bricks every x seconds, until the board is full.

Thats both good ideas.

Thank you Ashley and AllanR! :-)
