Is there a way to delete the level and leave the grid intact?

I am thinking that you would have to make the grid part of the backdrop. Then you could add everything to it, play the level and then to a CLEAR. The backdrop would obviously stay.

but how could I get the grid to be the perfect size box?

I don't do art, but there must be a tool you could draw it in and upload it.

Another alternative is to make the obstacles be sprites, and/or clones of sprites.

eh, I might just deal with the wait, its not that long I guess..

You can tick ‘run without screen refresh’ in the custom block options and the grid generates almost instantly. c:

Since it doesn't wait i guess that would work

Ok using this method, I still get the level ‘rendering’ I wanted but it is quick. By using a broadcast at the end of the grid to activate the level instead of the custom block, the second stage is normal speed

click the “run without screen refresh”
grids as shape will go forever
