So, I was rendering some height maps earlier. Figured I would use a no screen refresh block, but it turn out something went wrong! Apparently, the render gets “cut off” at some places while running in no screen refresh mode. So, to make sure my scripts were not at fault, I checked with screen refresh (but with turbo) and it worked fine. Are my scripts the problem or something else?

It happens because the custom no refresh block can't do all the job at once (needs more time than a screen refresh)

when green flag clicked
clear
pen up
set pen size to (2)
Gen :: custom
go to x: (-25) y: (50)
set [basic x v] to [-25]
set [count v] to [0]
repeat (240) 
  set y to (50)
  set x to (basic x)
  change x by ((count) / (100))
  No refresh :: custom
end

define No refresh
repeat (100) 
  set [prev x v] to (x position)
  set [prev y v] to (y position)
  change [count v] by (1)
  set pen shade to (50)
  pen down
  repeat (item (count) of [Noise Map v] :: list) 
    change y by (1)
    change pen shade by (2)
  end
  pen up
  set y to (prev y)
  set x to (prev x)
  change x by (-2)
  change y by (-2)
end

Hmm, thanks for the info! Still a bit confused why a simple script like that needs that much time to be executed
