Ah, in version 0.1, you had to press START after your script finish to continue.  Alot of people thought the script/DSLua was hanging.  So, I have removed the need to press START and just wait around 1.5 seconds.  If you want a delay at the end of script, you can put in this loop at the end:

Code:

while true do
  if Pads.AnyKey() then
    break
  end
  Screen.WaitForVBL()
end


Some of the new example scripts in the DSLua 0.2 scripts directory uses this trick. Smiley

its a stupid change.

how about adding in the next update something like this:
Screen.Waitshutdown(3s)
this means it waits 3sec before the script shuts down and this:
Screen.Waitshutdown(e)
e=endless

and if you say
Code:
Screen.Waitshutdown(e)

if Pads.Start() then
 Screen.Waitshutdown(3s)
end

if Pads.Start() then
 break
end

the script shuts down in 3seconds after you pressed Start

P.S. what the fuck does Screen.WaitForVBL() and VBL is?

That's an interesting idea.  I will think about it.

VBL is "Vertical Blank".  It happens everytime your DS draws a full screen.  This is useful when you do animations, so you won't get graphic glitches.  Also, it also acts as a small delay for the processor to get a chance do some other stuff.  If you don't put a small delay in a tight loop, the code may not be very responsive.
