Creating a variable inside of a rollout

Submitted by Mackinder on Thu, 2011-05-26 03:59

Hey folks, I'm working on a small script and running into an annoying problem. Essentially when the user clicks a button, on the "pressed do" part of the roll out I want to create a variable, (such as "variableName = spinnerUserChanges.value") to then use multiple times during the next few lines (rather than constantly having to write "(spinnerUserChanges.value)".

But when I do this and try to run it constantly faults at that line.

I don't understand why this happens... is there a specific way you have to define variables while working with roll outs?

Much thanks!

Actually, scratch that, it

Actually, scratch that, it was because I wasn't setting brackets around the code... I had just one line of code so it worked fine, the second line then messed it up.

That always trips me up, silly mistake.

Thank you again.

Ah! I understand now that I

Ah! I understand now that I wasn't declaring it as either local or global... although I don't understand why I need to for a roll-out... to be honest I don't grasp why or when locals and globals need to be set.

Thank you though, you've saved me from a serious headache.

should not been a problem

Variant 1: store the value as local visible to
the whole rollout using spinner-handle:

rollout ro1 "..."
(
	local spVal = 0
 
	spinner s1 "" range:[-100,100,0]
	button b1 "..."
 
	on s1 changed val do (spVal = s1.value)
 
	on b1 pressed do (print spVal)
)

or Variant 2: make it visible to the button only:

rollout ro1 "..."
(
	spinner s1 "" range:[-100,100,0]
	button b1 "..."
 
	on b1 pressed do
	(
		local spVal = 0
		print spVal
	)
)
