[Closed] Loop controled by multiple variables

Feb 28, 2009 12:24 am

Hi all.

I want to do a loop that is controlled by multiple variables, Example:



rollout vari "variable test" width:150 height:400
(

	spinner var_a "Variable A" range:[0,10,0] type:#integer pos:[60,10] width:60
	spinner var_b "Variable B" range:[0,10,0] type:#integer pos:[60,30] width:60
	button tess "Test" pos:[5,50] width:100
	
	
	on var_a changed val do (
	
		print var_a.value as String
	
	)
	
	on var_b changed val do (
	
		print var_b.value as String

	
	)

	on tess pressed do (
		
	)
	
	
	
	
)

varfloater = newRolloutFloater "Variable Test" 150 120
addRollout vari varfloater

I want that when i press the button i can saw the result of the addition of the two values of the spinners until i arrive to the maximun values of the two spinners, then print a message

I mean if i have in an spinner a value of 2 and in the other a value of 3 the results in the output must be:

0+0 =0
1+1 =2
2+2 =4
2+3 =5

and then the printed message: “we have arrived”



0
2
4
5
"we have arrived"

Thanks

The amin and amax functions are ideal for these kinds of things. Here’s an example:

on tess pressed do
(
	-- get the highest value of both spinners
	-- this will be the end point of our loop
	local loopEnd = amax var_a.value var_b.value
	
	for i = 0 to loopEnd do
	(
		-- get the value for both spinners. the amin function
		-- makes sure the result does not exceed the spinner's value
		local val_a = amin i var_a.value
		local val_b = amin i var_b.value
		
		-- print the result
		format "% + % = %
" val_a val_b (val_a + val_b)
	)
)

Hope this helps,
