[Closed] Dynamic Rollout

What you do is create a rollout normally and then just put it into quotation marks. (Using “” for literal quotes, \ for slash etc.) Just treating it like a string.

bob = “” as stringstream

is really just a fancy string.

then you add stuff to it.

format “jim = “%”
” “Timmy” to:bob

(” is a literal ” and
literal “new line”. The % means put a variable in this place.)

The output of that would be the equivalent to:

jim = “Timmy”

then you execute your string when the code is done:

execute bob. And it’s like using a “filein” script only from a string.

This’ll now define a variable.

If you want a rollout you create the rollout say

for i = 1 to 100 format “Rollout Box%” i to:AStringStream
etc etc…

you would now have 100 rollouts whose name formatting you know.

AddSS = “” as stringstream
for i = 1 to 100 do
(
format “AddSubRollout Rollout Box%
” i to:AddSS
)
execute AddSS

It’s just creating code dynamically. Nothing particularly fancy. So the easiest way is to write the code once. And then write a function which batch “writes” code.

ok, thx for ur explanations

But why is he using 5 time i in his script

 ") i i i i i to:codestream
  format "AddSubRollout PFManagerRollout.op BirthOp%" i to:codestream

what does it mean?

because between the quotes ( format ” … ” ) there are 5 ‘%’ symbols, and every ‘i’ comes in place (e.g. substitutes) one of those ‘%’ .

btw. you can use the built-in RolloutCreator struct to generate dynamic rollouts. Do a quick search in the reference

i know the the rolloutcreator.

but i think this way is better

format "% % was an olympic % contestant in the % olympics." FirstName LastName Sport Year to:StringStreamVar

The % are like madlibs.

it’s working fine.

Thx to all of u for ur help.

Btw, if i change this

Rollout test

to

global te = test	......   ("Rollout % ........ ") te ... to codestream

I got an error message like this one:

>> MAXScript Rollout Handler Exception: -- Cannot assign to read-only variable: undefined <<
  

because i really would like to use the % for the rollout name

The problem is you’re trying to call your rollout “Undefined”

Global testRollout = test

format (“Rollout % …) “test” to:codestream

Test needs to be a string not a variable.

The advantage of this is you can do something like:

 for o in objects do 
(
   format ("Rollout %") o.name to:stringstream
)

i m so stupid sometimes. :banghead:

thx a lot

Hehe the only reason why I know the solution to that error message so easily is because I see it so often.

I actually happen to be rewriting the script that my example was based on right now… I wish I had time to go back and rewrite the generic example. I found some much better ways of handling the rollout spinner.
