Dynamic Rollout

[thatoneguy]

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 = \"%\"\n" "Timmy" to:bob

(\" is a literal " and \n 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%\n" 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?

[xenry]

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

[thatoneguy]

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

The % are like madlibs.

[holycause]

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

[thatoneguy]

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

[thatoneguy]

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

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.
