Couple of maxscript questions

jeremiah_bigley

noob at this stuff... and was wondering if someone could answer a couple of things for me. I searched... problem is if you don't know what you are searching for it is hard to find.

What is a good way to stop a script without a message. Essentially a "do nothing" function. I am trying to make a for loop and whenever it can't find a specific modifier on the stack... it gives an error and stops. I would like for it to skip the object and go to the next if that modifier doesn't exist.



Next question is...
Why doesn't this work?

if variable = 50 then(

this works...

if variable > 50 then(

Any help would be greatly appreciated.

Because in programming usually = means that variable holds value after = sign. You should use '=='.

Sorry don't know the professional words for those in english. I hope you know what I mean ;p

jeremiah_bigley

that makes perfect sense! Thank you so much!

Anyone else on the do nothing function?

passerby

not sure what you mean by do nothing function?

if you want it to not error out just use some if and else statements to check for the existence of the modifiers first.

like IF modifer exists do stuff, ELSE print warning and move on.

and like MrOneTwo said in almost all languages = is generally for setting a value or variable, and == compares.

Not an expert on maxscript but I think your looking for the continue statement which skips the statements in a for,while or do loop and goes to the next iteration.

you can also use
"where" in your for loop, acts basically as a "if ... continue" inside

example:

for i = 1 to 10 where i > 5 do
(
    print "neat"
)

or on parsing arrays

for my_item in my_array where my_item.something_true() do
(
    print "neat"
)

it also works on while as well
