I’m sure this is simple but I have been searching on the net and max help files with no luck.
For example:
if (classOf($) == ObjectSet) then
(
messageBox "Please select just 1 object"
end script -- How??
)
(Other code here)
I know its possible with if and else statements but then the code gets ugly when theres so many conditions and your main code is indented 10 times
If you have a lot of conditions you want to test have a look for case in the help. It works a bit like else if but is a bit neater.
case classOf obj of
(
box:(some code here)
cone:(some code here)
sphere:(some code here)
default:(some code here) --if non of the above are true
)
This is how I tend to do that kind of thing.
fn validateSelection =
(
if selection.count == 0 then
(
messageBox "Nothing selected"
return false
)
else if selection.count >= 2 then
(
messageBox "Please select just one object"
return false
)
true
)
button start "Start"
on start pressed do
(
if (validateSelection()) then
(
doStuffWithSelection()
)
)

what do you actually want to exit: loop, function, or entire script?
you can’t exit , only error generate a “script interrupt” and “[size=2][font=Courier New]escapeEnable true” detect [/size][/font]the Esc[size=3][font=Times New Roman] key when your “while loop” is infinite and you want interrupt it.
You can use the “[size=2][font=Courier New]return” code like C++:[/font][/size][/size][/font][size=3]
[/size][left]
[/left]
fn main =
(
<your code>
if condition do return 0
<your code>
return 1
)
main()
because the scope of your code is inside a function, not in global scope as listener
