This is really simple I’m sure but its something I always need. I’m not a programmer so bear with me.
How do you query the number of selected objects, giving a number that can be used in a loop to run a script on each object in the selection.
I seen the getcurrentselection command and assumed this would be involved but when I tried to get info with it it gave me a lot more than just a figure.
Note that you don’t always need the number of selected object to perform a loop.
MAXScript for loops can automatically loop through object collections, assigning the next object to the loop variable instead of a number.
For example
instead of using
for i = 1 to selection.count do format “%
” selection[i].name
you can say
for o in selection do format “%
” o.name
Both will print the names of all selected objects.
Some functions and property assignments don’t even need a for loop. They are called “mappable” and can be “mapped” to object collections, performing a loop internally.
For example, instead of
for o in selection do o.xray = true
you can say
selection.xray = true
to turn on See-Through mode in all selected objects…
Mappable functions are denoted as such in the Reference.
(getCurrentSelection()).count or selection.count
thanks a lot guys. It’ll take a bit for me to try all this out, but cheers for the tips.
