Maxscript listener assistance
Hi there, that's great that you're learing MAXScript. Not everything gets picked up by the Macrorecorder, so you have to start digging through the MAXScript help to figure out what's possible and how to do it. For your script, see if this gets you started:
t = teapot() convertto t editable_poly select t -- select the node q = Quadify_Mesh() -- create a Quadrify modifier addModifier t q -- add the modifier to our node u = UVWMap() -- create a UVWMap modifier u.realWorldMapSize = false -- same as unchecking "Real World Map Size" checkbox addmodifier t u -- add it to the node mat = scenematerials["stainless"] -- find the scene material named "stainless" -- note: this must exist on an item in the scene t.material=mat -- apply the material to the node
My script creates a node and selects it, yours would start with something like:
myNode = $
Where $ gets the selected node.
Hope that helps,

Hi there, so I think you're getting close. I think you have 2 options for dealing with the selection:
1) Assume that an object is selected before you run the script. You can verify this when you get the node, and exit with a message if you don't have something selected. This would look something like:
if selection.count != 1 then (print "Please select one object and run again.") else ( myNode = $ -- etc )
2) Attach a callback that detects when nodes are selected and runs when only one is selected. You are getting into more advanced territory here. This would look something like:
fn doSomeStuff =
(
if selection.count == 1 then (
myNode = $
print myNode
callbacks.removeScripts #selectionSetChanged id:#doStuff
-- now do some stuff
)
else print "Select one object please"
)
callbacks.addScript #selectionSetChanged "doSomeStuff()" id:#doStuff
Let me have a look at why the UVW map options aren't being set.

Huh, I can't reproduce what you're seeing with the UVW Map modifier. The mapping isn't box because we don't set it in the script. In this version I set it, and it looks ok. Are you seeing any errors in your listener when you run this script?
t = box() convertto t editable_poly select t -- select the node q = Quadify_Mesh() -- create a Quadrify modifier addModifier t q -- add the modifier to our node u = UVWMap() -- create a UVWMap modifier u.realWorldMapSize = false -- same as unchecking "Real World Map Size" checkbox u.maptype = 4 -- set to box addmodifier t u -- add it to the node mat = scenematerials["stainless"] -- find the scene material named "stainless" -- note: this must exist on an item in the scene t.material=mat -- apply the material to the node

no errors. it it checked the box this time. It did not un-check real-world map size however.
$Box:Box002 @ [0.000000,0.000000,0.000000]
$Editable_Poly:Box002 @ [0.000000,0.000000,0.000000]
OK
Quadify_Mesh:Quadify Mesh
OK
Uvwmap:UVW Map
false
4
OK
stainless:Standard
stainless:Standard
So the != and == and = can be confusing when you're first getting into scripting / programming.
! is not, so != is "not equal". Similarly, == is "is equal". Finally a single = is assignment, so x="hi" assigns the string "hi" to variable x.
In MAXScript, $ will hold the currently selected node or nodes. You can check how many things are selected by looking at selection.count. In our example, we only run if selection.count is 1, otherwise we print a message.
Once you pick up little things like this, the learning curve gets less steep. BTW these concepts are not just for MAXScript, most scripting languages have similar syntax.
Hope this helps,

Thanks @istan. I am starting to discover that. Too bad I don't already know some of the other languages. 
Hi, we don't really have a "quick reference" for MAXScript, but you might find interesting the "Learning MAXScript" section, which can be read straight through as an introductory tutorial, and will help you get started:

Can someone please tell me what the script syntax would be for this? Nothing shows up in MaxScript listener. Also it gives me lower poly count then quadrify mesh will.
