Maxscript function argument
show user profile  3joez
How do I specify a function argument?

I have this function that puts the pivot to the bottom of selected objects

fn bp =

(
$.pivot = [($.max.x+$.min.x)/2, ($.max.y+$.min.y)/2, $.min.z ]
)

I want to add an argument so that when I call bp($) it reads the current selection.

(
fn bp =

(
$.pivot = [($.max.x+$.min.x)/2, ($.max.y+$.min.y)/2, $.min.z ]
)


for ob in $ do (
convertToPoly $
polyop.setVertSelection ob #all
ob.weldThreshold = 0.001
polyop.weldVertsByThreshold ob #all
bp()
)


)

Right now it's not positioning the pivot relatively to the single objects but to the whole selection.

If I understand correctly, you want
fn bp obj = obj.pivot = [obj.center.x, obj.center.y, obj.min.z]

then the call would be
for ob in selection do(
. . .
bp ob
)


Is that it?


edit: you don't have to select the verts prior to welding them since the weld method lets you pass a vertex list (here #all).

edit2: as a more general advice, it's good practice to restore system defaults when you change them as there might be other parts of your script - or other scripts - that rely on their values. Just frame the code with a store/load:
oldThreshold = ob.weldThreshold
. . . change threshold and do stuff
ob.weldThreshold = oldThreshold

Garp, that's way more elegant than what I wrote.

(
fn bp obj =

(
obj.pivot = [ obj.center.x, obj.center.y, obj.min.z ]
)


for obj in selection do (


obj.weldThreshold = 0.001
polyop.weldVertsByThreshold obj #all
bp obj

)


)


I will take the time to restore the defaults too, as you suggested.
Thanks.
