Script Help

[Anonymous]

Hello All,

I'm trying to combine 3 small pivot scripts into One, so that I can cycle threw each with one keystroke. I quite literally have ZERO experiance with MaxScript, have tried to google search, youtube, and read the information about it.. But i'm completly lost, and cant seem to get these to all work together... Can anyone possibly help me out?

(Below are the 3 scripts):

($.pivot.z = $.min.z )

Macroscript CenterPivot

($.pivot.z = $.max.z)

Honestly, I'm not even quite sure if I wrote the first and last correctly, as i get a script error when I click it with nothing selected. 😕

Thanks for any input,

Regards,

Nolan

1st and last are valid, middle would be "centerPivot $"
However, yes - all 3 will fail if there's no object currently selected, that's one good reason for not using "$" in scripts. At the very least you must ensure that the script doesn't run if nothing is selected, and at the same time account for more than 1 object being selected.

(for obj in selection do (obj.pivot.z = obj.min.z))
(for obj in selection do (centerPivot obj))
(for obj in selection do (obj.pivot.z = obj.max.z))

They will do nothing if the selection collection is empty (nothing is selected).
Or if you only want it to work when 1 object (not more or less, just 1) then

(if selection.count == 1 then (selection[1].pivot.z = selection[1].min.z))
(if selection.count == 1 then (centerPivot selection[1]) 
(if selection.count == 1 then (selection[1].pivot.z = selection[1].max.z))

As for cycling through them with a single keystroke (like the Region Selection toolbar button does) I don't know. I don't think you can create flyout toolbar buttons like that (though I could be wrong). It might be possible to script an imitation of that, but that would probably mean creating a global variable to track the current "option" and increment it when it's done. Probably easier to just create 3 scripts with a different shortcut for each.

Thanks for the Reply Steve! Much appriciated.

Regarding the cycling threw. I'm not really looking to create any UI for the script. I mainly just want to assign a keystroke to the routine. I was thinking it would look somthing like this (if it was even possible).

Set pivot to obj.Min.z, if pivot is set to obj.min.z, set to centerPivot, if set to centerPivot obj, set to obj.max.z

I guess i really just dont know the coding language to try it, and I dont really understand how to add variables like, "If X is X do X".

Ok, which version do you want? All selected or only allow it to work if there's just one?

just one object selected would be PERFECT!

Here you go 🙂

(
if selection.count == 1 then
	(
	local obj = selection[1]
	if obj.pivot.z == obj.min.z then
		obj.pivot.z = obj.max.z
	else
		if obj.pivot.z == obj.max.z then
			centerPivot obj
		else
			obj.pivot.z = obj.min.z
	)
)

DUDE!! YOU ARE MY **** HERO!!!

I've been trying to get this figured out for months! lol *facepalm*

No worries 🙂
Slight modification - insert this line at the top of the script (in the Maxscript Editor) and execute it (Ctrl+E) once. Then go to Customise > Customise User Interface > Keyboard (tab). Change the Category dropdown to ScriptTools, highlight the PivotMover and add a shortcut key. Makes life easier 🙂
