Description

Hi guys,

I'm new to this forum (and scripting in general) but decided to take the plunge and learn. I'm trying to write a script that randomly scales objects between two values, using the very basic Maxscript-knowledge I have right now.

I run into two problems:
- When the rollout opens, I'd like the default values to be set to 0.9 for 'min' and 1.1 for 'max', but can't get it to work.
- When I use the current rollout, and don't change the values, the scaling goes hopelessly wrong. Even though the spinners say 0.9 by default, it seems to be using '0.0' as a default
- Is there a way to use three digits after the komma?

Thanks a lot, I'll post the code below.

Hi Swillie,
all you need is described in the help. the range property hold [min,max,val] where 'min' and 'max' define you range and the 'val' is the default value. In you case that w'd be "range:[0.9,1.1,0.9]". That's it.

And also each spinner has 'scale' property which give you a desired precision without messing with the global settings (preferences.spinnerPrecision). So here is example spinner: 

spinner spn1 "Min" pos:[15,59] width:58 height:16 range:[0.9,1.1,0.9] scale:0.01

Cheers

Hi man, thanks for helping. Unfortunately I don't quite understand

- What's with the [0.154324,10.1,0.9] and [0.121123,10.1,1.1]? I want it to range between 0.9 and 1.1, how does this apply? And why the extremely precise but seemingly random numbers?
- How do I use preferences.spinnerPrecision ? In other words, how and where do I put in into my code? Doesn't seem to work when I try it.

Many thanks for your patience, I understand that for experienced scipters these questions might be a pain :)

spinner spn1 "Min" pos:[15,59] width:58 height:16 range:[0.154324,10.1,0.9]
spinner spn2 "Max" pos:[15,78] width:58 height:16 range:[0.121123,10.1,1.1]

and

preferences.spinnerPrecision

This integer value defines the number of decimal digits displayed by spinners.
Corresponds to the Precision value in the Spinners group in Customize > Preferences > General.
