Re: does the clamp function in MEL have an equivalent in XSI expressions?

Adam, FYI:

 

The only equivalents I know of are the Clamp and ClampInPlace methods but they are for vectors. Nothing for scalars AFAIK.

 

Expressions may be quick to set in place but their syntax and connection with the environment are a bit outdated if you ask me...

Hey everyone.. happy 1st of October!

 

I was looking through the _expression_ docs, and was hoping to come across some equivalent _expression_ as MEL's clamp

 

where in the example clamp(0,10,objectValue)

 

the _expression_ sets 0 as min, 10 as max, and if the value is anywhere in between passes the objects normal value..

 

So far all I've found is to set nested conditions as follows:

 

cond( slider.kine.local.posy <  0, 0, cond( slider.kine.local.posy > 10, 10, slider.kine.local.posy ) )

I have no problem setting up conditions as such, but just thought that the clamp was a more elegant solution, and saves a lot of typing and visual confusion when setting up more complex interaction.

Would scripted operators be the way to go here?

Thanks for any additional insight
