Update A with custom parameter

jc4d — Fri, 10 Jun 2022 05:23:16 GMT

Hello,

I have an object with a custom values for the width.

When I place the object, the value that shows in the toolbar is 1000 no matter what is the right width of the object. Therefore, my question is if it is possible to update that value in the toolbar to shoe the real width of the object?

Paremeters:

VALUES "mod_width" range [0.3, 2.0] Step 1, 0.005

Master:

A = mod_width

But didn't work

Instead of using 'mod_width', you could just have used 'A'.

Or you now need to say...

A = mod_width PARAMETERS A = A

The first line sets the value for 'A' that the scripts will use, but the second line sets the parameter that the user sees.

But that is not the end of it.

If the user now adjusts 'A', nothing will happen to the width - because you are not changing 'mod_width'.

You could ...

LOCK "A"

So the user can see 'A' but not change it.

That is why it is best to just use 'A' instead of 'mod_width'.

VALUES "A" range [0.3, 2.0] Step 1, 0.005

Anywhere else in your scripts that uses 'mod_width', just change it to 'A'.

Thank you, I don't know why I was "afraid" on using A... maybe is because what could happen if I have a dropdwon list of sizes?

Another question related, the same logic applies to ZZYZX?

Sure.

Use 'A' for the overall width.

'B' for the overall depth.

And 'ZZYZX' for the overall height.

They can all have a VALUE list if you want to choose pre-set sizes.

Value lists also work with Hotspots which will allow you to change between presets without even entering any dialogue.
