Random - negative numbers?

Uncategorized

Hi

I’m trying to create a script that random rotates a selection of families. It works ok now - but I can’t figure out how to use negative values.

An example - I would like the families to be random rotated minimum -10 degrees and maximum +10 degrees (theese numbers should be input), but I can’t figure out how to get negative numbers from Math.random.

I’m not a programmer so it’s a lot of trail and error :slight_smile:

Does anyone know how I can achive this?

Thanks
Jorgensen

Generate random numbers between the domain 0-20 and minus 10 :wink:

Hi Thomas

Thanks for the fast reply.
The user should be able to enter different numbers, so the -10 and +10 varies.

So the numbers could be -3 and +10 - is there a way to handle that?

Thanks

input the domain 0-13 and minus 3 from the result.

This would be my solution, fairly simple but it should do the trick!

If you are trying to rotate families maybe you could add + 360 somewhere

Thanks Daan

I think I need some more time to look at it - I also need to figure out how to use the families current rotation as reference.

take a look at this for that:

Clockwork has a couple nodes for normalizing values including one that will scale based on a given range, which is essentially what everyone is suggesting.

Hi Nick

Sorry for this noob question - but what is Clockwork?

Clockwork is one of the more popular custom packages (containing many useful custom nodes). You can download it through the package manager in Dynamo.

Yes, you could see Clockwork as downloadable content with a lot of extra nodes to use in your Dynamo Environment!

You could consider using the OOTB node Math.RemapRange
