Limit editable hotspot movement to arbitrary values

jc4d — Wed, 13 Apr 2022 06:21:10 GMT

Hello,

I would like to have a editable hotspot to move only by given values but obviously I get a numeric error when I check the script.

Is there a way to "limit" the hotspot's movement to the given values only?
Practical example 🙂

On the parameters tab I have this:

VALUES "Height", '1420', '1580', '1880', '2120', '2280', '2990'

On Master:

unID = 1

On the 3D script

HOTSPOT 0,0,0, unID, Height, 1+128 unID = unID+1 HOTSPOT Height,0,0, unID, Height, 2 unID = unID+1 HOTSPOT -1,0,0, unID, Height, 3+128 unID = unID+1

Juan.

The hotspot movement is a length, so your 'Height' parameter needs to be a 'length' type and not 'text' type.

The value list will be lengths in meters with not quotes ...

VALUES "Height", 1.420, 1.580, 1.880, 2.120, 2.280, 2.990

I hope is ok to ask another question here since it is somewhat related. If not the mods are free to move it to a new topic.
Is it possible to give a max and min lenght limits to the hotspot and define the movement steps?

You could use Range and Step to do something along the lines of

VALUES "Height" range [1, 3] Step 1, 0.2

Probably bad syntax on my part. I have not used the values command with range and step before. Updated previous post with what I think is the correction. Had an extra comma.
