Scaling both values over time
Hi people
I am tentatively getting into expressions and though I think they are extremely powerful, I do find them frustrating when I can’t work out what is going wrong… could anyone help?
I have written this expression on the scale property;
value+(time*3)
… basically I want both vertical and horizontal values to increase equally over time, but it seems all this expression does is increase the horizontal over time. I have tried a few things but I can’t seem to come up with the all important line. What am I doing wrong?
Thanks in advance.

You need to add it to both dimensions, like this:
delta = time*3;
value + [delta,delta]Dan

what does delta mean? Is it just a random term or does it mean something?
Many thanks for your help, it works exactly how I wanted.

It’s just a variable name. I usually use “delta” to represent a difference or an incremental value. You could use pretty much anything though.
