I am trying to code my autonomous in Vex Coding Studio and when I try to compile the code I get a complication message " no member named ‘rotationUnits’ in namespace ‘vex’ "

Any helpful hints?

Obligatory mention of “VCS is no longer supported, you should strongly consider moving to VEXcode Pro”.

It’s very difficult to debug code without being able to see it. Please post your complete program, remembering to wrap it in [code] … [/code] tags for formatting.

VCS will work, but it is inferior to vexcode pro because it is not up to date and it will never be updated.

In vexcode pro, open a competition template (via file > open example program > competition template) and ctrl+c lines in vcs and ctrl+v them in the appropriate areas and there should be minimal errors (it should be obvious where to copy and paste)

It’s not that big of a deal to switch from VCS to VexCode, and if you are wondering if you should switch or not, Vex is no longer updating VCS so you wont get new features like being
able to use the inertial sensor (correct me if I’m wrong on that).

Really. I just started coding in March

I started coding a few weeks ago. I didn’t know how to code at all until about 1 month ago. I know it’s not that hard to switch because our main programmer last year had to.

If you start from a competition template and follow tutorials it’s pretty simple.

I know this isn’t what you want to hear, but you really really really should switch to vexcode. vcs has been discontinued for over a year now (I think), and continuing to use it will cause you pain. vcs does not have any support for any of the newer devices, like the inertial sensor and the new unreleased sensors. (I’m pretty sure)
also vcs was just bad and buggy and not fun. use vexcode pro, I’m sure you can find some space on your computer for it. and you can pretty much just copy-paste your vcs program into a vexcode one with little trouble (some things might have changed in the last year, idk)

much better to make the switch first. you’ll have a much better time finishing your program.

If you’ve added:

using namespace vex;

You should be able to do

rotationUnits rotation = rotationUnits::rev;

Because the compiler is able to recognize the usage. But, I’m unsure if this would work in VCS or not due to its lack of transparency.
