Thanks. Not a flame war here but:
- In my opinion,
.rasearch would ideally result in finding a code example where .ra is actually used - Searching for
raresults in 132 non-relevant results - Same goes for
aa - And neither are described outright. Absolute angle happens to incidentally be named and defined in a related paragraph (that bitflung cited); rotation (?) angle is never named but is somewhat defined (obscurely, with a muddiness about the frame concept.)
User-friendly documentation is one place where "technically correct" isn't the best kind of correct. PulpScript is supposed to be for n00bs as well as experts, I don't think it would be inelegant to offer a bit more guidance.
If you feel like being that helping hand, I've created a crank related post for general learning around aa ra and applications for crank.
Dump any thoughts there and I can edit together into a guide. Next up is ra and it's going to be a steeper learning curve than aa by far. If you've used it and have anything to share, please do.
