Okay, thanks. Wow, I have to laugh, @dddaaannn. :D
Here I was trying to work it into a formula and all I was doing was remming out my results. I couldn't see this of course as I was experimenting in immediate mode.
I know ATM there is % ^ * - + / \ << >>
Are there any other mathematical or logical symbols besides those listed - possibly added in this recent update of Pico-8 ?
The manual is thorough about operators: https://www.lexaloffle.com/dl/docs/pico-8_manual.html
Bitwise operators: & | ^^ ~ << >> >>> <<> >><
Logical operators include the comparisons, notably both != and ~= as "not equal" in PICO-8. String concatenation is an operator (..). There's also assignment (=) and all of the modify-and-assign variants (+=, ..=, etc.). #t is considered a unary operator for sequence length. PICO-8 has unary "peek" operators: @ADDR, %ADDR, $ADDR (byte, 2-byte, 4-byte, respectively).
Oh man, lookit all that candy ! Phew ! I will definitely add what you wrote to my reading list.
I do have one more question though, @dddaaannn.
Why have @ADDR() the same as PEEK(), which I use quite often, and why is it faster ? That is not explained in the help file you listed.
It's faster because zep made it faster, maybe for a general intuition that operators should be faster than function calls. It's also one fewer token and six fewer characters. I can see these being useful in tweet carts and fancy memory-based expressions, but someone with more experience than I using them would know better.
fillp(0b0011001111001100) -- four tokens patt = %0x5f31 -- five tokens patt = peek2(0x5f31)
Now that's something I can really look forward to, @dddaaannn. Improved coding ability for tweets. Most of them really rock and are awesome to play if not watch others do so.
I'm in no possession to speed-up my code nor cut down on the tokens. I'll try to continue to use conventional and familiar coding if I can when it's available for my own carts.
It's just interesting to see how far Pico-8 has come ... and what it will become ...
