Pakz	Ok, that same line seems to work. But I wanted to do it like below. if x2>-1 and y2>-1 and x2<32 and y2<32 then Rotated(x,y)=Tiles(x2,y2) end if --v edit: You do not appear to have a Continue command either? I use these quite a lot for jumping to the next cycle in a loop. for j = 0 to 10 for i = 0 to 10 if i==j then continue ; jump to the next Next. ..code.. next next --v Above, if I got it right. You do not check the same entities in the loop.

Jayenkai	Your first issue might be end if vs endif.. I'll add that into the parser checks. I've written it as specifically endif because I'm aiming for SingleWordCommands.. But, yeah, people do write "end if", so I'll have to add a check for those. Second issue.. Continue/Break are commands I tend not to use nowadays. One of those things where it didn't do what I expected it to do in a different language, because different languages do things in different ways. IIRC, the language I fell out with it in, when I used it, it stopped the loop dead in it's tracks and exited it. Which is what I would expect Break to do. I found that very frustrating, so opted to do other methods instead. But, yeah, it should be in. Continue = Goto Next, continue the loop Break = Goto the line after Next, abandoning the current Loop Is that right?! Does that "feel" like the right method to everyone? -=-=- ''Load, Next List!''

Pakz	Break seems like something I would use also
Thu, 22 Jul 2021, 12:08
Dan	Hmm other languages use exit or exit loop instead of break. AutoIt, for e.g. has an optional level parameter, and with it you can exit multiple for-nexts at once. https://www.autoitscript.com/autoit3/docs/keywords/ExitLoop.htm

Jayenkai	Eek, a parameter could be tricky.. .. maybe ... I'll test it and see. I've got the basic version "mostly" working, but it can be glitchy in the wrong places. It's fairly easy to trip it up, right now. .. but, hey, what else is new!! I'll post the results later/in the morning, depending on how twisted in knots it all gets! "Exit" will be added as an alternative. -=-=- ''Load, Next List!''

Jayenkai	Ok, I think I've fixed Pakz' "if then ;" issue. It should know what's going on, now. I've also (I think) got "end if" compacting down to endif. I don't think either of those should cause any issues, but as always, let me know if I've knackered something.

Jayenkai	v3geg (As always, might need a refresh to catch up) The obligatory set of speedups, which have been gradually implemented over the past couple of days. This version broke quite a lot of functionality, earlier, as minus numbers because infinitely more chaotic than they already were! But a little to-and-fro'ing and everything got back to where it oughta be. .. I hope! As always, be sure to stress test it with anything you can think of. I don't think anything has changed other than speedups. If you'd like to check the Optimisationalism 2 test, you should (hopefully) find your numbers have improved a fair bit.

Pakz	That is impressive! How do you rotate that text into 3d? Is it a kind of fake 3d?
Thu, 29 Jul 2021, 09:21
Jayenkai	No, just the simple SetSize command with a Cos attached, so their width is reduced when near the edge, and backwards, too. If I used FontSize, that wouldn't do the trick. Size works because it can scale x and y independently and also invert the x. -=-=- ''Load, Next List!''

Pakz	I was experimenting a bit with jse. I noticed there is no way to erase pixels in the editor once you placed them?(for the transparent ones) Is there a erase shortcut that I am not aware of?
Thu, 29 Jul 2021, 13:32
Jayenkai	Aah, good call. Sorry, that's another one of those "I've been doing it so long, it's second nature to me" things. Magenta (255,0,255) is traditionally (for me, at least!) transparent. In the colour picker, there's a lonely Magenta on its own at the bottom. This is your transparent colour. I need to make that more obvious. -=-=- ''Load, Next List!''

Jayenkai	Been playing with Dan's Amiga code again, and managed to squeeze a bit more out of it. Removed all references to Float() since those are already assumed by JSE. (Note : You'll have to Int/Round/Ceil/Floor if you want crisp numbers, here) Float was slowing it down, especially with so many instances. I also reduced the number of loops it does, but replaced the pixels with lines so it's not so obvious.
