Yeah. I just heard somewhere that for the 4 directional key detection they were much slower than the larger way.

Ya, I think I remember that but I don't think it's that much slower, personally.

Well, it actually made a big difference in games like Illusiat 13, apparently (someone modified it once to check). Like under 2 FPS framerate during walking instead of over 3.

Is it me of is Goto sometimes faster than While/Repeat...? O.O

Make two programs, each having the following code at the very start:
Code: [Select]
1->A
While 1
rand
A+1->A
End
Code: [Select]
1->A
Lbl 1
rand
A+1->A
Goto 1

This Goto speed gain over While/Repeat only happens if the Lbl is at the very start of the program.

A For loop is even faster since I can then remove the A+1->A line, but if it's code with no variable incrementing, then For seems slightly slower than Goto (although faster than While/Repeat).

Could someone else run those tests to confirm? Although the speed gain would be negligible for large code, maybe it could be a slight speed boost in some cases (although the Title/menu code would need to be placed below the gameplay one, with a Goto at the very start of the program.

Another idea is to have a subprogram for the main game.

Due to dissatisfaction, I will be inactive on Omnimaga until further notice. (?? THP hasn't been much success and there's also the CE. I might possibly be here for a while.)
If you want to implore me to come back, or otherwise contact me, I can be found on GitHub (bluebear94), Twitter (@melranosF_), Reddit (/u/Fluffy8x), or e-mail (if you know my address). As a last resort, send me a PM on Cemetech (bluebear94) or join Touhou Prono (don't be fooled by the name). I've also enabled notifications for PMs on Omnimaga, but I don't advise using that since I might be banned.

Convert Hex to Dec
Code: [Select]
DelVar SInput Str1
For(I,1,length(Str1
inString("0123456789ABCDEF",sub(Str1,I,1))-1 -> C
S+C16^(length(Str1))-I -> S
End
S
