Wait, it treats line breaks as semicolons? If it wasn't for certain lines of code not using a semi-colon at the end (eg IF instructions), then you could have made your program add line breaks at the end of semicolons.


Also, for your hockey game, something I thought that would be cool is if you tried making an actual hockey game but with 2 players on each side, one controled by the AI unless you switch to it. You could also make the field of play 3D mode-7-like like in Mac Bernicks's Trailblazer game.

That could work.

But to clarify the semicolon thing (I think but do not know) but the only time you don't need a semicolon is before the final END; statement in the loop, if branch, function, ect.

Wait, do you mean the last command before an END doesn't need a semi-colon? That would be a bit inconsistent.

Yeah I am focusing on MinePrime now (I have to look into the AI system learning and stuff, also I am dreading the program editor ) Does anybody know a way of detecting a new line in a string?

Code Select Expand


A:=1; //this is fine just look for the semicolon
If A==1 then //look for then
A:=2 //this doesn't need a semicolon to compile corectly so I can't detect when to make a new line :(
end; //this line and the previous line will get smooshed together because of the lack of the semi colon

The general ascii code for the newline character is byte 10 ('\n'). I don't know if the prime honours the ascii standard though

Doesn't the prime use Unicode?

[Unicorn]

Unicode - also known as unicorn-code

[Snektron]

Doesn't the prime use Unicode?

I think the first 256 characters of unicode are the same as the ascii characters.

I think the first 256 characters of unicode are the same as the ascii characters.

Yes, or more technically: The first 256 characters of Unicode are the same as the 256 characters in ISO-8859-1, and the first 128 characters of ISO-8859-1 are the same as the 128 characters in ASCII.

[Dream of Omnimaga]

Ah, right. Thanks for the info. Are those first characters as large as the rest of the unicode characters when in unicode mode?

Yup, but I only exclude it on mock up test programs

[Dream of Omnimaga]

I would recommend including it in public program releases anyway, in case future OS updates patch this.

[alexgt]

That is what I do but I don't think it is a bug that necessarily needs patching

the ; is probably only there as a marker that the expressoin has ended. Since an 'END' token is not allowed in a mathematical expression, the compiler knows the expression has ended anyway.

[alexgt]

^ That is probably how it works

Indeed. I'm just suggesting as a precaution, in case HP does it anyway, because it would suck if your games stopped working completely just because of a missing semicolon at the very end of the code. Thanks Cumred for explaining by the way

I could make it part of the SIFS program editor that when you exit it inserts semi colons where it is needed .
