Posted: Mon Mar 12, 2007 9:19 pm Post subject: Increasing a integer in delphi |
|
|
As first post in this section here's a piece of code that will increase the value of i with 1
Code: |
var i: integer;
var pi: ^integer;
begin
//..... (some code that sets i to something)
//now increase with 1
pi:=@i;
pi^:=pi^-2;
i:=i+1;
inc(i,2);
end;
|
there, now was that so hard ?

Wow, I've always thought I should just do
But now we include pointers. Lol.

is for lame people.
is 'teh pwnage'
or (will it allow this?)
You might have to move i into eax then eax back into i... freaky thing that inline asm is.

I tried inc(i) before. For some reason Renko claims it doesn't work. I started using i:=i+1 ever since.

I am shaking my fists at you like a jewish mother in denial. Yeah, types can get annoying.

yea... is it just me, or do people always make things harder than it really is. Or is DarkBytes code better in some way?

lol, but I meant in general as well, I see a lot of code that doesn't really need to be there.

I could look through public ASM scripts and truncate almost all of them (or make those jump changes more efficient via nop/jmp instead of a conditional). However, I think we can expect DarkByte to only make something more complicated than it is on purpose (like for this instance, to be 'joking' around. Oh DarkByte, you jokester you.)
Renko: Was your type an integer? xD (signed/unsigned shouldn't matter)
inc(i) should be the equivelant of i++ (in c++) or i:=i+1 (in Delphi).
Or you can do the ol' inc(i,5) for an i:=i+5, etc. If you can do one, you should be able to do the other. I think the overloaded versions exist because one in asm will be inc [mem] (or reg), where the other would be add [mem],param (or reg)
In other words... if one works, as should the other.
