#define

[Troodon]

Ok, thanks.

I don't want to sound idiot, but is the #define making a normal variable?

[makslane]

The #define just create a 'replace' in the code.
If need to use some value, like 3.1416 in your code, you can make a define, like this:

#define PI 3.1416

And just use PI in the code.
Please, refer to some C docs.

[Troodon]

Wow, thanks!
I haven't read any C docs, only the GE documentation. Maybe I should start learning C...

Yes, define is more than storage for values of strings. You can use it to store portions of code. That code will go uncompiled at first..

#define HEAL Hp+amount, MaxHP

then later in code...

amount = rand(10);
hp = min(HEAL);

you can see that it can act somewhat like a function, without the overhead of the function. It stores the formula and nothing more. You dont have to remember what arguments to pass it. You could also wrap the min() around the contents of HEAL.

Note that convention says use capital letters for define labels, and that the line is not normally appended with ; but it is legal.

one interesting use is to shorten key words...

#define GaAiC getAllActorsInCollision
#define EA "Event Actor"
later in code...

GaAiC(EA,&num);

thats kinda silly, but shows how you can compress your code. If you use certain long key words repeatedly, you can actually shorten up your code considerably.

From my experiments, it extends to the compiled program too. however, you might find that it slows things down a bit. Makslane will know better than I.

I still like it!

[Troodon]

Ok, thanks!
Is there any place (in web) where I could find that kind of C script things?

For example what's the '|' doing?

[Sgt. Sparky]

that is a setance end

[Troodon]

Sentence end?

[Sgt. Sparky]

yup.
that way it does not get glitchy

[UltimatHedgehog]

how do you type '|' it's not on the keyboard

[Kodo]

look at the bottom left of your keyboard, hold down the left shift and press the key next to it (backslash). Least that's what it is on a UK keyboard.

[UltimatHedgehog]

thats capital Z there is one that is 2 lines one on top one on bottom looks just like | but with a space in the middle but thats the right one

its only a | in certain fonts though

[Kodo]

thats capital Z

That'll be why I said "on a UK keyboard", keyboard layouts vary slightly from country to country, on mine the | key is next to the Left Shift

[Game A Gogo]

in Canada keyboard (Should be similar to U.S.A.) English, its Shift and Back slash (Right above the Enter), and for French, its should be Alt Gr and 6

[UltimatHedgehog]

what you said about the canadian is on mine so yes youre right its like usa keyboard
