E2 Preprocessor?

[Colonel Thirty Two]

I noticed that #ifdef and #else were highlighted in the syntax highlighter in E2. I messed around with it, but there is no #define statement, nor does "#ifdef shootTo" work. How exactly does it work?

Edit: maybe this should go in the Expression Help section

Here one example for this:

@outputs Player:entity

#ifdef findPlayerBySteamID()
    Player = findPlayerBySteamID("STEAMID")
#else
    #use this if the "findPlayerBySteamID" function does not exist
    N = findByClass("player")
    
    for(I=1, N){
        if(findResult(I):steamID() == "STEAMID"){
            Player = findResult(I)
            break
        }
    }

you forgot your #endif

I have been using these for a little while and I think it's a neat idea, especially for when i'm using chips that mix non-offical and official code.

#ifdef propSpawn()
propSpawn(S,V,1/0)
#else
concmd("gm_spawn "+S)
#endif

I noticed a few odd things too.
#toggle would become Toggle.

#Button becomes Button, #Slider becomes Slider
#admin becomes Admin.

That #ifdef thing should be documented. I might go back and rework some of my stuff that uses external functions to give them alternatives.

#gc4 becomes GCombat C4
hmm...

Anyway, thanks.
One other question: Does it preprocess when you upload the chip or after every execution? (Basically, when you rightclick on the chip, can you see the #ifdef code?)

[Unsmart]

#ifdef entity:shootTo(vector,number,number,number)
print("YOUR SERVER OWNZ")
#else
print("YOUR SERVER SUCKS")
#endif

[Rybec]

#gc4 becomes GCombat C4
hmm...

Perhaps it's class names.

Wait so #ifdef is a hidden function to see if a certain function exists?

1.its NOT a function
2.its NOT hidden
3.NOT exactly, it tells the E2 if the function exists, not YOU. read my example to see what I mean.
