right so, using java, is-there-a/what-is-the-easiest way to draw irregular shapes and then fill them with color?

entirely 2-dimensional, irregular, non-symmetric shapes.

any advice is welcome, thanks in advance!

[Angle]

That depends on which library you're using. I suggest you either look for polygon functionality, or you just use a prepared image.

[Urist McScoopbeard]

polygon functionality it is, prepared images are exactly what i'm attempting to avoid.

Thanks very much man!

While the syntax is quite similar, the horrors of compiler errors and templates and types is quite a thing.

Compare
std::mao<std::string, int> dictionary;
and, for Perl (I don't knke the syntax for dictionaries in Python off the top of my head)
$dictionary {"one"->1};

Also, to beginners most compiler errors look like CERROR 39482 SOMETHING BROKE AND YOU CAN'T FIX IT. C++ errors are among the less helpful ones, though it does improve for modern compilers.

Just want to point out how we're discussing "What's it like to use Python" and you pull up C++ and Perl.  This appears to be fantastically irrelevant.

You were the one that said "you can easily find C++ tutorials" when I asked for Python tutorials, tough

E: I found the tutorial that I lost, tough, with some more creative google searches.

Just found this: http://www.raywenderlich.com/24252/beginning-game-programming-for-teens-with-python
Written by someone BORN AFTER THE YEAR 2000. Now I feel old and accomplishmentless.

super noob question time! In c++, how do I use the '\' character in a string without it disappearing or doing something else?

So I'm writing something for FG&RP using Python 2.7 and I've hit a problem. The following code works as planned:

Code: [Select]

    for item in activeFighters:
        if FighterSelected >= len(activeFighters):
            FighterSelected = 0
        else: FighterSelected += 1
    #   Determine target (create threat evaluation system)
        potentialTarget = len(activeFighters)-1
        while activeFighters[FighterSelected].team == activeFighters[potentialTarget].team:
            potentialTarget -= 1but if I stick this in a while loop like this:

Code: [Select]

    while len(activeFighters) != 1:
    #   Change fighter being controlled
        for item in activeFighters:
            if FighterSelected >= len(activeFighters):
                FighterSelected = 0
            else: FighterSelected += 1
        #   Determine target (create threat evaluation system)
            potentialTarget = len(activeFighters)-1
            while activeFighters[FighterSelected].team == activeFighters[potentialTarget].team:
                potentialTarget -= 1I get an error:

Code: [Select]

Traceback (most recent call last):
  File "G:\WIP\Gladiator Script\main.py", line 410, in <module>
    main()
  File "G:\WIP\Gladiator Script\main.py", line 403, in main
    while activeFighters[FighterSelected].team == activeFighters[potentialTarget].team:
IndexError: list index out of rangeWhich makes no sense as the list indexes were fine prior to the loop and the loop doesn't finish, I tested for that. I would really appreciate some help.

[Anvilfolk]

I'd suggest debugging it through eclipse, or printing all of the indices at relevant points so that you can figure out what's happening. There's really only two possibilities: either you're using a negative index (like -1) or you're going over the size of the array.

[Levi]

Try adding:

FighterSelected = 0

on the second line between the while and for loop.  The only thing I can think of is FighterSelected is somehow getting set to a value below 0 after your for-loop somewhere, which would cause that error on that line.

[Mephisto]

Code: [Select]

    while len(activeFighters) != 1:
    #   Change fighter being controlled
        for item in activeFighters:
            if FighterSelected >= len(activeFighters):
                FighterSelected = 0
            else: FighterSelected += 1
        #   Determine target (create threat evaluation system)
            potentialTarget = len(activeFighters)-1
            while activeFighters[FighterSelected].team == activeFighters[potentialTarget].team:
                potentialTarget -= 1

Are all fighters on the same team? If that's the case, potentialTarget could go negative.

[NobodyPro]

Problem solved. 'if FighterSelected >= len(activeFighters)' was checking for two, and I'd forgotten to stick a -1 on the end of that to account for the fact that lists start at position 0.

EDIT: I went and fiddled with the formatting in the txt files I was pulling data from and my other problem fixed itself. The problem I had had NOTHING to do with those txt files.

[HopFlash]

How would you suggest I handle pathfinding?  In particular, the code is Python and simple pathfinding is good enough.  Ideally I'd like something similar to DF, with priorities of 'don't pass through here if you can avoid it' and whatnot.

In a bit more specifics, the idea is to have, more or less, 'DF on a spaceship' and deal with issues like spacing and whatnot, so ideally it'd run a test 'pathfind to this location safely' and then 'pathfind here and use a space suit'.

EDIT:

This is the best thing.

perhaps an interesting visualisation for pathfinding:

"Jump Point" seems as an interesting alternative but I for myself havn't tried it.

What's the difference between Python 2.7 and 3.3?
