Hey guys. I've got the latest twcore distro, and I'm having a serious issue that I can't figure out....

I'm rather new to Java, so bear with me on my obvious newbishness.

Here's the problem... I can have a bot log in, accept and respond to PM's and whatever else I want it to do... but... It's losing the death messages. Sometimes the kill tracking works, most of the time it doesn't. Seems to be completely random...

I've put tracers in the code where I can, and it seems like the death messages just disappear. I've got reliable kills turned on, but to no avail.

I'm using j2sdk1.4.2_07. What am I missing? Why isn't this working? It doesn't seem to lose PM's or any other type of message... just the kill messages. It's very frustrating.

I just tried j2sdk1.4.2_08 with no success either.

Check the settings for Routing:DeathDistance. This the maximum distance away from the location of a death that a packet will even get queued. Even with this set very large, I still get missing death packets with PowerBot.

Dude. You rule.

I set it to 16384 and now receive the kill messages in the bot every time!

Ew, thats a bit of overkill IMO. Instead, what I would do is turn on reliable kills so that the bot is the only one that gets all the death packets. Most players don't need all of them when they're 16000 pixels away. This can be achieved using a call to

Code: Show/Hide

m_botAction.setReliableKills(1);

What this does is send a chat message containing "*relkills 1" which according to shanky.com, "If sent # of 1, you will always get reliable kills."

Doesn't work. All that does is makes the kills the server DOES send reliable. It still only sends based on the arena setting. Also, even with reliable kills AND a maxed setting, they can still be dropped.

As I said in the original post... reliable kills IS enabled. But still doesn't receive them if outside the range specified...

ekted owns you all, good luck with the bot wired

(off topic) just wondering ekted, what zone do you play?

Powerball

Play???

Thats a bit of an understatement.

Hmmm... learn something new every day

Yes, sending every death packet to every player is a bit of an overkill, but remember death packets are rather small, so it doesn't matter that much.

More issues....

Ok, I'm trying to create a method to announce the current location of a player... I've gotten the bot to spec on the player....

But how the hell do I get his current location?

I've tried PlayerPosition.getXLocation() and PlayerPosition.getYLocation()... I've also tried Player.getXLocation() and Player.getYLocation()...

I get X as being very high, looks like pixels... but Y always comes back as 0. I can't seem to just use %coord in any way or fashion....

So how the hell do I do this?!

Ok. Got it. A very itty bitty typo is what hung me up... Heh. Gotta love the little things... Here's the code I came up with, I'm sure there's a more efficient way, but I'm still a newb, so ... forgive me.

Code: Show/Hide

public String getCoords(Player p) {
   int x=0;
   int y=0;

   x = (((p.getXLocation()/16) * 20) / 1024) ;
   y = (((p.getYLocation()/16) * 20) / 1024) + 1;

   String xc[]={"A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"};

   return xc[x]+y;
}

Ok, I'm assuming by those two comments I either did this the REALLY HARD way... or I did something ingenious... I'm opting for the first of the two possibilities...

What's the better way of doing this?

wiredfreak · Posted: Sat Apr 16, 2005 12:28 am Post subject:

Alright. Since I was LAUGHED at for my first try, here's a refined attempt!

Code: Show/Hide

public String getCoords(Player p) {
String c[]={"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T"};
int x=p.getXLocation()/819;
int y=p.getYLocation()/819)+1;
return xc[x]+y;
}

Better? I've only been doing this for a whole four days... Ya can cut the newbie some slack! Last time I coded was back in Dos 6.22 in Borland C 3.1!

Sam,

Thank you for the help. I've changed the mathematic lines... but, since this is Java, I don't know how to make the other portion of your code work...

I attempted to use it as-is to no avail, I get errors. I tried modifying to what I thought might work... still didn't work... so, I'm still stuck using the humongous string array. heh.

Any other ideas?

Haha, this

Code: Show/Hide

String xc[]={"A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"};

reminds me of my "31337" code to convert "1337 5p34k" to normal language:

Be careful trying to simplify integer math.

Code: Show/Hide

a = b / 4 * 5;

is not the same as

Code: Show/Hide

a = b * 5 / 4;

Also, most compilers are very good at detecting simplifications in arithmetic--even ones that humans would not see. In this case, it's best to write code that makes sense and is readable, and let the optimizier do its job.

I am 100% against the String class no matter how simply it is used. Consider this code:

Code: Show/Hide

String function ()
{
String a;

// blah blah

return a + "wins the game!";
}

Whenever "a" is assigned a non-null value, memory is allocated. The return value is a string that needs to be created (allocated)--twice! And when the return value is assign back in the calling function, another allocation takes place. This is retarded. Maybe the use of this function is limited, but once you get used to using Strings, you will use them everywhere, and the above code could easily be 50x faster. No commercial app that handles large amounts of text (Notepad, Wordpad, Word, Excel, VisualStudio, IE, Netscape, Firefox, OpenOffice Write, etc) would be caught dead using String.

Well, until I'm shown a better way to do things, it's going to be difficult for me to improve my coding abilities... Simply laughing at me or criticizing me without offering solutions to the problems doesn't do much other than show immaturaty and perhaps insecurity. But I'm not going to sling hash here... I came here for help, and the only ones that have really offered it are Mr. Ekted and Sam, granted that the former is the biggest offender of being offensive right now.

I'm new to this. I've said it more than once, and it should be quite obvious. It's similar to what I used to do many years ago, but I've forgotten quite a bit and am relearning everything... and then some. So, any future problems I have, I'll refrain from posting my spaghetti and simply ask for someone elses solution and see how close I came to being efficient with my own solution (if mine even works).

Regardless of how inefficient my code may be, it still functions the way it was designed and gives the desired results. That in itself should speak volumes when considering that when I posted that code, I'd only been working with Java and twcore for a whopping 4 days, without ever having looked at it before. Not to mention I haven't coded since the DOS 6.22 days in anything other than Tribes/1 gamecode (which was a disaster anyway).

And as to my simplification of the math I used, it actually simplified down to 819.2, but to keep it simple, I dropped the .2. It still gave me reliable coordinates, so it wasn't something I was too concerned with. I've decided to use Sam's solution to that problem, as it's just as effective, and I like how it looks. And he showed it to me without being snyde...

Cheers.

Sam was the only one who actually gave you a solution.

Anyway, I think you should look in the MERVBot source on how to do such things.

I think this is catid's C++ version on what you're trying to do (MERVBot v38, map.h (line 14 - 15) and map.cpp (line 32 - 54)):

Code: Show/Hide

// Code from map.h, line 14 - 15:

#define TILE_MAX_X 0x400
#define TILE_MAX_Y 0x400

//Code from map.cpp, line 32 - 54:

Sint32 getNumeric(Sint32 y)
{
return (y * 20 / TILE_MAX_Y) + 1;
}

char getAlpha(Sint32 x)
{
return char('A' + x * 20 / TILE_MAX_X);
}

String getCoords(Sint32 x, Sint32 y)
{
String s;

char alpha[2];
alpha[0] = getAlpha(x);
alpha[1] = '\0';

s += alpha;
s += getNumeric(y);

return s;
}

This, would burn Ek's eyes again, though.

We were taught (and forced at tests) to use the String class in Java, and well, I'm sure the code I always have to use in my applets sucks.
Although, I'm the only one who actually knows how to get my applets to work, not even the teacher could teach me how to write better code.
Ah well, I don't like Java anyway.
