Here's an interesting project I ran across on sourceforge - bundled eclipse 
distributions:

http://www.easyeclipse.org

A

The bitmask is just a convienient way of representing all the boolean values 
for if a player can see a system. It can be coded both in PHP and directly in 
MySQL queries. The visibleTo field is an integer and only means something 
when expressed in its binary form. So, if only player three should be able to 
see a system, you'd need the bitmask

00100000

For players two, five and seven to see a system, you'd have bitmask

01001010

To avoid dealing with the decimal integers (which is unwieldy and defeats the 
point of having them) the bitwise operators |, ^ and & need to be used. Now, 
I'll probably make a hash of explaining this, so refer to PHP or mySQL docs 
for a better explanation of how these operators work:

The | operator - bitwise OR:
The result is the equivalent of an OR operation between each bit.

0010010 | 0110001 = 0110011

This would probably be what you would use to register that a system had been 
explored by someone - you would just OR the visibleTo field with the integer 
2 to the power of the player's id. This can be done directly with a  MySQL 
query.

The & operator - bitwise AND
The ^ operator - bitwise XOR

The beauty is that several masks can be easily OR'd or AND'ed or XOR'ed 
together, for example when determining which systems can be seen due to map 
sharing treaties.

Catherine: Are you using Firefox 1.5 with all the default options?

I just tested it under Windows XP - it works very well here and there is 
no selection-when-you're-dragging at all.

I can't actually get this to work at all. It comes up in Firefox, but 
clicking the "make window" button doesn't do anything. Think my 
computer may not like Java- any suggestions?

Really? There definately was with me was night... how intruiging. FF1.5 I 
assume? It may be that your ultra-fast desktop responds so quickly as to 
prevent the mouse from moving overly far away from the drag item. I fear that 
windows users will probably still get the drag.

No problem here - works perfectly.  I can drag it as quickly as humanly 
possible with the selection-bug.

Heres a possible alternative: ADOdb (adodb.sourceforge.net, available through 
portage). Claims it is fast and intuitive. Also supports rather than relies 
on PHP5.

Well, that's a little deflating. For some reason, PEAR DB only supports MySQL 
<=4.1 with PHP5. Why?? Craziness. I'm looking for some other alternatives.

I propose that we move, where possible, to using existing PEAR PHP modules in 
our code as it will save us time and make the code clearer. This will however 
require the installation of appropriate PEAR modules (DB, Auth?) locally for 
testing. Any views on the use of PEAR in the trunk?

Between game turns yes.  What about between combats on the same turn?  
There is a potential unfairness as with ten combats a ship could 
accumulate no damaged components even though one of them was dealt 90% 
damage each combat.

Actually it's easier to code if it isn't a component - that's why I 
remembered your idea.  It's easier because ships, units and colonies are 
DynamicObjects, all of which should be able to receive damage, and so 
the $damage variable lives in DynamicObject.

I agree with what Alastair is saying, partial damage in between turns can  be 
just ignored. However, I do have an idea where if the component have  health 
50% or above after combat then it will be fully repaired on the  next turn but 
if its health is greater than 0% and less than 50% then it  will start with 
50% health next turn. Don't know if this will use less  resources though.

As for ship itself with damage resistance, I would suggest what I  said on 
the wiki to save some additional coding. Basically all ships must  have a 
special component called "Hull structure" (or something like that) and it  should 
absorb some percentage of damage should the weapons  penetrate the 
armour/shields. The percentage of damage it receives  should be small, the idea being 
usually it's the  last thing that gets destroyed as its destruction signifies the 
death of  the ship. However, there should be times when the ship dies but not 
all of  its components are destroyed to simulate catastrophic hull/internal 
structure  damage. Finally its damage resistance should also scale with  the 
size/class/mass of the ship and the damage it receives should be  saved between 
turns.

I'm not sure the old SEIV style isn't OK - I can imagine that damage which 
doesn't deal terminal damage to a component would be light enough for on-ship 
damage control to repair. In actuality, it would be that the destruction of a 
component only represents it being irreparable without a major space-dock 
refit. I'm not sure how easy it would be to code damage even being carried 
forward within a turn with the current structure that seems to be emerging - 
in addition this could be explained by the above argument, that the damage is 
light enough for the component to be repaired by ship crews during the time 
represented by one game turn.

I cannot see a practical alternative that does not involve more coding and 
resources than the benefit gained, but a new funky system would be 
interesting... :) The other question is how would making ships more fragile 
affect the gameplay? Would it be a more or less interesting game to play with 
such a feature?

How is ship-damage going to work?  We could have a very simple 
slightly-SE4ish means:

a) all components in a ship have a damage resistance.  When they are 
dealt this much damage the component is destroyed.  When all components 
are destroyed the ship is destroyed.  If a component with 40MT of damage 
resistance is dealt 20KT of damage in combat, by the next game turn this 
damage is forgotten.

Simply, this means:
1. Only components have damage-resistance
2. Components forget the damage they have received between turns if they 
are not destroyed

Effects:
i. We have the paradoxical situation of a ship existing with zero 
components during a retrofit
ii. Components not remembering their partial damage saves programming, 
saves extra fields in the database and saves on processing

I would prefer if the ship itself had a damage resistance, and once this 
hits zero the ship is destroyed.  This defeats the problem ( a.i above 
).  It also opens up the possibility for an idea of Ruofan's - hull 
damaging weapons.  I'm not sure about a.2 - maybe after each game turn 
it should be forgotten but during a turn (remember a turn can have 
multiple combats) it should be remembered.  That's only fair really.

To all developers at the University of Edinbrugh (and most likely other 
institutions too),

Just realised we have a gem of a resource at our disposal in the form of 
O'Reilly Safari Tech Books online. The University library has access to 
nearly all the O'Reilly tech books (those with white covers and sketches of 
animals on front). If you go to www.lib.ed.ac.uk using the university proxy 
cache service, go to "resources" -> "books, ..." -> "electronic 
Books" -> "Safari Tech Books Online" theres a whole load of useful reference 
books. Easier than trawling the web for that little tidbit. They're also 
fully searchable.

Okay I've documented the code in UML.  It's not particularly helpful for 
this error, but hopefully it helps others read the code.

I've had a small go at a class diagram for the systems/system map model. I 
think this arrangement will make it easier to catch some of the bugs we're 
beginning to see surface. I also did it to investigate how useful Dia is, and 
I've found that it is well worth a look for this sort of thing (very easy to 
use).
