DOCUMENT: Miscellaneous source findings and thoughts

[Solver]

It seems to me that this information has been pretty scattered thus far, so time to put it together.

It has been discovered that there's an easter egg in the game which acts if you enter "pacman" in the Chat window. - The Big Mc

The game has a boolean g_e3Demo variable that is set to false. If true, then some parts of the interface are skipped, so that the game starts/quits without main menu, which is more of a demo mode indeed. - Dale and Solver

The sprite limit of 200 is defined as a global constant. - Immortal Wombat.

The AI won't move around its own 12-stacks because the pathfinder considers those squares to be passable, and the units keep trying to enter the square occupied by 12-stack, and fail. - Dale.

From the CtP1 space layer, the wormhole code is still in. That includes stuff for moving the wormhole each turn, for instance. - Solver

This was known previously, but it has no effect as far as anyone can make out.

As seen from the code, it creates a unit. Might be just that it doesn't get on the map .

[The Big Mc]

if(!Flag(k_UDF_PACMAN)) {
m_movement_points -= cost;
m_movement_points = max(m_movement_points, 0.0f);
ClearFlag(k_UDF_FIRST_MOVE);
}

Probably needs a specific sprite a well? One that's missing like the War Walker beta.

[Solver]

If I get it correctly, it creates a unit of type which is the second-from-end in the unit database.

Actually, the function returns: ASTAR_BLOCKED so it's viewing it as unpassable, but then the Astar function doesn't look for another path when returned ASTAR_BLOCKED it just closes that node.

What we need to do it specific a different return like: ASTAR_OCCUPIED and when that's returned to the Astar function, make it keep the node open but try other directions from there.

You forgot the GetNearestWater function, Solver.

Solver, you have a PM
Sorry!

@Everyone, good luck with the project!

Just stepping back for a second. All this time waiting for the source code -- and we use it just so we can play Pacman!!!

And here is a thread that describes the fix of the GLHidden flag for goods does not work bug.

I also found something else that could be interesting in the Rankingtab.cpp there is a function called GetTurnStrength, I tracked it down to the Strength.cpp and found these possible arguments for this function:

STRENGTH_CAT_KNOWLEDGE:
STRENGTH_CAT_MILITARY:
STRENGTH_CAT_POLLUTION:
STRENGTH_CAT_TRADE:
STRENGTH_CAT_GOLD:
STRENGTH_CAT_POPULATION:
STRENGTH_CAT_CITIES:
STRENGTH_CAT_GEOGRAPHICAL:
STRENGTH_CAT_SPACE:
STRENGTH_CAT_UNDERSEA:
STRENGTH_CAT_UNITS:
STRENGTH_CAT_BUILDINGS:
STRENGTH_CAT_WONDERS:
STRENGTH_CAT_PRODUCTION:

So what do want to see on the powergraph in addition.

I would like to see a pollution graph, maybe also an additional wonder graph, maybe also a geographical graph, maybe they could be displayed only if you have an embassy with the corresponding player.

if i remeber right isen that the war walker

while(y < 0) {
y += g_mp_size.y;
x = (x + g_mp_size.x - (((g_mp_size.y / 2) % g_mp_size.x) - 1)) % g_mp_size.x;
}

I found this at the end of Mappoint.cpp in
function Norm2Iso -----> void MapPoint::Norm2Iso(const MapPointData &pos)

interesting coding.. probably to do with the isolinear diagonal map tile drawing. Looks pretty mad, it assumes y is 0 I think, otherwise it seems to be wasting time increasing y until it reaches 0 in g mp increments.

Just something that caught my eye.. this coder on that file seems to use whiles like If statements, whereas I rarely do.

AAHHHHHHHHH THE HORROR!!!!!!!!!!!!!!!!!

It's for doing vertical wrap around. The math is very, very tricky for any map whose vertical size is not a multiple of it's horizontal size.

If you don't have vertical wrap turned on, you should ever hit that loop. It's only a loop, I think, in case something wraps a really long way. Normally it would only go through that once.

Mr Ogre,
Completely off-topic, but I sent you a PM.
