Requirements for Buildings/Techs/Units

[MoLAoS]

One thing I have in my version of Glest is a requirement system that is very open.

You can require resources, items, buildings, units, techs, etc for the production of something. It is implemented as vectors of points or pointers + ints.

So I can require an arbitrary number of techs or items. I implement building components as items since Glest derivatives don't have any sort of mesh/model updating like adding a tower to a model. I can set any number of buildings as requirements as well.

Can I manage this in the JS files for Pyrogenesis. I read a thread that has posts a few years old saying you can't use more than one upgrade as a requirement, has that changed?

Greetings @MoLAoS. I ve been told by management to go away but if it helps you ...

Resources defined in /resources.js are used to make buildings and units. But then you need to adjust the UI to show your new resources to the player. This was as of version alpha 23b at least.

@happyconcepts This is resources like wood/stone/metal/food or does it handle techs and buildings?

[happyconcepts]

wood stone metal food are defined in resources.js and apply universally.

The techs are in another folder and also support faction-specific technologies too. So in my mod the Dutch have a mercantile tech upgrade whereas the French get a different one.

Technologies can be defined as a pair so that the player is able to utilize only one or the other but not both.

Buildings are just like units, requiring food metal etc. or whatever else you add to resources.

Here look at the files on github..

@MoLAoS hey how can I get involved with glest? Im not an artist but anything else goes

Glest, Glest Advanced Engine, and Mandate(my fork) are functionally dead. MegaGlest is still somewhat active, though less so than 0AD. You can google megaglest forums or something to find the discussion.

So in the identity.js file there is a line:

"<optional>" +
        "<element name='RequiredTechnology' a:help='Optional name of a technology which must be researched before the entity can be produced.'>" +
            "<text/>" +
        "</element>" +
    "</optional>" +

I'd like to require more than one such tech in some cases. I'd also like to require Units or Buildings, and Items if I get them added. Lib-XML2 plus associated c++ code in Mandate allows me to have something like:

      <unit-requirements>
      	<unit name="some building1"/>
      	<unit name="some building2"/>
      </unit-requirements>
      <upgrade-requirements>
      	<upgrade name="some tech1"/>
      	<upgrade name="some tech2"/>
      	<upgrade name="some tech3"/>
      </upgrade-requirements>
      <item-requirements>
      	<item name="some item1" value="10"/>
      	<item name="some item2" value="5"/>
      	<item name="some item3" value="2"/>
      	<item name="some item4" value="1"/>
      </item-requirements>
      <resource-requirements>
      	<resource name="wealth" amount="2000" plus="0" multiply="0"/>
      	<resource name="population" amount="10" plus="0" multiply="0"/>
      	<resource name="logs" amount="50" plus="0" multiply="0"/>
      	<resource name="stone" amount="50" plus="0" multiply="0"/>
      </resource-requirements>

Is this a valid structure?

"<optional>" +
    "<element name='Requirements' a:help='Optional name of requirements that must be met before the entity can be produced.'>" +
        "<element name="Technologies">" +
            "<attribute name='datatype'>" +
                "<value>tokens</value>" +
            "</attribute>" +
        "</element>" +
        "<element name="Structures">" +
            "<attribute name='datatype'>" +
                "<value>tokens</value>" +
            "</attribute>" +
        "</element>" +
        "<element name="Units">" +
            "<attribute name='datatype'>" +
                "<value>tokens</value>" +
            "</attribute>" +
        "</element>" +
        "<element name="Items">" +
            "<attribute name='datatype'>" +
                "<value>tokens</value>" +
            "</attribute>" +
		"</element>" +
        "<text/>" +
    "</element>" +
"</optional>" +

Then the data in the file would be like:

<requirements>
	<technologies>
		<technology name="some tech1"/>
		<technology name="some tech2"/>
	</technologies>
	<structures>
		<structure name="some struct1"/>
		<structure name="some struct2"/>
	</structures>
	<units>
		<unit name="some struct1"/>
		<unit name="some struct2"/>
	</units>
	<items>
		<item name="some item1" value="10"/>
		<item name="some item2" value="5"/>
		<item name="some item3" value="2"/>
		<item name="some item4" value="1"/>
	</items>
</requirements>

Your method is definitely easier for modders (and the wfg team if they ever wanted to add more depth to requirements). Right now, modders have to use tricks with player.xml, auto-researched technologies, etc. to give layering to requirements.

Having mentioned it, you should look at the xml files in \binaries\data\mods\public\simulation\templates\special\player\. These files define some player and civ specific requirements as well as building/training limits, among a bunch of other things.

I'm putting together the component files in JS to get this to work. Although obviously items will have to wait till they actually exist.

I also came across some interesting code for a 0AD version of another feature I added to GAE in my fork. Does the game already have, probably in mods?, a structure that can move units between 2 points, sort of like Nydus Canals in SC1? There was also a load command that allowed any of a set of structures to dump units from another, like a standard portal network. Since my planned mod is a fantasy one I'd really like to have these options.

I am not sure about these specific features, but Hyrule:Conquest adds a lot of fantasy features to the 0 A.D. engine, so you should check that mod out.

Looked at that thread a bit. Won't be super useful probably unless @The Undying Nephalim comes back. They haven't been active for a month or so.

It seems so, and it would indeed be cool if you could try and have this included in the main game (i.e. make a diff on Phabricator).

I'm going to sleep now but I'm going to try and finish stuff tomorrow for detailed testing. What was the main issue with that diff? Did they not finish or not test or was it GUI stuff?

Am I correct that entity_id_t is functioning in place of pointers for passing stuff to the javascript? The JS code is really hard to understand because without defined variables I can't often figure out exactly what info I'm returning from queries.

Like say I do the query of the units a player has into an array.

Engine.QueryInterface(SYSTEM_ENTITY, IID_RangeManager).GetEntitiesByPlayer(playerID)

Suppose I have the pseudocode of:

Requirements:
  vector<Upgrade*+count> Upgrades;
  vector<Unit*+count> Structures
  vector<Unit*+count> Units
  vector<Item*+count> Items

Then I load each one from the JSON:

// xml/json nonsense to load the 4 vectors
vector<string/count> jsonUpgrades;
vector<string/count> jsonStructures;
vector<string/count> jsonUnits;
vector<string/count> jsonItems;

for (int j = 0; j < jsonunits.size; ++j) {
  for(int i = 0; i < world->faction->units.size; ++i) {
    Unit *check = world->faction->units[i];
    if (jsonUnits.string == check.getName) 
      requirements->addUnit(unit/count);
  }
}
//repeat for other requirement types

In place of unit pointers in my JS vectors/arrays I'd be using the entity ids?

entity_id_t  is a C++ type designating an entity of the simulation.  It's a unique number used to designate an entity; You can query that entity's components by using 

Engine.QueryInterface(entity, IID_Component)

SYSTEM_ENTITY is a special entity_id_t which points to an entity that works kinda like a singleton
