Making Cradle 3+ fully compatible with the Apolyton Edition

Freight Flag: Per the quote below from Martin Guhmann, there has to be a "freight flag" activated in tileimp.txt in order for trade routes to follow roads:

"Some of the tileimp records contain an additional flag the Freight flag. Just copy it to the according entries in the Cradle versions, so that new trade routes follow the roads"

Accordingly, I've added Freight flags to all the road types in Cradle 5 (see attached example), using the values from AE in all cases, except making some alterations to account for the lower movement rate on Cradle roads vs. AE roads (2 tiles-per-turn vs 3)

New "Citizen" graphic:

The image which accompanied the new "Citizen Concept" entry in the Great Library uses the CtP2 "pick-axe guy" who also appears in the "Worker" and "Specialist" concept images. There's nothing terribly wrong with that, but it definitely doesn't fit the mental image of a "Citizen". Accordingly, I've created three new images which use the CtP1 Farmer as the centerpiece (see attached)

New files: upcp050l (Specialist), upcp070L (Citizen) & UPCP085L (Worker)

Elite Unit Upgrade Info:

Upgrading of Elite Units is controlled by SLIC, and is driven by the discovery of a limited number of Advances (Bronze Working, Barracks, Iron Working, Dark Ages, Gunpowder, Flintlock, Mass Production, Advanced Infantry Tactics, Chaos Theory, Feudalism (Militia Only) & Railroad (Militia Only)). In addition, the upgradeable units have to be in a City, Fort, or Airbase otherwise the code won't "see" them. Unfortunately this information is not specified anywhere, and without advance warning the player will miss out on the opportunity to upgrade many of his Elite Units.

Accordingly, a "notification" comment has been added to the GL Entries of every Advance which drives an Upgrade (see attached).

Chariots appear late in the historical timeline:

Currently the player can get the City State and Oligarchy gov-types before Chariots are available, which is far later than their true historical appearance. This also means it's rarely worth building any.

Although not directly related, this problem was obscured because the "Barracks" Advance is graphically out of place on the Tech Tree (part of the "Engineering" series instead of "Warfare"). Moving it however is problematic since it doesn't have any direct "Warfare" pre-reqs.

Accordingly, Chariots are now a pre-req for Bronze Working (see attachment above), which is close to the true historical sequence. In addition, since Bronze Working is a pre-req for Barracks, this also gives Barracks a firmer place in the Warfare sequence.

Files Changed: Advance.txt, GL.txt, Tech Tree.​

Plunder unit types:

When participating in battle, some of the Wonder units generate "Plunder" (controlled by SLIC), but the type of plunder unit changes after the discovery of certain Advances. And - similar to the situation with Elite Unit upgrades - that information wasn't provided anywhere.

Fortunately the solution is the same. Each Advance which alters the type of Plunder unit now has an entry in the Great Library which describes the change (from unit "x" to unit "y"). The second paragraph in the Bronze Working GL entry (see the attachment to post # 303 above) has an example of the new text.

"Unwelcome invaders" regard hit:

It's fairly common to see the following message in the Intelligence Report window: "This nation is outraged that we continue to move our troops within their borders. To them, we are unwelcome invaders." This is the visible manifestation of a particular type of "Regard Hit", so it's helpful to understand what causes it.
- After a fair amount of testing, I can say that invisible civilian units (such as Diplomats) don't trigger the message, even if they are seen by other stealth units and remain in foreign territory over multiple turns.
- Military units can travel within another nation's borders without negative effect IF they are not spotted.
- Military units DO trigger the message if they enter the other nation's territory and ARE seen (even if they leave on the same turn).

The "North American Tribes":

The "Native American" civilization has been renamed "North American Tribes". One reason is that every city is named after a North American tribe, but equally important is that Cradle includes 3 other civilizations who are also "Native Americans" (in the larger context of "the aboriginal peoples of the Americas"), specifically the Aztecs, Maya, and Inca. Rather than change the underlying code name (which remains "native_americans"), only the translation files have been altered.

AI Intelligence Factor:

According to Protra3211, he changed the AI_INTELLIGENCE_FACTOR in DiffDB.txt to "25" (normally "1") since "All the mods have this changed to 25 and some post it helps the AI." To see how others have handled this, I looked at the AE Mod scenario and they keep it at 1 in the earlier difficulty settings, but then raise it to 25 with "Hard" and "Very Hard" and increase it again to 35 for "Impossible". MoT doesn't change it at all, while AOM uses 25 only for "Impossible".

For Cradle 5, we'll alter the settings to 10 for Medium, 25 for Hard and Very Hard, and 35 for Impossible

TurnsAcceptedForOnePop:

This is a new setting in Const.txt (not previously available in Cradle or even AE) which tells the AI to add Farmer specialists if city growth requires more than the specified number of turns. This flag can also be referenced in the strategies.txt file. The format is: TurnsAcceptedForOnePop ** (choose any number to replace **)

The chief benefit is to reduce the AI's single-minded focus on production (which I've been unable to achieve with other game file settings). Now in Cradle 5 with a value of 40.

TIMP Project:

After completing the City Graphics project back in September, I've been running an extended playtest that's uncovered a few issues along with some under-the-hood improvement opportunities (most have been reported along the way), but otherwise the game has been quite stable and is working largely as intended. Behind the scenes however, work is proceeding on the last big project - Tile Improvements. It's been a multi-faceted and challenging exercise, and there's still a long way to go, but it's time to start pulling back the curtain to give you a look at some of what's been going on.​

[Kull]

Terraform Ocean Button:

Tile improvements are an important facet in the game, and Cradle 5 already features a number of new options in this area. Examples include the new "Trawlers" level and a 4th level for roads. Although the number of SLIC-created tile improvements is essentially unlimited (for example the Natural Wonders feature), those which can be placed by the players (AI and human) are limited by the number of slots in the Tile tab on the Control Panel (bottom right of the game screen).

In the base game the Tile Tab has 3 buttons for the placement of TIMPs, each with 12 slots, and currently most of those are used (34 of 36). The 4th button is fully assigned to Terraforming, and has no open slots. However, the Source code team added a 5th Button ("Terraform Ocean") along with the following message in the Apolyton Edition Readme file: "Added: TerraformOcean button in tile bank. This allows modders to use up to 60 of the 64 available tileimp slots".

Based on that information, I kicked off a large sub-project which aimed to re-name and restructure the TIMP buttons (see before and after button names on the attachment), while also examining ways to greatly expand the number of tileimps in Cradle5.

​

Terraform Ocean Button (con.):

Unfortunately, this particular sub-project came to naught because there's a fundamental difference between "standard" TIMPs and the "terraforming type". When you look at the controlling file (tileimp.txt), a standard TIMP has TWO button location identifiers: "Level" (the row number of the TIMP) and "Class" (one of 12 column names for each of the 3 TIMP placement groups). For example, the "Port" icon (see top of the attachment) is on "Level 1" (first row) in the "Class:OceanATM" group (the 3rd column of the "Ocean" button group).

By contrast, the Terraform group has THREE button location identifiers: "Level" (the row number of the TIMP), "Column" (the column number of the TIMP), and "Class" (the name of the button group). An example of this system is "Terraform Desert" (see bottom of the attachment), the icon for which can be found at "Level 3" (third row) of "Column 0" (first column) in the "Class:Terraform" group (the Terraform Land Button).

The problem is that "standard" TIMP icons will not appear in the Button Bank if they have three location identifiers, and the new "Terraform Ocean" button will not accept any TIMPs that have only two. So the new button only works if you are creating additional terraforming-types, and the only remaining candidates for that sort of activity are the various ocean-type terrains, none of which are being modified in Cradle.

Apologies for the long dissertation, but hopefully this clarifies the limitations associated with the new "Terraform Ocean" button. More to the immediate point, it means my grand project for adding new TIMPs is restricted entirely to the last two remaining "standard" TIMP slots. Disappointing, but there was a silver lining - the research expended in trying to make this work provided a much deeper insight into the workings of the Tile Improvement control files. That will pay big dividends as we proceed.

​

[Kull]

TIMP Control files:

"Big Dividends" eh? Such as? Well, one of the earliest Cradle5 game improvements was focused on revising the Advances associated with Terraforming. As just one example, the ability to remove Dead tiles was now associated with the Tribunal Empire Advance instead of the late-game Conservation:

TERRAIN_DEAD {
TilesetIndex 17
Icon ICON_TERRAIN_DEAD
InternalType: Dead

RemoveAdvance ADVANCE_TRIBUNAL_EMPIRE
TransformRemove {
Time 3
Materials 1000
} 

Seems pretty clear. In fact, all the changes mentioned in that post were made to the terrain.txt file, after which I moved on to other things, confident that all was well. But it wasn't. According to Martin Guhmann, changes to CtP2 tiles require the adjustment of TWO files, "tileimp.txt and terrain.txt, if I remember correctly you have to modify both files."

Uh Oh. And sure enough, the tileimp.txt entry for TILEIMP_TERRAFORM_GRASSLAND still included this segment of code:

TerrainEffect {
Terrain TERRAIN_DEAD
BonusFood 300
EnableAdvance ADVANCE_CONSERVATION
TilesetIndex 1
} 

While you could now transform a Dead Tile into "something else" after Tribunal Empire was discovered, the only option was terraforming it into Grasslands and that would not be possible until Conservation. In other words, nothing had changed. Ugh.

OK, why are there two files, and how do they work? The terrain.txt file identifies a type of tile and provides the basic values (food, gold, movement points, etc) and also lists the Advances which allow this terrain-type to be added and/or removed via terraforming. However, in order to know what it can be transformed into, you need the tileimp.txt file. And THAT had not been modified to match the new changes implemented in Cradle5.

So yes, a big problem, now identified and fixed.​

EDIT: Or.....not. Gah. After running a series of tests to conclusively establish the role of each file, it turns out that part of the above is incorrect.

The tileimp.txt file assigns a "TerrainEffect" to every entry in that file, which includes a line for "EnableAdvance". That code is necessary for non-terraforming TIMPs (such as Farms or Mines), but it has no effect on terraforming - all those Advances are assigned by the terrain.txt file. Which means the Terraforming Advances listed in tileimp.txt are confusing and meaningless. For that reason, I'm going to change them all to the late-game "ADVANCE_HEXTAPUL" (which exists simply as something to research when all other Advances have been discovered)​

[Kull]

"Excludes" tag in tileimp.txt:

This next bit literally made my head hurt, so I'll describe the issue using examples and try to keep it as simple as possible (The good news is that Cradle players can ignore the whole post, since it's primarily of interest to modders). As noted earlier, there are two open slots remaining on the Tile Improvement "button bank", one of which sits between the "Sea Tunnel" and "Maglev" (see top of attachment). Should be easy enough to just create a new tile improvement and plug it right in, yes? Well, no. But to "keep it simple", let's notionally move an existing TIMP (Sonar Buoy) into that spot and walk through the ramifications. But first, we'll look at the Excludes tags in the Maglev entry, to help you understand what they do.

As you can see at the bottom of the attachment, there are two "Excludes" settings, Road and OceanRoad. This refers to a pair of "Class" columns on the Land and Ocean buttons. Looking just at "Road", that column contains 3 slots for building a Road, a Stone Road or a Railroad. When Maglevs assign the "Excludes" tag to the Road column, it means "if you build a Maglev in a tile containing a Road, Stone Road or Railroad, the Maglev will replace that tile improvement". Conversely, if you build a Maglev on any tile containing a TIMP that is NOT excluded, the two will coexist. Which, for example, is why you see Roads in the same tile as Farms and Mines.

Returning to the Sonar Buoy, if that is placed in the "OceanRoad" column, it will need the same "Excludes" values as the Sea Tunnel, meaning it will coexist with all the other ocean-type improvements, instead of replacing them as it does now. In addition, the Sea Tunnel will now REPLACE the Sonar Buoy (and vice versa) instead of co-existing with it.

All of which means that it's going to be a little tricky to utilize the open slot in the OceanRoad column.

TIMPs that can't be pillaged:

One of the new features in AE is the CantPillage flag for TIMPs, and Cradle 5 assigned that to Pastures and Nets. Unfortunately the AI does not "know" what that means, and extensive playtesting has shown that un-pillageable TIMPs cause AI units to sit on them for multiple turns, constantly trying to pillage without success. That means they operate like flytraps, holding AI units in place instead of allowing them to attack or explore.

Anything which adversely affects the AI is a problem, so the flag will be removed from both TIMPs, but the PW costs will also be reduced so it's cheaper to replace them.

The downside of that removal is particularly applicable to Nets, because they are extremely hard to protect. AI naval vessels spend a lot of time in your waters, especially during the initial Exploration phase. The new flag prevented a lot of unnecessary early-game warfare, since the AI tries to pillage any Ocean TIMP they find, even when you have good diplomatic relations. Accordingly, we'll mitigate the issue by removing the CanPillage and CanPirate flags from Coracles, which also means the AI will use them as they should - purely for troop transport and exploration.
