1) place the sprites in [CtP2 folder]\ctp2_data\default\graphics\sprites

2) place the tga's in [CtP2 folder]\ctp2_data\default\graphics\graphics

3) edit [CtP2 folder]\ctp2_data\default\gamedata\spriteID.txt. E.g. if you have a Chariot unit add the line UNIT_CHARIOT2 100. Both the UNIT-name and the number need to be unique and the number needs to be the same as the number as the sprite (same as in CtPI). So in my example you'd need to call you sprite 'Gu100.spr'.

4) edit [CtP2 folder]\ctp2_data\default\gamedata\uniticon.txt. For my Chariot example it might look like this (I copied this for the CtPII Cannon unit):
ICON_UNIT_CHARIOT { FirstFrame "UPUP100L.TGA" Movie "NULL" Gameplay "UNIT_CHARIOT_GAMEPLAY" Historical "UNIT_CHARIOT_HISTORICAL" Prereq "UNIT_CHARIOT_PREREQ" Vari "UNIT_CHARIOT_STATISTICS" Icon "UPUP100A.TGA" LargeIcon "UPUP100L.TGA" SmallIcon "UPUP100B.TGA" StatText "UNIT_CHARIOT_SUMMARY" }

5) Then add the appriopriate texts to the bottom of [CtP2 folder]\ctp2_data\english\gamedata\Great_Library.txt. Example:

code:

---

[UNIT_CHARIOT_PREREQ]
Requires:
< L : DATABASE_ADVANCES,ADVANCE_THE_WHEEL > The Wheel < e >
[UNIT_CHARIOT_STATISTICS]
Attack: {UnitDB(UnitRecord[0]).Attack / 100}
Ranged: {UnitDB(UnitRecord[0]).ZBRangeAttack}
Defense: {UnitDB(UnitRecord[0]).Defense / 100}
Armor: {UnitDB(UnitRecord[0]).Armor / 100}
Damage: {UnitDB(UnitRecord[0]).Firepower}
Vision: {UnitDB(UnitRecord[0]).VisionRange}
Movement: {UnitDB(UnitRecord[0]).MaxMovePoints / 10000}
[END]
[UNIT_CHARIOT_SUMMARY]
Ancient Flanking Unit
[END]
[UNIT_CHARIOT_GAMEPLAY]
Due to it's large attack factor the Chariot is one of the most formidable Ancient 
attack units and, though slower, only surpassed by the < L : DATABASE_UNITS,UNIT_ELEPHANT_WARRIOR > War Elephant < e > . 
Also, it's a flanking unit so it can provide support to other units during combat.[END]
[UNIT_CANNON_HISTORICAL]
The Chariot was one of the most important Cavalry units of the Ancient Age.
[END]

Edit: I had to change this a little 'cause the script was screwing everything up but you can look at the other entries of the Great_Library file yourself and do it properly.

6) Add an entry to [CtP2 folder]\ctp2_data\default\gamedata\Units.txt. It might look like this:

code:

---

Now start up the game and prey it works (Yes, it's quite a process, but once you get the hang of it, it probably won't be too difficult or time-consuming).

Hope that helps in any way,

I'll keep toying with it and see if I can figure out what else I need to change... I feel like I'm close.

Never mid. I figured it out. Sprite referneces in CTP2 are not to be made in SpriteID.txt. This will cause an error message. Sprite references should now be made in the the file newsprite.txt, which is also located in the "gamedata" directory and looks very similar in content. Apparently, they've devised a separate location for adding new units.

That's very good to hear. Now if you could just tell us how exactly you solved that first error (what section of what text file you changed), that would be a great help to other people trying to add units to the game.
