Hello,

In my mod I decided I wanted to remove all the techs except Future Tech and start from scratch. In the CivIVTechInfos.xml file I removed all of the techs from the first <techinfo> to the last </techinfo>, except for Future Tech.

When I tried to start I got a barrage of error messages, one for each tech.

What did I do wrong?

Lots of files have references to those techs, so you need to get rid of all of them as well. For example, many units + buildings are tied to specific techs. Also, civs get free techs, there can be techs in the map file....

I think I removed the free civ techs. I need to erase the units and buildings then?

Restore all the files to normal. Then locate the <disable>0</disable> tag. Change the zero to a 1 for every tech you want disabled.

Thanks! thisismeaninglessstuffsothatmypostislongenoughtopo stwockawocka

All right. I changed the <bdisable> (not <disable>) from 0 to 1 for everything but Future Tech. However the game did not offer to let me research Future Tech when I started a new game. How come?

This was the order I used when making the techs for my Star Trek mod:
1. Add Star Trek techs but not delete epic game techs yet
2. Change requirements of future tech to be on Star Trek tech tree
3. Delete epic game buildings
4. Add Star Trek buildings
5. Remove tech requirements from units
6. Change civ starting techs
7. Remove any other tech references (civics, terrain, features, improvements, resources, promotions, routes, possibly more)
8. FINALLY remove epic game techs

All right. I changed the <bdisable> (not <disable>) from 0 to 1 for everything but Future Tech. However the game did not offer to let me research Future Tech when I started a new game. How come?

Find Future Tech in the assets/xml/technologies file. Find the line that says "prerequisite tech," delete the tech that's there and replace it with NONE.

Beautiful, thanks.
