Different Tech Tree

[apiquinamir]

I tried to implement my own tech tree into a modpack I am making and the game will not accept the new one. Why is this happening?

[Cam]

There are several possible reasons for this. By 'not accept' does it crash? Which version of Civ2 are you using (the extra three slots - U1, U2, and U3 sometimes do not work as intended)? Did you alter 'Future Tech'?

If the game crashes, it's likely you have a technology loop, where two advances are prerequisites for eachother.

Can you post your tech tree? I might be able to make the corrections.

apiquinamir,

It would appear as though you've simply deleted technologies from the list that you don't want to include, rather than giving them the prerequisites "no, no". The computer is searching down lines trying to locate the 90th line down for instance for "Future Tech", which has been brought up the file's order as there have been so many earlier text lines deleted. You would be better served by keeping the existing structure, don't delete lines, but instead give any unwanted advances, the "no, no" prerequisites.

It is also unconventional to start changing the codes for the advances (e.g. the first tech being "Adv" instead of the conventional "Afl"). If you are having persistent problems with your rules.txt (having taken care of the first point about not deleting lines) you may also want to revert back to the old codes for advances, even though "Afl" is not an abbreviation for Advanced Iron Working.

[apiquinamir]

After changing all of the different problems listed in the previous post, it still won't work.

Here's the FW/MGE version of my Imperialism Tech Tree. You are welcome to use it(probably needs a little balancing in relation to Government techs. I tried to position the techs optimally so Iron Railroad Bridge=bridges over rivers, Compound Steam Engine=Forts, Oil Drilling=+1 Colosseum happiness, Breechloading Rifle=Barracks Sold Off, Spinning Jenny=No more techs in huts, Machine Guns=Barracks sold off, Square Set Timbering=Increased Temple Happiness, Streamlined Hulls=+1 Naval Movement, Chemistry=Free Advance, High Pressure Steam Engine=Railroad Building, Mechanical Reaper=Farmland Squares, 20th Century=Future Tech. You will need to make an advance in the "Tra" field if you want to use all the trade options in the game, though. If you are using Conflicts in Civilization or the Original version you will need to delete the Extra Techs at the end and I think this will work in Test of Time.;-)

BTW, the "The" slot which I did not use=+1 Cathedral Happiness. I think that pretty much sums up the effects of techs on the CivII tech tree.
