Use multiple events and other Civ2 files to make your scenario do some things you probably never thought about.

Introduction

Here's everything you need to know about the use of multiple events. As a user of this tip, should you find any errors, please contact the tip's author - Allard Höfelt - setting out your comments. Feel free to add this to your sites/guides providing credit to the author. Warning - not all of the examples have been tested.


New possibilities

Changing specific Civ 2 files during a game can give the designer huge advantages. Some of the most obvious I have written down in this document. The less obvious ones are scenario-specific.

The use of this allows a whole step ahead, with endless new possibilities. I'm looking forward to play the first scenario to use it.

However, remember when using these that they are pre-built. They cannot be affected by gameplay.


Benefits of Switching Rules.txt Files Midstream

Switching RULES.TXT allows you to change:

  • Civ personalities. For example, in a war scenario, the AI is cautious at first, but gets more aggressive. This is very useful!
  • Building/city styles (one of the ancient city styles to another)
  • Caravan items' names halfway
  • Terrain properties. For example, you could simulate some bad harvests.
  • Names of governments. Maybe you don't need a revolution any more...
  • Strength and names of units, allowing unit strengths to change over time
  • Expiration of wonders. You could reactivate a wonder that expired.
  • Road movement multiplier. For example, you could simulate bad roads.


Benefits of Switching Events.txt Files Midstream

Switching Events.txt allows you to change:

  • Events, and allows unlimited events. Note however that things such as NEGOTIATION should be repeated in every events file that you use!
  • Give units/money to player every turn or so, but STOP after a while (i.e. don't repeat it in next events)
  • Same thing: MAKEAGRESSION every turn until end of events


An Example

Consider one of my scenarios, "The Golden Age of the Republic". In it, the Dutch make war with the Spanish until 1648, then stop the war. Then, there are four wars with England and one with France and Germany. The way it is done now is that I use a MAKEAGRESSION every 4 turns (not every turn to save events) (so turn 4, 8,...) until 1648. Also I had to allow open negotiation with Spanish to allow them to make peace (and eventually become allies) with them.

But here's how it could be done instead. Make two events, one before 1648, one after. In the part before, don't allow negotiation, set makeagression to -1. In second part, allow negotiation. It's that easy.


Switching Artwork Files Midstream

You can do a similar thing with all of the art files.

Units

Switching Units.gif allows you to change the way units look, so they change look during play.

Eliminate obsolete units and replace them with others (requires a change in RULES.TXT too)

Terrain

Switching Terrain1.gif and Terrain2.gif allows you to change:

  • The look of terrains. For example, you could simulate winter/summer, simulate bad harvests, periods without rain, etc.
  • Change rivers. In a scenario around a river (Amazon) simulate pollution, or mud.
  • Change mountains. In winter, mountains should look snowier than in summer...

Icons

Switching Icons.gif allows you to change the look of buildings and wonders. For example, suppose a wonder is destroyed during gameplay. You could give the icon another "look".

You can also now modernize the look of buildings if covering a large time span. Go from stone-age buildings to advanced classical icons. Change the look of your scenario with new borders etc. Great to use some variety and keep the interest of the player.

Cities

Switching cities.gif allows you to change;

  • The building styles of nations. Great to modernize a culture.
  • The flags of nations (and even the colour, although I wouldn't advise this).
  • The icon for airports. You can for example hide them in the first events (in non-obvious places to avoid it being "discovered") and change it to normal icon later.


There are of course tons of other uses, but those demand your creativity!


A Quick "How To" Guide

I will explain my advice on how to do it in this example. First, make an identical EVENTS.TXT and EVENTS1.TXT. Then add other events as EVENTS2.TXT, EVENTS3.TXT, etc. Somehow download the useful program DELEVENT.EXE supplied with the Fantastic Worlds add-on, but not with MGE. Put it in your scenario folder and include it in the ZIP (just a few KB). Write this BAT file and name it 1to2.bat:


@ECHO OFF

COPY EVENTS2.TXT EVENTS.TXT

(and include the other ones too)

COPY TERRAINB1.GIF TERRAIN1.GIF

COPY TERRAINB2.GIF TERRAIN2.GIF

COPY RULES2.TXT RULES.TXT

(etc.)

DELEVENT %1


Explanation: Events2.txt replaces events.txt (that is why you had to use an identical events and event1). Delevent is the most important (only if you use events). It erases the events inside the savegame. The %1 is the name of the savegame. To start the batch file, you should type 1to2 MYSAVE.SAV (where mysave is the name of your saved game). This is essential, don't forget to say it to the player before switching.

Now, similarly create 2to3.bat and any other XtoY.bat files you may need.

The files you should now have are, assuming you want to switch three times, and I'll only use TERRAIN1 and TERRAIN2, are:


TERRAIN1.GIF TERRAIN2.GIF

TERRAINA1.GIF TERRAINA2.GIF (the same as terrain1 and 2)

TERRAINB1.GIF TERRAINB2.GIF

TERRAINC1.GIF TERRAINC2.GIF

TERRAIND1.GIF TERRAIND2.GIF


I'll again briefly explain what the program does to these files. It copies terrainb1 and b2 to terrain1 and 2. The terraina1 and a2 file remain unchanged, so are the terrainb1 and b2.

Now, create another BAT file. Name it RESET.BAT.


@ECHO OFF

COPY EVENTS1.TXT EVENTS.TXT

COPY TERRAINA1.GIF TERRAIN1.GIF

(etc., etc.)


It should be done now. Don't forget to inform the player as much as you can. You have enough events now, so to avoid any difficulties, do as much as possible in the events to inform the player what to do. Make it clear that the player has to go to DOS, and in the right directory type 1to2 MYSAVE.SAV. The player should, however, have no problems with this; it is relatively easy compared to playing many of the scenarios that I feel are going to use this approach.
