Adding more islands [LUA map script]

[Vilde321]

Hey! Firstly I'm sorry if this isnt supposed to be here, but I figured since it's LUA it propably should be here!!

I am completely new at map scripting, and I have done some sort of script (by copy pasting and looking at other people's scripts), where there are only basic settings enabled like "Tectonic islands", "Continent Grain" and so on..

What I really want is more islands, and I really cannot find a way to do that by myself (been looking for so long to find a solution but I just cannot understand anything and cannot find proper tutorials for this) ..

So basically, is there any way for making the map generator generate more islands for my map? (and possibly any tutorial that I've missed? Im willing to learn..) Or just making my continents have more coast? These are the major things I really wish to have in my script, since I love coastal maps with islands that still have enough ocean to make it interesting and make people isolated for the early game..

Also any info on Player starts? possible to make it so all players start on their own continent..?

I'm really sorry if someone didn't get my points or if I'm just being an idiot here, I just really wish someone could help me


My whole script is here, please don't laugh at it... atleast not too much ;__;

Your best bet would be look at any of the "Plus" map-scripts, where more islands are generated to put the City States on.

There's only so much you're going to be able to do by changing parameters to the standard functions. At some point you're going to have to write custom versions (like some of the map scripts do) and/or delve into AssignStartingPlots.asp - the latter is not for the faint-hearted, as it's the most complex Lua file in the entire game by a long margin.

Okay thanks for pointing me in the right direction.. It's been a bit confusing since I'm only experienced in C# and Java, so this is really new for me.

I'll look at those and if I know myself at all I'll propably go and try to write those custom functions or something.. It's too bad there's no tutorials though..
For now the islands is what I need the most, so I'll just try that first.

Thanks again!

The tutorials are written by CfC members, so if/when you solve your problems, don't forget to write the process/solutions up and contribute it as a tutorial for others to follow at a later date
