If you want to make maps just for E4X (I.e. you don't mind not being able to play the maps without the mod), I would highly recommend using the E4X Galaxy Forge tool. It will allow you to manually place specific E4X planets like Cryo worlds, and even has some additional random types.
Will Galaxy forge include the planet types that exist with the enhanced 4x mod? Example: if i place a planet and set the type to "random" short and sweet when the game loads the map will it only roll the dice for rebellion and its DLC's planet types or will it also roll for the mod planet types? like cryo planets etc. Because i already do not see them in the list of planet types in galaxy forge but when changed into the game E4X might be implemented then? if not can I implement them into galaxy forge easily?
In theory it depends on the mod, but chances are virtually all mods will include their new planets in the random planet lists, so the random planet types in the default galaxy forge should work for most mods (and give you a chance at getting the new planets).
(the most important to me at this time) i am making a map that exists to be inherently random. I control gateways and paths but almost all of the planets are set to random types. this being said I need to know what types of planets are entail with these "random" settings. Example: I place a "random truefair" now what the heck does true and fair entail? also weighted boggles my mind. This is the list of options i would like explained if you would be so kind:
The only difference between planets/random planet lists and the fair version is that fair planets always have a fixed set of resource extractors and militia, and often have their planet bonuses removed. They are used only in the competitive versions of maps to ensure that say any two Volcanic planets are equal, rather than one have 3 metal asteroids and a lot of militia versus another player who got one with 4 metal asteroids and a weaker militia.
Includes most possible planets, but I think it favors basic colonizeable planets.
random vs. random fair vs. random true vs. random true fair
Random is what you most likely think of random, each possible planet is in this list and each has an equal chance of being placed. Random True is like random colonzieable except it has to be a "True" planet, I.e. no asteroids or gas giants, but things like Terrans, Deserts, Ice etc.
random special vs. random special fair
Pretty similiar to random uncolonizeable, but with some things like dead asteroids and possibly wormholes thrown in.
weighted colonizable vs. weighted colonizable fair
Anything weighted just means certain planets are more likely to be picked than others. I don't remember the exact weights but in E4X things like Industrial planets are less likely to appear than say ice planets.
"occupied planet" does this start with the defenses and militia that normally accompany an occupied planet or do i have to double click the "occupied planet" and add the template for an occupied planet?
Usually planets will come with their default militias if they are unowned, unless you enable the "Disable Default Templates" option in the group editor for that planet. Occupied might be different though, since its kind of special, so you might need to test it yourself.
lastly "moon" i hear that is just the dwarf planets. can someone confirm?
It is, in the Rebellion beta Dwarf planets were moons, but that was changed because people thought Dwarf planets made more sense.
Also FYI, if you open the GalaxyScenarioDef file for the mod you're using with the map in notepad (or just the E4X Galaxy Forge's file in would work), you can see the planet lists yourself, among lots of other things.
