Maybe this is difficult because the algorithm needs to be deterministic. This means that it can generate any pice of map just by the coordinates and the parameters you have set.

I think the idea of silverwarior is great. I would add, that the areas with less creepers and small but near resources could repeat. For me, that's the points I would like to settle out and begin a second base.

Yes I read the instructions in the first post bout the need to manually delete old scenario pack folder but I still gave it a try.

The updates are basically packages with diffs between different versions. The scenario pack update is a diff from version 0.0.0 (no scenario pack) to 0.5.0. Therefore it doesn't apply in the case when scenario pack (like 0.4.4) is already installed. Sure Factorio could see that 0.4.4 < 0.5.0 and 0.5.0 is a complete package (doesn't need any diff) and simply delete the 0.4.4 version and offer the update. That might be the case in the future (it is not so much work). However we wanted to avoid any complications with the first updater version.

I look forward to further updates with great enthusiasm. A bit off topic, but I am so pleased with Factorio, I have been playing it to the exclusion of nearly every single game I own.

Thank you. That is very encouraging to hear.

That is rather pity.

This is doable. The map generator can be represented by two functions:

TilePosition -> GeneratedTile
TilePosition -> GeneratedEntities (fish, resources, enemy bases, etc.)

Both of these functions use the deterministic randomness (internal random generator). The issue I see with making a Lua API for this is the performance. It would have to be tested. And of course once we migrate to LuaJIT it coudl be feasible.

Can this be made by the lua script for different GUIs or just in the begining for all the GUIs?
Because it would be awesome to have a smartphone-like frame arround the PDA item, or an electric circuhit as the background for the soldering iron GUI. (Something new coming in some update of the F-Mod)

Have a look at the data/core/prototypes/style.lua. These values can be changed from the mod in the same way the regular prototypes for entities, items, recipes, etc. are.

This is the direction I think we will take. We already have this for the enemy bases (min distance 100).

The map generator is based on the Perlin's noise. For an overview it is good to imagine that the generator creates a "mountain range". Afterwards the shape of this mountain range is translated into what is on the map. So for instance if a point on the map is "higher than 3000m" then it will be sand. If it is lower than 3000m but higher than 1000m then it will be grass, etc. There is a lot of manual tweaks to make the maps look reasonable. And yes we are aware that the maps are not of a high quality - it is on the list:)

I don't think speed is really an issue, and it should be reasonably fast even in Lua. The thing is that with this one can experiment with maps and stuff like this. And if something is really good, it could be done faster. Also map generator should not be running so much, so it should be fine. (There really are bigger speed concerns than this.)

How do you manage to incorporate all map generation parameters into perlin noise. I have read quite some domumentation on perlin noise lately but I can't seem to figure this out.
Now the size of each patch of gound type (sand, grass, mud) could be afected by changing the height range which belongs to each individual patch.
But how do you controll how often do these patches emerge?

Also how do you controll resource placments and creaper base placments?

The noises we use have 3 basic parameters.
1) Scale
2) Shift
3) Magnitude.

For the purpose of terrain generating, noise for all terrains are generated, every with different settings, and the highest value on the field wins, simple.

Wait you are generating perlin noise for every posible terrain and then compare them between to see which one has higher value at certain location?

Found a bug.

Have two engines coupled, then, select the rear one (and be in it!), and press "R" or your rotate key.

Hyper warp speed!

Love this, even though I know it's unintentional.

Is it compatible with stopping at stations for cargo?

How can I use the game.findentitiesfiltered?? I tried with game.findentitiesfiltered(name="underground-mining-drill",{pos}{pos}) but it says wrong number of arguments.

Oh, I forgot to document it.
