Thread: Looking for 474~ Map & Heightmap/Heightfield for a Minecraft recreation project!

In the meantime, I guess I might as well explore how the client calculates heights, and attempt to get that saved to a text file or something. This could get interesting...

We have found some things that have gave us a huge step forward. We have created a heightmap via a 2d map viewer posted within these forums. There are a few things to be worked on still though, so any little bit helps.

For extended detail on this, for anyone who wants to mess with it themselves, we've modified this [Only registered and activated users can see links. ] to display the heights rather than textures, resulting in significantly more useful data. This is done through turning values 0 to -2040 (max RS world height) into 0 to 255 (max MC world height). This was achieved using the cache provided in the [Only registered and activated users can see links. ].

The next step is to have the 2D Map Viewer export the entire map to an image file, or each chunk of tiles to its own file (which can then be stitched together). Images below.

Heightmap (screenshot from client) - only brightness matters, colour is irrelevant.


WorldPainter - by importing the heightmap above into WorldPainter, a world is generated (in this case, at 200% scale - 1 RS tile = 2 MC blocks).


Minecraft - and here is a resulting screenshot ingame.


The snippets above include all the data we've attempted to render in WorldPainter so far - once we've exported the entire map we can then load it all up in one go. We will also need to determine more realistic height parameters, as having land near bedrock with aspects of the world touching Minecraft world height is unrealistic (there are caves and stuff in RS).

If you are interested in helping, respond below and we'll provide the code changes to achieve this.

Update: We're still looking for a 474 heightmap!

We have determined the Enrisep map is from before June 2006, so we still need to try and get a 474 map going. As of right now, any 317loading474 result in a loop of the following two lines.

Requesting file CacheFileDescriptor(CacheIndex(id = 4, size = 3536), 617, 8166, 8868)
Requesting file CacheFileDescriptor(CacheIndex(id = 4, size = 3536), 616, 7073, 8861)

This eventually causes the Map Viewer to run out of memory.

So far we've downloaded over 600mb worth of caches (not to mention even more clients, servers and more). Actual 474 caches are in the new format, so our 317+ map viewer can't load it.



cache_474 is loaded below - as you can see, entire chunks are missing. From recent research, I've learned that this has something to do with the encryption added in the 400s.




HOWEVER, onto actual progress. Below you can see examples of the entire RuneScape January-May 2006 map loaded on a Minecraft Dynamic Map. With and without pathing/building outlines.









(black patches are just lighting issues from an editor I used to add the pathing overlay, the dynamic map makes them look worse than they are)

Everything you see is perfectly scaled in both sizing and depth, so going down the hill on tutorial island is realistic. While for paths and stuff we might have to tweak landscape so players can actually walk up it (landscape smoothing is very strong in RuneScape but.. well, blocky in Minecraft) in general this is AWESOME and significantly better than doing the whole landscape from scratch.

Next step is to either try and fix the loops with 317loading474, or to mess around with extracting the maps from 474 and loading them ourselves into a 317 cache.

        totalRegions = stream2.readUnsignedWord();
		j1 = totalRegions;
        mapIndices1 = new int[j1];
        mapIndices2 = new int[j1];
        mapIndices3 = new int[j1];
        for(int i2 = 0; i2 < j1; i2++)
        {
            mapIndices1[i2] = stream2.readUnsignedWord();
            mapIndices2[i2] = stream2.readUnsignedWord();
            mapIndices3[i2] = stream2.readUnsignedWord();
        }

also iirc -400 height is sea level on rs maps.

Honestly, I've explored hundreds of pages on these forums so I don't know for sure if cache_474 is from you, but I'm willing to try your suggestion anyway.

However, could you provide more context to that code? Here's what the Map Viewer I'm using has at the moment.

DataBuffer b = config.entry("map_index").buffer();
int count = b.length() / 7;

regionHash = new int[count];
regionObjectMapIndex = new int[count];
regionLandscapeIndex = new int[count];
regionPreload = new int[count];

for (int reg = 0; reg < count; reg++)
{
regionHash[reg] = b.getShortUnsigned();
regionLandscapeIndex[reg] = b.getShortUnsigned();
regionObjectMapIndex[reg] = b.getShortUnsigned();
regionPreload[reg] = b.getUnsigned();
}

I'll be playing around with it myself while waiting for your response. And thanks for the water level information, that'll definitely come in handy!
