Scaling Demo 4x for Minetest

Based on Aug 31, 2019 commit of minetest_game. Created with the corresponding master branch version of minetest. When used with the stable-5 branch, errors about invalid background elements show up when using the inventory, but it still appears to work. No guarantees though.

This is a technology demo to give an example of what happens when the player character is scaled up by 4x, which gives the effect of shrinking all the nodes to 1/4th their original size.

To use this game with Minetest, place this repository in minetest/games directory.

Notes and Cautions:

• Must use Creative mode to get reasonable selection distance.

• Must turn off damage—normal jumps at 4x physics cause fall damage.

• Vegetation has been disabled, since most plants are now too small.

• Caves and dungeons have also been disabled, since they're now too small to enter.

• Stairs and walls mods are no longer necessary, so have been deleted.

• The standard door is the only other item that has also been scaled by 4x.

• Basic terrain textures are scaled to maintain the look of the unscaled minetest game. Other textures will likely look too small.

• Mapgen parameters really need to be scaled and tuned to look right at 4x, but my attempts haven't turned out too well.

• No digging aids are currently provided. One could try the digall mod. Note that one original meter block is now 64 blocks, so digging and placing are now very tedious.

Quarter node house example:

I thought it would be interesting to show what can be done with smaller nodes, so I made a scale model of my house, with a full interior.

I have added the bakedclay mod to this game repo, to get more colors to play with, however I removed its stairs nodes and scaled the textures. I also had to scale some more default textures and I needed to update the steel_door texture to get rid of the window.

I have included the schematic called schems/house_example.mts. To use, copy this file to worlds/yourworld/schems/house_example.mts and use your choice of schematic loading software, such as worldedit to load. Warning: Only use this mts file with Scaling Demo 4x!

However, make sure you have enough flat space before loading, it's dimensions are about 50 x 80 with a height of 30 nodes.

Lighting: Minetest only propagates the light from lamps a short range, which makes it very difficult to light a room at 4x scaling. To help get around this I have provided the fill_light mod, which allows placing fill lights that can then be made invisible. See mods/fill_lights/README.md for details. When first placing fill lights I recommend setting 'smooth_lighting = false' to better understand how the lighting works.
