This is an experimental copy for testing Poikilos' issue mirroring system. Note that Gitea's migration tool can import issues, but the "Issues" checkbox is disabled when "This repository will be a mirror" is enabled (it is for this repo).
You can not select more than 25 topicsTopics must start with a letter or number, can include dashes ('-') and can be up to 35 characters long.
* A virtually unlimited number of markers (with alpha for outlines etc) can be placed on the map.
For markers with images that are 32px or below, px is scaled to pt (pt is manually determined for display type and orientation, instead of using default pt which is rather small on mobile devices such as iPhone® 5c)
* No mods are required--Uses Python and PHP (generator.py detects border chunks by setting a flag color as the bgcolor; distinguishes empty chunks from locked database [retries if locked])
* generator.py can loop forever (to keeps certain runtime data to reduce drive reads & writes):
#or run as user that has read & write priveleges to $HOME/chunkymap and your website's minetest folder (or website root if installing chunkymap.php there)
#or to get back to it later with screen -r, instead install screen command (or tmux may work) then run:
* Save jpg or png named as player's index to the players folder of the world to change player's icon on map (index is a number assigned for use with ajax when $show_player_names_enable is false). The index can be found in the player's yml file generated by generator.py.
* Other programs (or echo command) can send signals to generator.py via signals.txt in same folder (which will be deleted after read, so must be created by same user/group)
* to maintain stability of your text editor, save the file, close it, then move/copy it to the directory (or save it as something else then rename it to signals.txt).
* minetestinfo.py's Chunk set_from_genresult expects the following lines (such as from minetestmapper.py or minetestmapper-numpy.py):
Result image (w=512 h=3152) will be written to C:\Users\jgustafson\Documents\GitHub\minetest-chunkymap\chunkymap-genresults\Enliven20170213v7\singleimage.png

('PNG Region: ', [-208, 304, -688, 2464])
('pngMinX: ', '-208')
('pngMaxZ: ', '2464')
('Pixels PerNode: ', 1)
('border: ', 0)
where PNG Region values are left,right,top,bottom respectively.
where required values are Result image dimensions, and PNG Region or xmin,xmax,zmin,zmax.
* Player username privacy: check_players in generator.py intentionally makes up an index and uses that as the filename on the destination, so that ajax can update players without knowing either their id (filename of minetest player file) or display name (listed in the player file)
This should be hard to corrupt since id is used as the indexer for the players dict (however, extra files with no matching entry in the dict will still need to be deleted if they exist)
* games_path, mods_path, players_path, and other subdirectories of the major ones should not be stored in minetestmeta.yml, since otherwise the values may deviate from the parent directories when the parent directories change.
* Keep in mind that gameid (in game.conf in a subgame folder, and world.mt in a world folder) is NOT case-sensitive: for example, minetest_game has the gameid 'Minetest' (first letter capitalized) but the worlds generated by Minetest client have the gameid 'minetest' (lowercase) in their world.mt
* Installing as cron job is OPTIONAL (and NOT recommended):
(schedules update script every minute that runs the py file unless the py file is not complete [may take longer than 1 minute so
requires GNU flock])
* IF you are using a distro such as Ubuntu 14.04 where first line of /etc/crontab is "m h dom mon dow user command" then if you want regular refresh of map then run:
(otherwise first edit the script to fit your crontab then)
(if you are not using /var/www/html/minetest/chunkymapdata, edit chunkymap-cronjob script to use the correct directory, then)
* Other requirements for Windows are below; Requirements for GNU/Linux are anything installed by install-chunkymap-on-ubuntu.sh (for other distros, modify it and send me a copy as a GitHub issue as described below in the Installation section)
* If you are not using Ubuntu, first edit the installer for your distro (and please send the modified file to me [submit as new issue named such as: DISTRONAME installer except instead of DISTRONAME put the distro you made work])
OPTION 2: IF you are using Ubuntu go to a terminal, cd to this directory,
then switch user to the one that will run minetestserver
(since install-chunkymap-on-ubuntu.sh DOES replace "/home/owner" with current user's home [replace-with-current-user.py, which is automatically called by install, will change /home/owner to current user's directory in each script that install copies to $HOME/chunkymap])
* Rename viewchunkymap.php so it won't be overwritten on update if you want to modify it (or anything you want) then make a link to it on your website or share the link some other way.
# The commands below will work if you are using the web installer, or have done mv minetest-chunkymap-master "$HOME/Downloads/minetest-chunkymap" (and if you are using /var/www/html/minetest -- otherwise change that below)
# after you do this, the update script will do it for you if you are using /var/www/html/minetest, otherwise edit the update script before using it to get these things updated
* Add AJAX to update players on canvas (refresh players every 10 seconds)
* Add AJAX to update chunks on canvas (check for new map chunks every minute)
* Fix static html version of map (echo_chunkymap_table() php function) -- see viewchunkymap.php
* Zoom in and out
* optionally echo name of world that was detected by the scheduled py file
* shows player location (can optionally show only first characters of name, for privacy; there is no saved setting yet, so to adjust, you must change the value of $nonprivate_name_beginning_char_count in chunkymap.php)
* Ghost players if they stay in one spot long enough (see $player_file_age_idle_max_seconds in chunkymap.php)
* Hide players if they stay in one spot long enough (see $player_file_age_expired_max_seconds in chunkymap.php) avoiding logout detection, and not requiring mods
