# advmarkers
# advmarkers (non-CSM)
A marker/waypoint CSM for Minetest, designed for use with the [marker] mod.
# Do not release yet, still WIP
To display markers, the server currently needs the [marker] mod installed,
otherwise "command not found" errors will be displayed, as CSMs cannot currently
create HUDs on their own.
A marker/waypoint mod for Minetest.
Unlike the [CSM], this mod does not require the [markers] mod to be installed.
## How to use
`advmarkers` introduces the following chatcommands:
- `.mrkr`: Opens a formspec allowing you to display or delete markers.
- `.add_mrkr`: Adds markers. You can use `.add_mrkr x,y,z Marker name` to add markers. Markers are (currently) cross-server, and adding a marker with (exactly) the same name as another will overwrite the original marker. If you replace `x,y,z` with `here`, the marker will be set to your current position, and replacing it with `there` will set the marker to the last `.coords` position.
- `.mrkr_export`: Exports your markers to an advmarkers string. Remember to not modify the text before copying it. You can use `.mrkr_export old` if you want an export string compatible with older versions of advmarkers (it should start with `M` instead of `J`). The old format will probably not work nicely with the planned server-side mod, however.
- `.mrkr_import`: Imports your markers from an advmarkers string (`.mrkr_import <advmarkers string>`). Any markers with the same name will not be overwritten, and if they do not have the same co-ordinates, `_` will be appended to the imported one.
- `.mrkrthere`: Sets a marker at the last `.coords` position.
- `/mrkr`: Opens a formspec allowing you to display or delete markers. If you give this command a parameter (`h`/`here`, `t`/`there` or co-ordinates), it will set your HUD position to those co-ordinates.
- `/add_mrkr`: Adds markers. You can use `.add_mrkr x,y,z Marker name` to add markers. Markers are (currently) cross-server, and adding a marker with (exactly) the same name as another will overwrite the original marker. If you replace `x,y,z` with `here`, the marker will be set to your current position, and replacing it with `there` will set the marker to the last `.coords` position.
- `/mrkr_export`: Exports your markers to an advmarkers string. Remember to not modify the text before copying it. You can use `.mrkr_export old` if you want an export string compatible with older versions of advmarkers (it should start with `M` instead of `J`). The old format will probably not work nicely with the planned server-side mod, however.
- `/mrkr_import`: Imports your markers from an advmarkers string (`.mrkr_import <advmarkers string>`). Any markers with the same name will not be overwritten, and if they do not have the same co-ordinates, `_` will be appended to the imported one.
- `/mrkrthere`: Alias for `/mrkr there`.
If you die, a marker is automatically added at your death position, and will
update the last `.coords` position.
@ -27,6 +27,7 @@ advmarkers temporarily stores this position, and you can set a temporary marker
at the `.coords` position with `.mrkrthere`, or add a permanent marker with
`.add_mrkr there Marker name`.
