**_mTimer_ is a mod for showing ingame and reallife times and periods**

## Description

*mTimer* is a mod that allows players to individually configure and show a timer as permanent HUD element that automatically updates every second. The timer can show the real-world time and the ingame time as well as the current play session starting time and duration in freely configurable formats.

Use it on your public server to give your players additional value (players can individually hide the timer if they want) while being on your server or use it in your singleplayer world to stay informed or – when creating creative content for others to watch – give your viewers a hint on when the footage was recorded.

The mod is game-agnostic and does not have any dependencies. The mod only interfaces with Minetest’s *HUD API*, the *player meta data API* and the *Formspec API*.

## Configuration

The timer display and settings are entirely configured on a per-player basis via configuration formspecs. Configurations are set when leaving the formspec via the buttons or when pressing enter or clicking the apply button (where available). Pressing the escape key cancels the changes.

For opening the main menu simply enter the `/mtimer` chat command. From the main menu all configuration formspecs are accessible.

Simply click the button of the option you want to configure.

Configuration formspecs can be accessed directly by providing the respective parameter to the `/mtimer` chat command. Run `/mtimer help` to see a list of available parameters. You might need to bring up the console (F10 by default) to see all available parameters because the chat display might be too small.

### Variables

Some formspecs allow you to use variables. The variables and their current (i.e. the moment when opening the formspec) values are shown below the input field.

Simply use the variables as shown. For example, to use the day name in the formspec shown above simply enter `{dname}`. Using unknown variables is possible. Those variables are rendered literal. So Entering `{foobar}` renders to “{foobar}” in the output.

Using a string being a variable is not possible (`{foobar}` will always render to it’s value if it is a valid variable). Using the same variable multiple times is possible.

### Confirmations

Pressing enter in an input field applies the changes. Not all formspecs have input fields. Sometimes there only schemes or just buttons.

Using those formspecs is the same except setting things works instantly. So by clicking the bottom right on the scheme in the formspec below directly places the timer there.

Where needed, apply buttons are placed. So instead of having to leave the formspec via the navigation buttons at the bottom to apply the changes simply click the apply button to have the value applied.

In the timer format configuration formspec shown above a text area is used where pressing enter goes to a new line so a button for applying the changes is shown.

## Custom Timer

mTimer comes with a freely configurable custom timer that can run in three different modes and shows its current state and time as applicable. The formats for the three states can be configured individually.

The four time unput fields on the middle left are used for days, hours, minutes, and seconds and the table with the variables shows the set value and not the current value because the current value changes depending on the timer state and mode.

![Custom Timer](screenshots/custom_timer.png)

In *Countdown* mode the custom timer counts down from the time that was set using the time input fields. In *Timer* mode the custom timer counts up to the value that was set. And in *Continuous Run* mode the custom timer counts up from when it was started, adding the time that was set to the starting point calculation.

After the custom timer was set up it needs to be started. Starting (as well as stopping or restarting) it is done using the defined chat commands.

```
/mtimer ctstart    -- Start the timer if not running
/mtimer ctstop     -- Stop the timer if running
/mtimer ctrestart  -- Restart the timer if running
```

If the custom timer finished the format changes to the “finished” value. Please note that the timer is still running if this message is shown. To stop the timer you need to invoke the corresponding chat command. Only if the “stopped” format is used the timer is actually stopped (i.e. most of it’s logic isn’t running).

## Default configuration (interesting for server admins)

The default configuration is loaded on server start and applied when a new player joins or an already existing player sets any (or all) of the mTimer values to the default value via the main menu or one of the specific dialog formspecs.

The mod tries to load the configuration from least to most mod specific locations:

1. Default `minetest.conf` that is used to load the server
2. From `_mtimer.conf` in the served world’s directory
3. Built-in default setting defined by the mod’s author

There is intentionally no `settingtypes.txt` because the mod is meant to be configured by the individual players. The following options can be set in either `1.` or `2.` without changing the mod’s code. After that a server restart is necessary.

```ini
mtimer_color = #ffffff
mtimer_hud_element_size = 1
mtimer_position = bl
mtimer_timezone_offset = 0
mtimer_visible = true

mtimer_host_time_format = {24h}:{min} ({isodate})
mtimer_ingame_time_format = {24h}:{min}
mtimer_real_time_format = {24h}:{min} ({isodate})
mtimer_session_duration_format = {hours}:{minutes}
mtimer_session_start_time_format = {isodate}T{isotime}
```

The timer format and the HUD element’s offset can’t be set because those values need special formatting that can’t be done using Minetest’s settings API right now. Namely a serialized table for the offset and a string with newlines

## Known Issues

### Formspecs Look Weird

On very small screens the configuration formspecs might look very crammed with text being cut off or overlaying other text. This is due to how formspecs work and is not fixable without massive Minetest engine changes.

Same in the other direction: On very large screens the formspecs seem unnecessary huge with much empty space. Same here: This is not fixable without re-implementing formspec generation from scratch in Minetest.

mTimer was tested with resolutions from 1024×768 up to 2560×1440 with 20px font and GUI scaling of 1.5. Since different font sizes and GUI scaling are somewhat broken in Minetest when it comes to formspecs the later was usable but did not look that good.

### Formspec Language Does Not Match Game Language

Simple: The mod was not translated to the language you’re using. Feel free to translate it and file a pull request. I’d be happy to merge it.

Currently German (`language = de` in `minetest.conf`) and Italian (`language = it`) are supported as translation language and English being the default and Italian being slightly out of date.
