A full HUD bar represents 100%, an empty HUD bar represents 0%. +* The current value must always be equal to or smaller then the maximum +* Both current value and maximum must not be smaller than 0 +* Both current value and maximum must be real numbers. So no NaN, infinity, etc. +* The HUD bar will be hidden if the maximum equals 0. This is intentional. +* The health and breath HUD bars are hardcoded. + +These are soft rules, the HUD bars mod will not enforce all of these. +But this mod has been programmed under the assumption that these rules are followed, for integrity. + +## Adding a HUD bar +To make a new HUD bar known to this mod, you need … + +* … an image of size 2×16 for the bar +* … an icon of size 16×16 (optional) +* … to register it with `hb.register_hudbar` + +### Bar image +The image for the bar will be repeated horizontally to denote the “value” of the HUD bar. +It **must** be of size 2×16. +If neccessary, the image will be split vertically in half, and only the left half of the image +is displayed. So the final HUD bar will always be displayed on a per-pixel basis. + +The default bar images are single-colored, but you can use other styles as well, for instance, +a vertical gradient. + +### Icon +A 16×16 image shown left of the HUD bar. This is optional. + +### `hb.register_hudbar(identifier, text_color, label, textures, default_start_value, default_start_max, default_start_hidden, format_string)` +This function registers a new custom HUD bar definition to the HUD bars mod, so it can be later used to be displayed, changed, hidden +and unhidden on a per-player basis. +Note this does not yet display the HUD bar. + +The HUD bars will be displayed in a “first come, first serve” order. This mod does not allow fow a custom order or a way to set it +manually in a reliable way. + + +#### Parameters +* `identifier`: A globally unique internal name for the HUD bar, will be used later to refer to it. Please only rely on alphanumeric characters for now. The identifiers “`health`” and “`breath`” are used internally for the built-in health and breath bar, respectively. Please do not use these names. +* `text_color`: A 3-octet number defining the color of the text. The octets denote, in this order red, green and blue and range from `0x00` (complete lack of this component) to `0xFF` (full intensity of this component). Example: `0xFFFFFF` for white. +* `label`: A string which is displayed on the HUD bar itself to describe the HUD bar. Try to keep this string short. +* `textures`: A table with the following fields: + * `bar`: The file name of the bar image (as string). This is only used for the `progress_bar` bar type (see `README.txt`, settings section). + * `icon`: The file name of the icon, as string. For the `progress_bar` type, it is shown as single image left of the bar, for the two statbar bar types, it is used as the statbar icon and will be repeated. This field can be `nil`, in which case no icon will be used, but this is not recommended, because the HUD bar will be invisible if the one of the statbar bar types is used. + * `bgicon`: The file name of the background icon, it is used as the background for the modern statbar mode only. This field can be `nil`, in which case no background icon will be displayed in this mode. +* `default_start_value`: If this HUD bar is added to a player, and no initial value is specified, this value will be used as initial current value +* `default_max_value`: If this HUD bar is added to a player, and no initial maximum value is specified, this value will be used as initial maximum value +* `default_start_hidden`: The HUD bar will be initially start hidden by default when added to a player. Use `hb.unhide_hudbar` to unhide it. +* `format_string`: This is optional; You can specify an alternative format string display the final text on the HUD bar. The default format string is “`%s: %d/%d`” (in this order: Label, current value, maximum value). See also the Lua documentation of `string.format`. + +#### Return value +Always `nil`. + + +## Displaying a HUD bar +After a HUD bar has been registered, they are not yet displayed yet for any player. HUD bars must be +explicitly initialized on a per-player basis. + +You probably want to do this in the `minetest.register_on_joinplayer`. + +### `hb.init_hudbar(player, identifier, start_value, start_max, start_hidden)` +This function initialzes and activates a previously registered HUD bar and assigns it to a +certain client/player. This has only to be done once per player and after that, you can change +the values using `hb.change_hudbar`. + +However, if `start_hidden` was set to `true` for the HUD bar (in `hb.register_hudbar`), the HUD bar +will initially be hidden, but the HUD elements are still sent to the client. Otherwise, +the HUD bar will be initially be shown to the player. + +#### Parameters +* `player`: `ObjectRef` of the player to which the new HUD bar should be displayed to. +* `identifier`: The identifier of the HUD bar type, as specified in `hb.register_hudbar`. +* `start_value`: The initial current value of the HUD bar. This is optional, `default_start_value` of the registration function will be used, if this is `nil`. +* `start_max`: The initial maximum value of the HUD bar. This is optional, `default_start_max` of the registration function will be used, if this is `nil` +* `start_hidden`: Whether the HUD bar is initially hidden. This is optional, `default_start_hidden` of the registration function will be used as default + +#### Return value +Always `nil`. + + + +## Modifying a HUD bar +After a HUD bar has been added, you can change the current and maximum value on a per-player basis. +You use the function `hb.change_hudbar` for this. + +### `hb.change_hudbar(player, identifier, new_value, new_max_value)` +Changes the values of an initialized HUD bar for a certain player. `new_value` and `new_max_value` +can be `nil`; if one of them is `nil`, that means the value is unchanged. If both values +are `nil`, this function is a no-op. +This function also tries minimize the amount of calls to `hud_change` of the Minetest Lua API, and +therefore, network traffic. `hud_change` is only called if it is actually needed, i.e. when the +actual length of the bar or the displayed string changed, so you do not have to worry about it. + +#### Parameters +* `player`: `ObjectRef` of the player to which the HUD bar belongs to +* `identifier`: The identifier of the HUD bar type to change, as specified in `hb.register_hudbar`. +* `new_value`: The new current value of the HUD bar +* `new_max_value`: The new maximum value of the HUD bar + +#### Return value +Always `nil`. + + +## Hiding and unhiding a HUD bar +You can also hide custom HUD bars, meaning they will not be displayed for a certain player. You can still +use `hb.change_hudbar` on a hidden HUD bar, the new values will be correctly displayed after the HUD bar +has been unhidden. Both functions will only call `hud_change` if there has been an actual change to avoid +unneccessary traffic. + +Note that the hidden state of a HUD bar will *not* be saved by this mod on server shutdown, so you may need +to write your own routines for this or by setting the correct value for `start_hidden` when calling +`hb.init_hudbar`. + +### `hb.hide_hudbar(player, identifier)` +Hides the specified HUD bar from the screen of the specified player. + +#### Parameters +* `player`: `ObjectRef` of the player to which the HUD bar belongs to +* `identifier`: The identifier of the HUD bar type to hide, as specified in `hb.register_hudbar`. + +#### Return value +Always `nil`. + + +### `hb.unhide_hudbar(player, identifier)` +Makes a previously hidden HUD bar visible again to a player. + +#### Parameters +* `player`: `ObjectRef` of the player to which the HUD bar belongs to +* `identifier`: The identifier of the HUD bar type to unhide, as specified in `hb.register_hudbar`. + +#### Return value +Always `nil`. + + +## Reading HUD bar information +It is also possible to read information about an active HUD bar. + +### `hb.get_hudbar_state(player, identifier)` +Returns the current state of the active player's HUD bar. + +#### Parameters +* `player`: `ObjectRef` of the player to which the HUD bar belongs to +* `identifier`: The identifier of the HUD bar type to hide, as specified in `hb.register_hudbar`. + +#### Return value +A table which holds information on the current state of the HUD bar. Note the table is a deep +copy of the internal HUD bar state, it is *not* a reference; the information hold by the table is +only true for the moment you called this function. The fields of this table are: + +* `value`: Current value of HUD bar. +* `max`: Current maximum value of HUD bar. +* `hidden`: Boolean denoting whether the HUD bar is hidden. +* `barlength`: The length of the HUD bar in pixels. This field is meaningless if the HUD bar is currently hidden. +* `text`: The text shown on the HUD bar. This fiels is meaningless if the HUD bar is currently hidden. diff --git a/mods/hudbars/README.txt b/mods/hudbars/README.txt new file mode 100644 index 0000000..2fe7127 --- /dev/null +++ b/mods/hudbars/README.txt @@ -0,0 +1,109 @@ +Minetest mod: HUD bars +====================== +Version: 1.2.1 + +This software uses semantic versioning, as defined by version 2.0.0 of the SemVer +standard. + + +License of source code: WTFPL +----------------------------- +Author: Wuzzy (2015) +Forked from the “Better HUD” [hud] mod by BlockMen. + + +Using the mod: +-------------- +This mod changes the HUD of Minetest. It replaces the default health and breath symbols by horizontal colored bars with text showing +the number. + +Furthermore, it enables other mods to add their own custom bars to the HUD, this mod will place them accordingly. + +You can create a “hudbars.conf” file to customize the positions of the health and breath bars. Take a look at “hudbars.conf.example” +to get more infos. The lines starting with “--” are comments, remove the two dashes to activate a setting. Settings which are not +set will use a default value instead. + + +IMPORTANT: +Keep in mind if running a server with this mod, that the custom position should be displayed correctly on every screen size! + +Settings: +--------- +This mod can be configured by editing minetest.conf. Currently, the following setting is recognized: + +- hudbars_autohide_breath: A boolean setting, it can be either “true” or “false”. If set to “true”, + the breath bar will be automatically hidden shortly after the breathbar has been filled up. If set + to “false”, the breath bar will always be displayed. The default value is “true”. + +- hudbars_sorting: This setting allows you to specify the “slot” positions of the HUD bars manually. + + The setting has to be specified as a comma-seperated list of key=value pairs, where a key refers to the + identifier of a HUD bar and the value refers to the slot number of where the HUD bar should be placed. + The slot number must be an integer greater of equal to 0. The slot positions start (slot 0) at the + bottom (nearest to hotbar in default configuration) left side, the following slot 1 is at the right + side, slot `2` is on the right side again, but placed over the first HUD bar (slot 0), and it goes on, + in a zig-zag pattern. + All HUD bars to which no sorting rule has been applied will fill in all slots which have not been occupied + by the HUD bars specified in this setting, the slots will be filled in from the lowest slot number. + Note that the order of those remaining HUD bars is *not* fixed, it basically just boils down on which mod + “came” first. Don't worry, the mod will still work perfectly fine, this setting is entirely optional. + + Be careful not to use slot indices twice, or else different HUD bars will be drawn over each other! + + If this setting is not set, by default the health and breath bar are displayed at slot positions 0 and 1, + respectively (health bar at left bottom-most positoin, breath bar right from it). All other HUD bars are + placed automatically. + + Example value: + breath=0, health=1 + This places the breath bar at the left side, and the health bar to the right side. + +- hudbars_bar_type: Specifies the style of bars. You can select between the default progress-bar-like bars and the good old statbars + like you know from vanilla Minetest. Note that the classic and modern statbars are still a little bit experimental. + These values are possible: + - progress_bar: A horizontal progress-bar-like bar with a label, showing numerical value (current, maximum), and an icon. + These bars usually convey the most information. This is the default and recommended value.. + - statbar_classic: Classic statbar, like in vanilla Minetest. Made out of up to 20 half-symbols. Those bars represent the vague ratio between + the current value and the maximum value. 1 half-symbol stands for approximately 5% of the maximum value. + - statbar_modern: Like the classic statbar, but also supports background images, this kind of statbar may be considered to be more user-friendly + than the classic statbar. This bar type closely resembles the [hud] mod. + +- hudbars_vmargin: The vertical distance between two HUD bars in pixels (default: 24) +- hudbars_tick: The number of seconds between two updates of the HUD bars. Increase this number if you have a slow server (default: 0.1) + +Position settings: +With these settings you can configure the positions of the HUD bars. All settings must be specified as a number. +The pos settings are specified as a floating-point number between 0 to 1 each, the start_offset settings are +specified as whole numbers, they specify a number of pixels. +The left and right variants are used for the zig-zag mode. In the stack_up and stack_down modes, only the left variant is used for +the base position + +- hudbars_pos_left_x, hudbars_pos_left_y: Screen position (x and y) of the left HUD bar in zigzag mode. 0 is left-most/top, 1 is right-most/bottom. + Defaults: 0.5 (x) and 1 (y) +- hudbars_pos_right_x, hudbars_pos_right_y: Same as above, but for the right one. + Defaults: 0.5 and 1. +- hudbars_start_offset_left_x, hudbars_start_offset_left_y: Offset in pixels from the basic screen position specified in hudbars_pos_left_x/hudbars_pos_left_y. + Defaults: -175 and -86 +- hudbars_start_offset_right_x, hudbars_start_offset_right_y: Same as above, but for the right one. + Defaults: 15 and -86 + +API: +---- +The API is used to add your own custom HUD bars. +Documentation for the API of this mod can be found in API.md. + + +License of textures: +-------------------- +hudbars_icon_health.png - celeron55 (CC BY-SA 3.0), modified by BlockMen +hudbars_bgicon_health.png - celeron55 (CC BY-SA 3.0), modified by BlockMen +hudbars_icon_breath.png - kaeza (WTFPL), modified by BlockMen +hudbars_bar_health.png - Wuzzy (WTFPL) +hudbars_bar_breath.png - Wuzzy (WTFPL) +hudbars_bar_background.png - Wuzzy(WTFPL) + +This program is free software.

You can toggle this +by pressing j. + +SPRINT_SPEED (default 1.5) + +How fast the player will move when sprinting as opposed to normal +movement speed. 1.0 represents normal speed so 1.5 would mean that a +sprinting player would travel 50% faster than a walking player and +2.4 would mean that a sprinting player would travel 140% faster than +a walking player. + +SPRINT_JUMP (default 1.1) + +How high the player will jump when sprinting as opposed to normal +jump height. Same as SPRINT_SPEED, just controls jump height while +sprinting rather than speed. + +SPRINT_STAMINA (default 20) + +How long the player can sprint for in seconds. Each player has a +stamina variable assigned to them, it is initially set to +SPRINT_STAMINA and can go no higher. When the player is sprinting, +this variable ticks down once each second, and when it reaches 0, +the player stops sprinting. It ticks back up when the player isn't +sprinting and stops at SPRINT_STAMINA. Set this to a huge value if +you want unlimited sprinting. + +SPRINT_TIMEOUT (default 0.5) + +Only used if SPRINT_METHOD = 0. +How much time the player has after releasing w, to press w again and +start sprinting. Setting this too high will result in unwanted +sprinting and setting it too low will result in it being +difficult/impossible to sprint. diff --git a/mods/sprint/depends.txt b/mods/sprint/depends.txt new file mode 100644 index 0000000..3e1d5c2 --- /dev/null +++ b/mods/sprint/depends.txt @@ -0,0 +1 @@ +hudbars? diff --git a/mods/sprint/esprint.lua b/mods/sprint/esprint.lua new file mode 100644 index 0000000..7deeb6a --- /dev/null +++ b/mods/sprint/esprint.lua @@ -0,0 +1,125 @@ +--[[ +Sprint mod for Minetest by GunshipPenguin + +To the extent possible under law, the author(s) +have dedicated all copyright and related and neighboring rights +to this software to the public domain worldwide.
