Panel_lib docs

1. Panel structure

A panel is a custom object made of 2 HUD elements, the title and the background, plus a group of two sub-elements: the text and the images. Picture the background as the container of all the things you want to showcase in your HUD. Those things go in the sub-elements.

1.1. Declaration

To declare a new panel, simply do
local panel = Panel:new({parameters})

The parameters it takes are the following:

player: the player to assign the panel to
position: the panel position (as in any other HUD)
alignment: same
bg: the picture to put in the background
bg_scale: its scaling
title: the default text
title_alignment
title_offset
title_color
sub_img_elems: (table) whatever image to add to the panel
sub_txt_elems: (table) whatever text to add to the panel

1.2. Sub-elements

Sub-elements are HUDs added on top of the main container, sharing the same position. This means two things:

As a HUD, they take the same parameters a HUD takes. They are clones respectively of the background and the title, so if you skip some parameter, they'll keep their reference default value.
If you wanna move them around, you must tweak the offset, NOT the position. If you change the position, they may look fine in a screen resolution, but not in another. In order to prevent it, panel_lib automatically overrides the position with the panel's.

Have a look at the example file to see a complete panel declaration.

2. Configuration

Install it as any other mod ¯\_(ツ)_/¯

2.1. Functions

new({params}): creates a new panel
show(): makes the panel appear
hide(): makes the panel disappear (but it's still assigned to the player)
remove(): deletes it
update(panel_params, txt_elems, img_elems): updates only the mentioned parameters. For instance, calling

panel:update(nil, nil, {my_custom_img = {
      text = "pic2.png"
    })

updates just the text of the sub-element my_custom_img.

There is also a getter, to obtain the panel associated with a player

panel_lib.get_panel(player_name)

3. Collaborating

Something's wrong? Feel free to open an issue, go for a merge request and whatnot. I'd really appreciate it :)
