+# Day 1 - 17/02/21
+
+Ideaguyed the basics of the game's classes and mechanics, and implemented basic movement and setting of all the stats it will have. Here are the initial characters, synergies and stats I want to have:
+
+### Characters
+
+* Vagrant: shoots a projectile at any nearby enemy, medium range
+* Scout: throws a knife at any nearby enemy that chains, small range
+* Cleric: heals every unit when any one drops below 50% HP
+* Swordsman: deals damage in an area around the unit, small range
+* Archer: shoots an arrow at any nearby enemy in front of the unit, long range
+* Wizard: shoots a projectile at any nearby enemy and deals AoE damage on contact, small range
+
+### Synergies
+
+* Ranger: yellow, buff attack speed
+* Warrior: orange, buff attack damage
+* Healer: green, buff healing effectiveness
+* Mage: blue, debuff enemy defense
+* Cycler: purple, buff cycle speed
+
+### Stats
+
+* HP
+* Damage
+* Attack speed: stacks additively, starts at 1 and capped at minimum 0.125s or +300%
+* Defense: if defense >= 0 then dmg_m = 100/(100+defense) else dmg_m = 2-100/(100-defense)
+* Cycle speed: stacks additively, starts at 2 and capped at minimum 0.5s or +300%
+
+Perhaps I'm overengineering it already with the stats but I wanna see where this goes. From SHOOTRX it seems like figuring out stats earlier is better than later, and these seem like they have enough flexibility.

+
+-- There are two main things happening in the example above: first we're creating TextTags and then we're creating a text object that uses those tags.
+-- The way each tag works is fairly simple: a tag accepts 3 functions, init, update and draw, and each of those functions operates on the text's characters one at a time.
+-- In the example above, the text without tags is 'This text is yellow while this text is shaking and this text is normal'
+-- For each of the characters in that string, different functions will be applied based on what tags were previously applied to it.
+-- init, update and draw functions take in 3 arguments in common:
+-- c - the character in question, a table containing .x, .y, .r, .sx, .sy, .ox, .oy and .character attributes.
+-- i - the index of character in the string
+-- text - the reference to the text object
+-- The update function also takes in dt as the second argument.
+--
+-- After we're done creating TextTags, we have to create the actual text object.
+-- The way this is done is by specifying each line of the text object, along with its font, alignment, height multipliers and height offsets.
+-- The first argument (text_data) is a table of tables containing all relevant info:
+-- text - the actual string containing the text to be displayed, along with any tag information
+-- font - the font to be used for the text
+-- alignment (optional) - how the text should align itself, possible values are 'center', 'justified', 'right', if not specified then by default it's 'left'
+-- height_offset (optional) - how many pixels the line below this one should be offset by
+-- height_multiplier (optional) - multiplier over the font's height for placing the line below
+-- The text object itself also has .w and .h which corresponds to the width of the biggest line and height of all lines + offsets, respectively.
+-- If 'alignment_width' is set to a specific line then that line will be automatically set to that width, and if it is the biggest then .w will also be set to that value.

+LÖVE is an *awesome* framework you can use to make 2D games in Lua. It's free, open-source, and works on Windows, Mac OS X, Linux, Android, and iOS.
+
+[![Build Status: Windows](https://ci.appveyor.com/api/projects/status/u1a69u5o5ej1pus4?svg=true)](https://ci.appveyor.com/project/AlexSzpakowski/love)
+
+Documentation
+-------------
+
+We use our [wiki][wiki] for documentation.
+If you need further help, feel free to ask on our [forums][forums], our [Discord server][discord], or our IRC channel [#love on OFTC][irc].
+
+Compilation
+-----------
+
+### Windows
+Follow the instructions at the [megasource][megasource] repository page.
+
+### *nix
+Run `platform/unix/automagic` from the repository root, then run ./configure and make.
+
+	$ platform/unix/automagic
+	$ ./configure
+	$ make
+
+When using a source release, automagic has already been run, and the first step can be skipped.
+
+### macOS
+Download the required frameworks from [here][dependencies] and place them in `/Library/Frameworks/`.
+
+Then use the Xcode project found at `platform/xcode/love.xcodeproj` to build the `love-macosx` target.
+
+### iOS
+Download the `ios-libraries` zip file corresponding to the LÖVE version being used from [here][dependencies-ios],
+unzip it, and place the `include` and `libraries` subfolders into LÖVE's `platform/xcode/ios` folder.
+
+Then use the Xcode project found at `platform/xcode/love.xcodeproj` to build the `love-ios` target.
+
+See `readme-iOS.rtf` for more information.
+
+### Android
+Visit the [Android build repository][android-repository] for build instructions.
+
+Repository information
+----------------------
+
+We use the 'default' branch for development, and therefore it should not be considered stable.
+Also used is the 'minor' branch, which is used for features in the next minor version and it is
+not our development target (which would be the next revision - version numbers are formatted major.minor.revision.)
+
+We tag all our releases (since we started using mercurial), and have binary downloads available for them.
+
+Experimental changes are developed in the separate [love-experiments][love-experiments] repository.
+
+Contributing
+------------
+
+The best places to contribute are through the Bitbucket issue tracker and the official Discord server or IRC channel.
+For code contributions, pull requests and patches are welcome. Be sure to read the [source code style guide][codestyle].
+
+Builds
+------
+
+Releases are found in the 'downloads' section on bitbucket, are linked on [the site][site],
+and there's a ppa for ubuntu, [ppa:bartbes/love-stable][stableppa].
+
+There are also unstable/nightly builds:
+
+- Most can be found [here][builds].
+- For ubuntu linux they are in [ppa:bartbes/love-unstable][unstableppa]
+- For arch linux there's [love-hg][aur] in the AUR.
+
+Dependencies
+------------
+
+- SDL2
+- OpenGL 2.1+ / OpenGL ES 2+
+- OpenAL
+- Lua / LuaJIT / LLVM-lua
+- FreeType
+- ModPlug
+- mpg123
+- Vorbisfile

+-- Each node in it should have the following attributes defined:
+-- .x, .y, .neighbors or .links. Optionally: .rs, .color, .visited, .can_be_visited, .on_visit, .on_draw, .data
+-- An example would look like this:
+-- nodemap = {
+--  [1] = {x = x, y = y, visited = true, links = {2, 3, 4, 5}}
+--  [2] = {x = x, y = y - 64, links = {1}}

+--  [4] = {x = x, y = y + 64, links = {1}}
+--  [5] = {x = x - 64, y = y, links = {1}}
+-- }
+-- .data can be a table that contains other attributes. These will be automatically added to the Node object when it's created.
+-- .on_visit should be defined if you want the button to do something when it's clicked. Example:
+--  [2] = {x = x, y = y - 64, links = {1}, on_visit = function(visited_node) state.goto'level_2' end}
+-- .on_draw should be used when you want to draw the node in some specific way rather than the default one.
+-- color_mode can be nil or 'skill_tree', if it's the latter then nodes and edges will change colors according to if they were a part of a skill tree:
+-- Unvisitable nodes are gray, visitable nodes are white, visited nodes are their default color
+-- This is opposed to the default color mode, where all nodes and edges have their their default colors, and when they're visited they turn gray instead.
