quill's Introduction

quill

Quill is just a small wrapper based on pure UnityUI. You can create UI by using its c# api, programmatically.

Quill also comes with lua api support(experimental). That means you can run lua code from StreamingAssets and make ui in unity.

Components

Label

var label = Quill.CreateLabel("hello world");
label.element.SetSize(100, 30);
label.element.SetPosition(100, 100);

Button

var button = Quill.CreateButton("hello button!");
button.onClick.AddListener(SomeMethod);
button.interactable = false;

Box

var panelParent = Quill.CreateEmpty();
panelParent.SetSize(300, 80);

var box = Quill.CreateBox(Color.red);
var label = Quill.CreateLabel("Score: ");
label.alignment = TextAnchor.MiddleCenter;
label.fontSize = 32;

panelParent.Add(box);
panelParent.Add(label);

label.element.StretchToParentContainer();
box.element.StretchToParentContainer();

quill lua api

To enable lua feature, initialize and update the api like below. Quill will look into StreamingAssets/LUA directory for main.lua file.

private void Start()
{
    Quill.Init();
    QuillLua.Run(); 
}

private void Update()
{
    QuillLua.Update();
}

private void OnDestroy()
{
    QuillLua.Exit();
}

Here is the structure of the StreamingAssets/LUA/main.lua

function OnInit()

end

function OnUpdate(dt)

end

function OnExit()

end

Lua example

local timePassed = 0
local timeLabel = nil

function OnInit()

    local root = quill.empty()

    color = {}
    color.r = 0.4
    color.g = 0.8
    color.b = 0.3

    local box = quill.box()
    box:setColor(color.r, color.g, color.b)
    box:setSize(300, 100)
    root:addChild(box)

    timeLabel = quill.label("time")
    timeLabel:setSize(300, 100)
    
    root:addChild(timeLabel)
end

function OnUpdate(dt)
    timePassed = timePassed + dt
    timeLabel:setText("time: " .. string.format("%.2f", timePassed))

end
