REFramework Direct 2D

This is an REFramework plugin that adds a Direct2D scripting API.

Building

Currently suggest building in RelWithDebInfo so that when issues arise you can debug and fix them.

git clone https://github.com/cursey/reframework-d2d.git
cd reframework-d2d
cmake -B build
cmake --build build --config RelWithDebInfo

Example

local font = nil
local image = nil

d2d.register(function()
    font = d2d.Font.new("Tahoma", 50)
    image = d2d.Image.new("test.png") -- Loads <gamedir>/reframework/images/test.png
end,
function()
    d2d.text(font, "Hello World!", 0, 0, 0xFFFFFFFF)
    d2d.text(font, "你好世界！", 0, 50, 0xFFFF0000) -- chinese
    d2d.text(font, "こんにちは世界！", 0, 100, 0xFF00FF00) -- japanese
    d2d.text(font, "안녕하세요, 세계입니다!", 0, 150, 0xFF0000FF) -- korean
    d2d.text(font, "Привет мир!", 0, 200, 0xFFFF00FF) -- russian
    d2d.text(font, "😁💕😒😘🤣😂😊🤔🥴👈👉🤦‍♀️", 0, 250, 0xFFFFFF00) -- emoji

    local str = "This is only a test"
    local w, h = font:measure(str)

    d2d.fill_rect(500, 100, w, h, 0xFFFFFFFF)
    d2d.text(font, str, 500, 100, 0xFF000000)
    d2d.outline_rect(500, 100, w, h, 5, 0xFF00FFFF)

    local screen_w, screen_h = d2d.surface_size()
    local img_w, img_h = image:size()

    -- Draw image at the bottom right corner of the screen in its default size.
    d2d.image(image, screen_w - img_w, screen_h - img_h) 

    -- Draw image at the bottom left corner of the screen but scaled to 50x50.
    d2d.image(image, 0, screen_h - 50, 50, 50)
end)

API

d2d.register(init_fn, draw_fn)

Registers your script with d2d allowing you to create d2d resources and draw using them.

Params

• init_fn a function that gets called when your script should create d2d resources (such as fonts via d2d.create_font)
• draw_fn a function that gets called when your script should draw using d2d and the d2d resources you've created in your init_fn

d2d.create_font(name, size, [bold], [italic]) DEPRECATED

This function has been deprecated in favor of d2d.Font.new(...)

Creates a font resource.

Params

• name the font family name
• size the size of the created font
• bold an optional boolean value to make the font bold
• italic and optional boolean value to make the font italic

Notes

You must call this function from the init_fn passed to d2d.register. That's the only valid place to call it.

d2d.text(font, text, x, y, color)

Draws text on the screen at the position you supply using a font resource you've created.

Params

• font the font resource you've created in your init_fn via d2d.Font.new(...)
• text the text to draw
• x the horizontal position on the screen
• y the vertical position on the screen
• color the ARGB color of the text

d2d.measure_text(font, text) DEPRECATED

This function has been deprecated in favor of d2d.Font:measure(...)

Returns the width and height of the rendered text

Params

• font the font resource you've created in your init_fn via d2d.Font.new(...)
• text the text to measure

d2d.fill_rect(x, y, w, h, color)

Draws a filled in rectangle

Params

• x the horizontal position on the screen
• y the vertical position on the screen
• w the width of the rectangle
• h the height of the rectangle
• color the ARGB color of the rectangle

d2d.outline_rect(x, y, w, h, thickness, color)

Draws the outline of a rectangle

Params

• x the horizontal position on the screen
• y the vertical position on the screen
• w the width of the rectangle
• h the height of the rectangle
• thickness the thickness of the outline
• color the ARGB color of the rectangle

d2d.line(x1, y1, x2, y2, thickness, color)

Draws a line between two points

Params

• x1 the first horizontal position on the screen
• y1 the first vertical position on the screen
• x2 the second horizontal position on the screen
• y2 the second vertical position on the screen
• thickness the thickness of the line
• color the ARGB color of the rectangle

d2d.image(image, x, y, [w], [h])

Draws an image at the specified position, optionally scaled.

Params

• image the image resource loaded in your init_fn via d2d.Image.new(...)
• x the horizontal position on the screen
• y the vertical position on the screen
• w the optional width to scale the image by
• h the optional height to scale the image by

Notes

If the w and h parameters are omitted, the image will be drawn at its natural size.

d2d.surface_size()

Returns the width and height of the drawable surface. This is essentially the screen or window size of the game.

Type: d2d.Font

Represents a d2d font resource.

d2d.Font.new(name, size, [bold], [italic])

Creates a font resource.

Params

• name the font family name
• size the size of the created font
