Question: How do you draw in Love2D?

Answer

In Love2D, drawing is done within the love.draw() callback function. Here is a basic example of how to draw shapes, text, and images:

function love.load()
    -- Load an image file into memory
    myImage = love.graphics.newImage("path/to/image.png")
    
    -- Define a font and its size
    myFont = love.graphics.newFont("path/to/font.ttf", 16)
end

function love.draw()
    -- Set the color for drawing (R, G, B, A)
    love.graphics.setColor(1, 1, 1, 1) -- White color
    
    -- Draw a rectangle: mode ("fill" or "line"), x position, y position, width, height
    love.graphics.rectangle("fill", 100, 100, 200, 150)
    
    -- Draw a circle: mode ("fill" or "line"), x center, y center, radius
    love.graphics.circle("fill", 300, 300, 40)
    
    -- Set the color to red
    love.graphics.setColor(1, 0, 0, 1) -- Red color
    
    -- Set the current font
    love.graphics.setFont(myFont)
    
    -- Draw some text: string, x position, y position
    love.graphics.print("Hello, Love2D!", 400, 200)

    -- Reset color to white before drawing the image
    love.graphics.setColor(1, 1, 1, 1) -- White color
    
    -- Draw an image at the specified position
    love.graphics.draw(myImage, 500, 50)
end

Each call to a drawing function should be made inside the love.draw() function or another drawing-related callback. When the window is created, Love2D will begin running in a loop where love.draw() is called every frame.

Love2D offers various other drawing functions and capabilities such as rotating, scaling, different blend modes, canvases for off-screen rendering, shaders, and more. These features allow for more advanced visual effects and control over the rendering process.

Remember to always check the Love2D documentation for the most up-to-date information on available drawing functions and parameters.
