Question: How do you display text in Love2D?

Answer

In Love2D, text can be displayed on the screen using the love.graphics.print function or by creating a Font object and then using it to print text. Here's how to use both methods:

Using love.graphics.print

This is the simpler method for drawing text directly on the screen. You specify the text, position, and optionally, rotation, scale, and other parameters.

function love.draw()
    love.graphics.print("Hello, Love2D!", 400, 300)
end

Using Font objects

For more control over the appearance of your text, you can create a Font object with a specific font and size, then use it to draw text.

function love.load()
    -- Load a font file at size 14
    myFont = love.graphics.newFont("font.ttf", 14)
end

function love.draw()
    -- Set the active font
    love.graphics.setFont(myFont)
    
    -- Print text using the selected font
    love.graphics.print("Hello, Love2D with custom font!", 400, 300)
end

To draw text with more advanced options like alignment and wrapping, you can use the love.graphics.printf function:

function love.draw()
    local text = "This text will be aligned and wrapped."
    local x, y = 100, 100
    local limit = 200 -- wrap the line after this many horizontal pixels
    local align = "center" -- can also be 'left', 'right', or 'justify'
    love.graphics.printf(text, x, y, limit, align)
end

When displaying text in Love2D, remember that the default font may not support all characters or look the way you want. In these cases, loading a custom font as shown above is the recommended approach.
