Draw everything to a canvas, check the aspect ratio of the window

绘制到canvas上面

Draw everything to a canvas, check the aspect ratio of the window (local ratio = love.graphics.getWidth()/love.graphics.getHeight(); if ratio < 16/9 then) and calculate the offsett you need to draw the canvas to (offsetX = (love.graphics.getWidth() - love.graphics.getHeight()/9*16)/2; offsetY = 0) and do the same thing for Y (elseif ratio > 16/9 then offsetY = (love.graphics.getHeight() - love.graphics.getWidth()/16*9)/2; offsetX = 0 end). Then calculate the scaling for your canvas (local scale = ratio < 16/9 and love.graphics.getHeight()/(canvas_height) or love.graphics.getWidth()/(canvas_width); love.graphics.draw(canvas, offsetX, offsetY, 0, scale, scale)).
