love.graphics.printf (简体中文)

绘制格式化过的文本，可折行显示、对齐。

参见 love.graphics.print.

The word wrap limit is applied before any scaling, rotation, and other coordinate transformations. Therefore the amount of text per line stays constant given the same wrap limit, even if the scale arguments change.

In version 0.9.2 and earlier, wrapping was implemented by breaking up words by spaces and putting them back together to make sure things fit nicely within the limit provided. However, due to the way this is done, extra spaces between words would end up missing when printed on the screen, and some lines could overflow past the provided wrap limit. In version 0.10.0 and newer this is no longer the case.

In versions prior to 11.0, color and byte component values were within the range of 0 to 255 instead of 0 to 1.

Aligning does not work as one might expect! It doesn't align to the x/y coordinates given, but in a rectangle, where the limit is the width.

Text may appear blurry if it's rendered at non-integer pixel locations.

示例

在屏幕上绘制一段文本，右对齐，宽度限制为125。

love.graphics.printf("This text is aligned right, and wraps when it gets too big.", 25, 25, 125, "right")

注意

注意limit参数会影响到居中对齐和右对齐时的显示效果。

love.graphics.printf("This text is aligned center",100, 100, 200,"center") -- center your text around x = 200/2 + 100 = 200
love.graphics.printf("This text is aligned right",100, 100, 200,"right") -- align right to x = 100 + 200 = 300

另：显示中文及中文换行的方法如下：

function love.load()
	--加载中文字体
	font = love.graphics.newFont("wqy-microhei.ttc", 18)
	love.graphics.setFont(font)
end

function love.draw()
	love.graphics.printf("我 是 一 个 地 球 人 我 是 一 个 中 国 人 我 是 一 个 地 球 人 我 是 一 个 中 国 人 我 是 一 个 地 球 人 我 是 一 个 中 国 人", 100, 200)--字间要手动加空格。应该有办法让空格显示弱化，叫leading还是什么的，待研究
