Available since LÖVE 0.9.0 |
This variant is not supported in earlier versions. |
函数
当用户输入文本时调用。例如,如果在键盘上按下 shift + 2,则会生成“@”。
概要
love.textinput( text )
参数
string text
- UTF-8 文本
Returns
无返回
注释
在 Android 和 iOS 上,默认禁用 textinput;调用love.keyboard.setTextInput来启用它。
例子
记录并打印用户输入的文本。
function love.load()
text = "Type away! -- "
end
function love.textinput(t)
text = text .. t
end
function love.draw()
love.graphics.printf(text, 0, 0, love.graphics.getWidth())
end
打印用户输入的文字,并在按下退格键(backspace)时删除一个文字。
local utf8 = require("utf8")
function love.load()
text = "Type away! -- "
-- enable key repeat so backspace can be held down to trigger love.keypressed multiple times.
love.keyboard.setKeyRepeat(true)
end
function love.textinput(t)
text = text .. t
end
function love.keypressed(key)
if key == "backspace" then
-- get the byte offset to the last UTF-8 character in the string.
local byteoffset = utf8.offset(text, -1)
if byteoffset then
-- remove the last UTF-8 character.
-- string.sub operates on bytes rather than UTF-8 characters, so we couldn't do string.sub(text, 1, -2).
text = string.sub(text, 1, byteoffset - 1)
end
end
end
function love.draw()
love.graphics.printf(text, 0, 0, love.graphics.getWidth())
end
