love.textinput

Available since LÖVE 0.9.0
This function is not supported in earlier versions.

Called when text has been entered by the user. For example if shift-2 is pressed on an American keyboard layout, the text "@" will be generated.

Function

Synopsis

love.textinput( text )

Arguments

string text
The UTF-8 encoded unicode text.

Returns

Nothing.

Notes

Although Lua strings can store UTF-8 encoded unicode text just fine, many functions in Lua's string library will not treat the text as you might expect. For example, #text (and string.len(text)) will give the number of bytes in the string, rather than the number of unicode characters. The Lua wiki and a presentation by one of Lua's creators give more in-depth explanations, with some tips.

The utf8 library can be used to handle UTF-8 encoded unicode text.

Examples

Record and print text the user writes.

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
