Available since LÖVE 0.8.0
This function is not supported in earlier versions.

Shears the coordinate system.

O.png In version 0.9.2, a bug caused this function to reset all transformations. It was fixed in 0.10.0. A workaround for 0.9.2 would be to use a combination of rotating and scaling to imitate shearing.  


Function

Synopsis

love.graphics.shear( kx, ky )

Arguments

number kx
The shear factor on the x-axis.
number ky
The shear factor on the y-axis.

Returns

Nothing.

Examples

Squish a rectangle

function love.draw()
	love.graphics.translate(100, 100)
	local t = love.timer.getTime()
	love.graphics.shear(math.cos(t), math.cos(t * 1.3))
	love.graphics.rectangle('fill', 0, 0, 100, 50)
end
