x1, y1, x2, y2, x3, y3, x4, y4 = Shape:getBoundingBox( )

Vertexes are returned starting from the bottom-left in a clockwise fashion (bottom-left, top-left, top-right, bottom-right).

Arguments

None.

Returns

number x1

The x-component of the first vertex, bottom-left.

number y1

The y-component of the first vertex, bottom-left.

number x2

The x-component of the second vertex, top-left.

number y2

The y-component of the second vertex, top-left.

number x3

The x-component of the third vertex, top-right.

number y3

The y-component of the third vertex, top-right.

number x4

The x-component of the fourth vertex, bottom-right.

number y4

The y-component of the fourth vertex, bottom-right.

Example

And here's the source code if you want to try/test/see it yourself.

function love.load()

    world = love.physics.newWorld(650, 650)
	    world:setGravity(0,700)
		world:setMeter(64)
		
	body = love.physics.newBody(world, 650/2, 650/2, 0, 0)
	shape = love.physics.newRectangleShape(body, 0, 0, 300, 300, 0)

		
	love.graphics.setFont(18)
    love.graphics.setBackgroundColor(255, 255, 255, 255)
	love.graphics.setMode(650, 650, false, true, 0)

end

function love.draw()

    X1, Y1, X2, Y2, X3, Y3, X4, Y4 = shape:getBoundingBox()
	
	love.graphics.setColor(0,0,0,255)
	
    love.graphics.print("X1, Y1", X1, Y1)
	love.graphics.print("X2, Y2", X2, Y2)
	love.graphics.print("X3, Y3", X3, Y3)
	love.graphics.print("X4, Y4", X4, Y4)

end
