Your problem is that you never check if the mouse is released, so dactive is always true. Consider adding an else statement to the love.mouse.isdown check to set dactive to false.

I think the issue is a confusion about when to do what.

You need to capture the coordinate difference only when the mouse button goes down, not every frame while it's pressed. The easy way is to use the love.mousepressed event for that.

Code: Select all

function love.mousepressed(mx, my, b)
    if b == 1 then
        diffx = mx - x
        diffy = my - y
    end
end
Then, while the mouse button is pressed, you move the shape.

Code: Select all

function love.update(dt)
    if love.mouse.isDown(1) then
        mx, my = love.mouse.getPosition()
        x = mx - diffx
        y = my - diffy
    end
end
