Why does this collision code not work? (love2d)

Question

function love.collide ()
  if x < 0 then
    x = 0
  end

  if x < love.graphics.getWidth () - Dolphin:getWidth () then
  x = love.graphics.getWidth () - Dolphin:getWidth ()
  end

end

I'm trying to make an x coordinate collision and I have already defined x previously. There is no error but the collision fails to work.

I think you mean x > love.graphic.getWidth() - Dolphin:getWidth(). Because otherwise your Dolphin should always be stuck at the right-hand boundary.

I assume that you want to detect the collision between your object (Dolphin) and the boundary of the screen, but you are not comparing the position of the object (which changes); instead you compare the width of the object, which probably doesn't change.

When I use getWidth, I'm getting the width of my window size not the width of the object. However, I did get this to work simply by changing it to function love.update
