Hi, I'm struggling with removing an event in my drag & drop code.. that.pants.once('mousedown', function(mouseData) { that.pants.on('mousemove', function(mouseData) { that.pants.position.x += mouseData.data.originalEvent.movementX; that.pants.position.y += mouseData.data.originalEvent.movementY; that.pants.once('mouseup', function(mouseData) { console.log("how do I remove mouse move event?!") }); }); });I have tried using callbacks but to no success.. If someone knows what would the syntax look like for the prototypal pseudo-classical pattern I am using. Thank you!
