ok so I have a class called CustomMessage, this is a sprite that houses a text field, I have a box that is supposed to hold the CustomMessage sprite. The content that is generated for the CustomMessage is random in width and height. I find that whenever the height for the CustomMessage textfield is increased, the CustomMessage sprite moves higher up and sometimes off the screen. How can I get a fixed height so that the text to expand down and I can add whatever I want.
