Hi. I have a basic scenario with an actor that i can move using keyboard input. It just adds or substracts a number of pixels to its coordinates. This number is stored in a variable. What I want is to have a text box in the same scene which controls that variable, so I can change the speed the actor is moving by changing the text in the text box. How can I do something like that? Thanks in advance.

You probably need to create a subclass of Actor for the object; create the base image in the constructor; add a field for the text; create a method that create an image of the text, draws it on the base image and sets it to the actor; add a boolean field to represent focus state; add code to the act method to check for focus, and if focused, check keyboard input and adjust the text and update the image as needed.
