In this article we outline the development of the QField with Scratch. We start by drawing the playing field and implementing the random movement of Scratch. In the next step, we introduce the Q table, which serves as the basis for reinforcing learning. Finally, we visualize Scratch's decisions through drawn arrows that represent his path on the playing field.<\/p>\n\n\n\n\n\n\n\n
To draw the playing field for the QField, you can either use a pre-made card or create the playing field yourself. To do this, you need three objects: the cat Scratch, the object \"cake\" for the target field and another object, ideally the \"Pencil\", which is used for drawing and remains hidden.<\/p>\n\n\n\n\n\n
