If you want to watch the videos in order, download the up-to-date version of the road map from the pinned comment of the corresponding video: https://youtu.be/UEYMi9hZYP4 ------------------------------------------------------------------------------------------------------------------------------------- In this video, you will learn about the two modes of code execution order for CFC: Automatic (Auto Data Flow Mode) and Manual (Explicit Execution Order mode). In the automatic mode, the execution order follows the data flow and the topological location of the networks. While in manual mode, it is possible to modify the automatically assigned order and give priority to a specific block to be executed first, for example. The default one is the automatic mode, and you should keep using it unless you are sure what you are doing by altering the execution order!
