I have seen the instructional video on how to create a custom flow chart block, (https://www.youtube.com/watch?v=UBwJtqUdhgM&list=PLUJJN9tmVTj1czFMt9IKi6wge9GnmMTN3&index=8) and it is similar to what I want to do. I need to repeat this same flow for 3 different types of agents. In the video, he creates a parameter called seizedResource that he references in the Seize block. He can then select which resource pool to use for that custom flow chart block in the main environment. I would like to do the same thing, but instead of selecting a resource pool for my custom block I would like to select an agent type. How would I do this?
