Hello, thank you for your help and explanation. My exploration of Path is still limited to drawing a map and displaying the path from the starting point to the end point based on the clicked position. I'm still far away from using followers. Because my native language is not English, the text content in the tutorial is difficult for me to understand. So I adopted the simplest and crudest method, which is to copy each widget in the tutorial after installing the Path component on the local decker, and then change the values to explore the principle myself. However, when I applied the code to the map I drew myself, it failed. This is what troubled me in the first step.
I apologize for replying to you so late. For some time, I found that my Itch official website was unreachable and I couldn't log in to my account. Since then, I have been searching for a solution until just now when I finally logged in and rushed to reply to you. During this period, I used a clumsy method to figure out how to use Path. As for the method of "how to make a character move to a certain location to trigger an event", I am currently trying it out based on your suggestions. Thank you very much for your help
