I don't speedrun myself but I like to watch them, and people often use plugins that show on-screen enemy and character HP. I've tried finding these values in-game before using Cheat Engine out of curiousity, but couldn't find anything. But then I noticed that when enemies spawn, their values are instantly loaded. How does that work? How would the developer know how to find those values? Is there just a static piece of code with a fixed array of changing values that are pulled elsewhere?
