-Hey guys, few days ago I discovered I could load objects created in scripts at runtime, and cast them to an interface to call their methods provided
-1. both host program and script have access to the same interface via a common library
-2. script object implements that interface
-
-I was thinking, maybe I could implement appstates in scripts to implement game mechanics and attach them to the state manager at runtime, and similarly for components of an ECS. What do you guys think?
