+## Objects, Functions, and Variables in ISBPL
+OOP works like this:
+
+- There are three separate function resolvers:
+  - Object
+  - Local
+  - Global
+- They are executed in the order shown above
+- The object resolver peeks onto the stack, gets the type of the object, and checks for methods on the type, if it finds one, it executes it
+- The local resolver checks for functions defined in the current function, but not in any other function or area
+- The global resolver checks for top-level functions, meaning ones that arent in any other function.
+- Because variables are native functions under the hood, they are also called by the function resolvers
+- Object-local variables are in a Table: `Type?->Instance?->ID?->Value`
+
+### To call a method of an object:
+
+```isbpl
+parameter1 parameter2 etc object method
+```
+as explained above, methods are resolved separately, and it is therefore not required to define them in any other way.
