## Usage
29
30
-
You can, of course, just use this as a usual Lua program. The code assumes you load the class file, call it, and assign the resulting function returned to a global variable `class`. You can then load the `hooks` file, along with any other libraries you'd like (i.e. the different systems). Due to the nature of this framework, I will not be writing code to load a system's code, but it shouldn't be too difficult to do so.
31
-
32
-
After loading everything, call the following code:
33
-
34
-
```lua
35
-
Hooks:emit("init")
36
-
```
37
-
38
-
This will call every function callback under the `init` event.
