Yes. It is possible to import multiple .py files (your classes) from within your plugins folder.
Here's the jist of it:
-Create a .py file with your class in it.
For this simple example. The external class will be called "MyClass"
-Make your class code look like this:
class MyClass() :
def __init__(self, name = 'Scott') : #The constructor with a required name parameter
self.name = name #Sets up the name parameter to work
-Name the .py file "MyClass.py"
-Put the file in your plugins folder
-At the top of your plugin code. Add these three lines of code:
import.os
sys.path.append("C:/Program Files/MAXON/your CINEMA 4D version/plugins/MyPlugin")
from MyClass import MyClass
*Note: Make sure you edit that code to your specific path names!!!!
-Next. In your plugin code. You'll need to instantiate your external class like this:
class Sub(MyClass) : #The parent class this class is connected to is listed in the parentheses
def __init__(self) : #The sub class's constructor
MyClass.__init__(self) #Call to the super class called "MyClass" in the external file
-Now you can call to that external class from withing any of your plugin's methods.
Example:
def Execute(self, tag, doc, op, bt, priority, flags) :
s = Sub() #Create an instance of the sub class..Which is also inheriting things from the external MyClass.py file
print s.name #Prints the default name parameter value that exists inside of the MyClass.py file
return c4d.EXECUTIONRESULT_OK
FYI:
Be aware that you'll sometimes have to shut down C4D and restart it when adding your external stuff.
Using: print sys.path will let you know whether or not the folder you're targeting is actually set up as a valid path.
I've only done this a couple of times. And I haven't really tested it that much yet. So no guarantees that it's bug free.
But so far it seems to work fine for me.
