Solved interactions between two or more plugins which are in a single Python file

how can I make interactions between two or more plugins which are created in a single Python file, including the commandData plugin and the toolData plugin. now, I want to send a message from a toolData plugin to two or more commandData plugins if the 'if' conditions is Ture. but, I don't want to use global values in Python. How can I realize that. Thank guys!

@c4ds I had got a try.
I write codes:

commandPlugin=c4d.plugins.FindPllugin(the plugin id, c4d.PLUGINTYPE_ANY)
commandPlugin.Message(the integer)
 in GetCursorInfo() called back function of toolData.
and, codes:
if type== the integer:
   print(the integer)

in Message() called back function of commandData.
but the codes can't print "the integer" when I move the mouse with the toolData.
actually, I change codes like that:
print(the integer)
in Message() called back function of commandData. .
but I still can not receive a message.
I want to change a value or execute a function in the commandData baesd on the mouse movement of toolData or a message from toolData

You cannot simply call Message(the integer) on a CommandData.
As I mentioned in the link ( the CommandData expects a message of type MSG_COMMAND. You cannot pass any integer.

But since you want to send more information than just an integer you then cannot use the solution I provided by using the CommandData.ExecuteSubID.

Note that a CommandData is more like a "single-shot" action. It would probably be a better idea to look for something else to "change a value" than a CommandData.
Without knowing the whole idea behind your plugin it is hard to suggest something.

@c4ds Thanks! I had changed my solution. Thank you to reply me!

I had changed my solution.

If you could share the solution, or at least the concept behind it, this might help others with a similar problem looking for a solution.

I just use 'global value' to settle this problem. it is not good way or good solution for coding. but I have to solve this problem in a short time because it is just a little part of my plugin. I have so many problems to deal with that I can not waste my time.I think the message of commandData will update or call back when this command gui updates, or message maybe update with other conditions.sorry! I just a newbie for programming.
