Hierarchical payment method

[noOob]

I want to create a payment method that uses multi payment methods in a hierarchical way. Usage example could be:

A client's cart price become $100, he has $50 score in site (AlphaUserPoint) and he could pay other $50 by credit cart or like that.

I need to write my own plugin (cause it's a little bit more complicated than this example) i need to know how to write a correct payment plugin for VM ( I searched for the document but there is none) and how shall i call other Payments?
directly or i think could change the $data and dispatch plgVmConfirmedOrder trigger or sth like that once again.

There are no docs but just use the bundled payment plugins as your examples

the "standard" is the simplest and then authorize is a good example of calls and passes to payment providors

Oh it takes time, thank you anyway.
