How can I transfer a collection of float values to a node socket​​?

Question

How can I transfer a collection of float values to a node socket​​?

This is what I've tried:

• Create a list of float values ​​and convert each of them to a string
• Pass the string to the socket
• In the right place in the script, I will retrieve the float values by accessing the string values from within an eval() function:

list_x = eval(self.inputs['Points'].VectorProperty.x)

list_y = eval(self.inputs['Points'].VectorProperty.y)

list_point = list(zip(list_x, list_y))

I understand that this is not correct. But what is the correct way to do this?

Answer 1

In the case you are describing you can use the NodeSocketVector a socket. It is a built in NodeSocket.

class MyNode(Node):
    def init(self):
        self.outputs.new('NodeSocketVector', name="Vector")

    def get_output_vector_value(self):
        return self.inputs[0].default_value
