Help in communication with external environement

[anes47]

Hi,

I have a question regarding the logic procedure.

I want to control a 3D simulator witch is developing in Unity game engine from WinCC OA.

Kind of pushbuttons in Wincc OA panel that control the movement of an object in Unity (How to send signals to extern environement)

Thank you

You have to look which protocols the external application supports. Probably you will then find out how to communicate with WinCC OA.

Probably I do not understand the answer.
What is "communication via JSON file"?
What does "listen to JSON file" mean in detail?

Is it meant that some writes the JSON file and the application reads it then (by a trigger)?

I have a 3d simulator in Unity and I need to control it from WinCC OA (Because I found difficulties to integrate it directly to WinCC OA as an EWO), So I want to create for example a "PushButton" in WinCC and when I click to this last one it will send a message to Unity via JSON to do something, it is possible ?


thank you a lot

JSON is not a protocol, it is just a type of formatting data.
Which protocols does the 3rd party application support?

Unity can use TCP socket connection as protocol

If the 3rd party application has TCP server socket you can use the tcp* CTRL functions to send data to this socket.
