It might sound weird.Assume that i have a simple software which named A with just a button. And i had a custom event in my Level BP.How do i trigger that custom event in Level BP by clicking A’s button? Thanks in advance everyone!
You have a few different options. You could add a tcp/ip listen server to UE4 in C++ and then have “software A” call that listen server and then raise the event to your blueprint. That is probably the best solution, but will likely take a bit of work. If you don’t want to write a lot of C++ in UE4, then you could use the VaREST plugin to poll a service that runs in “software A”. This is what I do and it is quote simple. If you write “software A” in C# .NET you could build an app to do what you want in just a dozen lines of code.
The answer is very helpful! You are awesome! Thank you so much! Love u
