share the link of game with my friends .
This is a very unclear question.
Could you confirm real quick that you mean generally sharing something from your game?
If so. That is certainly not possible via blueprint. You need to access those social media APIs and implement each different site separately. There is quite likely a C++ library somewhere helping with a few of those. But yea. You won’t have luck with blueprint.
ok how i do that in c++ ?
Yes. In that case my answer is accurate.
You don’t via Blueprint. You will need C++.
If you don’t find a library for it you’ll have to connect to the APIs various social media use and implement it to do what you want to. Usually this is done via rest APIs.
Here’s the link to facebooks API documentation for example.
