Hey Eskimo ! Thank you for this quick answer. I will check everything you sent me Tommorow. Just a question, you told me about Quic , is this the best choice if I want something very smooth ? I prefer going for something more complexe and better for the user than something easier for me even if it has to take some time to understand. Also you said that UDP exposes me to the above limitations, are you talking about the package size,…?and thank you again for taking your time to help me :)
