Need help with UDP connection:receive problem
Posted: Sat May 09, 2020 4:13 pm
I've been working on my multiplayer game and stuck on the moment when I decided to put packet reception of the client into 'main.lua', so i don't have to call it in every object that somehow interacts with the server. I have a stage called 'hub.lua' where the connection:receive was called only once (before I moved it) to approve the connection to the server. If approval was received, the stage changed to 'Stage.lua', where the game itself was supposed to be happening. In 'Stage' I have to update multiple items that require multiple connection:receive calls.
So here's what is happening:
If I run the code and the packet reception is only in 'hub.lua', then everything is working just fine, but if I add the packet reception code to the 'chat.lua' (which is first called in 'Stage.lua') for example, the game freezes with no crash reports. The same happens if I remove packet reception code from both 'chat' and 'hub' and place it in the 'main.lua', which lead me to a conclusion that the problem is caused by call of connection:receive.
The problem is definitely is not on the server side as I have checked all packets that are being sent to the client.
Here's the code:
"hub.lua" (somewhere in the 'hub.update' function) :
'main.lua' :
Any ideas on what might be wrong?
