Question

I’m completely burned out on this one, but why am I getting:

client.cpp: In member function 'void Client::netRead(int, int)':
client.cpp:158:57: error: no matching function for call to 'Client::nextGameUpdate(sf::Vector2i [0], int [0], sf::IpAddress [0], int&)'

Header

private:
sf::Vector2i pListVec[];
sf::IpAddress pListIP[];
int pListRot[];

I feel like it has something to do with the array I’m trying to fill with sf::Vector2i… /me stares blankly at screen

So very simply put. netRead gets info from another function that is very basic. Then the switch goes through the net_step int…

After the game has received all the packets needed to continue, we trigger the nextGameUpdate() and send it 3 arrays and a dataSize int variable.

Thanks in advance if you figure this one out. ^^

Answer 1

You are trying to pass pListVec into qq where the former is an array of Vector2i and the latter is a single Vector2i.

But there is also a bug in your logic. Substitute pListVec into qq in your update function, and the second statement reads:

pListVec[dataSize] = pListVec;

That cannot possibly be what you intended to do.

Also, since pListVec is a private field of your class, there is no need to pass it as an argument between member functions (at least in your case, where both methods are invoked on the same instance).
