Detailed Description

Configuration options of the network stuff.

It is used even when compiling without network support.

Definition in file config.h.

Variable Documentation

◆ NETWORK_MAX_GRF_COUNT

const uint NETWORK_MAX_GRF_COUNT = 62
static

Maximum number of GRFs that can be sent.

This limit is reached when PACKET_UDP_SERVER_RESPONSE reaches the maximum size of SEND_MTU bytes.

◆ NETWORK_NUM_LANDSCAPES

const uint NETWORK_NUM_LANDSCAPES = 4
static

The number of landscapes in OpenTTD.

This number must be equal to NUM_LANDSCAPE, but as this number is used within the network code and that the network code is shared with the masterserver/updater, it has to be declared in here too. In network.cpp there is a compile assertion to check that this NUM_LANDSCAPE is equal to NETWORK_NUM_LANDSCAPES.
