gamevar <varname> <value> <flags>

A gamevar is a game variable that can be used to store numerical data which can then be referenced between actors.

A gamevar's flags determine how it is referenced by the game. A gamevar with flags of 0 is known as a global variable. A global variable exists once in the code, and any time a global variable is set, the new value is seen by all actors. A gamevar with flags of 1 is a per-player variable. Per-player variables exist once per player in the game, with each player having their own copy of the variable. A gamevar with flags of 2 is a per-actor variable. A per-actor variable exists as many times in the code as there are sprites in the map. Each sprite has its own copy of a per-actor variable in memory.

A gamevar value has a range of -2147483648 (-231) to 2147483647 (231-1), also known as a signed 32-bit integer.
