| A gamevar is a game variable that can be used to store numerical data which can then be referenced between [[actor]]s.

|
| The syntax for defining a gamevar is 'gamevar <varname> <value> <flags>'
| | [[Category:Gamevar manipulation]] |
| | | [[Category:EDuke commands]] |
| 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 [[actor]]s. 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 [[sprite]]s in the map. Each [[sprite]] has its own copy of a per-[[actor]] variable in memory.

| In the next version of eduke32 it will be possible to use literal values and defined constants wherever a gamevar is required.
| |
| | |
| There are other flags but they can only be set when a gamevar is pre-defined by the game not when a gamevar is defined in con. Flags are powers of two to allow combination. The full list is given below.
