Hopefully I'm interpreting this right, it sounds like there are 14 different selectable characters in the game, and you have a generalized character rig setup that has a spot for the selected character in the middle, and then 4 boxes situated around the character, representing attack zones to the left, right, top, and bottom of the character.
You want a control input, like Towards + C, to trigger a unique action depending on the chosen character.
Two options come to mind, global variables is one, and a callback function system is the other. The global variable method is easier but a little less flexible, though it should still work just fine in this case.
You can use a global variable to store the name of the character chosen by the player, and only trigger that character's attack if their name is found in the global.
* Event: If keyboard pressed Left + C.
* * SubEvent: If global characterName = "lulu". -- Action: Call function "luluShield".
* * SubEvent: If global characterName = "veigar". -- Action: Call function "veigarStun".
* * SubEvent: If global characterName = "teemo". -- Action: Call function "teemoSelfDestruct".
You can create a Dictionary object, that maps control input events (Dictionary keys) to function names (Dictionary values). At the point that a player selects a character, you can populate the Dictionary with the chosen character's functions. These functions will execute the character's actions.
* Event: Player chooses "lulu".
Add to Dictionary key = "Left+C", value = "luluShield" .
Add to Dictionary key = "Right+C", value = "luluSpeedUp".
* Event: If keyboard pressed Left + C. -- Action: Call function ( Dictionary.getValue( "Left+C" ) ).
Note: Dictionary.getValue( "Left+C" ) will return "luluShield", which we added earlier, and so the action evaluates to [Call function ( "luluShield" ).]
* Event: On function "luluShield". -- Action: Execute the stuff that's supposed to happen when Lulu uses her shield ability.
Hope that helps.
