165793Function from string?
- Nov 5, 2013I'm writing a game. Well, actually I guess it's more of a game engine. I
want the game logic to be in a script. The script will take the form of
a series of rooms, each of which can contain:
. doors to other rooms
. characters the player can interact with
. things the player can pick up and use
Any of these can have conditions on them. The condition can be expressed as:
. Player must have (thing) in his inventory
. Player must have at least X points
. Player must have at least $Y money
. Call function "f"
That last seems to be a problem. I would like to be able to take a
function name I've read from the script and call the corresponding
function. Or, alternatively, the script can contain the name of a class
which must contain a method named (for example) conditionTest.
But I haven't figured out a way to convert a string to either a Function
or a Class. Is there a way of doing this? If I were working in
Can I do this? Or do I have to put all the functions I might want to
call this way in an array, and look them up that way? Or what?
