How do I spawn an Actor from a string? That is, if someone were to put "Wombat" in a string, how would I make it spawn a Wombat from that string? Or if they put "Apple" it would spawn an Apple, etc.

Spawning an Actor from a string?
how can you get the String ?
How many option do user have to choose/put ?
Are those option object(s) or class(es) ?
You would have to programmatically change each String value to the appropriate class, and then create new instancees of the class from there.
See my response to your other discussion on converting a class to an actor.
1 2 3 4 | Class clss = null;if ("Wombat".equals(actorString)) clss = Wombat.class;if ("Apple".equals(actorString)) clss = Apple.class;// etc. |
I don't recommend using reflection for this. If you want a string to specify which actor to create, just create a different actor based on the string. To modify the above example:
1 2 3 4 | Actor actor = null;if ("Wombat".equals(actorString)) actor = new Wombat();if ("Apple".equals(actorString)) actor = new Apple();// etc |

Do you mean by casting? Because that wouldn't work.
What you would have to make a method that would allow user input, then have another method (or the same one depending on how you write it) that spawns an actor based off what the input was.
I would do something like this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | public void createActor(){ spawnFromString(askForInput());}public String askForInput(){ return //However you ask for input}public void spawnFromString(String str){ if (str.equals("Wombat")) spawnActor(new Wombat(), world); if (str.equals("Apple")) spawnActor(new Apple(), world); //etc.}public void spawnActor(Actor a, World w){ w.addObject(a, //x, //y);} |
