Hey All,
So i have set up NSUserDefaults in a GameConfigs file and it works perfectly but my question is. is there a way to load the stats kind of like this:

player1Sprite.speed = [[SnowFightConfigs get] [NSString stringWithFormat:@"%@Speed.png", play1name]];

So what i want to do is get the property *playername*speed where playername is a string that i set earlier when they chose a character.

so if the NSString play1name is john i would want it to get this:

player1Sprite.speed = [[SnowFightConfigs get] johnSpeed];

How could i do this? I asked on iPhonedevsdk but no one ever answers there. So im asking here
Thanks

I don't see the point in doing this. If you want to have "dynamic ivars", why not store them in an NSDictionary or NSMutableDictionary ?

Hey,
I havent looked into dictionaries really. Pretty much what I have is a total of about 8-12 selectable characters, but only 3 can be chosen at a time. So right now i have it set up that when they select a character it adds that name to an array. then when they hit play it takes the names in the array and puts it into three strings. play1name, play2name and play3name.and i want the attributes to only load for the character they selected.

oh and that first line of code shouldnt have .png on it.

Could i accomplish this with NSDictionary?
Thanks

You can do it various ways. Instead of adding the character's name to an array when it is selected, you could add an int (index) representing the character to the array. Then, when you load your attributes, you could simply get them from another array based on the indexes of the selected characters.

You could also do it with an NSDictionary as I suggested earlier. It's like using NSUserDefaults. You get a value for a specific key. The keys could be "johnSpeed", "johnAcceleration", "mikeSpeed", etc. It's really close to what you intended to do. Plus, you could store your characters attributes in a .plist file and access them through an NSDictionary instance.

Hey,
Im doing it the same method that Gorrillas is using which is a NSDictionary. Like i said im very new to NSDictionary. are there any good tutorials that would help me with that?
Thanks

Try something like this:

NSString *s = [NSString stringWithFormat:@"%@Speed.png", play1name];
Class *c = NSClassFromString(s);
player1Sprite.speed = [[SnowFightConfigs get] c];

NSUserDefaults
