Let's get programmy!

[Callid]

Hmm, I do wonder, is there a Java library that lets you do stuff similar to that?

Code: Select all

.txt-file:
task = You have been tasked by $taskGiver to $$taskDesc. $tgGender will reward you with $$reward.
taskDesc = $verb $number $object
reward = $=gold $/Simplified - of course, reward might not only be gold
gold = $number+gp $/Note the difference from "$number gp"!


Call:
String[] arg = {"task", "taskGiver=the Duke", "tgGender="+duke.getNominativePronoun(), "taskDesc.verb = kill",
		"taskDesc.object = the King", "task.reward.number = 1000"}; //Note that it's not task.reward.gold.number
System.out.println(UnknownLibrary.getLine(arg));

Output:
You have been tasked by the Duke to kill the King. He will reward you with 1000gp.

I doubt it, but I don't see why you would need a library for that, it seems fairly trivial if you just use string.Replace().

Only the top level would be all that easy. Interpretation of other stuff, like the $= operator or $++ would be a bit more complicated. In any case, as my friend was kind of like "Yeah, sounds interesting; you don't bother, I'll write that!", I'm not the one programming it anyway. I just wondered if something like this already existed, so he wouldn't have to write anything at all

If he wants, he can just put it in a class, and just call it whenever needed. :x

what would you need $++ for? I still feel like you're overcomplicating this for yourself, as you could basically just do something like (in pseudocode)

Code: Select all

define Map args;
args["task"]="You have been tasked by $taskGiver to $taskDesc. $tgGender will reward you with $reward."
args["taskDesc"]="$taskVerb $taskObject";
args["taskGiver"]="the Duke";
args["tgGender"]=duke.getNominativePronoun(); //which in this case we'll say resolves to "He"
args["verb"]="kill";
args["taskVerb"]="kill";
args["taskObject"]="the King";
args["reward"]=AsGp(amount); //which in this case we'll say is "1000 gp".

String output = "$task";
while(output.Contains('$')) //or however you want to smartly detect that you're done with replacing stuff
{
  for each key in args[]
    String replacer = "$" + key;
    output = output.Replace(replacer,args[key]);
}

makes a map from your variable names with their values, then replaces values in the string until there's nothing left to replace. So, each iteration of the loop would (roughly) go:

"$task"
"You have been tasked by $taskGiver to $taskDesc. $tgGender will reward you with $reward."
"You have been tasked by the Duke to $taskVerb $taskObject. He will reward you with 1000 gp."
"You have been tasked by the Duke to kill the King. He will reward you with 1000 gp."

$++ means the next character is erased. I left it out in my example above (for simplification), but it's necessary as otherwise the output, due to taskDesc.number being empty, would be:

Code: Select all

(...)tasked to kill  the King.(...)

I also planned for $+n, $-- and $-n (n being a whole number).
There is also $% to actually write a $

And it seems my friend has actually successfully written the program now, so

EDIT:

Code: Select all

welcome = Welcome to this little game of mine. Press 1 to start a new game, or write "load" in order to load a saved game.
version = Game version: {version}, database version: 0.1.0

//save
save.enterName = Please enter the filename of the savegame.
save.failed = Saving the game as "{filename}" failed. Please enter another filename, try again or write "q" to cancel.
save.success = Game "{filename}" successfully saved!

//load
load.enterName = Please enter the name of the file you want to load the game from.
load.notExistant = "{filename}" does not exist. Please try again or write "q" to cancel.
load.failed = "{filename}" could not be loaded. Please try again or write "q" to cancel.
load.castingError = An error occured while trying to load "{filename}". The file might be of an old version of the game, damaged or otherwise incompatible. Please enter another filename, try again or write "q" to cancel.
load.success = "{filename}" successfully loaded!

//minor errors
error.minor.invalidTime = An error seems to have occured, as the time of day has become invalid ({time}). The game will try to fix the issue by skipping ahead to the morning of the next day. Please report this error to the developers nonetheless.
error.minor.noGame = Neither has a saved game been loaded, not has a new one been started, so there is no game running yet!

//help
help.1 = Apart from whatever input is currently expected, the following commands are available at any time:
help.2 = i, info - displays information on the game and slave
help.3 = s, save - saves the current game to file
help.4 = l, load - loads a game from a file
help.5 = h, help - accesses the help
help.6 = version - displays the current vesion of the game
help.7 = quit - ends the program

(Also, I apparently can't spell "occurred" :x)

Okay..... So I have a question. I've scoured the internet to find a way to find where exactly the memory leak is happening, to no avail. I was wondering if any of you could help me find out why exactly an activity in android stays in memory (along with the bitmaps it's holding[this is where the largest chunk of memory is]) and doesn't release at least some of the memory upon leaving the screen into another activity. If I was programming in native Java for android I'm sure I'd have more of an insight but we are using Xamarin's Mono for Android libraries that wrap the android ones for use in C#.

$++ means the next character is erased. I left it out in my example above (for simplification), but it's necessary as otherwise the output, due to taskDesc.number being empty, would be:

Code: Select all

(...)tasked to kill  the King.(...)

then just run .Replace("  "," "); on the string until all instances of multiple spaces are gone as well, unless you're using extra spaces for formatting. And yeah, you could always include escape sequences to write $s, which I just left out to not have to write more, but either way I still think it's a relatively simple problem

and sorry kirby, don't have any android experience so I can't help ya much there. And is it an actual memory leak (in that mem usage goes up) or just that it's holding onto stuff longer than you want it to? I would think that android apps would have some way of knowing if they were the foreground or not, possibly you could free the data yourself when you no longer become the focus?

[Kirbypepe]

Well see the activities (Screens) all have a lifecycle and it's within the lifecycle where the programming logic happens. (i.e. OnCreate, OnStop, OnDestroy). The on destroy of the activity is getting called. however the resources don't seem to be released. I have used the Eclipse Memory Analyzer to check and it's still holding onto the resource. However calling the garbage collector more often seemed to make a difference, but not enough to say it's fixed. Since on the Galaxy S3 the app size can be 60MB we like hug that limit a lot.

[Akonyl]

have you actually run into any issues due to the memory not being immediately freed? Because garbage collectors aren't instantaneous, so it might just not be running until it needs to for performance. And is 60MB really that bad for a S3? I thought they had a lot more memory than that.

[Kirbypepe]

Well see when going from one screen to the next thats 37MB on it's own and that's just the home screen and the next screen in. Going 1 more screen puts us at 54-59MB....... that's because the GC's aren't releasing the memory instantaneous. If we try to go one more we crash. The GC doesn't collect. and well no but that's the limit we have 60MB. =\

*is totally happy to have succeeded in making his game (partially) mod(d?)able*

actions.txt: Actions and their properties
action.java: The action method (called when the action is executed); will be compiled at runtime
lines.txt: Which output the action is supposed to have (strictly speaking optional, but makes things much more clear)

congrats! same here. I just finished our special project, which I think isnt really special. (I found lots of source codes over the net -_-)

What did you do?
