How do I create a yml file and read it

I want to create a file that when executing a command it stores (world, locx, locy, locz) of a block that I am looking at.
I already got all the location of the target block, but wanted it when executing the command.
I would check if the file exists, if it does not exist then create: Ok
Save your data as follows:



I want every time I run the command it increments one more number in the sequence and adds below it (location, clear-inventary, chestpack).

I

The biggest problem I have and the number in quotes.
Because I do not know how I create it or how I add +1 to each executed command.
It's also a way of reading.
When I run another command it checks in the .yml file if it has inside the chestpack: default2 and capture the (location, clear-inventory) only of the session that I have chestpack: default2.

 

Each of the numbers underneath "chests" will be part of a path. All of it will begin with chests.
http://wiki.bukkit.org/Configuration_API_Reference is helpful, it's worth it to experiment.

 

I understand, but how do I create this ('0', '1')?

Example:
When I execute a command it saves in the file the chest in the section chests but always with that number in parentheses before.

 

Code:

int maxChestNum = 0;
for(String s : getConfig().getConfigurationSection("chests").getKeys(false)) {//Gather up everything that's once indented underneath "chests"
  //s will be all of the chest numbers, because they're once indented (not twice, not negative once)
  try {
    int i = Integer.parseInt(s);
    if(i > maxChestNum) maxChestNum = i; //We're basically scanning and counting up to see which max number we reach so we can find our next number.
  }
  catch (Exception e) {
    continue; //Whatever we got was not a number or Int, guess we must ignore it
  }
}
getConfig().set("chests."+String.valueOf((maxChestNum+1)), "loc,etc,4 or so times"); //The path for your next chest, i.e. number that isn't taken yet

 

The code is failing, where am I wrong?
There is no error in the code plus the command fails to run.

 

@aionchaos
What is not working? Does the path get saved to the config? are the values for the WXYZ correct?

BTW: @Drkmaster83 , you set it up so it always will override the path with the highest number. t will always be equal to an existing path, so it will always override one of them. For both of you, to fix this issue, add "t++;" at the end of the for loop (right before you create 'w')

 

1. The value of t will change as your progress through your loop, so even if the chests turned out to be out of order
('0', '4', '1', '2', '3'), your system would still think 4 (even though it's already made) is the next number (since 3 > 0 and it's the last number the loop sees).
2. Your original posted yaml syntax said the base key was "chests", not "Chests"
3. You will never be able to save a chest if someone puts one of the chests as "Potato" or the like instead of '(a number here)'

@Zombie_Striker In my original code, I got the highest number, and then

Edit: One thing I wasn't thinking about at the time I wrote that code is the path after the next number, i.e. the location, items, etc
@aionchaos https://www.diffchecker.com/4JQajYZd (pretty sure this is functional)

 

I corrected that mistake. My mistake!
More remains with the failure to execute the command.

 

@aionchaos
Something is null on line 75. Is that line 75?

 

Pretty sure that code literally does nothing different than what it had on your previous post. Also,

@aionchaos https://www.diffchecker.com/b401k287 <-- Even more functional (excuse the added code for functionality, changes are reflected in right-hand code's comments)
The null would be the if statement if we hadn't created our first chest yet.
Also, @aionchaos, a word to the wise would be to check if the chest already exists in the config

 

I've been trying since early today, so I changed the name to Chests.
I made the changes.
I added some information to the PNG field of view.


Sorry it took me a long time to respond and because my internet has dropped more than 10 times.

Code worked like this.
I just added line 77 (ch.createSection ("Chests")
Then he saves the first chest.
Then I noticed a problem.
When I try to save the second chest, save on top of the first one.
That is, it replaces the first.
I do not understand, line 80-83 should solve this.
The variables are at the beginning of the class.

 

There's a reason in my code I had an if statement before the createSecion statement. Everytime you create it, it erases everything underneath it and starts from scratch.
Change

Code:

ch.createSection("Chests");

to

Code:

if(ch.getConfigurationSection("Chests") == null) ch.createSection("Chests");

 

Worked perfectly.
Thank you @Drkmaster83
Now I just have to make a way to check if the chest already exists or not because it's added chest repeated.
Do you have any idea to do a type check?

 

Just check the location in your count up loop, you have the data there anyway, might as well use it

 

I have a plugin that does something similar to what you are talking about @aionchaos Would you like to see the snippet that may work for you?
