Project description

Dota 2 Counter Picker 0.9.0 version

This the utility for choosing the best combinations of heroes and counter picks.

A current development state is available in the CHANGELOG.md file.

Installation

You need two Python 3, Tkinter and Pillow modules to launch the Dota 2 Counter Picker.

Windows

These are steps to install dota2picker on Windows:

  1. Download the Python 3 distribution:
    https://www.python.org/downloads/release/python-373/

  2. Install Python 3.

  3. Install Dota 2 Counter Picker:
    python -m pip install --user dota2picker

This is an alternative way to install dota2picker from github repository:

  1. Install the pillow module:
    python -m pip install pillow

  2. Install the setuptools module:
    python -m pip install setuptools

  3. Download the archive with the dota2picker and extract it:
    https://github.com/ellysh/dota2-counter-picker/archive/master.zip

  4. Change directory to the dota2-counter-picker and launch the command:

Dota2picker will be installed to the ~/.local/bin directory.

Usage

Picker

The d2-picker.py script shows you which heroes are bad or good against the chosen one. Also, the script shows which heroes can be combined well.

Picker Script

Start the d2-picker.py script and click on the hero icon. The yellow color will highlight it. The red color highlights all heroes who can easily beat the selected one. We can say that the selected hero is "bad against" them. The green color means that the chosen hero is "good against" the selected ones. The blue color shows heroes which can be combined effectively with the selected hero in one team. It means that he "works well with" them.

The script allows you to pick several heroes at the same time. Then it shows relations of all picked heroes.

There are three digits under each hero icon which estimate him. These are meaning of these digits:

  1. How many of the picked heroes (they are highlighted yellow) are bad against the hero on the corresponding icon?
  2. How many of the picked heroes are good against this one?
  3. How many of the picked heroes are works well with this one?

Let's consider an example with the window on the screenshot above. The enemy team has picked two heroes: Mars and Monkey King. Both of them are bad against Batrider. Thus, Batrider gets scores "2 0 0". If you pick Batrider for your team, it will be a good choice in this case.

At the same time, Monkey King is bad against Spectre but Mars is good against her. Thus, Spectre gets scores "1 1 0". She is still highlighted red because her bad and good scores are equal. She will get the green color in case of "1 2 0" scores for example. If you pick Spectre against Mars and Monkey King, probably you will have a tough game.

There are three buttons with red, green and blue color at the bottom of the window. You can press each button and filter the highlighted heroes. If you press the red button, only heroes which are strong against the chosen one will be highlighted. The green and blue buttons work the same for "good against..." and "works well with..." heroes.

You can cancel the current selection of heroes by the Esc button.

Editor

The initial version of the database with heroes was prepared based on the Dota 2 Wiki. The d2-editor.py script allows you to edit this database.

Editor Script

Start the d2-editor.py script. It looks like the d2-picker.py script. Meaning of all colors is the same.

These are steps to remove the hero from the "bad against..." relations:

  1. Choose the Lifestealer hero for example. The yellow color will highlight him.

  2. Press the red button at the bottom of the window. You will see only heroes with "bad against..." relations for Lifestealer. Now you are in the editing mode.

  3. Press the Monkey King hero. You will see that the color of his button becomes grey. This hero was removed from the "bad against..." relations for Lifestealer.

  4. Finish the editing mode by pressing the red button again. Now you see all three relations of Lifestealer. Monkey King hero is not counter pick for Lifestealer anymore.

You can follow the same algorithm for adding a hero to relations. Also, you should follow the same steps for adding/removing a hero to the "good against..." and "works well with..." relations.

The d2-picker.py, d2-checker.py and d2-editor.py scripts use the same database. It means that you will see all your changes in all these scripts.

This is path to database with heroes on Linux:
~/.local/share/dota2picker/Database.pkl

This is path to database with heroes on Windows:
C:\User\<username>\AppData\Local\dota2picker\Database.pkl

Checker

After editing the database, you want to check if it is consistent. The possible issue is you specify a hero A as "bad against..." the hero B but you forget to specify vice versa relation. This relation means that the hero B should be "good against..." the hero A. The d2-checker.py script checks for such kind of mistakes in the database. If you launch the script in the console (or Command Prompt on Windows), you see the report about such mistakes.

This is an example output of the script:

Tiny is "good against" Naga Siren but Naga Siren is not "bad against" Tiny

By default, the script does not fix these issues but it has two option to do it:

  1. Use the -a command line option to add missing heroes to the required list:
checker.py -a

Let's see on our example output above. After the command with -a, Tiny will be added to the Naga Siren's "bad against" list.

  1. Use the -d command line option to remove extra heroes from the required list:
checker.py -d

After the command with -d, Naga Siren will be removed from the Tiny's "good against" list.

Another possible issue is conflicting relations. Let's assume that hero A is good against hero B according to the database. At the same time, the hero B is good again A by accidental mistake.

This is a possible output of these mistakes:

Naga Siren has Huskar in both "bad against" and "good against" lists
Huskar has Naga Siren in both "bad against" and "good against" lists

It means that Naga Siren and Huskar has conflicting relations and counters each other. You should fix it by the d2-editor.py script in three steps:

  1. Remove Naga Siren from the "good against..." list of Huskar.

  2. Remove Huskar from the "bad against..." list of Naga Siren.

  3. Launch the d2-checker.py script again.

Now the report about conflicts should be empty.

The d2-checker.py script works with the database in the Pickle format (the Database.pkl file).

Import and Export

The d2-picker.py, d2-checker.py and d2-editor.py scripts use the database in the Pickle format (the Database.pkl file). This is a binary format, which is not convenient for reviewing in a text editor and comparing with other database files.

The d2-pkl2csv.py script allows you to convert the database from the Pickle format to the CSV. If you launch the script, you get the Database.csv file in the database directory (see the "Editor" section). You can open this file in any text editor or MS/Libre Office application.

When you are done with reviewing the database in the CSV format, you should launch the d2-csv2pkl.py script. It converts the database back to the Pickle format and stores it in the Database.pkl file.

Update

You can update Dota 2 Counter Picker with the pip package manager or from github repository (see the "Installation" section). Your database files stay unchanged after the update.
