Developer HOWTO Guides

Introduction

Before proceed read getting started guide about tools and project structure.

Below you can found howto guides or developer's checklist.

Add new card

1. Select card to implement (example: "Anvilwrought Raptor");
2. Find out all info about card (example from scryfall);
3. Make sure it's not implemented yet -- search source code for "card name";
4. Find old card with the same or similar abilities (use scryfall advanced oracle search or source code search);
5. Prepare empty card stub:
   • Create new java class file and copy paste source code any other card to it:
   • Rename java class to card name in Camel Case Notation without any special chars or spaces (example: Angrath, the Flame-Chained -> AngrathTheFlameChained);
   • Check out card type, cost and subtype of new card;
   • Remove not necessary abilities or code from old card;
6. Add card's abilities:
   • Use copy paste code from same card;
   • Change and setup that code to your cards, e.g. change filter or condition;
   • Use IDE code complete to hint correct class and method access (they all have same names as they describe on card. Example for flying ability: this.addAbility(FlyingAbility.getInstance()););
7. Add new card to set's list:
   • Find set's file in ..\Mage.Sets\src\mage\sets\YOUR_SET.java;
   • Card's list by alphabetically order;
   • Copy paste line from any other card near and change it to your card;
   • Check out card name, card number, card rarity and card class name;
8. All done, not time to test:
   • Restart test server and client from your source in test mode (see testing strategy info);
   • If xmage can't find your card name (see errors log or check it in deck editor) then delete all cards*.db files in developer folder -- it's force to recreate new database;
   • Make sure your card work fine and have same text as it have on paper (hint: if card's have wrong or missing text then ability settings was incorrect -- try to fix it first);
   • Run all xmage tests, they all must be green (see xmage testing tools);
   • Try to download card image (use xmage download images window for card's set);
9. Commit changes (new card file and changes set file) and pull request it.

Add new token

TODO

Add new set

1. Create new set's java file in ..\Mage.Sets\src\mage\sets\ folder by copy-paste template from any other set (example: ExplorersOfIxalan.java);
2. Setup official set code and release date (use scryfall for set's info);
3. Add new cards to set (see above);
4. Add new tokens to set (see above);
5. Setup set symbols download options:
   1. Go to ..\Mage.Client\src\main\java\org\mage\plugins\card\dl\sources\GathererSets.java;
   2. Add set's code to one of the supported list (example: symbolsBasic);
   3. Add replace code when source uses non standard codes (example: codeReplacements.put("CMA", "CM1"););
6. Setup card images download options:
   1. Find current supporting images sources DownloadSources in ..\Mage.Client\src\main\java\org\mage\plugins\card\images\DownloadPictures.java file;
   2. For each image source that you can download go to class file and add set's code to support list;
      1. Add set's code to supported (example for scryfall: supportedSets.add("OGW"););
      2. Add replace code when source uses non standard codes (example for scryfall: put("DD3GVL", "gvl"););
   3. If set's can be downloaded then remove that code from global ignore list (ignore.urls in C:\mage\Mage.Client\src\main\resources\image.url.properties file);
7. Setup token images download options:
   1. Some sources can support tokens download: if so then repeat cards images setup but search source code for tokens data (start with getTokenImages() method from java class, example: ..\Mage.Client\src\main\java\org\mage\plugins\card\dl\sources\TokensMtgImageSource.java);
   2. Add tokens data to ..\Mage.Client\src\main\resources\card-pictures-tok.txt;
   3. Find each new token class and add set's code to supported list tokenImageSets.addAll (example: ..\Mage\src\main\java\mage\game\permanent\token\SaprolingToken.java -- it's will help xmage to select token image on battlefield by set's priority (see image.url.properties file);

Test pull request

If you want to test other pull request before merge:

1. Go to pull request page and save it's number like #4306;
2. Open git and run command to fetch new pull request to new branch: git fetch origin pull/4306/head:test-pull-request where:

• origin -- name of the xmage repository (to find out it in IntellJ IDEA go to VCS -> Git -> Remotes);
• 4306 -- pull request number;
• test-pull-request -- temporary branch for test;

3. Open new created branch by checkout test-pull-request;
