By Lord-Knightmare

There are more than 450 add-ons available for 1.16 and this summer saw a lot of activity on the add-on server. Here are some of the highlights from what our user community has created.


An update to one of the most popular unofficial eras was released in late May. Era of Magic 3.8.3 brought us five more units and some exciting new treats, like the Mirrorshield's deflect magic ability. Now's a good time to revisit the Al-Kamija, the Kharos, and all the factions from Era of Magic.


This challenging campaign, which tells the history of the drakes and the secret to their inner fire, is now available for 1.16. Lead Herkarth and his people to the source of a mysterious power effecting the drakes deep in the ancient Heartfang mountains. With custom units, tricky puzzles, and easter eggs, this campaign brings much love to an under-played faction.


The team behind this growing era delivered a major update (1.4), with innovative new tactics like castle-breaking, unit-pulls and long-range attacks. They have also put together a short campaign, Ogre Crusaders, if you want to cut your teeth on something longer than a single scenario.



A true classic, this add-on may be the most well-written horse-back campaign ever and it's now available for 1.16. Command a cavalry force and use your mobility to outflank and defeat an unstoppable legion of cultists, soldiers, and creatures of the night.


This unique era features more than 200 historical units in more than a dozen factions inspired by 18th century warfare in Europe. A new major version was just released and the maintainers are looking for more contributors.


Another classic, this elven campaign is back after several years being unmaintained. It has been rebuilt to use units from the War of Legends era, and features dungeon-crawling scenarios and small-squad gameplay.


Follow these steps to install an add-on and play it.

1. From the main menu, click Add-ons.
2. Click Connect to join add-ons.wesnoth.org, the official add-on server.
3. Browse or search the list of add-ons.
4. Click on the add-on to read more about it.
5. Click to install the add-on.
6. Click Exit to return to the main menu.

Once your add-on is installed, you can play it like any other game of Wesnoth. Campaign add-ons can be found in the campaigns menu. Multiplayer eras and scenarios are available when you start a multiplayer game.


Every add-on starts with a good idea. Here's how to get started making your own maps, units, scenarios and campaigns.

• Generalized "lower terrain" similar to the mid-level in lava/chasm. Cosmetic and unwalkable versions. (PR #6927)

• Updated translations: Arabic, British English, Bulgarian, Chinese (Traditional), Czech, Finnish, French, Italian, Portuguese (Brazil)

• Fixed inconsistent cropping of unusually-sized item images (issue #6118)
  
• Fixed the `{IS_HERO}` macro to avoid losing the hero ellipse when a unit levels up
  
• Stored credentials are now encrypted with AES rather than RC4. This will result in credentials needing to be re-entered the first time when logging in with this version.

  • S8: Fixed replay OOS on victory event (issue #6267)

• New `wesnoth.interface.screen_fade` function applies an overlay colour to the game display, fading over the given duration (PR #6864).
  
• New functions have been added to register game events from Lua: `wesnoth.game_events.add`, `wesnoth.game_events.add_menu`, `wesnoth.game_events.add_repeating`, `wesnoth.game_events.add_wml`.
  • Both the action and the filter can now be a native Lua function, if needed.
    
  • All features of the `[event]` tag are available.
    
  • The primary API is `wesnoth.game_event.add` - the others are shortcuts for common use-cases.

• `wesnoth.game_events.fire` (renamed from `wesnoth.fire_event`) now supports passing unusual event-specific data such as damage in an attack event or previous owner in a village capture event.
  
• `wesnoth.fire_event_by_id` is renamed to `wesnoth.game_events.fire_by_id`.
  
• `wesnoth.current.event_context` now has an additional `data` attribute that contains the full event data, including the former owner in a village capture event (which was previously never exposed anywhere).
  
• `wesnoth.remove_event_handler` renamed to `wesnoth.game_events.remove` for consistency with other event functions.

• Increased minimum required version of SDL to 2.0.10 for non-macOS platforms.
  
• Increased minimum required version of SDL to 2.0.22 and the minimum required OS version to 10.12 for macOS due to needing the fix https://github.com/libsdl-org/SDL/commit/3bebdaccb7bff8c40438856081d404a7ce3def30.

• Large changes have been made to Wesnoth's rendering engine, enabling hardware acceleration for the majority of components and resolving many long-standing issues. Performance should be greatly increased, and CPU and GPU usage greatly decreased in almost all situations. Issues confirmed resolved: #1291, #1350, #1605, #1755, #2059, #2458, #2618, #2865, #3238, #3255, #3421, #3592, #3798, #3937, #4210, #4460, #4877, #5115, #5420, #5494.

• A new interface action `[screen_fade]` provides a smooth screen fade effect which also covers units (issue #6745).
  
• Events now support filter conditions using the Wesnoth Formula Language with a new `filter_formula` key.
  
• It is now possible for variable interpolation in an event name to expand to multiple event names - the name is split on commas both before and after variable interpolation.
  
• The `[fire_event]` tag now supports a `[data]` subtag that can be used to pass any arbitrary information to the event. In particular, it supports passing damage to an attack event and former owner to a village capture event.
