Solarus 1.3 is out, now with a sprite editor!

UPDATE: a bugfix version 1.3.1 was just released. It fixes an error when opening a newly created sprite, and improves the sorting of resources with numbers in their id in the quest tree.

A new release of Solarus is available: version 1.3!

The main improvement of Solarus 1.3 is the graphical sprite editor integrated in Solarus Quest Editor. You will no longer have to edit sprite sheet data files by hand!

Sprite Editor

Screenshot of Solarus Quest Editor 1.3, modifying the sprite of an enemy in ZSDX.

The sprite editor was primarily developed by Maxs. You can create and edit sprite sheets. A tree shows the hierarchy of animations and direction of your sprite. And below the tree, you can edit the animation and direction that are selected in the tree.

The main changes of this release are in the quest editor. Another important improvement is that tile patterns can now be identified by a string instead of auto-generated integers. This allows to more easily maintain different similar tilesets.

There are also a few new features in the engine and in the Lua API, like more customizable switches, but nothing that breaks compatibility of your scripts.

As always, our games ZSDX and ZSXD were also upgraded to give you up-to-date examples of games. In ZSDX, there is also a new world minimap made by Neovyse.

Here is the full changelog.

English tutorial!

More and more people are interested in creating games with Solarus. However, there was a lack of tutorials to explain how to do it.

There is a video tutorial in French, and a written tutorial also in French, but so far there was nothing in English. You guys were expecting it, here it is: the official English video tutorial!

I uploaded chapter 1 today, and more chapters will come in the next few days. The French tutorial has 55 episodes for now (and is not over!) so there is a lot of work! To get the updates, you can follow me on Twitter (@ChristophoZS) or subscribe to the YouTube channel.

We hope that you will enjoy these videos and more importantly, that you will be able to create lots of great games now :)

Bugfix release 1.2.1

A bugfix release named Solarus 1.2.1 is available!

It addresses a few issues with recent features that were not working correctly, like custom entities, and a problem of corrupted image when creating a new quest with the editor.

  • Fix crash when an NPC sprite does not have 4 directions (#510). By Maxs1789.

Custom entities

If you are developing a quest with Solarus, you will definitely be interested in lots of new features of Solarus 1.2. But the most important one is probably custom entities!

Assume that you want to block the entrance of a dungeon with a big rock. To create your big rock on your map, you have to choose the type of map entity that best fits your needs. But each type of entity (non-playing character, enemy, door, destructible, dynamic tile, etc.) implements some built-in behavior that you don’t want for this particular need. Each type of entity corresponds to a common use case that is not necessarily yours in this situation. Sometimes, you can hijack an entity to avoid its built-in behavior: for example, you can implement the rock as a non-playing character that does not talk. Or you can make an enemy that does not hurt the hero. This is weird at best.

Another example is creating weapons that are not included in the engine. The engine implements a bow with arrows, the boomerang and the hookshot, similarly to Zelda: A Link to the Past. But how to create the hammer? More difficult: how to create the stakes that can be pushed using the hammer? How to shoot ice when using the ice rod?

Custom entities are the answer to these challenges. Custom entities are a new type of map entity introduced in Solarus 1.2.

Their main feature is to have no special feature! Indeed, they are fully scripted. Your script can define the size, the sprite (if any), the movement (if any) and the exact obstacle and collision rules. You can set callbacks to be executed when a collision is detected with another entity. In short, they are very powerful.

Lots of other built-in entity types could even be reimplemented as custom entities. Yet, we keep them because they are commonly used in games.

Let’s see how we could implement our big rock to block the entrance of a dungeon. From the editor, create on your map a custom entity called “rock_entrance”, set its size, for example 32×32, and its sprite to “entities/rock_entrance”. Indeed, common properties like the size and the sprite can be set from the editor. This is also possible from the Lua script of your map, but using the editor to create entities is easier. Then, edit the map script to define the other properties:

1
2
3
4
5
6
7
8
9
10
rock_entrance:set_traversable_by(false)  -- Don't allow other entities to traverse the rock.

-- Destroy the rock if there is an explosion.
rock_entrance:add_collision_test("overlapping", function(rock_entrance, other)
  if other:get_type() == "explosion" then
    -- The rock explodes.
    sol.audio.play_sound("secret")
    rock_entrance:remove()
  end
end)

This is a basic example of custom entity. To implement the hammer and hammer stakes, you will need two custom entities: the hammer itself (created dynamically when the player uses the item) and the hammer stakes. The hammer will test collisions with enemies and with hammer stakes. Hammer stakes will become traversable (and their sprite animation will change) when they collide with the hammer.

An interesting fact is that there will a lot of hammer stakes in your quest, and they will appear on different maps. In other words, you need a reusable custom entity. To solve this problem, we provide models: each custom entity can have an optional model. A model the name of a Lua script that will be applied to all custom entities that refer to it. Actually, this works exactly like the breed of enemies. You can have several enemies ruled by the same enemy script. Similarly, if you need multiple instances of identical custom entities, you can use a model.

Solarus 1.2 is out!

After six months of development, we are proud to announce the release of the Solarus 1.2!

Solarus now uses SDL2. Graphics are GPU-accelerated if available. Switching to fullscreen is faster, does not change the resolution and keeps the correct pixel ratio.  And the window is resizable. There are new pixel scaling filters, including hq4x which is great to play on big screens.

We now support LuaJIT, the just-in-time Lua compiler. Combined with the accelerated graphics of SDL2, we obtain better performance than ever.

But if you are a quest maker, you will especially be interested by custom entitiesstreams (the new name of conveyor belts), metatables and repeatable timers. I will give more details about these new features in future posts, but you can already see the documentation.

The quest editor was greatly improved. You can now resize multiple entities at once. The map view can be dragged with the middle mouse button and can be zoomed with Ctrl+wheel. Copy-pasting is more intuitive now, and works much better between different maps.

Our games ZSDX and ZSXD were also upgraded to give you up-to-date examples of games. ZSXD is now available in Spanish (beta). Thanks Xexio!

Here is the full changelog. 153 github issues were resolved for Solarus 1.2 (this is a new record!) and 20 more for ZSDX and ZSXD 1.8.

New design for the development blog

As the project grows and gets bigger, we thought it was important to get a new design for the development blog. Here it is ! We merged some pages to simplify navigation and changed the wordpress theme to a customized version of the very nice Vantage theme by SiteOrigin.

Solarus is about to be released in its 1.2 version, so let’s say the new design is to celebrate the soon-to-come event !

Solarus 1.1.1 released, fixed wrong teletransportation

An update of Solarus, Zelda Mystery of Solarus DX and XD was just released!

The main problem was a bug in Billy’s cave in ZSDX. You could be teletransported wrongly to a place that you were not supposed to see so early in the game, and more importantly, you could get stuck if you saved at that place. If you have this problem, just download the new version of ZSDX and your savegame will automatically get fixed.

Other annoying issues were fixed, including the heart meter not always updated and the game failing to detect the death of enemies falling into holes.

Changes in Solarus 1.1.1

  • Fix teletransporters activated while coming back from falling (#346).
  • Fix a libmodplug compilation problem due to wrong sndfile.h (#324).
  • Fix enemy death detection when falling into hole, lava or water (#350).
  • Fix a crash when changing the hero state in block:on_moved (#340).

Changes in Zelda Mystery of Solarus DX 1.7.1

  • Fix the heart meter not updated until the first save/reload (#67).
  • Fix wrong teletransportation in Billy’s cave after falling in a hole (#66).
  • Fix the debugging console no longer working after using F1, F2 or F3.

Changes in Zelda Mystery of Solarus XD 1.7.1

  • Fix Creepers never exploding after they are hurt (#16).
  • Fix a typo in English dialogs.
  • Fix the debugging console no longer working after using F1, F2 or F3

As always, you can install both games to replace any previous version and your savegames will continue to work.

Thank you for your feedback!

Android, Pandora and GCW-Zero ports!

Solarus 1.1 now officially supports three new mobile systems!

You have been waiting for a long time for the Android version. Thanks to Sam101, our games are now officially ported to Android. This Android port is in beta-testing though. There are a lot of different phone models so we need your feedback to know if there are problems. Please post any issue on the forum.

The Pandora and the GCW-Zero are two open-source consoles that are oriented to homebrew and retrogaming. Their communities are very active and thanks to their work, Solarus now also works on these two systems!

Therefore, the list of (offically) supported systems is now: Windows, Linux, Mac OS X, OpenBSD, Amiga OS 4, Android, Pandora, GCW-Zero.

See the download pages to get the games on the system of your choice.

We are also thinking of an iOS port with touchscreen gameplay but this will take time. Not only we have to upgrade the engine and the Lua API to handle the mouse and the touchscreens, but we also need to completely rework the gameplay in the case when no physical button is available. So how do we do right now for the Android version? We actually use a trick: the SDL 1.2 port of Android adds virtual buttons to the screen, that are mapped to SDL keyboard keys.

Solarus 1.1 released!

The new version of Solarus is available now!

The main change of Solarus 1.1 is that there are no more hardcoded menus in the engine: the dialog box and the game-over menu are now fully scripted in your quest with the Lua API. There are a lot of other new features and improvements, as well as bug fixes, so it is recommended to upgrade.

Our games ZSDX and ZSXD were also upgraded to give you up-to-date examples of games. ZSDX is now available in simplified Chinese and traditional Chinese (beta). Thanks Sundae and Rypervenche! Note that a Spanish version of ZSXD is also in progress (thanks Xexio!).

Solarus 1.1 also improves portability and performance. This allows us to release the Android and OpenPandora versions of our games. They will be available in the next few days!

Here is the full changelog. 80 github issues were resolved for Solarus 1.1 and 20 more for ZSDX and ZSXD 1.7 so this is a huge list!

Incompatibilities

These improvements involve changes that introduce some incompatibilities in both the format of data files (sprites, project_db.dat, languages.dat) and the Lua API (the dialog box and the game-over menu are scripted now!). Make a backup, and then see the migration guide on the wiki to know how to upgrade.

Customizable game-over menu!

The last built-in menu is not built-in anymore in Solarus 1.1!

Now, when the life of the player reaches zero, an event game:on_game_over_started() is called. The game is suspended and you can show whatever you want. You can make a dialog that lets the player chose between “Continue” or “Save and quit”. Or you can make a more elaborate game-over menu like in our games, where a fairy saves the player if he has one in a bottle.

And if you don’t define the event, game:on_game_over_started(), then the engine just restarts the game.

The Solarus 1.1 roadmap is close to its end. 50 issues were solved and 1 is still open. Now I am testing both games (ZSDX and ZSXD) to check everything because there was some refactoring done to upgrade to Solarus 1.1, and some C++ code was replaced by Lua code (most importantly, the dialog box and the game-over menu).
