Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Great tech support and friendly community
A growing community that is always helpful with dev response times averaging less then 24 hours. Often less than 12.
Pro Comprehensive WYSIWYG editor
Skyline provides a straightforward drag and drop development environment that can be customized to suit individual preferences. Playing the game and animating the scene can be done from within the editor at any time.
Future versions will allow extending editor's functionality with plugins and offer an official way of trading custom plugins.
Pro Highly affordable licensing
Skyline's commercial edition costs just £40, has no royalties or earning limitations and includes 2 activations per license purchase and a year of free updates.
Pro Runs well on lower end machines
Skyline can be run on a machine with 2GHz Dual Core CPU, 2GB of RAM and Nvidia's 9800 GT (or equivalent) GPU. While, obviously, higher specs are recommended, it's reasonable to expect around 60fps on small scenes with these specs.
Pro Excellent terrain editor
The Terrain editor is easy to use and will include features such as hole cutting.
There is a differed lighting render for internal scenes, which makes creating multi light and beautiful/atmospheric scenes so much easier.
All the tools for the terrain are in one place such as placing road/paths, vegetation, billboards, and the settings are easy to locate and change.
Planned features include:
Hole cutting in terrain and
Terrain paging.
Pro Low learning curve
Making a game in the current top engines is hard work, making something small and basic in Skyline is not. Easy to learn drag an drop model placement and editing supplemented with easy to follow video's on forum make the process straightforward.
Pro Full global illumination
Including image based lighting.
Pro Has a free version
A free version that's limited to non-commercial usage and lacks a few features is available.
Pro Impressive water render
Rendering of a water plane looks fantastic and is easily edited for different effects.
Pro Artist-friendly
The schematic editor is designed to make it easier for non-programmers to create games.
Pro Asset store
Not much in it at the moment but is starting to grow and will continue to grow with an increase of users.
Pro Constant development and regular updates
There are many additions to the engine that are on the road map such as multi threading and tree physics.
The feature list is constantly evolving with each user request and idea put forth.
Pro Support for custom editors
Skyline has a custom editor that gives the user of making their own tools for use directly in the editor to develop their games. All the editors are made using the Qt Designer and programmed in lua inside the engine itself.
Pro OSVR support announced
Open-Source Virtual Reality support is in development.
Pro More editor's
Shadow editor.
Weapon Class Editor.
Mesh Editor.
Advanced Mesh Editor.
GUI Editor.
Script Editor.
Environment Editor (volumetric clouds and day night cycle, lightening, ocean settings, height fog).
Particle Editor.
Path editor.
Schematic editor.
Navmesh editor.
Material editor.
Pro Lots of learning resources
The documentation is been rewritten and follows a structure like a course.
Introduction to > Level designer with examples > Artists
There is also video tutorials, video examples and video tutorial series been produced.
There are user created demo scenes, examples and more.
Pro Visual GUI/HUD Dditor
Making HUDs and GUIs has never been easier
Pro PBR Workflow
Full PBR workflow, your not stuck to Secular or Metallic it has both
Pro One on one private support with engine developers
Can contact the Skyline developers and they will always respond and help as fast as they can.
Pro Beginner-friendly
ct.js is bundled with examples, docs, and easy to follow tutorials. Documentation and tutorials are available in a side panel on every screen.
Pro Skeletal animations with DragonBones support
You can import skeletal sprites and animations from DragonBones, which is also free. Skeletal animations are added to objects through code; developers can listen to marked events in animation, and ct.js automatically associates sounds in a DragonBones project with the game's assets.
Pro Good code editor
The built-in code editor comes with error checking, type checks, code completions accompanied with docs, multiple cursors support, and other modern features.
Pro Open source (MIT)
This means that no one will ever put any features behind a paywall and that you can reliably use ct.js in any projects without worrying about licensing. And you can hack on ct.js!
The repo is at https://github.com/ct-js/ct-js
Pro Tileset support
ct.js supports tiles in rooms, including collision checks and some extra editor tools, like bulk migration to a new tile layer or shifting by an exact value.
Pro WebGL and WebGL2 support
Starting with v1.0.0-next-1, you can now write WebGL games. WebGL support is based on Pixi.js.
Pro Modular approach
ct.js has a "Core" library that provides basic drawing functions, room and asset management, and mouse interactions. Any other functions are added to projects as "catmods", or simply modules. These modules can be enabled or disabled in one click, and can inject their code in different game loop stages, e.g. after drawing all the objects, leaving a room, or when a new object is created.
Pro Applicable to most genres
ct.js aims to be a general game engine and provides tools in making games of any genre.
Pro Dialogue and visual novel system with support for Yarn
A module ct.yarn allows developers to import a YarnSpinner project to create branching, data-driven dialogues and visual novels. An example is also bundled with ct.js.
The dialogue tree is made in a separate app, though.
Pro Real-time particle system editor
v1.3 brings a particle system editor, which displays a preview sprite for proper attachment of emitter to visual elements, and allows combining more than one emitter with different particles into one effect. With these, even the creation of complex, multi-step effects becomes easy. The editor comes with dozens ready-made textures for faster prototyping.
Cons
Con Currently limited to targeting PC
Mobile targets are planned.
Con Free Version currently not available/severely limited when available.
The free version has massive amounts of features functionality removed, including the ability to compile anything standalone.
The free version is currently (as of November 2017) not available until the next major release.
Note: some of what is below is open to change, this is the coming set of changes.
The price will be jumping from $40 to £99.99 ($132.32) for the lowest tier able to build a standalone. This tier will not be able to remove the engine splash screen.
The next tier will be £199.99 ($264.66).
Con No C++ SDK
Con Small community
There is a small but helpful community that are constantly creating video tutorials and one member is creating a FREE ebook to make the transition to the engine simpler.
Con Still in beta
Not all features are fully implemented yet.
Con Lacks occlusion culling and lightmapping
This is been added in a future update, however a date of this update hasn't been given yet.
Con Tile editing is a chore
No live brushes with automatic corner drawing, no fills or rectangular/linear placement. All tiles should be placed by hand, with a "Shift" key to place multiple tiles at once. This will make you ragequit if you want to make sophisticated RPG scenes :D
Con Slower than native games
JavaScript and WebGL are fast, but they will always lose in performance if compared to native games, so it may be a bad choice for graphics-heavy games.
