Ranked in these QuestionsQuestion Ranking
Pro Intuitive drag & drop interface & visual event editor
CF2.5 uses a straightforward drag & drop editor that allows for easy level, animation and event creation without having to write a single line of code.
Pro Community-driven extensive object repository
Click Fusion has a great selection of extensions submitted by the community.
The extensions cover a variety of game-building tasks including parsing of strings using up to two alternating delimiters using the "Tokenizer Object", generating random numbers without reusing them from multiple lists which can be refilled and distinctively replenished with the "Random Multipool Object" among others.
Pro Export native runtime for all platforms
Be it Windows EXE, Android APK, iOS, HTML5 and Flash SWF, Fusion 2.5 is able to export your game to fast, truly native runtime for specified platform with a click.
Runs well under high object numbers, particularly on PC and iOS thanks to hardware acceleration.
Pro Box2D physics engine included on all platforms
Clickteam Fusion 2.5 brings to you the box2D physics engine.
Pro Not only is it the best, it is the original
This software has been around since 1994 (then called Klik & Play) and is still going very strong. Also, one of the founders of Clickteam was the developer of STOS BASIC and AMOS BASIC for the Atari ST and Amiga computers.
Pro Can also create Windows applications
CF allows creating Windows applications. Additionally, due to hundreds of available extensions, the process is quick.
Pro Upgrade discounts
If you buy Fusion 2.5, and later decide you want to upgrade to the Developer version, or in the case of moving from MMF2 to F2.5, the company offers upgrade discounts.
Pro Free version
Pro Supportive, passionate community
Any time you have a question or a problem, the community and the software developers are there to help you out either on forums or steam. The devs repond quickly to private messages or instantly on ClickConverse (chat). Additionally, many users have support sites with open source examples and tutorials.
Pro Permissive runtime license agreement
With the Developer edition of the product, there are absolutely no limits or requirements when selling your creations. You are free to make as much money as you want (this applies to the Standard edition too), and you don't have to include any logos or credits in your creations.
Pro Developers work so closely with the user base
Dedicated Bug tracking system linked to user forum for ease of access.
Pro Balanced feature set
An excellent compromise between ease of use, power, flexibility and ability to export to different platforms. Easy to learn for beginners with the ability to make complex things, of course, at the expense of a larger effort. Good rapid application development tool for making 2D games.
Pro Great IRL user events
Clickteam holds user conventions for customers to come along, meet the staff and hang out with people who they've met online. This furthers the community spirit which is so prevalent around Clickteam's products and it's a fantastic weekend.
Pro A great unofficial community for Spanish-speaking users
A great community in Spanish where you will receive all the help you need to solve your doubts and problems. You'll also find all kinds of resources and materials in Spanish.
Una gran comunidad en español en donde recibirás toda la ayuda que necesites para solucionar tus dudas y problemas. También encontrarás todo tipo de recursos, tutoriales y ejemplos en español.
Have used fusion 2.5 through all of its iterations, even when it was owned by imsi as CNC ( click n create ) it has been very stable and projects have been known to run on almost any Windows based computer. The projects you create even run on future versions of Windows with never many issues.
Pro Great online store to get free and paid assets
Pro Exports native mobile code, making great performance games
Pro Great for non-game apps, such as tools, utilities, multimedia projects, etc.
Pro Great formula editor, which allows you to create complex maths and events with ease
Pro Box2D physics engine
Pro Can create custom extensions
Pro Visual (HLSL) effects
Con Some features are really outdated and major updates are few and rare
There are some features that could make the software a lot more powerful but Clickteam does not have the staff resources to handle updating the software to be competitive with similar software.
Con Its Event Editor can be cumbersome if you are working on complex projects
While Fusion's visual programming event system is great to simplify things, it can be much more cumbersome to work with it than reading lines of code when you are working on a complex project. Especially if your events involve many nested conditions and lots of objects on the frame.
You are able to group events and objects, but it doesn't help at all if there's lots of conditions on an event and it becomes pretty hard to read.
Con Many extensions not available on non-Windows platforms
A lot of community-made extensions are only written for Windows, making it hard to port your game to other platforms.
Con Need to copy & paste events into every frame
Events are not shared globally across multiple frames. In order to have the player going from one frame to the other, you need to copy and paste all the code from one frame to the other.
This is obviously very tedious and time consuming.
Con Many event 'gotchas', especially with object selection
Many events have very unpredictable selection behavior, e.g. the 'Create' action (where the selection depends on whether a selection list already exists).
There is also a lot of subtle selection behavior, e.g. implicit object pairs for actions when an object is used in an expression.
Con Windows-Only development
Only Windows machines can be used to develop with.
Con No animation/object hierarchy
You need to position/rotate objects manually.
Con Cannot script editor
You cannot script the IDE or editor with e.g. macros or custom functionality, like you can in other popular game engines.
Con Need to write C++ extensions when existing extensions don't cut it
If you need e.g. a Steamworks extension or 3D display extension, you need to move out from the event system and create extensions in C++ with a cumbersome API. Fusion does not have FFI calls like other programming languages
Con Slow event system
Since the event system is interpreted, complex frames will start to slow down. This is also caused by poor code reuse, as usually, you need to copy+paste events with new conditions, making it impossible to cache intermediate results.
Con Poor native movements
The native non-physical movements are practically unusable if you don't want to use Box2D physics in your game.
