New Generation: Geography Engine Ultimate


Geography Engine is the second half-originally developed MF engine developed by Electronic Boy, released on Nov. 14th, 2020, which is also the first engine that he developed from zero.

Compared with two other engine he has developed - Cauldron Engine and Star Engine, Geography Engine contains fleshed-out values-strings-foreach system, which makes developers who have mastered the usage of the values, strings and foreaches create DIY elements more conveniently and flexibly.

In March, 2021, due to plenty of glitches and mistakes happening on the Engine, it made the author have to remake it again, which was eventually released on May 14th, 2021 (Public Beta Edition, and there is a serious bug with CTF2.5+ confirmed by Clickteam)

In November 13th, 2021, the day of the 1st anniversary of Geography Engine getting released, the author released its version of b0.10.0, with quite a number of changes

NOTE: Due to trillions of changes have been resorted to the trunk events of the engine, the engine doesn't belong to any engine system, and it should be a novel category of level editor engines.

Advantages & Disadvantages


  • Traditional coding mode with behaviors and unique module linking function.
  • More flexible and accurate objects, and more comfortable player handling.
  • More direct object placing, such as the placement of bonus blocks and pipe warps.
  • Multiple players in single-player game is supported (this can be achieved via specific methods in the version b0.9, which needs every developer to do research on it)
  • Custom camera views are supported(usage is the same as what UEL does)
  • Custom parameters for player, increasing the gameplay(New from b0.8)


  • Due to quite a number of functions and handling of interfaces, it takes quite energy for those who want to develop more more creatively to take in relative codes.
  • High density of codes and high connection among functions make users use a bit inconveniently.
  • Some key factors will cause crashes easily (Please see "Introduction" to get more details, now it's temporarily fixed and it's not clarified how stable it will be)

Written on Nov. 14th, 2020

The original intention to develop the engine is that I saw there are quite a lot of problems with users using RE, including Stucking Wall and poor position fixing. To fix them, and inspired by No-detector detect by Dasasdhba and dealing with Star Engine before, I, then, opened my laptop in the evening on Oct. 14th, 2020, and my Clickteam Fusion Developer 2.5+, starting my project... From primary "Application 1" to "Geography Engine", it had been almost 4 weeks due Nov. 15th, 2020, and worked on it at least 4 hours a day. So I went to bed till almost 0 o'clock these days.

However, the development was quite curvy. Because it's my first time to start from zero, I used my catty-hands to code them, and with that crazy idea began it. Yet what I think firstly remained thought, with reality more out of expection: Numbers of bugs came out continuously, lots of codes should be back to the furnace, and high reading of codes made it uncomfortable... But still, I thought if gave up, the effort were to be in the running sea. To that, I specially thank Dasasdhba that in my forehalf of development, when I asked him for help, he basically accept them and helped me with bugs and codes...With he taking his avaliable time to help me in such high pressure of study, I thought it irritating but appreciating - What was irritating was that I hurt his tree of study, but what was appreciating was that I obtained my skill upgraded with his help and my looping trying.

Finally she got her flamboyant dress, having came out on Nov. 14th, 2020

Hope this heart-fulfilled engine, developed almost from zero, could help more Mario Forever fangame makers reach their own dream of MF.

It's Mid-autumn Festival. May everyone have a full, united and fortune day and enjoy the festival together

Although the engine was remade in March this year for some reasons, even though it has been remade, it still lacks of users heavily

I, personally and sincerely, have spent quantities of time on this engine, but the result does hurt me more or less

Indeed, even though the Geography Engine has been remade, its core changes still exist, especially the reverse gravity system. In some version, where the interfaces of or related to reverse gravity, that system was removed. Then after my awareness on some engines, I still kept my first-determination, and re-added it into b0.7 with more stability and have been coordinating it with other systems, making it another engine with multi-gravity after Ultra Engine Legacy.(Someone will ask me: why not try 360° gravity? I just wanna answer: Why not UEL in CTF, lol)

However, I firmly believe that in the future, no matter which game-making platform like Game Maker or Unity, those who still hope to make games with CTF can proudly say: GER comforted me and makes my game-making convenient.

Time for the Lunar New Year, and may everyone lucky in the year symbolizing tiger(虎年吉祥), may you healthy(身体健康), may your work going well(万事如意), and may your family happy and fortune(阖家幸福)

Although the Pandemic has brought us globe of pains, it also brought us more challenges. Due to COVID-19 going about, much more people have to be online for work and life. I'm not the exception and have been keeping spending 12 hours or so on my computers and my phone per day, for which I have received lots of quarreling education from my parents.

Meanwhile, I haven't stopped my step on MF fangames and engines, especially...

Especially, I plan to publish an edition of GER that has been arranged and modified -- Geography Engine Ultimate

Compared with GER, GEU has values of qualifiers, whose importance may affect their value sections. The more important the qualifier is, the former the values will be, and the latter the other values will be on the contrary. Also, to get the arrangement and reputable naming better, I've got to defined a series of naming rules adjusting to GEU: The values beginning with capital letters are global, ones beginning with underlines( _ ) are partial or unusable values, the flags(booleans) should be named with Camel-Case, the names of fastloops should begin with "$" and the ones of foreaches start with "#", etc. Via this, as long as the users get used to these rules, they will soon understand what functions what, which are usable while which unusable, and which are global while which are partial, and so on.

I hope this year it would be great to see more people get conveniences and applications from GEU, and make those who just adjust to Clickteam Fusion 2.5+ enjoy the feeling of coding close to ones as if you were a real coder
