The Mega Engine is a free open-source Classic Mega Man engine for Game Maker Studio 2, Game Maker Studio 1.4 and Game Maker 8.1, built around the idea of combining accuracy to the original games with being flexible and easy-to-use. It aims to take the best of all entries in the Classic series and combining it in one engine. Being built from the ground up, this engine is the result of three months of work; while this may seem like a short development time, I did not cut any corners in regards to quality.

The engine has several features, including:
  • 60 FPS Classic Mega Man gameplay
  • Flexibility in adding or changing content in the engine
  • Accurate movement, physics, object interaction and more
  • Sliding and buster charging (can be disabled with ease)
  • Collision with solids, jumpthrough solids, ladders, spikes and water
  • A “section system” as present in the Classic titles, including proper screen transitions
  • Several built-in special weapons, with flexibility in adding new ones or changing existing ones
  • Built-in enemies, as well as flexibility in adding your own
  • Three example gimmicks included in the engine, and flexibility in adding your own
  • An example Robot Master with full AI, and flexibility to add your own bosses
  • A customizable title screen, stage select, boss introduction screen, weapon get screen, game over screen and pause screen
  • E-Tanks, M-Tanks, health drops, weapon drops and extra lives
  • Fully functional checkpoints

To make this engine as easy to use as I could, I made a video tutorial series on how to use the engine. A playlist of the series can be found here: http://bit.ly/2bc7HQE

I also recorded an engine playthrough to showcase most of the features it has:

F.A.Q.
Q: Why would I use this engine over other Game Maker engines?
A: Most engines tend to try and accomplish only what is necessary for the example level(s) and do not consider flexibility and ease of use; the Mega Engine does account for all that. Plus, this engine is fully compatible with Game Maker Studio, unlike most other engines.

Q: What is the engine’s frame rate?
A: The engine runs at 60 frames per second (assuming your PC can handle it, of course)

Q: I don’t want sliding and/or buster charging in my game. How do I disable them?
A: Go to Objects > Player > objGlobalControl and open the Create event code. Upon scrolling down, you will encounter a section called “Option variables”. Here you will see the variables global.enableCharge and global.enableSlide. Set either of them to false to disable the ability.

Q: Where can I view the credits of the game?
A: The credits can be found in the Game Information.

Q: I ran into a bug! How do I report it?
A: Bug reporting is very appreciated! You can either post a message in this thread or send me a private message to report bugs. I will make sure to check both this thread and my private messages regularly.

Q: I have an idea or suggestion for the engine, where do I post it?
A: Ideas, suggestions, feedback and criticism are always welcome. Please post them in this thread or send me a private message.

goddamn

this engine is perfect. that's all i can say.
Dude this is a FANTASTIC engine. It's already going to be used in the Mega Man 1 Remake and Mega Man FU.

Wait, really? That's awesome. Both projects sound promising, so I'm honoured that my engine will be used for them!
As the director and general manager for Mega Man FU, I can confirm FU will use this engine. All due credit will be given as well.
Holy moly. This engine is amazing, and exactly what I've been looking for a while.

Thank you WreckingGoomba.
Exciting!!!

I can't look at this engine right now, but I've been making an open source Mega Man engine myself in Java partly as a learning experience, and just going off of people's opinions so far I bet this engine has a lot of great stuff that could help me out. Thank you!
one word: MEGA. as in good. Im sorry everyone.

Ya know I never though I'd see a mega man engine other than blyka's old one. After playing around with this one I have to say it's VERY solid. I can see ALOT of great fan games being made with this. Sorry about double posting by the way, some people find that annoying.
The GM 8.1 engine has errors like with the wall moving things. If you fix these glitchs, This engine will be amazing!
tried out the engine, feels extremely solid so far I was actually pretty surprised.

if I could make a suggestion it would be to add an example shield weapon that can block projectiles since almost every mega man game's had a shield in some form or another.
also after doing a bit of messing around, you didn't really showcase that the engine was cable of vertical scrolling, I'd suggest doing it where you encounter the big eye since you start at the highest point of the room in the conveyor belt section.

Look forward to seeing things made with this.
Thanks for the feedback everyone!

Hmm, I never encountered any problems with that myself. Could you explain the problem in more detail?

That's a pretty good idea, thanks. I'll make sure to add some kind of shield weapon in the next version!

Vertical scrolling was not showcased as the 8-bit games did not have it. The fact that it works actually surprises me, as I've never tested it out, but it's good to know, so thanks for mentioning!
Nice demostration of the Mega Engine
I used the GM 8.1 to GM 8 tool so that might be the problem.

That's probably it, then. Someone else tested that for me as well and encountered numerous issues, which are most likely being caused by the fact that this engine is not made to be compatible with GM 8.0.
If you really want to use this engine, the Standard version (which can do everything you want) of Game Maker Studio is free, and the engine is fully compatible with that version of Studio.
My computer isn't compadable with Studio. Thanks but I'll stick with Blyka's engine. Sorry Sad
Taking a look at the engine, it seems very robust and quite extendable.

Now, if only Game Maker Studio's SpiceIDE stopped crashing all the time...

EDIT: Never mind, I was able to dig up a copy of GM 8.1. Works fine there!

Great job Wrecking!

Could we also contribute features to this engine as well? On my build, I have Bladers and Tellies working, a dedicated slide button, and floating damage numbers (like Super Fighting Robot).
Hey there WreckingPrograms, i'm ScoopJohn from YouTube. I realized i had left my Sprites Inc. account here so i just went to post here to see how it goes. Glad i'm not late to the fun! Big Grin
