SAGE 2022 - Framework The Rocket Engine


The Rocket Engine is a Sonic Engine (or Framework... I guess) for GameMaker: Studio 1 based on the Sonic Advance series, using the Harinezumi Engine as a template, that I've been working on for quite a while now.​

  • Mostly Advance 1-accurate physics.​
  • 4 playable characters: Sonic, Tails, Knuckles and Amy.​
  • All characters have their respective attacks and maneuvers.​
  • Chaos Emeralds (variables) are in: Super Sonic is playable.​
  • Background parallax system.​
  • Simple to understand: Based on Harinezumi / S8E, which is based on previous GameMaker Sonic engines, so the structure of the engine is pretty much the same.​
  • Rail grinding like in Advance​
  • Underwater system​
  • Capsule system.​
You can either get it from this page, or you can download it from GitHub.​



Bugs / glitches, or other stuff that I'm aware of:

  • The result screen tile/background warping, it's minor but I know it's noticeable. It can be fixed but I'm not entirely sure of how and it's just a test level so I'm sure if one were to use it normally they could figure out a solution to make it work better
  • The physics / some of the attacks may not be entirely accurate, but I'm still not a GameMaker expert, so please excuse me.
  • Grinding isn't the most functional...
  • When exporting the game, my PC kept detecting it as a virus and deleting it. There's a chance your PC or your browser might detect the exe as a virus. Do not worry, it's not a virus, I have no idea what even is triggering the anti-virus lol

Nice engine, I love advance 1, and id love to see what becomes of it in the future, like what fangames would be made in it or updates that make it even better than it already is.
New engines are always brilliant. Amazing work. Looking forward to see what people do with this. Also appreciate the simple name, makes understanding what engine people use a lot easier haha.
Nice seeing an engine based on Sonic Advance

btw amy's small hop and crouch are kinda off, she's supposed to slow down when crouching instead of stopping completely also the small hop should be able to give enough speed to go through a loop
