The Mega Engine is a free open-source Classic Mega Man engine for Game Maker Studio 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:
