Sonic Lost World Style Running?

Hello And I Was Wondering If It's Possible To Make Sonic Like He Did In Sonic Lost World.

You're going to have to clarify. Do you mean you want to be able to assign a "run" button?

If so, that should be possible with a Lua script, where you toggle the character's max run speed based on whether a button is held down or not. Someone else might be able to give you better specifics.

If you mean, like, parkour, that would probably be a lot more complicated.

I Want Change The Running Cycle To Sonic Lost World Running Cycle.

If you're talking about changing the animation, then you just have to make the sprites for it and put them in a character wad. The wiki has tutorials for the technical aspects of getting your sprites in the game, but making the art itself is up to you.

Also, speaking as a mod here, use proper capitalization. Making Every Single Word Begin With A Capital Letter Is Annoying And You Should Instead Spend That Time Writing Posts That More Thoroughly Communicate What You Want To Say, With Better Proofreading.

To be fair to the user, it looks like he's looking for sprites that seem to fit similar to an old 2.0 mod. This mod replaces Sonic's running frames with new custom ones.

Duon, as far as I remember ye old Heroes Adventure mod, this running animation is kinda more "Modern Oriented". Sonic Lost World's is kinda a mix of Classic (for the legs) and Modern (for the arms) Sonic.
