Good idea, there are so many types of tweening to choose from.
I dug up a cool gif I saw on Twitter last month. Maybe others will find this helpful.
Yeah I thought you could try sth like 3rd in bottom row.
I've also seen this a few days ago.
Okay, so I tried a few, but tweening between 16 pixels in a pixel perfect way is pretty challenging.
I ended up setting up an array for the values to move by. So in the case of Easy Ease, the distance moved per frame is this: [ 1, 1, 2, 2, 3, 3, 4] While Easy Ease Out is more like: [1, 2, 3, 3, 4, 2, 1]
I guess best to have him slow down at the end of movement so controls feel responsive.
Great work, are you planning to add some story?
I like Easy Ease, because it brings a sort of impact to each step that I think works well in your genre.
Really really helpful reference gif for arty types and code monkeys alike.
