A remix of my own project Holy Cheese! In this remix I've stripped away everything but the Player animation, and I've added a Sine curve to illustrate how the running is animated using the Sine function. Every cycle, the variable "Animation" is incremented by "Speed". When it reaches 360, it starts again at 0. The Sine of "Animation" is used to calculate the length of the Players arms and so forth. Set speed to 2, and keep your eye on the right leg, and I think you'll see it. See inside. All code by me (@kriblo). The jump sound is from the Scratch Library. The footsteps sound is from MineCraft (stepping on slime block).
