HELP i know that you have to use animation behavioru to get the 0player to look like running but how do i use it

You edit your sprite and click on the animation button (under the undo button)- a bar should appear at the top of your screen, hit pick animation, create new, and then add frames to make it look like they’re moving. You can also modify the delay between frames. After you finish, Behaviors-properties-animation. Once you put the behavior in, you can make it so that it only activates at certain times (e.g. when you jump) by connecting a trigger to the animation.
