Hey ajgarces_1!
Could we get some screenshots to see how you have your Update Animation and Set Flipbook functions set up?
For instance, you could be using a state machine to determine the state of the character and outputting animation through functions, as opposed to the event graph. If you’re simply using Update Animation and Set Flipbook based solely on an Enum to determine what animation to set to the sprite you’ll need to add a DoubleJump option in the Enum.
Click here for Paper animation documentation if you haven’t looked at it yet. It’s an example of one way to do things, if you did it this way you’ll need to add an Enum entry on your state machine to be a Double Jump and make a new function to set the animation, similar to the jump notated there but checking for double jump instead and referencing another flipbook.
There are many ways to set up a sprite! Once we get those screenshots we can get that figured out for your specific project setup!
