I am familiarizing myself with U4 ver. 4.22 and doing the tutorial “Animation Blueprint Event Graph”. While it seems that the tutorial based on a lower version of Unity, I am clueless about where the “Set Is In Air” action; or, has Unity removed that feature from later versions of Unity.
The Is In Air? check result in contained in the Movement Component of pawns. It’s an automated check that returns a Bool value.
