The “full-crouch” state in Tekken 7 (And most 3D games in general) is confusing for players transitioning from 2D to 3D fighting games. More specifically, many 2D players are unaware that the transitional stage between full-crouch and standing is its own state, with its own set of moves tied to it.
This state is known as “While-Standing” in Tekken (here’s a mnemonic for you: it happens while you’re standing up.) and sometimes “While-Rising” in other 3D games. If you’ve ever wondered why you tried to do one of your standing moves after you finished crouching and something else came out instead, you probably got a While-Standing move.
Though crouching and “While-Standing” moves are not inherently bad or good, there are real reasons why you may find yourself wanting to bypass both of these states to instantly get normal standing moves. In that case, you need to learn about crouch canceling, which is performed in Tekken 7 by using a sidestep to cancel your crouch. Check out FrameWhisperer Tekken‘s latest video for its execution, and practical examples for when to apply this important technique.
