 == Air Step ==
-When an action performs an air step, the first thing Mario does is update his horizontal velocity/sideways position via [[straining]].
+''Certain things here are more explained on their individual pages. If something lacks detail, check the link for more information.''
+When an action performs a ''common'' air step, the first thing Mario does is update his horizontal velocity/sideways position via [[straining]]. This is only for the common air step and is not part of the quarter-frame checks.
+=== Quarter-Frame Checks ===
 After that is updated, the movement is split into "quarter-steps" that breakdown Mario's movement and determine what his outcome of each step is. The checks for the quarter-steps are as follows:
@@ Line 39: / Line 43: @@
 ## If no other exit has occurred, '''nothing happens'''.
 # This repeats until Mario encounters something besides '''nothing happens''', up to four times including the initial time.
+# Mario tracks his "exit", with '''nothing happens''' being tracked if the whole process completed four times.
+With the outcome selected and the movement mostly done, a series of things happen.
+* If Mario's velocity is not negative, his "peak height" is updated.
+* Mario's step noise is updated based on his floor.
+* If Mario is not flying, [[gravity]] is applied.
+* [[Vertical Wind|Vertical wind]] is now applied/accounted for.
+* Mario's visual position is updated to Mario's position.
+* Mario's yaw is updated to match the in-game angle.
-From here, the outcome chooses the next action and some other things are applied.
+=== Common Air Step Results ===
+If doing a common air step, Mario now decides what to do based off the "exit" from the quarter-frame checks before. Here is what he does for each exit:
+* '''Nothing Happens''':
+** Mario's animation is now applied.
+* '''Lands''':
+** If Mario is not over a hard [[surface]], the [[terrain]] is either snow or desert, Mario's peak height is more than 1000 units above him, the surface does not belong to an object, and the Y normal of the surface is not less than .8660254 (square root of 3 divided by 2):
+*** Mario plays an OOF noise, dependent on which [[Version Differences|version of the game]].
+*** Mario spawns particles.
+*** Mario's action is set to the [[Feet Stuck in Ground|feet stuck in ground]] action and the '''lands''' checks stop.
+** If Mario's action is not twirling, the floor is not lava, his negative velocity is less than -55, and the distance from the peak height to Mario is more than 3000 units:
+*** Mario is hurt by 16 (24 without his hat).
+*** The camera shakes.
+*** Mario plays the "attacked" noise.
+*** Mario is set to the [[Hard Backward Ground Knockback|hard backward ground knockback]] action and the '''lands''' checks stop.
+** If Mario's action is not twirling, the floor is not lava, his negative velocity is less than -55, and the distance from the peak height to Mario is more than 1150 units:
+*** Mario is hurt by 8 (12 without his hat).
+*** Mario is squished for 30.
+*** The camera shakes.
+*** Mario plays the "attacked" noise.
+** Mario is set to his action's landing action.
+* '''Hits a Wall''':
+** Mario's animation is now applied.
+** If Mario's forward velocity is more than 16 and is in contact with a physical wall/surface:
+*** Mario's yaw is "reflected" across the most recent wall Mario collided with, up to the first 4 walls. (This can be glitchy with more than 1 wall, i.e. [[Unreferenced Walls|unreferenced walls]]).
+*** Mario plays a noise depending on whether or not he is wearing a metal cap.
+** If Mario's forward velocity is more than 16 and he is not in contact with a physical wall/surface (i.e. OOB):
+*** A different sound is played, but Mario's yaw is not reflected. <!-- Some of these reflection calculations may be wrong -->
+** If Mario is in contact with a wall, his action is set to the [[Air Hit Wall|air hit wall]] action.
+** If Mario is not in contact with a wall (i.e. hitting OOB):
+*** Any positive vertical speed is capped to 0.
+*** If Mario's forward velocity is 38 or more, spawn particles and set his action to the [[Backward Air Knockback|backward air knockback]] action.
+*** If Mario's forward velocity is more than 8 but less than 38, set Mario's forward speed to -8 and set his action to the [[Soft Bonk|soft bonk]] action.
+** If Mario's forward velocity is 16 or less (initially, not after these other changes), set the forward velocity to 0.
+* '''Ledge Grabs'''
+** Mario's animation is set the idle ledge grab animation.
+** Mario enters the [[Ledge Grab|ledge grab]] action while dropping any held objects and no longer riding a shell.
+* '''Hangs'''
+** Mario's action is set to the [[Start Hanging|start hanging]] action.
+* '''Lava Wall Boosts'''
+** Mario's yaw is set perpendicular to the wall.
+** Mario's forward speed is capped to 24.
+** If Mario is not wearing a metal cap, he is hurt 12 (or 18 without his hat).
+** Mario plays the noise for being burned.
+** The camera preset is set to the area's default preset. <!-- This is overly simplified, perhaps best put on the camera page -->
+** Mario enters the [[Lava Boost|lava boost]] action while dropping any held objects and no longer riding a shell.
