Walljumps

How to do one#

Be in the air, touching a wall, falling, and press jump (a fresh press).

	Value
When	falling: vertical speed between −450 and 0 ups (not while rising, not when falling fast)
Which walls	near-vertical: wall normal \|z\| < 0.3; not slick, not sky, not a player
Touching	the wall must have been hit during the last move, and a probe 5 units into the wall must hit it; the probe ignores the lowest 34 units of your box
Up	a full jump: 270 ups (tired: 202.5, then −100)
Away from the wall	+200 ups along the wall's normal (tired: +100)
How many	`g_walljumps` per jump (default 3), reset when you land or grab a ladder
Cost	the same stamina as a jump

Touching only with your feet doesn't count: if the wall is only within the lowest 34 units of your box (like a step edge), the walljump fails, and **no more walljumps are allowed until you land** (the counter is set to 10).
The push adds to your speed; it doesn't replace it. A walljump at speed keeps the speed and turns you away from the wall.
The wall is registered during the move, so you need to actually bump into it, not just be near it.
Walljumps happen at the start of the air move, then air strafing continues in the same command.

Walljump climbs: two walls facing each other, or a corner, to climb up step by step (three per jump by default).
Rescue jumps: a wall next to a gap to save a short jump.
No-walljump walls: slick (icy) walls, to force a route.
The training tools include a walljump helper.
