The world's objects now meet the player through the original's own probe (worklog 171) in play, and what was left of the float stepping on the ground and in the jump is the original's integers. Played against the original (tests/hle.rs), three of the four scripts are now the same on every frame: the hub run into its wall (29 frames), level 11's Spike run (11) and level 18's slide along door 213, into the corner and the bump (70 frames, off by up to 28 before). The run and jump from the hub's start is the same for its first 27 frames, through the whole flight, to where the original meets toy 403 in the air.

• Objects as solids (boxes::solids, boxhit::Exact): every object's boxes are marked with the object as the original holds it: its integer position, its angles (placed ones from the quaternion, worklog 171; a door's swing added about y; a spinner's turn; a walker's heading; things and movers from their matrix, 0x8002114c), its model (radius for the bound and +0x86, boxes) and which box. Each frame they become the solids ground_move probes with (ground::Ground); the float boxes of those objects no longer stop the step on the ground, only the characters' do, and the air still uses them all.
• The thing stood on is carried between frames as its object and found again among the frame's solids (+0xf8, +0xfd).
• A slippery floor (flag 2) turns walls' ways off them.
• An object met head-on (+0xf4) is climbed only if its type says so (flag 64; message 29 if not) and is the bump's, its template's damage.
• The way (+0x178) is the body's matrix (0x80020d10 of the heading, MatrixNormal'd) applied to (0, 0, 4096), a little off unit (4103 long at 1430), not (sin, 0, cos) (0x8005c8d8); taken before the frame's turn.
• The slide scales the tangent to the old way's length (its floor square root, 0x8001f4ec, via 0x80076a74) before its VectorNormal; with the way's own length that is 171 a frame along the door, as the original, where 4096 gave 170.
• Into the body and back (0x80075f20, 0x80075ee8) are the MatrixNormal'd matrices and ApplyMatrixLV, not sin and cos products.
• The launch (0x80060f1c) is the way scaled to the jump's speed (its VectorNormal, 0x80076944) turned into the body, plus the rise; set at the animation's event, a frame before the port's first air step, so with that frame's heading (the run from the hub's start launches at (-1, -1000, 679), as the original).
