Move Speed
Move Speed is a stat: Speed of movement in cells per second (c/s). Its default value is 3. A default Human has a base movement speed of 4.6 c/s.
Factors

Offsets
First of all the following offsets are applied to the Move Speed Base value.
- Traits
- Jogger: +0.4 c/s
- Fast walker: +0.2 c/s
- Slowpoke: −0.2 c/s
- Gear
- Minigun: −0.25 c/s
- Plate armor: −0.8 c/s
- Flak vest: −0.12 c/s
- Flak pants: −0.12 c/s
- Flak jacket: −0.12 c/s
- Marine armor: −0.4 c/s
- Grenadier armor: −0.4 c/s
- Prestige marine armor: −0.4 c/s
- Cataphract armor: −0.8 c/s
- Phoenix armor: −0.8 c/s
- Prestige cataphract armor: −0.8 c/s
- Burka: −0.4 c/s
- Artificial body parts
- Ghoul barbs: −0.25 c/s
- Ghoul plating: −0.7 c/s
- Metalblood heart: −0.2 c/s
- Hediffs
- Ghoul frenzy: +4 c/s
- Genes
- Very fast runner: +0.4 c/s
- Fast runner: +0.2 c/s
- Slow runner: −0.2 c/s
- Naked speed:
- Unclothed: +0.1 c/s
- Clothed: −0.2 c/s
Factors
The following factors are applied after the Offsets.
- Moving capacity: 100% importance, no allowed defect. No Max (effectively 311%).
- Go frenzy (inspiration): ×140%
- Light: scaling linearly from ×80% at 0% light to ×100% at 30% light. Pawns that are Blind, have the Lighting: Darklight preferred precept, or have the Dark vision gene are unaffected by this factor.
External factors
Weather
- Rain and Foggy rain: ×90%
- Rainy thunderstorm and Hard snow: ×80%
Path cost
Floors, buildings, items and plants add path cost. Where each path cost adds about 7.7% to the time it would take the pawn to traverse this tile unhindered. The move speed factor can therefore be calculated like this:
move speed factor = 1 / (1 + path cost * 0.077)
For terrain, flooring and things with a path cost of 20 or below, a pawn is slowed down every time they enter a tile with that thing. For things with a path cost of 25 or above continuing walking on a thing with a path cost of 25 or higher doesn't slow the pawn down again (even if it gets higher).[Fact check] Walking over an item on a workbench slows the pawn down again, items on shelves have no additional effect, however.
Below is a selection of some common values. Minified things have a path cost of 14.
You can see the path cost of every thing here.
Flooring and terrain
For flooring and terrain see the full list below. Note that pawns are slowed down continuously by terrain, but things on top of it with a path cost equal or below it, don't slow the pawn additionally.
Floor Move Speed Factor Burned floor 0.93 Flesh 0.87 Fungal gravel 0.87 Gray surface 0.87 Rough stone 0.87 Rough-hewn stone 0.93 Straw matting 0.93
- Other terrain
- Chest-deep moving water: ×24%
- Marsh, Shallow ocean water, Shallow water and Shallow moving water: ×30%
- Marshy soil, Mud, Soft sand and Ice: ×48%
- Sand: ×76%
- Lichen-covered soil: ×81%
- Soil, Stony soil, Rich soil: ×87%
- Snow
- Thin: ×76%
- Medium: ×62%
- Thick: ×52%
Example
This section is suggested to be rewritten. Reason: Genes mentioned in stub note above. You can help the RimWorld Wiki by improving it. |
Moving speed of a particular pawn can be calculated using the following formula:
Move speed = (Base value + Offsets) × Factors × External factors
Let us calculate how fast a human could possibly go. It would have the following values:
- Base value: 4.6 c/s
- Offsets:
- Jogger trait: +0.4 c/s
- Very fast runner gene : +0.4 c/s
- Naked speed gene unclothed : +0.1 c/s
- Factors:
- External factor: ×100%
Move speed = (4.6 c/s + 0.4 c/s + 0.4 c/s + 0.1 c/s) × (4.23 × 1.4) × 1 = 32.57 c/s
- ↑ Be aware that it is not possible to achieve this speed in a short time since the three hard drugs required to take have a 100% chance of causing a Minor Overdose and reducing Consciousness by 50%. 0.042 Overdose Severity is lost every hour so you would need to wait 1 to 6-hours between drugs.
Notes
Offsets, such as the speed decrease from gear or traits, occurs before multiplicative factors such as Moving. So while a normal human moves at 4.6c/s, and a human in a flak vest moves at 4.48c/s for a difference of -0.12c/s, a pawn with 2 archotech legs would move at 6.9c/s while the same pawn in a flak vest would move at 6.72c/s for a difference of -0.18c/s. Similarly, jogger-traited human moves at 5.00c/s for a difference of 0.40/s compared to baseline, but a pawn with 2 archotech legs would move at 6.9c/s while the same pawn as a jogger would move at 7.50c/s for a difference of +0.60c/s.
