How does each bodypart affect fatigue?

How much fatigue does each bodypart generate?

Each body part except MOVE and empty CARRY generate fatigue.

1 point per body part on roads, 2 on plain land, 10 on swamp. Each MOVE body part decreases fatigue points by 2 per tick. The creep cannot move when its fatigue is greater than zero.

If your interested in the code side, can view the movement intent.

thanks!

For clarification, CARRY parts generate fatigue if and only if there is at least one resource in that part. As an example, if a creep has 3 CARRY parts and is carrying 60 energy, two of the three CARRY parts would generate fatigue. (If you start using boosts, the calculations get a bit more complicated, but the principles are still the same.)
