I'm just curious about the Rope enemies. When they align with Link's position, they charge at him with an increased step speed. I can think of 3 ways that it may be done in code, and I'm wondering which way is the correct one:

1. The speed is an addition to the standard step speed; i.e. Step + X.
2. The speed is a multiple of the standard step speed; i.e. Step * X,
3. The speed is a constant value used regardless of Step speed; i.e. just set it to X.

Which one is correct?
