NPC scripting command....

[TheFrozenFiend]

.............

playerspeed - To set the speed at which a player moves (default being 1). I know this can be done without the command, but it helps to reduce the size of large scripts (such as system npcs).
Then you could have npcs that only work if the player is going fast/slow enough.
eg.

NPC Code:

---

if(playerspeed>=1.5)

{message BOO!}

---

speed - Same as playerspeed but for npcs.
