NPC Yaw Rotation

[Xinux]

Here is the basic Yaw value if you want to set a NPC's heading.

Code: Select all

East  -> 0
south -> 16384
west  -> 32768
North -> 49152

Max value is 65536 which is basically East since it resets to 0

Here is a breakdown to help explain it.

Code: Select all

Unreal Units	Degrees	Radians * π	Steps per circle
1024	        5.625	  1/32	       64 (default step size of the rotation grid)
2730	        15	     1/12	       24 (not quite round, it's actually 2730.6666... )
8192	        45	     1/4	        8
16384	       90	     1/2	        4
24576	       135	    3/4	        2.66...
32768	       180	    1	          2
65536	       360	    2	          1 - full circle

You can also do this do a /loc ingame and take your rotation and multiple it by 91.02

Example

180 x 91.02 = 16384

16384 will be the yaw value that i enter into the DBE.

For my own notes, since I'm a dumbass and won't remember this when I need it later, if you have a negative rotation:
Rot + 180 then multiply it by 91.02.

If this is useful for anyone, please feel free to use it - I created a simple function to return an NPC to their original heading after x seconds.

Add these 2 lines into your scripts:

require "Spawns/Generic/spawn_functions"

and

Return_Rotation(Npc, pause)


That will return the NPC to its original rotation (pitch, yaw, roll) that's in the db after however many seconds you set for pause. I'm starting to add that into the hailed() function which also has facetarget() in it, so when you hail the NPC it faces you, then returns to where it started x seconds later.

[Moldew]

OK, added a better one.

Face_and_Return(Npc, Player, pause)

That will make the NPC face the player and return after x seconds. Put that into your hailed() and your good to go.

Oh, nice. Thanks Moldew. But man, that's a lot of NPCs that need to be edited.

[Moldew]

Yeah...

Some of mine don't turn at all, some do. I guess something to keep in mind moving forward. Or maybe a nice project for a new content dev! That way he/she can learn the ropes from looking through various scripts!
