another small function for you.
RotateToPointSlowly(e,x,z,speed)
similar to the core function RotateToPlayerSlowly(e,v) but allows you to specify the target co-ords yourself so you can face any direction or entity (via his co-ords)
video with example usage
to use it simply copy and paste the code into your global.lua (or to the outside of a script that will call the function) and use in the same way as any of the other functions
function RotateToPoint(e,x,z)
if g_Entity[e] ~= nil and x > 0 and z > 0 then
local destx = x - g_Entity[e]['x']
local destz = z - g_Entity[e]['z']
local angle = math.atan2(destx,destz)
angle = angle * (180.0 / math.pi)
if angle < 0 then
angle = 360 + angle
elseif angle > 360 then
angle = angle - 360
end
SetRotation(e,0,angle,0)
return angle
end
end
function RotateToPointSlowly(e,x,z,v)
if g_Entity[e] ~= nil and x > 0 and z > 0 then
if v == nil then
v = 1
end
local destx = x - g_Entity[e]['x']
local destz = z - g_Entity[e]['z']
local angleneeded = math.atan2(destx,destz)
angleneeded = angleneeded * (180.0 / math.pi)
if angleneeded < 0 then
angleneeded = 360 + angleneeded
elseif angleneeded > 360 then
angleneeded = angleneeded - 360
end
local current_angy = g_Entity[e]['angley']
while current_angy < 0 or current_angy > 360 do
if current_angy <= 0 then
current_angy = 360 + current_angy
elseif current_angy > 360 then
current_angy = current_angy - 360
end
end
local L = angleneeded - v
local R = angleneeded + v

L = L - 360
end

elseif R > 360 then
R = R - 360
end
--if not already facing the target direction (+/- the rotation speed)
if current_angy < L or current_angy > R then
--do it in 2 halfs so we can account for 0/360 wrap
if current_angy > 180 then
if angleneeded > current_angy - 180 and angleneeded < current_angy then
current_angy = current_angy - v
else
