Ok, I finally figured it out. The o'clock can't be based on the bearing from player to target alone, it also needs the players bearing, because its' the delta of those two. It is probably possible to refactor this, but here is the code I got it to work with:
Startup (after MIST.lua load) - do script:
function getHeading(unitpos)
local hdg = math.atan2(unitpos.x.z, unitpos.x.x)
if hdg < 0 then
hdg = hdg + 2 * math.pi
end
hdg = math.floor(hdg / math.pi * 180)
return hdg
end
function getClockBearing(player_point, target_point, player_heading)
local angle = math.deg(mist.utils.getHeadingPoints(player_point, target_point))
if player_heading > angle then
angle = 360 + angle - player_heading
else
angle = math.abs(player_heading - angle )
end
local oClock = math.floor(angle / 30 + 0.5)
if oClock <= 0 then
oClock = 12
end
return oClock
end
player = Unit.getByName("player-1")
target = Unit.getByName("lead-1")
Then the repetetive task, do script:
local heading = getHeading(player:getPosition())
local clock_bearing = getClockBearing(player:getPoint(), target:getPoint(), heading)
