How to change heading of a spawned unit via script ? (mist)

[winghunter]

Im using mist.cloneGroup to spawn new units and mist.teleportTopPoint to position them. But how can I change their heading / rotation ?

 

this doesnt work

    local unit = mist.getGroupData(grp).units[1]

    local newHeading = Heading + math.pi

    unit.heading = newHeading

Thanks

local newHeading = heading*math.pi/180

That should do the trick!

Thanks though i forgot to mention Heading is already in radians, as i get it form

    local Heading = mist.getHeading(player)

If you clone a group, only the datas of original group will be used. No way to change them.
If you want to change them, you need to spawn a new group with mist.dynAdd(), instead of cloning. (change groupName if you don't want to destroy previous group at spawn)
Code example to randomize headings at spawn of units of a ground group named 'test' :

local GPdata = mist.getGroupData('test')
for i = 1, #GPdata.units do
GPdata.units[i].heading = mist.utils.toRadian(mist.random(360))
end
mist.dynAdd(GPdata)

Thanks, i've updated to latest mist and tried this approach. It seems however that heading makes no difference to spawning air units, they will always face north even though their heading data says different.

heading is only for ground unit. Air spawned aircraft heading is defined by next wpt direction (same as in mission editor).

Ohhh thanks, this DCS api is full of easter eggs
