I am trying to detect where the cross-hair is pointing for Zombies that can only be killed by a head shot.
But my trig is very very weak (I cannot visualizes the angles/numbers in my mind the same way I can in geometry)
and I am not sure about one part of the script.

I think that

set Posz to ( Posz - ( player.getpos z * MyScale ) )

is not the right way to compensate for the players scale. But I am not sure how else to do it.
I do not need this kind of adjustment for the zombies as they will always be the same scale.

Scriptname aadpHeadShotRef targetFloat PoszFloat angxRef raceFloat Myscalebegin gamemode;;;This is for testing onlyset target to GetCrosshairRefif target != 0 if IsFormValid target != 1   set target to 0    elseif target.getdisabled == 1 || target.getdead == 1 || target.isactor == 0    set target to 0 endifendifif target != 0  set Posz to target.getpos z  set race to player.getrace  set Myscale to getracescale race  set Posz to ( Posz - ( player.getpos z * MyScale ) )  set Posz to Posz + 95  set angx to player.getangle x  set angx to angx * -1  set angx to ( ( tan angx ) * ( player.getdistance Target ) )  set angx to angx + 110  message"angle %.2f"angx          if  angx < ( Posz + 20 ) && angx >= Posz                messagebox"headshot"          endifendifend

This seems to work fine: the final dposZ value is the distance from the target feet to the aiming spot on the body. I suppose anything above 100 may be considered head.

Must adjust for other player positions, like sneaking or jumping.

And I think I read someone mentioning the camera stays in the same position, regardless of the race. You may want to check this.

:bowdown:

I had an idea to get the height difference between the player and the target using the OBSE bounding box commands and add that to the "set Posz to Posz + 95", but it was not working all that well yet. Probably because of the camera issue you mentioned? But your script will get me out of this math oubliette and on to finish the quest I am working on. Thank you so much!

(I heard on the Bethesda Podcast that this kind of math was not absolutely necessary to work for a game developer unless you are doing programming 3d engine type work, but I am finding that hard to believe. I need to find some on line Trig class I think.)
