Get position of Target

[Sharlikran]

I have been trying to figure out a better way to calculate the position of the target under the reticle in relation to the position of the player. I found a mod named RangeReticle that uses GetMapPlayerPosition('reticleover') and a rather complex bit of equations to determine the distance of the NPC from the player.

So I figured then GetMapPlayerPosition('player') is obviously the player. I would think GetMapPlayerPosition('reticleover') would return values for anything my reticle is over. For example, a harvest node, an NPC, a barrel, a Fishing hole, anything. However, it only seems to register and X and Y value when my reticle is over an NPC.

Is there anything else I can use to get the position of anything, not just an NPC, that is under my reticle?
