I'm having some problems getting my proggie working correctly, but cant yet put it down to a certain bit of code. But.. I think it could be this..

I'm passing an object handle into a function that calculates the correct height, and positions it.

Function fixentity_height#(ent)
Pick=LinePick(EntityX#(ent),EntityY#(ent)+20,EntityZ#(ent),0,-30,0)
PositionEntity ent,EntityX#(ent),PickedY#(),EntityZ#(ent)
End Function


Works fine if its a parent object I'm passing to it, but I'm getting some strange results when I pass a child object.

(and I've defined a global variable when the object was first loaded)

Can anyone help explain why ?

This is just a guess, based on a simple assumption:
I am purely guessing it's because the entities are Children, so the problem must be the conversion between Local/Global space (maybe)

try the following and see if it makes much difference...



The " ,1 "in the EnitityX,Y and Z commands guarantees Global Coords.

Make sure you change the PositionEntity line as well (also add a final ,1 to the end of the PositionEntity command!
