If Projectedz()=0 then Projectedx() = 0. I will have

This seems to suggest to me that the last 'picked' point is, by the time you do ProjectedX() actually offscreen.
What are you picking with? Camera? Mouse coords?

Hi ....

hir isent 1 Code snipe:

CameraProject cam,EntityX(schiff\hud,1),EntityY(schiff\hud,1),EntityZ(schiff\hud,1)
If ProjectedZ()>0.0 ; gibt komischerweise 0.2 zurück
If viw>0
HideEntity schiff\rad
Else
rx#=((sx/2-ProjectedX())/-(sx/1.0))
ry#=((sy/2-ProjectedY())/-(sy/.75))
If rx<-.47 Then rx=-.47
If rx>.47 Then rx=.47
If ry<-.37 Then ry=-.37
If ry>.37 Then ry=.37
ShowEntity schiff\rad
EntityColor schiff\rad,0,$ff,0
PositionEntity schiff\rad,rx,-ry,1
EndIf
Else

THX

I don't understand your question. Specifically, what does this line mean?

I'm not sure what you're getting at, but ProjectedZ returns either 0 or the near clipping plane depending on if the projected entity is withing the near and far clipping planes.
