Here's what I'm using. ZoomFactor is either 1 or 5. When it's 5, the hit point moves on the screen.
I never move the camera, only angle it. CPV is of type Vector.
Type Vector
Field x#, y#, z#
End Type
Function SetCPV() ; CameraPointingVector
Local length#, temp#
CPV\y# = -Sin(Altitude)
temp# = Cos(Altitude)
CPV\x# = -Sin(Azimuth) * temp#
CPV\z# = Cos(Azimuth) * temp#
length# = Sqr(CPV\x# * CPV\x# + CPV\y# * CPV\y# + CPV\z# * CPV\z#)
CPV\x# = CPV\x# / length
CPV\y# = CPV\y# / length
CPV\z# = CPV\z# / length
AlignToVector(theCamera, 0, 1, 0, 2)
AlignToVector(theCamera, CPV\x#, CPV\y#, CPV\z#, 3)
End Function
;end SetCPV
Function SetZoomFactor(inzoom#)
ZoomFactor# = inzoom
CameraZoom(theCamera, ZoomFactor#)
If inzoom = 1 Then
ASDActivateSprite(SightSprite, 0)
ASDActivateSprite(ScopeSprite, 0)
Else
ASDActivateSprite(SightSprite, 1)
ASDActivateSprite(ScopeSprite, 1)
Azimuth# = Azimuth# + Rnd(-2, 2)
Altitude# = Altitude# + Rnd(-2, 2)
EndIf
End Function
;end SetZoomFactor
Function Shoot()
Local tempx#, tempy#, tempz#
tempx# = EntityX(theCamera)
tempy# = EntityY(theCamera)
tempz# = EntityZ(theCamera)
LinePick(tempx#, tempy#, tempz#, tempx# + CPV\x# * 50000, tempy# + CPV\y# * 50000, tempz# + CPV\z# * 50000)
AddSmak(PickedX(), PickedY(), PickedZ())
PlaySound(ShotSound)
BeforeZoomOutFramesLeft = BeforeZoomOutDelay
ReloadFramesLeft = ReloadDelay
End Function
;end Shoot
Function AddSmak(inx#, iny#, inz#)
PositionEntity(Smaks(SmakPointer)\Entity, inx#, iny#, inz#)
ShowEntity(Smaks(SmakPointer)\Entity)
Smaks(SmakPointer)\FramesLeft = 45
Smaks(SmakPointer)\Active = 1
SmakPointer = SmakPointer + 1
If SmakPointer > NumSmaks Then SmakPointer = 1
End Function
;end AddSmak
