Rotating Dynamic Hotspot Help?

[JGoode]

Hi,
I have tried using the script given in the gdl guide but I can't seem to get it to work. Does anyone know how to make it work correctly?

! --------------------------------------------------------------------------------
! Center
! --------------------------------------------------------------------------------
hotspot2 0, 0, unID, ang, 6     : unID = unID + 1

! --------------------------------------------------------------------------------
! Base
! --------------------------------------------------------------------------------
hotspot2 r, 0, unID, ang, 4     : unID = unID + 1

! --------------------------------------------------------------------------------
! Moving
! --------------------------------------------------------------------------------
hotspot2 r * COS(ang), r * SIN(ang), unID, ang, 5     : unID = unID + 1

I have created parameters for ang and R.

I really just need some explanation of the code. For some reason the angle increases when going anti-clockwise instead of clockwise. In 2D. The base does isn't position above at what should be 0 degrees.

If I look at page 197 of the GDL Reference Guide in ArchiCAD 20, the diagram is quite clearly going counter clockwise, perhaps this is intended?

Edit: this is also how the angles work in ArchiCAD when drafting.

Seems very strange. I was having some other issues when changing the centre point of the rotation so I have had to keep it at 0, 0 which is inconvenient. Thanks for the help.

All of the hotspots need to have the same base co-ordinates.
An easy way to do this is leave the base at 0,0 but put an ADD before the hotspots
i.e.

ADD x, y
! Center 
! -------------------------------------------------------------------------------- 
hotspot2 0, 0, unID, ang, 6     : unID = unID + 1 

! -------------------------------------------------------------------------------- 
! Base 
! -------------------------------------------------------------------------------- 
hotspot2 r, 0, unID, ang, 4     : unID = unID + 1 

! -------------------------------------------------------------------------------- 
! Moving 
! -------------------------------------------------------------------------------- 
hotspot2 r * COS(ang), r * SIN(ang), unID, ang, 5     : unID = unID + 1

DEL 1

or

 ! Center 
! -------------------------------------------------------------------------------- 
hotspot2 x+0, y+0, unID, ang, 6     : unID = unID + 1 

! -------------------------------------------------------------------------------- 
! Base 
! -------------------------------------------------------------------------------- 
hotspot2 x+r, y+0, unID, ang, 4     : unID = unID + 1 

! -------------------------------------------------------------------------------- 
! Moving 
! -------------------------------------------------------------------------------- 
hotspot2 x+r * COS(ang), y+r * SIN(ang), unID, ang, 5     : unID = unID + 1

Adding a flag value of 512 to the centre hotspot (type 6) will make it rotate in the opposite direction.

Thanks very much. This is very useful.
