HOTSPOTS

Anonymous — Wed, 25 Mar 2009 09:40:11 GMT

Greetings All

I am new to GDL but enjoy it immensely.

The physical building is coming along well but I struggle with making the HOTSPOT do what I want them to do. Especially the rotate.

Can some one please explain the theory behind them?? How to make them work??

Regards

YellowToes:

You will be more likely to get an answer if you post what you are specifically trying to accomplish (images help), whether it is in 2D or 3D, and the code you have tried so far. Also, you should add your ArchiCAD version to your signature.

Yes GDL is quite addictive. Hotspots are really cool for adjusting parameter values graphically. For a 2D angle you could use a script like this:

!Hotspots to control an angle parameter angleParameter
!about a center xC, yC. The hotspot is positioned at radius R.
hotspot2 xC, yC, iHotspot + 1, angleParameter, 6
hotspot2 xC + R*cos(angleParameter), yC + R*sin(angleParameter),
iHotspot + 2, angleParameter, 5
hotspot2 xC + 1, yC, iHotspot + 3, angleParameter, 4
iHotspot = iHotspot + 3

You can also move a hotspot in 2 dimensions at once.

BTW hotspots are discussed in more detail in the GDL Handbook.
