New API doc - typos and questions

ToolObservers? How are they related to onClose and onOpen?

I meant to say, InstanceObservers.

In any case, they fire fine for me.

Hmm... When I tried to implement it in my plugin the onClose never fired. I also tried Jim's observer test script: http://sketchuptips.blogspot.com/2008/03/plugin-oberver-tests.html - and that never fired either. Could you post a working sample where onClose fires? (The onOpen always works though.)

Give this a go... Could be that we're seeing a sneaky bug...

class MyInstanceObserver < Sketchup;;InstanceObserver
   def onOpen(instance)
     UI.messagebox("onOpen; " + instance.to_s)
   end

   def onClose(instance)
     UI.messagebox("onClose; " + instance.to_s)
   end
end

model = Sketchup.active_model
model.definitions[0].instances[0].add_observer(MyInstanceObserver.new)

Nopes. Doesn't work.

Jim

Works for me...

Scott just found out that it works if the script loads when SU loads. But if you put it a subfolder for instance, and then manually load it, it won't work.
Jim's Observer tests never fire the event in SU7. However, in SU6 it works fine.

Jim

Just wondering if you have Dynamic Components on, and what happens if you turn them off?

Well I'll be! After disabling DCs the onClose even works!

btw, the DefinitionObserver works in SU6. But not SU7. Noticed that when I tested this observer in SU6.

Self note: need to add an explanation of how add_face works in relation to which "side" of the face is inside vs. outside, and document the exception where faces drawn at z=0 are always drawn with inside facing upward.

From Didier's post:

Need to add an FAQ for getting to installation directory of SU, for folks trying to build installers (and find out a mac equivalent.)

BoundingBox.valid?

text says

status
    true if the bounding box is valid (not empty), false if it is not valid (empty)

but the code example has it exactly the opposite:

 bbox = Sketchup.active_model.bounds
 status = bbox.valid?
 if (status)
   # If true, bounding box is empty.
 else
   # If false, bounding box contains entities.
 end

The introduction to RenderingOptions class states:

@unknownuser said:

The majority of the rendering information returned exists in the Model Info > Display section of SketchUp.

There is no longer a Model Info > Distplay section of SketchUp. I suppose it should say its in the styles inspector or something like that.

http://code.google.com/apis/sketchup/docs/ourdoc/renderingoptions.html#introduction

Also, the API doesn't list these:

DisplayQueWidth
DisplayDims
DisplaySketchAxes
DisplayText
DisplayWatermarks
DrawDepthQue
DrawLineEnds
DrawProfilesOnly
DrawUnderground
EdgeType
FogEndDist*- listed as FogEnd in the API*
FogStartDist - listed as FogStart in the API
HideConstructionGeometry
LineEndWidth
LockedColor
SectionTransparencyMode
ShowViewName

And the API lists these which don't appear to be valid:
DisplayFogEdges
FogDensity
FogEnd - appears to actually be FogEndDist
FogStart*- appears to actually be FogStartDist*
FogType

I tried to be thorough, but perhaps I missed something. It might not be bad to double check my work

http://code.google.com/apis/sketchup/docs/ourdoc/tool.html#onReturn

the onReturn method is showing an example for onMouseLeave

http://code.google.com/apis/sketchup/docs/ourdoc/view.html#zoom_extents

Does not give an example of view.zoom_extents. It gives an example of view.zoom

ModelObserver.onExplode
http://code.google.com/apis/sketchup/docs/ourdoc/modelobserver.html#onExplode

@unknownuser said:

The onExplode method is invoked whenever a component anywhere in this model is exploded. This is an easier way to watch explode events vs. attaching an InstanceObserver to every instance in the model.

The docs in InstanceObserver http://code.google.com/apis/sketchup/docs/ourdoc/instanceobserver.html doesn't mention any explode event. All though, I imagine there used to be. ModelObserver.onExplode is new to SU7, and I'm sure there was an explode related event in SU6. But it's MIA atm.

Face.position_material
http://code.google.com/intl/nb/apis/sketchup/docs/ourdoc/face.html#position_material

Doesn't explain the difference between using 2,4,6 or 8 points.

Vector3d.samedirection?

@unknownuser said:

vector = Geom::Vector3d.new 0,0,1
vector2 = Geom::Vector3d.new 0,1,0
status = vector.sime_direction? vector2

Face.mesh
http://code.google.com/intl/nb/apis/sketchup/docs/ourdoc/face.html#mesh

@unknownuser said:

The mesh method creates a polygon mesh that represents the face. See the PolygonMesh class for more information.

Valid flags are:
* 0: Include PolygonMeshPoints,
* 1: Include PolygonMeshUVQFront,
* 2: Include PolygonMeshUVQBack,
* 4: Include PolygonMeshNormals.
Add these numbers together to combine flags. A value of 5 will include all flags, for example.

No example given.

UVHelper.get_front_UVQ UVHelper.get_back_UVQ
http://code.google.com/intl/nb/apis/sketchup/docs/ourdoc/uvhelper.html

@unknownuser said:

a Point3d containing the UV coordinates where the X value is the U value, the Y value is the V value and the Z value is a Q value (which is not used).

I does appear that the Q value is used. At least when you have a warped texture. (Texture mapped not as a rectangle or parallelogram.) See this thread for further details and sample data: http://www.sketchucation.com/forums/scf/viewtopic.php?f=180&t=19041

thomthom

And I'd also wish there was info about projected textures.

http://code.google.com/apis/sketchup/docs/ourdoc/entities.html#add_curve

the .add_curve method says it returns a Curve object. It does not. It returns an array of edges.

I would prefer that it returned the curve object. But that might break the backward compatibility if other scripts have had to work around this?
