I look for animated waves with buoyance build into sketchyphysics... that would be perfect, but I guess its hard to get.

rvs1977

Is there a oceanwavegeneratorplugin? In sketchyphysic there is buoyance, but no waves. I really
need it

Hi!

Is it possible to move edges or faces in a group through Ruby??....
So far a have only succeeded with the .pushpull method.

well thanks TIG!

I will study the script and hopefully get it

Hi all.

This one I have messed around with, for more than a week now, and is at the point to give up

My task is to make a tool that rotate a group in the direction of the mousepointer. It has turned out to be a difficult task because, it doesn't seems to be a way of keeping track of the group direction.

The problem using t= Geom::Transformation.rotation (point, Z_AXIS, delta_angle) and group.transform! t )is the delta_angle. Using this method it adds the angle to the previous angle.

This is what I have tried: (runable from the RCE)


class YV_tool
  def initialize
    @mod = Sketchup.active_model 
    @ent = @mod.entities    
    @state = 0

    inches = 1
    @mm = inches.to_mm

      
     @pts = []
     @pts[0] = [0,0,0]
     @pts[1] = [108/@mm,0,0]
     @pts[2] = [108/@mm,224/@mm,0]
     @pts[3] = [0,224/@mm,0]
  
  end # initialize

  def activate 
  end 

  def onMouseMove(flags, x, y, view) 
     ip = Sketchup;;InputPoint.new
     ip.pick view, x,y
     ip = ip.position 

     if (@state == 0) # Create Wall_group 
      @yv_group = @ent.add_group
      yv_face = @yv_group.entities.add_face @pts 
      yv_face.pushpull -10
      
      wall_edge = @yv_group.entities.add_line ([0,0,0], [1000/@mm,0,0])
      @yv_group_vector = wall_edge.line

As you can see, the group turn around, but not directly at the mousepointer.

I hope someone can come up with some ideas. Until then I will keep fighting...

Thanks in advance

How to attach a group to the mousepointer:

First, I think, you have to use the "Tool"-class, because in this class you have the onMouseMove-method.
(see also \plugins\examples\linetool.rb - it shows in detail how to use the tool-class)


class My_tool
  def initialize # a good place to put variables. Notice the "@". It means you can see the variable
                 # in the whole My_tool class. If no "@" it would only be visible inside the def.
    @mod = Sketchup.active_model 
    @ent = @mod.entities    
    @state = 0
         
     @pts = []
     @pts[0] = [0,0,0]
     @pts[1] = [10,0,0]
     @pts[2] = [10,20,0]
     @pts[3] = [0,20,0] 
     
  end 

  def activate  # activates the tool    
  end 

  def onMouseMove(flags, x, y, view) 
     ip = Sketchup;;InputPoint.new
     ip.pick view, x,y
     ip = ip.position 

     if (@state == 0) # Create Wall_group 
      @my_group = @ent.add_group
      my_face = @my_group.entities.add_face @pts 
      my_face.pushpull -10
      
      # ip is the input point from the mouse, converted to a 3d point 
      point = Geom;;Point3d.new ip 
      new_transform = Geom;;Transformation.new point  
      @my_group.transformation = new_transform
      @state = 1
    end
    if (@state == 1) # @my_group follow mousemove
      Sketchup.status_text = "@state = 1 ; Inputpoint; ", ip
      point = Geom;;Point3d.new ip 
      new_transform = Geom;;Transformation.new (point)
      @my_group.transformation =  new_transform
    end

    if (@state == 2) # onLMouseButton place @my_group in choosen position
      Sketchup.status_text = "@state = 2 ; Inputpoint; ", ip 
      point = Geom;;Point3d.new ip 
      new_transform = Geom;;Transformation.new (point)
      @my_group.transformation =  new_transform
      @ip1 = ip
      UI.messagebox "that should do it, Honolulu ;) - Press space to exit"
      @state = 3      
    end
     
  end # onMouseMove
  
  def onLButtonDown (flags, x, y, view)
    if (@state == 1)
      @state = 2
    end
  end # onLButtonDown
  
end # class My_tool
#------------------------------------
#------------------------------------
# Here you activate the defined tool in your program...

     mytool = My_tool.new 
     Sketchup.active_model.select_tool mytool

Great, thanks TIG!

Now it works

Hi all SUdudes...

I have a problem rotating a component instance around itself from a chosen inputpoint.
the component instance have been added, and then I want to rotate it:


......
ip.pick view, x, y
point = ip.position
vector = Geom;;Vector3d.new 0,0,1
angle = 2
t= Geom;;Transformation.rotation point, vector, angle
yv_instance.transformation = t

I expected it to rotate around the point with the vector and rotate it 2 radians. BUT instead of rotating it around itself, it rotates around the ip-point and 0,0,0... hmmm hope you understand.

the question is: How do I rotate a component around itself???

tnx in advance

rvs1977

looks great!

I discovered a strange behavior with my (danish)keyboard. When I want to
make brackets [ ], it opens a small textarea inside the console.
The textareabox appears when I push the AltGr key. When I enter numbers
and press Enter, it submits it at the top op the console???

anyone seen that too?

rvs1977

Thanks to both of you.
It pretty much answer all my questions for now!

btw, SU and ruby combined makes me breathless. I got a tons of ideas, but only
beginning to learn.

Hi all

as a beginner, I have a simple question I guess

Im looking how to "intialize" entities into a component at startup.
As far as I know its possible to use something like componetdefintions??

For instance I want to make a reusable box I can use again and again.
I dont want it to load it from a file.

tnx in advance

I get it... but I was looking for "something better"

Hi!

In SkPh, is it possible to make waving water?
For instance, if I want to make a sailing ship in the waves...

Thx in advance
