Creating new variables in for-loop?

rvs1977

Hi!

Is it possible to create new variables in a for-loop?

Now I have something like this, which works:


loop_length = 3

for i in 0..(loop_length-1)
  if (i == 0)
    @yv_group0 = Sketchup.active_model.entities.add_group
    @yv_face0 = @yv_group0.entities.add_face (@pts[1], @pts[2], @pts[3], @pts[4]) 
  end

  if (i == 1)
    @yv_group1 = Sketchup.active_model.entities.add_group
    @yv_face1 = @yv_group1.entities.add_face (@pts[5], @pts[6], @pts[7], @pts[8]) 
  end
 
  if (i == 2)
    @yv_group2 = Sketchup.active_model.entities.add_group
    @yv_face2 = @yv_group2.entities.add_face (@pts[9], @pts[10], @pts[11], @pts[12]) 
  end
end

I think it would be smarter if it was possible to create new variabels in the for-loop, like:


for i in 0..(loop_length-1)
  
    @yv_group_i = Sketchup.active_model.entities.add_group
    @yv_face_i  = @yv_group_i.entities.add_face (@pts[1+(i*4)], @pts[2+(i*4)], @pts[3+(i*4)], @pts[4+(i*4)]) 
end

As you can see, I would like to try to put the i on the variables.
Is that possible in some way??

Use an Array?

yes, I thought about but Im unsure how to do it.


face_array = Array.new(loop_length,Hash.new)

for i in 0..(loop_length-1)
    face_array[i][@yv_group_i] = Sketchup.active_model.entities.add_group
    face_array[i][@yv_face_i]  = @yv_group_i.entities.add_face (@pts[1+(i*4)], @pts[2+(i*4)], @pts[3+(i*4)], @pts[4+(i*4)]) 
end

Something like that...??

No.. in a similar way you that are using the @pts array.


@yv_group = []
@yv_face  = []
for i in 0..(loop_length-1)
    @yv_group[i] = Sketchup.active_model.entities.add_group()
    @yv_face[i]  = @yv_group[i].entities.add_face (@pts[1+(i*4)], @pts[2+(i*4)], @pts[3+(i*4)], @pts[4+(i*4)])
end

Ok thank you Dan. I will try that.
