Here is a quick animation showing your code in action (no sound):

Hi,

The code runs while using the “Ruby Web Console” but when I try to make a jumper.rb out of it to put it on the plugins folder the following error shows;

Load Errors
Undefined method ‘transform!’ for nil:NilClassError Loading File
jumper.rb
undefined method ‘transform!’ for nil: NilClass

If I try to put the following;

def transform
$gc = Sketchup.active_model.selection[0]
vec = Geom;;Vector3d.new(0,0,1)
$t = Geom;;Transformation.new(vec)
$start = Time.now()

view = Sketchup.active_model().active_view()

view.animation = Jumper.new
end

The jumper.rb loads ok but when I press it no animations are triggered. Can someone please help me with this.

Thanks

Because the examples in this topic show very poor programming practice!

(1) The code is not namespace protected

(2) The code uses global variables that can conflict with other global variables.

(3) There is no selection checking that prevents an exception if the selection is empty.

(4) There is no entity Type checking to ensure that the selected entity(ies) can have the transform! method called upon them.

I'll see if I can cobble up a better example, perhaps I'll post it in a new [ Code ] topic (so it can be indexed with the Code Snippet indexer.)

Done!
