wish, action slider (undo/redo or chronological Preview/unpreview, hide/show SLIDER)

hi guys,

I am totally new to grasshopper, but I enjoy playing around with it and making different thing. Its kind of fun like playing with LEGO stuff.

So since I am a new player and the game is sometimes complicated, I wish there was a tool (specifically a slider) in grasshopper that when I open a complex file, I could slide back and forth between steps of actions which has been done to make the definition.

lets say we could imagine it as an Undo/Redo slider that starts from the first action till the end of composing the definition. it would be a grate tool for those who want to learn by playing around and see what happens step by step. it might be useful for others too to clearly see the steps and manage more complex systems.

and If undo and redo consumes a lot of processing power (I am not sure) I have another Idea.

The slider could preview or unpreview components and actions from step 1 to N.

but it should hide the components which are unpreviewed so I I can easily see the relation between definition and what happens in rhino view-port.

In other word, when I set the slider on the lets say step 7 , all the components which are made and used after that ( step 8 to N) should be hidden from the grasshopper definition so I could simultaneously follow the steps both in rhino view-port and grasshopper view-port.

thanks guys

cheers

Hi Vahid,

It doesn't take much computing to undo/redo specific actions. However it might cause a lot of computing because an undo/redo might expire some objects that take a long time to complete.

I designed the undo system specifically so that undo-data could be written to the ghx file, but I never came around to implementing this.

If I have some free time again (definitely not until 2011) I'll have another look at undo and how to make it more accessible and persistent.
