Hi Momiji,
Here is an example showing how this can be done. It requires the latest version of Kangaroo.

thanks you!!

but an error happened

This appears to be exactly what I am looking for. BUT it fails with an error in the Solver component 1. Solution exception:Unable to cast object of type 'SphereCurveCollide' to type 'KangarooSolver.IGoal'.

Do you know why it is?

I think about a model moving circle with a mouse

To move circles with the mouse, include a 'Grab' component.

Then when it is running you can hold down the Alt key on your keyboard to drag points in the Rhino window with the left mouse button.

One possible cause could be that the version of Kangaroo is not the latest one (2.3.3), or possibly that the assembly reference location is set to a different, older copy of the .dll.

The file referenced by the C# component must be the same one loaded by Grasshopper. You can make sure of this by copy-pasting the folder location from File>Special Folders>Components Folder into the window that appears when you right click the C# component and choose Manage Assemblies>Add.

If that doesn't fix it, you could also try turning off the COFF loading option:

Kangaroo ver 233

and

The error continues even if I exclude a check

Which Rhino service release are you on?

It might also be worth trying deleting any extra copies of the KangarooSolver.dll file (from downloads folder etc), since for reasons I don't understand Windows still sometimes seems to load the wrong one (and even if they are loading different copies of exactly the same file, it won't work unless Grasshopper and the C# script are loading the same copy of the same file).

rhino5

I tried it, but the result did not change

Because C# does not seem to move with my PC, are there other methods?
