I added one more function for VIObject to be able to delete self when object is destroyed. Since I didn't find a corresponding function for this. The function I added does the following:
var _ind = ds_list_find_index(systemReference.objectList, self);
ds_list_delete(systemReference.objectList, _ind);
Did I do it right? Everything works fine for me!
If it works, it works :D There is still some functionality one could add like the delete function you've added, or interaction between different ropes/softbodies. However, I won't be able to work on this project for a longer time again now so feel free to add what you need :)
That being said, I plan to upload the project to github the next couple of days, so if you want you could also contribute there.
