Nice. Heheh... your expectations are so low.
Rope in Mythruna will not be a block type. It will be a special physics object.
How it will probably work if I can get it working at all....
You will select the rope as your build object. You will click somewhere and drag. The click sets the rope end and the drag stretches out some length of it. When you release the mouse, that's the length of the rope. If you've attached it to another object then they are now connected. If you left it dangling then it swings in the breeze... ready to be attached to something else or lengthened.
At least, that's the simplest interface mechanism I can think of.
Flipping it over into the other way, I could click the rope on the back of a chair and drag it out a little before releasing. Now I have a length of rope attached to the chair, just flopped down. If I switch off of the rope tool and back to a regular hand or glue or something then I can pick up the end of the rope and attach it to the ceiling. Now I have a chair swinging from the ceiling.
Note: the above will definitely NOT be in the next release but it's on the plan for how physics should work when finished. Well, unless I get a super tailwind and everything works smoothly... maybe ropes will get in. But I still have to write the rendering side of ropes so I sort of doubt it.
