Hanging by Ropes In the next,
I used a rope instead of chain. The model of rope is just a line go around swing chair.
Step 1: Select the seat object and apply Rigid Body collection to it.
Step 1: Select the seat object and apply Rigid Body collection to it.
Step 2: Select the Line and in the modifier panel, select reactor Rope modifier. You can also hit reactor Rope modifier
button on Reactor bar while the line is selected.
Step 3: In reactor Rope parameters, first go to Constraints rollout to define which vertices are fix and which ones need to
attach to the seat. In modifier stack active the Vertex sub-object. Then select the two topmost vertices and hit Fix Vertices
button. These vertices will not move during simulation.
Step 4: Now select the bottom vertices and hit Attach to Rigid Body button.
Step 5: After this, you need to define your rigid body object in scene. So select Attach to RigidBody from list. The new
rollout will appear with the same name of Attach to RigidBody. Click None button and then pick seat object from scene. Now
the bottom vertices that you selected them are attach to seat object.
Step 6: In properties rollout of reactor Rope modifier, you need to set parameters for your swing. The Mass of line object
will be set in here. You can define thickness of your rope in Thickness field. In the friction field you can specify how
smoothly the rope move relative to surfaces it's in contact with. Air Resistance is related to speed of simulation. It will
cause rope loses energy as it moves.
We have two rope types that for this project we need to use Constraint because it will not stretch rope.
Step 7: Our rope modifier will not work without Rope Collection. So Create a Rope Collection and add your line object to it.
Step 8: Final setting will be for seat object. Select it and increase its Mass. in this example I increase it to 5.
Step 9: Simulation is ready. You can hit Create Animation on the Reactor bar to create animation or choose Preview Animation
to watch realtime.
