A hinge is a type of SketchyPhysics joint. The name being self-explanatory, it can be set to allow an object attached to it to rotate a certain amount of degrees, or all the way around. The hinge was one of the original joints introduced in SketchyPhysics 1. Despite this, it still remains a very useful joint, and can now be controllable.
- Minimum/Maximum: the lowest and highest amounts of degrees it can go. Set these to zero to have no limits.
- Acceleration: This value states how fast (if at all) the hinge should turn on its own.
- Damp: This states how hard it is for the hinge to turn. This means both by its own power and by someone trying to drag it. Negative values will mean that when touched, the hinge will not find resistance and will maintain its movement. The object will start to spin with increasing acceleration until it breaks. Nobody knows a use for this feature.
With the introduction of SketchyPhysics 2, the hinge, as well as the new joints, became controllable. In this sense, the hinge becomes a cross between a motor and a servo. By this, the hinge would act as a servo until it was set to either the maximum power or zero.
Click once to select the starting point of the cube.
Click again to set the width of the cube.
Click again to set the depth of the cube.
Click again to set the height of the cube.
Step 2: Creating the Hinge
Click on one of the cube's vertices to set the Hinge's origin, go up the edge on the blue axis and click on the vertices of the cube to set the hinge's orientation.
Step 3: Connecting the Box to the Hinge,
Click on the Hinge and then ctrl+click (WIN)/option + click (MAC) the box to connect them.
You're done! Once the Play button is pressed, the simulation will begin. You can hold down the mouse button and drag to make the box pivot around the hinge.
