Custom - You may attach any point mass to any other point mass.ġ. Internal - These springs are generated by triangulating the body and Connect the PointMasses to each-other on the inside of the body.ģ. Edge - These springs wrap around the perimeter of the bodyĢ. There are three types of springs available to to each body:ġ. *if your simulation starts exploding, start by reducing damping values. At this length, no forces will be applied to either end of the spring. Length - The at-rest length of the spring. Damping* - How much the spring resists change in length.ģ. Springs may be modified via the Spring subcomponenet editor.Ģ. Springs and spring forces are used extensively in JelloPhysics. In Scene view, click and drag purple PointMass square out of the body (PolygonCollider2D). Click "Del" button next to the internal point mass to be removed(This button is only available for Internal PointMasses).ģ.
Expand the Internal PointMasses fold-out.Ĥ. Your point mass will be added and visible as a purple square and can be dragged around and edited in the inspector.ģ. In Scene view, move mouse to any point inside of the body (within the PolygonCollider2D) and click.
Click the now visible "Add Internal PointMass" button.Ĥ. Select the Point Mass subcomponent editor.ģ. Perform position correction once per fixed-update, moving the point mass back inside of the body.Ģ. Internal point masses have the potential to be pushed outside of the perimeter of the body by spring forces so the force internal option will force the simulation to Note that an internal PointMass must have some sort of spring forces (shape matching or springs) acting on them or else they will fall with gravity forever. These PointMasses are considerably useful for adding extra support to an area of a body via springs and are also very useful in breaking long-narrow mesh triangles. Internal PointMasses allow you to have points inside the body that are not considered for collision detection or the shape of the PolygonCollider2D. Select the appropriate sub component from the popup at the bottom of the inspector. In order to keep the editor interface from being to long, JelloBody sub-components (point masses, springs, attach points, joints) can be modified one type at a time. The body's base shape is based on the collider at the start of simulation.ĭuring runtime however, the body's PointMass positions will determine the PolygonCollider2D positions, so it is best to change the body's base shape (JelloBody.Shape). To change the shape of your body while in the editor, simply modify the PolygonCollider2D attached to the body's GameObject. Once a body component is attached you may select a new body type from the bottom of the JelloBody inspector, applying to complete the change. JelloPressureBody - This class inherits from JelloSpringBody so will keep shape via spring forces but also simulates gas on the interior of the body, pressurizing it.Ĭreating a body is as simple as adding any component to a GameObject.Įither drag one of the body classes from the project view onto a GameObject (inspector view) or click "Add Component" in the GameObject inspector and select any of the body classes. JelloSpringBody - This class inherits from JelloBody and keeps its shape via spring forces.ģ. Derive from this body to create your own implementations.Ģ. JelloBody - The base class for all other bodies and only accepts external forces (collisions and gravity).
The three body types that are provided by this system are:ġ. JelloPhysics is a tool to create and simulate soft bodies in line with Unity's 2D physics system. ******The original JellyPhysics library may be downloaded at.
