![]() Basically, its mass and the way it responds to the physics environment. The physical body properties of the corresponding GameObject. Each Articulation Body component allows you to configure in one single place: To build a physics articulation in Unity, you must add an Articulation Body component to each GameObject that the articulation consists of. Not only would the joints look peculiar, but it would also be impossible to use them for simulating a real device, impeding efforts to model or prototype industrial designs. This might result in stuttery and unrealistic motion. More info See in Glossary might encounter unsolvable scenarios and leave certain constraints unsatisfied. If you try to use regular joints to model kinematic chains such as in a rag doll, robotic arm, or mechanism with several concurrent hinges, the physics engine A system that simulates aspects of physical systems so that objects can accelerate correctly and be affected by collisions, gravity and other forces. However, the overall resulting behavior is not the same in both cases, especially if you extend this principle to multiple physical bodies and joints. The joint properties depend on the type of Joint component that you add. One of the GameObjects also has a Joint component. The Articulation Body of the child GameObject holds the joint properties, where you can select the joint type. More info See in Glossary component, which defines physical body properties (among others). ![]() More info See in Glossary have an Articulation Body component, which defines physical body properties (among others).īoth GameObjects have a RigidBody A component that allows a GameObject to be affected by simulated gravity and other forces. A GameObject’s functionality is defined by the Components attached to it. Note: In more advanced scenarios, you can freely simulate kinematic loops.īoth GameObjects The fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. The GameObjects don’t necessarily have a hierarchical relationship. Note: The physics engine uses the Unity transform hierarchy to express the parent-child relationship. The GameObjects have a hierarchical relationship (parent-child). In the most basic scenario to get two physical bodies linked with a single joint, you can either build an articulation or use regular joints, as described in the following table. For example, they make it a lot easier than the regular Joints to simulate robotic arms and kinematic chains. The main purpose of physics articulations is to provide a realistic physics behavior for commercial and industrial non-gaming applications that involve joints A physics component allowing a dynamic connection between Rigidbody components, usually allowing some degree of movement such as a hinge. A physics articulation is a set of Articulation Bodies organized in a logical tree, in which each parent-child relationship reflects mutually constrained relative motion.
