Why is Unity collider not working?
2 Answers. Collider defined without RigidBody component is called Static Collider in Unity. If you do so, Unity assumes that the object will never move in the scene. On the other hand, if your object is an active one (moving), you need to attach RigidBody component in addition to Collider component.
How does Unity mesh collider work?
The Mesh Collider builds its collision representation from the Mesh attached to the GameObject, and reads the properties of the attached Transform to set its position and scale correctly. This means objects can pass through them from one direction, but collide with them from the other.
Why is my mesh Collider not working in Unity?
Surely you were adding the mesh collider to the object containing the visual mesh. In that case the component takes the visual mesh as collision mesh. Ryan_3D likes this. Mesh collider needs a mesh to check collisions against. No mesh, no collisions.
What do you need to know about mesh colliders?
Mesh Colliders An invisible shape that is used to handle physical collisions for an object. A collider doesn’t need to be exactly the same shape as the object’s mesh – a rough approximation is often more efficient and indistinguishable in gameplay. More info See in Glossary that are marked as Convex can collide with other Mesh Colliders.
How to apply a mesh Collider to a rigidbody component?
To apply a Mesh Collider to a Rigidbody component, tick the Convex checkbox. For a Mesh Collider to work properly, the Mesh must be read/write enabled in any of these circumstances: The Mesh Collider’s Transform has negative scaling (for example, (–1, 1, 1)) and the Mesh is convex.
How are gameobjects passed through a mesh Collider?
Faces in collision meshes are one-sided. This means GameObjects can pass through them from one direction, but collide with them from the other. Details about underlying algorithms and data structures used by mesh colliders can be found at PhysX documentation.
