How do you change the radius of a sphere in unity?

How do you change the radius of a sphere in unity?

Just change the localScale of the transform.

  1. var go = GameObject. CreatePrimitive(PrimitiveType. Sphere);
  2. go. transform. localScale = Vector3(scale, scale, scale);

What is Radius in unity?

A circle of radius unity is centered at thet origin. Two particles tart moving at the same time from the point (1, 0) and move around the circle in opposite direction. One of the particle moves anticlockwise with constant speed v and the other moves clockwise with constant speed 3v.

What is Sphere Collider in unity?

A standard Sphere Collider. Colliders work with Rigidbodies to bring physics in Unity to life. Whereas Rigidbodies allow objects to be controlled by physics, Colliders allow objects to collide with each other. Colliders must be added to objects independently of Rigidbodies.

What is Sphere cast?

Description. Casts a sphere along a ray and returns detailed information on what was hit. This is useful when a Raycast does not give enough precision, because you want to find out if an object of a specific size, such as a character, will be able to move somewhere without colliding with anything on the way.

How do you find the distance between two points in unity?

The distance between the two vectors is this vector’s length (or ‘magnitude’, a property which Unity handily provides for you), which you could manually calculate by using some trigonometry: Code (csharp):…

  1. float distance = Math. Sqrt(
  2. Pow(difference. x, 2f) +
  3. Pow(difference. y, 2f) +
  4. Pow(difference. z, 2f));

What is the difference between collider and trigger?

The physics engine simulates collisions using colliders. We can determine which objects will collide with each other, or how objects will behave under collisions using colliders. On the other hand, triggers are special setups of colliders. The purpose of triggers is to trigger events when more than one objects overlap.

What is Vector3 in Unity?

It is representation of 3D vectors and points, used to represent 3D positions,considering x,y & z axis.

Does collider need Rigidbody?

In Unity3D, you need rigidbodies on GameObjects that use colliders, as they use physics. You don’t need rigidbodies on static GameObjects because they don’t use physics, though you still need to have at least one in the calculation.

What is the radius of a sphere Collider?

Actually, the radius is five units. (.5 * 10) Whatever the radius is can be easily determined by multiplying the radius of the sphere collider that contains the object with the scale of the object. GargerathSunman, Jul 15, 2009 #4

How to find the radius of a sphere?

Whatever the radius is can be easily determined by multiplying the radius of the sphere collider that contains the object with the scale of the object. If the sphere has a collider, SphereCollider.radius should do the trick. Click to expand… i get the error “radius is not a member of UnityEngine.collider.”

What is a sphere-shaped primitive Collider?

A sphere-shaped primitive collider. See Also: BoxCollider, CapsuleCollider, PhysicMaterial, Rigidbody. The center of the sphere in the object’s local space. The radius of the sphere measured in the object’s local space. The articulation body the collider is attached to.

How to determine if a collider is enabled or disabled?

The world space bounding volume of the collider (Read Only). Contact offset value of this collider. Enabled Colliders will collide with other Colliders, disabled Colliders won’t.
