The Item property of the Vector3 struct allows you to access or modify the individual components of the vector using an index. This property acts as an indexer for the Vector3 struct, enabling you to treat the vector as an array of three float values.
Use the Item property to access or set the x, y, or z components of a Vector3 instance by index. The index values are as follows:
0 for the x component1 for the y component2 for the z componentAttempting to access an index outside of this range will result in an IndexOutOfRangeException.
Vector3 vector = new Vector3(1.0f, 2.0f, 3.0f); // Accessing components using the Item property float x = vector[0]; // x = 1.0f float y = vector[1]; // y = 2.0f float z = vector[2]; // z = 3.0f // Modifying components using the Item property vector[0] = 4.0f; // vector is now (4.0f, 2.0f, 3.0f) vector[1] = 5.0f; // vector is now (4.0f, 5.0f, 3.0f) vector[2] = 6.0f; // vector is now (4.0f, 5.0f, 6.0f)
