Bounds.Intersects

Description

Does another bounding box intersect with this bounding box?

Check if the bounding box comes into contact with another bounding box. This returns a Boolean that is set to true if there is an intersection between bounds. Two bounds are intersecting if there is at least one point which is contained by both bounds.

//Attach this script to an empty GameObject. Create 2 more GameObjects and attach a Collider component on each. Choose these as the "My Object" and "New Object" in the Inspector.
//This script allows you to move your main GameObject left to right. If it intersects with the other, it outputs the message to the Console.

        if (m_MyObject != null)
            m_Collider = m_MyObject.GetComponent<Collider>();

        //Check that the second GameObject exists in the Inspector and fetch the Collider

            m_Collider2 = m_NewObject.GetComponent<Collider>();
