Define a const string with a variable name that stores a file name in which you print all the hierarchy of the game objects you want. GetComponent can be invoked three different ways. A script only defines a blueprint for a Component and so none of its code will be activated until an instance of the script is attached to a GameObject. SetActive Activates/Deactivates the GameObject, depending on the given true or false value. If you want to access another component (Mesh Renderer, Collider, Script,…) you need to use the GetComponent method to access the GameObject and tell Unity which component you are looking for. For performance reasons, it is recommended to not use this function every frame. Write a . However… If you're using multiple components of the same type on an object, it can be tricky to know which component is actually going to be retrieved. Unity will automatically set the correct reference at runtime. Answer (1 of 6): Looks like everyone else covered the FindGameObjects part. We can use the Transformation to access the children that have that GameObject, using the GetChild () method with parameter 0 of the Transform class, this results in the . Answer: As far as I know, there is no real simple way. At the same time, there are different Components in the Scene interacting with each other all the time. But on the line button = gameObject.GetComponent<Button>(); I get the following message: GetComponent requires that the requested component 'Button' derives from MonoBehaviour or Component or is an interface How can I access the "Button" component? We can also search and find a game object that matches a specific type. Add a Skills Component. The GameObject whose collider you are colliding with. The component based design of Unity means the script you're writing can be attached to any game object. GetComponentExample.cs. Add a script to that game object. It only finds active objects from your current scene. Getting many components Interaction between objects. using UnityEngine; public class Example : MonoBehaviour { void Start () { gameObject.GetComponent< Rigidbody > ().AddForce (0, 0, 1); } } Did you find this page useful?
