how to use getcomponent unity code example
Example 1: how to get component in unity c#
GetComponent<Rigidbody>(); //used to find component on character (rigid body can be changed)
GameObject.FindGameObjectWithTag("player"); //finds any game object in the scene with this tag
Example 2: unity get component
using UnityEngine;
public class TryGetComponentExample : MonoBehaviour
{
void Start()
{
// Since Unity 2019.2 you can use TryGetComponent to check
// if an object has a component, it will not allocate GC in
// the editor if the object doesn't have one.
if (TryGetComponent(out Rigidbody rigidFound))
{
// Deactivate rigidbody
rigidFound.enabled = false;
}
// For versions below 2019.2 you can do it this way:
// Create a variable
Rigidbody rigidFound = GetComponent<Rigidbody>();
// If the 'Rigidbody' exist in the gameobject
if(rigidFound != null)
{
// Deactivate rigidbody
rigidFound.enabled = false;
}
}
}
Example 3: unity gameobject.getcomponent
rb = GetComponent<Rigidbody>();
