Descripción

Congela el movimiento a lo largo del eje-Y.

//This example shows how RigidbodyConstraints is used to freeze the position and rotation of a Rigidbody in the y axis at start-up.
//It also shows what happens when these constraints are removed, when you press the space key
//Attach this to a GameObject with a Rigidbody to see it in action

using UnityEngine;

public class Example : MonoBehaviour { Rigidbody m_Rigidbody; Vector3 m_YAxis;

void Start() { m_Rigidbody = GetComponent<Rigidbody>(); //This locks the RigidBody so that it does not move or rotate in the y axis (can be seen in Inspector). m_Rigidbody.constraints = RigidbodyConstraints.FreezePositionY | RigidbodyConstraints.FreezeRotationY; //Set up vector for moving the Rigidbody in the y axis m_YAxis = new Vector3(0, 5, 0); }

void Update() { //Press space to remove the constraints on the RigidBody if (Input.GetKeyDown(KeyCode.Space)) { //Remove all constraints m_Rigidbody.constraints = RigidbodyConstraints.None; }

//Press the up arrow key to move positively in the y axis if the constraints are removed if (Input.GetKeyDown(KeyCode.UpArrow)) { //If the constraints are removed, the Rigidbody moves along the y axis //If the constraints are there, no movement occurs m_Rigidbody.velocity = m_YAxis; }

//Press the down arrow key to move negatively in the y axis if the constraints are removed if (Input.GetKeyDown(KeyCode.DownArrow)) { m_Rigidbody.velocity = -m_YAxis; } } }
