Descripción

The Down State of MoveDirection. Assign functionality for moving in a downward direction.

Use the Down state for an easily identifiable way of moving a GameObject downwards (0 , -1 , 0). This is a state without any predefined functionality. Before using this state, you should define what your GameObject will do in code.

//Attach this script to a GameObject with a Rigidbody component. Press the "Move Down" button in Game view to see it in action.

using UnityEngine; using UnityEngine.EventSystems;

public class Example : MonoBehaviour { Vector3 m_StartPosition, m_StartForce; Rigidbody m_Rigidbody; //Use Enum for easy switching between direction states MoveDirection m_MoveDirection;

//Use these Vectors for moving Rigidbody components Vector3 m_ResetVector; Vector3 m_UpVector; const float speed = 10.0f;

void Start() { //You get the Rigidbody component attached to the GameObject m_Rigidbody = GetComponent<Rigidbody>(); //This starts with the Rigidbody not moving in any direction at all m_MoveDirection = MoveDirection.None;

//These are the GameObject’s starting position and Rigidbody position m_StartPosition = transform.position; m_StartForce = m_Rigidbody.transform.position;

//This Vector is set to 1 in the y axis (for moving upwards) m_UpVector = Vector3.up; //This Vector is zeroed out for when the Rigidbody should not move m_ResetVector = Vector3.zero; }

void Update() { //This switches the direction depending on button presses switch (m_MoveDirection) { //The starting state which resets the object case MoveDirection.None: //Reset to the starting position of the GameObject and Rigidbody transform.position = m_StartPosition; m_Rigidbody.transform.position = m_StartForce; //This resets the velocity of the Rigidbody m_Rigidbody.velocity = m_ResetVector; break;

//This is for moving down case MoveDirection.Down: //This moves the Rigidbody down m_Rigidbody.velocity = -m_UpVector * speed; break; } }

void OnGUI() { //Press the reset Button to switch to no mode if (GUI.Button(new Rect(100, 0, 150, 30), "Reset")) { //Switch to start/reset case m_MoveDirection = MoveDirection.None; }

//Press the Down button to switch the direction to down if (GUI.Button(new Rect(100, 90, 150, 30), "Move Down")) { //Switch to Down Direction m_MoveDirection = MoveDirection.Down; } } }
