I have an error on a C# script @username

I the line “GetComponents().addforce (Vector2.right * power);” there is an error saying
“Type ‘UnityEngine.Riidbody2D’ does not contain a definition for ‘addforce’and no extension method ’ addforce’ of type 'unityEngine.Rigidbody2D could not be found. Are you missing an assembly refernce?” How do I fix it? @username

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Player : MonoBehaviour {

	public int power = 500;
	public int jumpHeight = 100;
	public bool isFalling = false;

	// Use this for initialization
	void Start () 
	// Update is called once per frame
	void Update () 
		GetComponents<Rigidbody2D>().addforce (Vector2.right * power);


There is GetComponent(Singular) and GetComponents(Plural). When you use the plural version (GetComponents) the method/function returns an array of whatever type you specify you’re looking for. In this case RigidBody. It seems like you want the singular version which will return a single Rigidbody2D if available on the GameObject.


GetComponents().addforce (Vector2.right * power);


GetComponent().AddForce (Vector2.right * power);

Also @Davirtuoso was correct, you need to specify the methods with exact case.

I think the issue is your need to capitalise letters within ‘addforce’, like so:

GetComponent<Rigidbody2D>().AddForce (Vector2.right * power);

Captilisation matters a lot in c# and ‘addforce’ is considered a completely different method than ‘AddForce’. I hope this helps :slight_smile:
