I need to change PlayerPrefs using a C# script, but can't access Non-Static Function???

Hey guys, hopefully a simple answer will come from this, but, basically I made a game in javascript, but need to use a C# Bridge Script to associate my original scripts to the Facebook SDK C# Scripts. All I want to do is increase a PlayerPref value by a certain amount depending on what day it is.

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


public class FacebookTrigger : MonoBehaviour {
	public static int reward = 0;
	public static GameObject fbShareButton = GameObject.Find ("FacebookShareButton");
	// Use this for initialization
	void Start () {
		
	}
	public static void ResetButton() {
		PlayerPrefs.SetFloat("RetryTokens", PlayerPrefs.GetFloat("RetryTokens") + reward);
		reward = 0;
		//GameObject fbButton = GameObject.Find ("FacebookShareButton");
		Texture2D texd = (Texture2D)Resources.Load("Textures/ShareToFacebook", typeof(Texture2D));
		fbShareButton.renderer.material.mainTexture = texd;
	}
	void CheckAndSetDate () {
		if (System.DateTime.Now.DayOfYear == 1) {
			//NewYearsDay
			reward = 5;
		} else if (System.DateTime.Now.DayOfYear == 19) {
			//MartinLutherKingDay
			reward = 3;
		} else if (System.DateTime.Now.DayOfYear == 45) {

		} else if (System.DateTime.Now.DayOfYear == 47) {
			//PresidentsDay
			reward = 3;
		} else if (System.DateTime.Now.DayOfYear == 76) {

		} else if (System.DateTime.Now.DayOfYear == 91) {

		} else if (System.DateTime.Now.DayOfYear == 358) {
			//ChristmasEve
			reward = 3;
		} else if (System.DateTime.Now.DayOfYear == 359) {
			//CristmasDay
			reward = 5;
		} else if (System.DateTime.Now.DayOfYear == 365) {
			//NewyearsEve
			reward = 5;
		} else {
			reward = 1;
		}

		if (PlayerPrefs.GetFloat ("LastDay") < System.DateTime.Now.DayOfYear) {

My Issue is, I can not run anything from “ResetButton” function for some reason because it says it is Non-Static, but as you can see it IS a static function. So what is wrong?? I am very frustrated.

Your problem isn’t in ResetButton, PlayerPrefs methods are static, reward is static, texd is an instance and fbShareButton as a variable is static. But when you’re defining a field in c# you’re invoking a method and this isn’t allowed.

This line doesn’t work:

  public static GameObject fbShareButton = GameObject.Find ("FacebookShareButton");

You need to either set this static field at an appropriate time or access it as needed when using it.
