Ok I have a block with a gui and I was wondering how to make it save the data heres the code

 

package com.mcpixelplex.Gui;

import java.awt.Font;
import java.awt.font.FontRenderContext;
import java.awt.geom.AffineTransform;
import java.text.SimpleDateFormat;
import java.util.Date;

import org.lwjgl.opengl.GL11;

import com.mcpixelplex.items.bStick;
import com.mcpixelplex.lib.RefStrings;

import net.minecraft.client.Minecraft;
import net.minecraft.client.gui.GuiButton;
import net.minecraft.client.gui.GuiScreen;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.util.ChatComponentText;
import net.minecraft.util.ResourceLocation;

public class InfoGui extends GuiScreen {

Minecraft mc = Minecraft.getMinecraft();

GuiButton testButton;

EntityPlayer player = mc.thePlayer;


String title = "Info Block";
AffineTransform affinetransform = new AffineTransform();     
FontRenderContext frc = new FontRenderContext(affinetransform,true,true); 
Font font = new Font("Tahoma", Font.PLAIN, 12);
int titleWidth = (int)(font.getStringBounds(title, frc).getWidth());
int titleheight = (int)(font.getStringBounds(title, frc).getHeight());

int tabWidth = 61 + 10;

int titleXPos = (tabWidth - titleWidth) / 2;


SimpleDateFormat sdf = new SimpleDateFormat("h:mm a");
String time = sdf.format(new Date());

String format = "24 Hour Period";
boolean timeFormat;

public final int xSizeOfTexture = 256;
public final int ySizeOfTexture = 156;


public final int xSizeOfInterier = 226;
public final int ySizeOfInterier = 113;

public final int xSizeOfSideGap = 11;
public final int ySizeOfSideGap = 115;

public final int xSizeOfTopGap = 228;
public final int ySizeOfTopGap = 11;
public final int xSizeOfBottomGap = xSizeOfTopGap;
public final int ySizeOfBottomGap = ySizeOfTopGap;


@Override
public void drawScreen(int x, int y, float f){

	int xPos = (this.width - xSizeOfTexture) / 2;
	int yPos = (this.height - ySizeOfTexture) / 2;

	int levelPosX = (xSizeOfTexture) / 2;
	int levelPosY = (ySizeOfTexture) / 2;

	int bottom = (ySizeOfTexture - 20 - 2);

	GL11.glColor4f(1F, 1F, 1F, 1F);
	mc.renderEngine.bindTexture(new ResourceLocation(RefStrings.MODID, "/textures/gui/background2.png"));

	drawDefaultBackground();

	drawTexturedModalRect(xPos, yPos, 0, 0, xSizeOfTexture, ySizeOfTexture);
	//drawRect(xPos + 5, bottom + 40, 30, 100, 0x000000);
	//drawRect(xPos + 5, bottom + 40, 30, currentPower, 0xd01414);

	fontRendererObj.drawString("Info Block", xPos + 10 + titleXPos, yPos + 4, 0x000000);

	fontRendererObj.drawString("Name: " + player.getDisplayName(), xPos + xSizeOfSideGap + 5 , yPos + ySizeOfBottomGap + 120, 0x000000);
	fontRendererObj.drawString("Time: " + time, xPos + xSizeOfSideGap + 5 , yPos + ySizeOfBottomGap + 100, 0x000000);	
	fontRendererObj.drawString("Location " + "X: " + bStick.xm + " Y: " + bStick.ym + " Z: " + bStick.zm, xPos + xSizeOfSideGap + 5, yPos + ySizeOfBottomGap + 80, 0x000000);

	super.drawScreen(x, y, f);

}

public void initGui(){

	int xSize = 100;
	int ySize = 20;

	int xPos = (xSizeOfTexture) / 2;
	int yPos = (ySizeOfTexture) / 2;

	int bottom = (ySizeOfTexture - ySize - 2);

	buttonList.clear();
	buttonList.add(new GuiButton(0, xPos + xSizeOfSideGap + 100, bottom + ySizeOfBottomGap + 40, 100, 20, format));

	super.initGui();
}


public void actionPerformed(GuiButton button){
	switch(button.id){
	case 0:
		if(timeFormat == true){
			timeFormat = false;
			format = "12 Hour Period";
			sdf = new SimpleDateFormat("h:mm a");
			time = sdf.format(new Date());
		}else{
			timeFormat = true;
			format = "24 Hour Period";
			sdf = new SimpleDateFormat("HH:mm");
			time = sdf.format(new Date());
		}
		break;
	}
	player.addChatComponentMessage(new ChatComponentText("TimeFormat: " + timeFormat));
}

@Override
public boolean doesGuiPauseGame(){
	return false;
}

}

thats the gui code, what about the blocks code

your block should extend BlockContainer or implement ITileEntityProvider

then store the information in the attached tile entity

 

Im sorry Im pretty new, do you have a link somewhere of where I can go to get a better understanding

 

Hi

 

These links might help

http://greyminecraftcoder.blogspot.com.au/2015/01/tileentity.html

and

http://greyminecraftcoder.blogspot.com.au/2015/01/gui-containers.html

 

This link has an example code project which is for 1.8 but is very similar to 1.7

see examples 20 and 30
