[1.7.10] Checking if inventory is full and rendering it into the screen

[q8minecraft]

Hello..

I'm trying to code this mod which tells you if you're inventory is full, and if it is, it render the stats (GUI) into the screen, For example I have a simple GUI on the left corner of my screen that says Inventory stats: Full <-- that's if its full, If its not full and can still contain items it says Inventory stats: Empty

So here's my code..

Main class

package me.q8minecraft.fullinv;

 

import com.q8minecraft.event.ScreenRender;

 

import net.minecraftforge.common.MinecraftForge;

import cpw.mods.fml.common.Mod;

import cpw.mods.fml.common.Mod.EventHandler;

import cpw.mods.fml.common.event.FMLInitializationEvent;

 

 

@Mod(modid = FullInv.MODID, version = FullInv.VERSION, name = FullInv.NAME)

public class FullInv {

 

public final static String MODID = "FullInv";

public final static String NAME = "FullInv";

public final static String VERSION = "1.0.0";

 

@EventHandler

public void init(FMLInitializationEvent e) {

MinecraftForge.EVENT_BUS.register(new ScreenRender());

}

}

 

 

 

ScreenRender class:

 

package com.q8minecraft.event;

 

import cpw.mods.fml.common.eventhandler.SubscribeEvent;

import net.minecraft.client.Minecraft;

import net.minecraftforge.client.event.RenderGameOverlayEvent;

import net.minecraftforge.client.event.RenderGameOverlayEvent.ElementType;

 

public class ScreenRender {

 

@SubscribeEvent

public void renderOverlay(RenderGameOverlayEvent e) {

if(e.type == ElementType.JUMPBAR || e.type == ElementType.EXPERIENCE) {

Minecraft.getMinecraft().fontRenderer.drawString("Inventory Stats: ", 2, 2, 0xFFFFFF);

 

 

}

}

 

}

Anyone can help me with this mod ?

I have a tutorial examples showing you how to modify the overlay:

 

https://github.com/Nephroid1/MinecraftByExample/tree/master/src/main/java/minecraftbyexample/overlay_simple

https://github.com/Nephroid1/MinecraftByExample/tree/master/src/main/java/minecraftbyexample/overlay_advanced

 

The second one renders an HP bar, so it shows you how to access player information while rendering the overlay. The same concepts apply if you want to render other things, like the inventory status of a player.

 

In general, you only want to handle the RenderGameOverlay.Post and RenderGameOverlay.Pre events, not the RenderGameOverlayEvent itself. For rendering a bit of text, it's only necessary to render it once per screen update. The code you have right now would render your text at least four times (twice in the pre event and twice in the post event; once for the jump bar, once for the exp bar), which is extra, unnecessary work.

 

 

Also, when asking for help, it's a good idea to actually say what you're having problems with. That way, people can actually help you with your problem.
