[1.7] Creating a new bar, like the armor bar.

[Alex_Richard]

Hey, i want to create a new bar above the armor that displays the players armor weight. I cant find any good tutorials on this at all, and would really appreciate some help, examples encouraged. Heres my current code for applying armor weight and such:

 

package MinecraftRPGOverhaul.items;

import java.awt.List;
import java.util.ArrayList;
import java.util.Arrays;

import cpw.mods.fml.common.ObfuscationReflectionHelper;
import net.minecraft.block.material.Material;
import net.minecraft.entity.Entity;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.player.PlayerCapabilities;
import net.minecraft.init.Items;
import net.minecraft.item.Item;
import net.minecraft.item.ItemArmor;
import net.minecraft.item.ItemStack;
import net.minecraft.item.ItemArmor.ArmorMaterial;
import net.minecraft.potion.Potion;
import net.minecraft.potion.PotionEffect;
import net.minecraft.world.World;

public class ModArmor extends ItemArmor{

//set the different weight classes
private static final float DIAMOND = 6.25f;
private static final float IRON = 5.00f;
private static final float GOLD = 3.75f;
private static final float CHAIN = 2.50f;
private static final float LEATHER = 1.25f;

//weight for each armor piece
private static float bootWeight = 0.0f;
private static float chestplateWeight = 0.0f;
private static float helmetWeight = 0.0f;
private static float leggingWeight = 0.0f;

//total armor weight
public static float totalWeight = 0.0f;

public static Item diamondArmor[] = new Item[] { 
	Items.diamond_boots, 
	Items.diamond_chestplate, 
	Items.diamond_leggings, 
	Items.diamond_helmet };

public static Item ironArmor[] = new Item[] { 
	Items.iron_boots, 
	Items.iron_chestplate, 
	Items.iron_leggings, 
	Items.iron_helmet };

public static Item goldArmor[] = new Item[] { 
	Items.golden_boots, 
	Items.golden_chestplate, 
	Items.golden_leggings, 
	Items.golden_helmet };

public static Item chainArmor[] = new Item[] { 
	Items.chainmail_boots, 
	Items.chainmail_chestplate, 
	Items.chainmail_leggings, 
	Items.chainmail_helmet };
public static Item leatherArmor[] = new Item[] { 
	Items.leather_boots, 
	Items.leather_chestplate, 
	Items.leather_leggings, 
	Items.leather_helmet };

public String textureName; //The texture name, the name is passed in via the 'ModArmor' method

public ModArmor(String unlocalizedName, ArmorMaterial material, String textureName, int type){ //ModArmor method, passes in all pertinent information to create a piece of armor
    
	super(material, 0, type);
    this.textureName = textureName;
    this.setTextureName(unlocalizedName);
}

@Override
public String getArmorTexture(ItemStack stack, Entity entity, int slot, String type){ //getArmorTexture method, uses previous information passed in to assure you have the right texture

	return "rpgmod" + ":armor/" + this.textureName + "_" + (this.armorType == 2 ? "2" : "1") + ".png";

}

public static float armorCall(EntityPlayer player) {

	totalWeight = setCurrentArmorWeight(player);

    return (((100f - totalWeight) / 1000));
    

}

public static float setCurrentArmorWeight(EntityPlayer player) {

	player.capabilities.setFlySpeed(0);

		if (player.getCurrentArmor(0) != null) {
			for(int x = 0; x < 4; x = x+1) {
				if (player.getCurrentArmor(0).getItem().equals(diamondArmor[x])) {					
					bootWeight = DIAMOND;			
				}
				if (player.getCurrentArmor(0).getItem().equals(ironArmor[x])) {					
					bootWeight = IRON;			
				}
				if (player.getCurrentArmor(0).getItem().equals(goldArmor[x])) {					
					bootWeight = GOLD;			
				}
				if (player.getCurrentArmor(0).getItem().equals(chainArmor[x])) {					
					bootWeight = CHAIN;			
				}
				if (player.getCurrentArmor(0).getItem().equals(leatherArmor[x])) {					
					bootWeight = LEATHER;			
				}
			}
		}

		else {
			bootWeight = 0;
		}
		if (player.getCurrentArmor(1) != null) {
			for(int x = 0; x < 4; x = x+1) {
				if (player.getCurrentArmor(1).getItem().equals(diamondArmor[x])) {					
					leggingWeight = DIAMOND;			
				}
				if (player.getCurrentArmor(1).getItem().equals(ironArmor[x])) {					
					leggingWeight = IRON;			
				}
				if (player.getCurrentArmor(1).getItem().equals(goldArmor[x])) {					
					leggingWeight = GOLD;			
				}
				if (player.getCurrentArmor(1).getItem().equals(chainArmor[x])) {					
					leggingWeight = CHAIN;			
				}
				if (player.getCurrentArmor(1).getItem().equals(leatherArmor[x])) {					
					leggingWeight = LEATHER;			
				}
			}
		}
			else {
				leggingWeight = 0;

		}
		if (player.getCurrentArmor(2) != null) {
			for(int x = 0; x < 4; x = x+1) {
				if (player.getCurrentArmor(2).getItem().equals(diamondArmor[x])) {					
					chestplateWeight = DIAMOND;			
				}
				if (player.getCurrentArmor(2).getItem().equals(ironArmor[x])) {					
					chestplateWeight = IRON;			
				}
				if (player.getCurrentArmor(2).getItem().equals(goldArmor[x])) {					
					chestplateWeight = GOLD;			
				}
				if (player.getCurrentArmor(2).getItem().equals(chainArmor[x])) {					
					chestplateWeight = CHAIN;			
				}
				if (player.getCurrentArmor(2).getItem().equals(leatherArmor[x])) {					
					chestplateWeight = LEATHER;			
				}
			}
		}
			else {
				chestplateWeight = 0;

		}
		if (player.getCurrentArmor(3) != null) {
			for(int x = 0; x < 4; x = x+1) {
				if (player.getCurrentArmor(3).getItem().equals(diamondArmor[x])) {					
					helmetWeight = DIAMOND;			
				}
				if (player.getCurrentArmor(3).getItem().equals(ironArmor[x])) {					
					helmetWeight = IRON;			
				}
				if (player.getCurrentArmor(3).getItem().equals(goldArmor[x])) {					
					helmetWeight = GOLD;			
				}
				if (player.getCurrentArmor(3).getItem().equals(chainArmor[x])) {					
					helmetWeight = CHAIN;			
				}
				if (player.getCurrentArmor(3).getItem().equals(leatherArmor[x])) {					
					helmetWeight = LEATHER;			
				}
			}
		}
			else {
				helmetWeight = 0;

		}

		return bootWeight + helmetWeight + chestplateWeight
				+ leggingWeight;

}

}

 

And heres the event that modifies the players speed and a little test GUI i did:

 

package MinecraftRPGOverhaul.events;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.player.PlayerCapabilities;
import net.minecraftforge.client.event.RenderGameOverlayEvent;
import MinecraftRPGOverhaul.ModGUI.ModGUI;
import MinecraftRPGOverhaul.items.ModArmor;
import cpw.mods.fml.client.FMLClientHandler;
import cpw.mods.fml.common.ObfuscationReflectionHelper;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.TickEvent;
import cpw.mods.fml.common.gameevent.TickEvent.Phase;
import cpw.mods.fml.common.gameevent.TickEvent.PlayerTickEvent;

public class ModEventHandler {

@SubscribeEvent
public void onEntityUpdate(PlayerTickEvent event) {

	event.player.capabilities.setPlayerWalkSpeed(ModArmor.armorCall(event.player));
	System.out.println((ModArmor.armorCall(event.player)));

}

@SubscribeEvent
public void onOverlayRender(RenderGameOverlayEvent event) {

	if (event.type == RenderGameOverlayEvent.ElementType.ALL) {
		FMLClientHandler.instance().getClient().fontRenderer.drawStringWithShadow("Armor Weight(Speed): " + String.format("%.2f", (100 - ModArmor.totalWeight)) + " Percent", 0, 0,16777215);
	}
}

}

 

I know its not the best code but im still figuring things out, I believe currently it wouldn't work with SMP but thats okay for now! Basically i want to have a bar that has 10 little weights, and for ever 2.5 "weight" (The totalWeight variable), i would like to display half a GUI weight as a visual representation! If someone could help me figure this out or point me to a tutorial that is more relevant to this, then that would be great!

 

Thanks in advance as i know its quite the big question/undertaking.

Awesome tutorial by cool alias.

That only seems to be events, which i do know how to use. I need help with how to render and such! Thanks though, I bookmarked it in-case i ever need it!

 

Edit: By know how to use events, i mean i know how to use the render event and such, I just don't know how to create a functioning bar akin to the armor bar.

Hi

 

This tutorial project has a working example of changing the overlays including the armour bar

 

https://github.com/TheGreyGhost/MinecraftByExample

(see MBE40)

https://github.com/TheGreyGhost/MinecraftByExample/blob/master/src/main/java/minecraftbyexample/mbe40_hud_overlay/Notes.txt

 

It's for 1.8 but 1.7.10 is more or less identical.

Thanks a ton, I'm reading it right now!

You didn't read the post did you?

 

The post has the extended properties tutorial below it and how to make the gui overlay.
