Armour Potion Effects

ashtonr12 · March 7, 2013

This is my current ServerTickHandler file;

package ashtonsmod.common;

import java.util.EnumSet;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.item.ItemStack;

import net.minecraft.potion.Potion;

import net.minecraft.potion.PotionEffect;

import cpw.mods.fml.common.ITickHandler;

import cpw.mods.fml.common.TickType;

public class ServerTickHandler implements ITickHandler {

private void onPlayerTick(EntityPlayer player) {

if (player.getCurrentItemOrArmor(4) != null ) {

ItemStack helmet = player.getCurrentItemOrArmor(4);

ItemStack chest = player.getCurrentItemOrArmor(3);

ItemStack legs = player.getCurrentItemOrArmor(2);

if (helmet.getItem() == ashtonsmod.ObsidianHelmet ) {

player.addPotionEffect((new PotionEffect(Potion.moveSlowdown.getId(), 25, 1)));

}

if(player.getCurrentItemOrArmor(1) != null){

ItemStack boots = player.getCurrentItemOrArmor(1);

if(boots.getItem() == ashtonsmod.ObsidianBoots){

player.addPotionEffect((new PotionEffect(Potion.moveSlowdown.getId(), 25, 1)));

}}

if(player.getCurrentItemOrArmor(2) != null){

ItemStack legs = player.getCurrentItemOrArmor(2);

if(legs.getItem() == ashtonsmod.ObsidianLegs){

player.addPotionEffect((new PotionEffect(Potion.moveSlowdown.getId(), 25, 1)));

}}

if(player.getCurrentItemOrArmor(3) != null){

ItemStack plate = player.getCurrentItemOrArmor(3);

if(plate.getItem() == ashtonsmod.ObsidianPlate){

player.addPotionEffect((new PotionEffect(Potion.moveSlowdown.getId(), 25, 1)));

}}}

@Override

public void tickStart(EnumSet<TickType> type, Object... tickData)

{

if (type.equals(EnumSet.of(TickType.PLAYER)))

{

onPlayerTick((EntityPlayer)tickData[0]);

}

@Override

public EnumSet<TickType> ticks()

{

return EnumSet.of(TickType.PLAYER, TickType.SERVER);

}

@Override

public void tickEnd(EnumSet<TickType> type, Object... tickData) {

}

@Override

public String getLabel() {

return null;

}

This currently says that if i put on obsidian armour (helmet or plate or boots or legs) it gives me slowness effect, how would i go about making it so that when i put on obsidian armour (helmet and plate and boots and legs) it gives me the potion effect? (ignore any missing } i cut out a small part of code.)

down load this src code and Replace and edit your sever tick handler with it

src code: http://thegrovesyproject101.weebly.com/armor-potion-effects.html

ashtonr12 · March 7, 2013

i watched you videos your totally like famous!

ashtonr12 · March 7, 2013

anywhat that doesnt work it only gives me the potion effect when i have either the hat or plate on , i would like ti so that if any part of the set is omitted the potion effect no longer activates

TheGrovesyProject101 · March 7, 2013

what so that you have to have a full set of the armor?

ashtonr12 · March 7, 2013

so that you have to be wearing all four peices of the armour set to get the effect

e.g

helmet+plate+legs+boots = potion.moveslowness

plate+Legs+Boots = no potion effect

helmet + legs + plate = no potion effect

boots + plate = no potion effect

etc

oh right then replace your server tick handler with this

package modding.tutorial;

		ItemStack helmet = player.getCurrentItemOrArmor(4);
		ItemStack plate = player.getCurrentItemOrArmor(3);

			player.addPotionEffect((new PotionEffect(Potion.confusion.getId(), 200, 0)));
		}
	}

}

@Override

}

}

ashtonr12 · March 8, 2013

then what do you suggest?

ashtonr12 · March 8, 2013

ok example code?

and what class is this meant to go in?

ashtonr12 · March 8, 2013

example item class?

ashtonr12 · March 8, 2013

i am not a great modder sorry, so how would i make it so that all four armour pieces have to be equipped to activate the potion effect

ashtonr12 · March 8, 2013

so example item code?

ashtonr12 · March 8, 2013

This is the modding support forums isnt it? this is not the go away and learm java than come back and ask for help forum, by asking for an example i amtrying to learn new methods and codes. For next time i can use this without you

		if (player.getCurrentItemOrArmor(4) != null && player.getCurrentArmor(3) != null && player.getCurrentItemOrArmor(2) != null && player.getCurrentItemOrArmor(1) != null) {
		ItemStack helmet = player.getCurrentItemOrArmor(4);
		ItemStack plate = player.getCurrentItemOrArmor(3);
		ItemStack legs = player.getCurrentItemOrArmor(2);
		ItemStack boots = player.getCurrentItemOrArmor(1);

			player.addPotionEffect((new PotionEffect(Potion.confusion.getId(), 200, 0)));
		}
	}

put that in the onArmorTickUpdate method

ashtonr12 · March 9, 2013

Thanks a bunch dude, that seems great!

ashtonr12 · March 9, 2013

this seems to work but it randomly crashes sometimes when i put the Armour set on?

/Edit/

This also seems to make the entire game run slower especially on startup?

it still seems to crash when i have a full Armour set on and i take of the plate, any other armors are fine?

ashtonr12 · March 9, 2013

I am confused i though i was meant to put that code in my server tick file?

as when i put it in my armour class it doesnt do anything?

ashtonr12 · March 9, 2013

ok, i know i am really rubbish at this?

here is my item class, what do i do with it?

package ashtonsmod.common;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.EnumArmorMaterial;
import net.minecraft.item.ItemArmor;
import net.minecraft.item.ItemStack;
import net.minecraft.potion.Potion;
import net.minecraft.potion.PotionEffect;
import net.minecraftforge.common.IArmorTextureProvider;

public class ObsidianHelmet extends ItemArmor implements IArmorTextureProvider{

        public ObsidianHelmet(int par1,EnumArmorMaterial par2EnumArmorMaterial, int par3, int par4) {
                super(par1, par2EnumArmorMaterial, par3, par4);
        }
        
        

	@Override
    	public String getTextureFile(){
    		return CommonProxy.items_png;
         }

        public String getArmorTextureFile(ItemStack par1){
                if ( par1.itemID==ashtonsmod.ObsidianHelmet.shiftedIndex|| par1.itemID==ashtonsmod.ObsidianPlate.shiftedIndex||
                                 par1.itemID==ashtonsmod.ObsidianBoots.shiftedIndex){
                        return "/armor/ObsidianArmor_1.png";
                }if(par1.itemID==ashtonsmod.ObsidianLegs.shiftedIndex){
                        return "/armor/ObsidianArmor_2.png";
                }return "/armor/ObsidianArmor_2.png";
        }
}

this seems to work but it randomly crashes sometimes when i put the Armour set on?

This also seems to make the entire game run slower especially on startup?

your supposed to put the method in your armor file. don't use a tick handler for that.

ashtonr12 · March 9, 2013

thank you very much i have sorted it.

MrProg · May 14, 2013

I have the same "Take chestplate off and the game crashes bug". How did you fix this? This will help me alot! Thanks!

EDIT: Nevermind I fiddled around and got it to work !
