Wondering about potions

[Sylph3ed]

I'm making a mod where you can use different poison and potions to use in foods and on weapons, but I'm having a problem in getting the potions to actually show up in the brewing tab.  I've got the potion list extended to let me use up to 256 potions, and have one of the potions coded as so:

 

 

Potion Extension

 

@PreInit
public void preInit(FMLPreInitializationEvent event) {
	Potion[] potionTypes = null;

	for (Field f : Potion.class.getDeclaredFields()) {
		f.setAccessible(true);
		try { // Checks the potion name and sees if it fits on the potion
				// types list; also checks the fields to see if it matches
			if (f.getName().equals("potionTypes")
					|| f.getName().equals("field_76425_a")) {
				Field modfield = Field.class.getDeclaredField("modifiers");
				modfield.setAccessible(true);
				modfield.setInt(f, f.getModifiers() & ~Modifier.FINAL);

				potionTypes = (Potion[]) f.get(null);
				final Potion[] newPotionTypes = new Potion[256];
				System.arraycopy(potionTypes, 0, newPotionTypes, 0,
						potionTypes.length);
				f.set(null, newPotionTypes);
			}
		} catch (Exception e) {
			System.err
					.println("Severe error. Please report this to the mod author. (Sylph3ed)");
			System.err.println(e);
		}
	}
	MinecraftForge.EVENT_BUS.register(new PoisonsPlusEventHooks());
}

 

 

Potion Event Handler

 

package mod.sylph3ed.poisonsplus;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.util.DamageSource;
import net.minecraftforge.event.ForgeSubscribe;
import net.minecraftforge.event.entity.living.LivingEvent.LivingUpdateEvent;

public class PoisonsPlusEventHooks {
EntityPlayer player;
@ForgeSubscribe
public void onEntityUpdate(LivingUpdateEvent event) {

	if (event.entityLiving.isPotionActive(PoisonsPlus.potionPainOfHunger)) {
		if (player.getFoodStats().getPrevFoodLevel() < player
				.getFoodStats().getFoodLevel()) {
			event.entityLiving.attackEntityFrom(DamageSource.magic, (player
					.getFoodStats().getFoodLevel() - player.getFoodStats()
					.getPrevFoodLevel()));
		}
		if (event.entityLiving.getActivePotionEffect(
				PoisonsPlus.potionPainOfHunger).getDuration() == 0) {
			event.entityLiving
					.removePotionEffect(PoisonsPlus.potionPainOfHunger.id);
			return;
		}
	}
}
}

 

 

Potion Builder?

 

package mod.sylph3ed.poisonsplus;

import net.minecraft.potion.Potion;


public class PotionPoisonsPlus extends Potion {

public PotionPoisonsPlus(int par1, boolean par2, int par3) {
	super(par1, par2, par3);
	// TODO Auto-generated constructor stub
}


// Set the icon
public Potion setIconIndex(int par1, int par2) {
	super.setIconIndex(par1, par2);
	return this;
}
}

package mod.sylph3ed.poisonsplus;

import net.minecraft.potion.Potion;


public class PotionPoisonsPlus extends Potion {

public PotionPoisonsPlus(int par1, boolean par2, int par3) {
	super(par1, par2, par3);
	// TODO Auto-generated constructor stub
}


// Set the icon
public Potion setIconIndex(int par1, int par2) {
	super.setIconIndex(par1, par2);
	return this;
}
}

 

all you need is this code...

then you should add this into your main file

 

public static Potion potionofmymod = new PotionPoisonPlus(an id over 25).setUnlocalizedName("potionofmymod");

 

To add your potion to an entity

 

player.addPotionEffect(new PotionEffect(mainmodfile.potionofmymod.potionID,200,0))

package mod.sylph3ed.poisonsplus;

public class PotionPoisonsPlus extends Potion {

public PotionPoisonsPlus(int par1, boolean par2, int par3) {
	super(par1, par2, par3);
	// TODO Auto-generated constructor stub
}


// Set the icon
public Potion setIconIndex(int par1, int par2) {
	super.setIconIndex(par1, par2);
	return this;
}
}

public static Potion potionofmymod = new PotionPoisonPlus(an id over 25).setUnlocalizedName("potionofmymod");

player.addPotionEffect(new PotionEffect(mainmodfile.potionofmymod.potionID,200,0))

 

How would you give it a custom icon?

Looks like you can't; it's hardcoded. To the Suggestions board! (With you, I mean. I'm staying here.)

[Sylph3ed]

Alright, but how would I go about putting in my own custom effect for that potion?  I can make all the potions I want, but can't really be a poison without an effect! (Sorry for a lack of posting, but had to do this from a phone, so can't add my own code example...)

Just override performEffect().

[Sylph3ed]

Awesome!  Thanks a ton everyone! 

[Sylph3ed]

Something else came up and I'm not sure if the potion needs its own item.  What I'm trying to do with them is have craftable recipies that apply them to weapons and food.  I'll see what I can come up with, but suggestions are welcome!

Im using this code to add my custom icons...

inventory.png is an edited version of original inventory...

 

 

	@Override
public int getStatusIconIndex() {
Minecraft.getMinecraft().renderEngine.bindTexture("mytextures/gui/inventory.png");
return super.getStatusIconIndex();
}

 

And to select from these icons you use

 

.setIconIndex(2, 0);
.setIconIndex(1, 3);
etc...

Mind if I use this method? Couldn't think of a better way myself!
