Plz answer my questions!

1.) Probably Not

2.) Weapons Yes, Armor No

3.) you can make items glow if you make them enchanted (make a recipe then do <add enchant>)

4.) No, unless you code

5.) No, unless you know coding

6.) Yes Drewpy did a post on this in the (User Self Tutorials) section

7.) No, unless you go to global events and do something there.

8.) Cause Later Versions Are Fabulous.

9.) Spooky Ghost O.O

10.) try schematics? or the custom trees in the creator.

11.) Something work with these events, some do not

12.) with Coding

2) You can override method getArmorModel to make it return your model class that extends ModelBiped.
3)

  @SideOnly(Side.CLIENT)
    public boolean hasEffect(ItemStack stack)
    {
        return true;
    }

4)

                    public void addInformation(ItemStack itemstack, EntityPlayer par2EntityPlayer, List list, boolean par4)
{
                       itemstack.setStackDisplayName(EnumChatFormatting.GRAY + I18n.format(this.getUnlocalizedName() + ".name"));
}

+ You need import I18n!

7)
Yes  you can , but the method to do it depends on what change do you want to do.

9)

Because it is bug :D It is fixed in upcoming update of MCreator , or there I made a tutorial:

12)
Try:
 

public boolean hitEntity(ItemStack par1ItemStack, EntityLivingBase par2EntityLivingBase, EntityLivingBase par3EntityLivingBase) { par2EntityLivingBase.addPotionEffect(new PotionEffect(Potion.EFFECT.id, TIME, AMPLIFIER)); par1ItemStack.damageItem(1, par2EntityLivingBase); return true; }

Nuparu00 Is MCreator God!!

@#5 what and why do you need separate it?

Did you paste it to the ItemSword instance or to a class that extends ItemSword?
Can show the error + code?

And yes , it must be for example : Potion.wither.id

I have a few issues I ran into with MCreator for 1.7.10 as well. I would appreciate help on as many as you can:

1.) I want to make foods that imbue multiple effects when eaten, but when I do this as a stacked event, I can't eat the food and nothing happens. How do i fix this?

2.) Is it possible to make a dimension with multiple biomes in it? if yes, then how?

3.) I want to make "anti-bonemeal" which turns plants/sapling into dead bushes and grass into a different block; how do i do this, rather than have it turn everything into a dead bush

4.) how do I make single-use items (like bone meal, spawn eggs, or fire charges)?

5.) how do you make a structure schematic?

6.) how do you code in monster spawners for custom mobs with commands? (ex. /setblock mob_spawner ~ ~ ~ {???})

7.) my nether-like dimension seems to crash the game and corrupt the world. Why?

8.) Since i figure most (or all) my problems will require coding, how do you insert said coding into the MCreator mod's code, if possible

@#7 Hi, I come in the middle of this just to say I get this:

cannot find symbol
     par2EntityLivingBase.addPotionEffect(new PotionEffect(Potion.Poison.id, 40, 2));

I've already imported entitylivingbase, potioneffect, and potion too, tried to write it like this: POISON, poison, but still get this error :/

@#7 Aaaaand I made it work!

But only if I create an item mod and sword class (1,5 in type of tool) and it seems that it doesn't work as I expect... It isn't a sword, it's a normal item that deals 1 of damage :/

How can I fix this so I can obtain a sword with an attack damage?

btw here the code to add at the end, just before last 2 brackets:

@Override
         public boolean hitEntity(ItemStack par1ItemStack, EntityLivingBase           par2EntityLivingBase, EntityLivingBase par3EntityLivingBase) {
          par2EntityLivingBase.addPotionEffect(new PotionEffect(Potion.getPotionFromResourceLocation("poison"), 200, 2));
          par1ItemStack.damageItem(1, par2EntityLivingBase); 
          return true; 
          } 

Now you got a poisonous item (10 sec of poison level 3)

@#7.2 Can I see the whole code that you used in the original sword code that did not work?

@#7.2.1 here it is:

          par1ItemStack.damageItem(1, par2EntityLivingBase); 
          return true; 
          }          
         
         }

I've added the enchantment when crafted, even if i'd like to know if there's the possibility to have a pre-enchanted sword, without having a recipe for it
