Plz answer my questions!

@#7.2.1.1 The code is supossed to by in the item code itself , not in the recipe code.
And if you want have an item have enchanted in the creative inventory public void getSubItems()

@#7.2.1.1.1 It is in the item code, I just coied the recipe with enchant code, in the sword one.

I'm gonna try out how it works that public void, ty.

About the potion effect, I don't really know how to let it work in that class :/

I found tons of similar codes for sword but it seems in MCreator it's a bit different (I guess) and I haven't found any help.

If exists a way to make a sword from item mod in mcreator, would be great, since the 1,5 thing seems to bu bugged, instead of rewrite the sword code from 0.

@#7.2.1.1.1 Holy **** I gave you the wrong code... sry

@#7.2.1.1.1.2.1 Cannot find symbol class List and class SideOnly.

I tried some imports but nothing works

@#7.2.1.1.1.2.1.1 
Tried
import net.minecraftforge.fml.relauncher.SideOnly;
import java.util.List;

?

@#7.2.1.1.1.2.1 OMG... I can't believe the "fix imports" button would be so helpful!

and it all works... I can't believe it's possible... WTF you monster!

Perfect pre-enchanted poisonous weapon

Really thank you

Now I only need a way to edit the sword attack speed and it's all perfect about weapons x)

@#7.2.1.1.1.2.1.1.1 *** poison does not work... or better, it only works on villagers

It doesn't make sense

Still working on everyone if using an item instead of tool

little correction (damn forum where I can't edit messagges): it works on every entityLivingBase except undead and arthropods (zombies, pigzombies, skeleton, spiders) :/

Why this weird thing?! 

@#7.2.1.1.1.2.1.1.1 Everything solved.

except the fact that the weapon does not take damage, it has infinite uses, like the item, since the "onusetick" event seems to not work :/

@#10 From http://minecraft.gamepedia.com/Status_effect#Poison

Undead mobs and spiders are unaffected.

@#10.1 I've found it out when I tried change poison to wither... too much mcreator today i guess

anyway, the weapon has infinite uses (like the item since it seems that the "onUseTick" event does not work and I can't find an updated way to damage the item when it hits an entity)

Do you know why? 

Under "PotionEffect(Potion.getPotionFromResourceLocation("poison"), 200, 2));" put:
  "par1ItemStack.damageItem(1, par2EntityLivingBase); "

@#11 ... it's useless... I'm trying to find something that you don't know, but I always fail x)

Joking

Thank you very much man, it works perfectly
