Hi guys I'm trying to make a Katana, wich will basically be a sword but faster, but i don't know how to change it's speed.

This is the code for my katana (it's just a copy of the ItemSword class), how can i make it faster (i mean if you click with a sword it does an animation to attack, so you can't attack every second until the animation is over, how can i speed up this animation?)

That doesn't speed up the animation, it just lets the target get hurt immediately.

I was just posting that it doesn't change the animation speed

up

The potion effect Haste speeds up the animation for hitting, though it also does for block breaking. Try taking a look at it to see how you can achieve the same effect - remember to consider the speeding-up of block breaking.

I tried before looking the code for the Haste effect but i didn't find that

Use your IDE. In Eclipse, I found a couple pieces of code relating specifically to this.

 

1.) The Potion Effect Declaration - This is found in net.minecraft.potion.Potion

//Potion effect is declared below

public static final Potion digSpeed = (new Potion(3, new ResourceLocation("haste"), false, 14270531)).setPotionName("potion.digSpeed").setIconIndex(2, 0).setEffectiveness(1.5D);

 

2.) The Swing Animation Speed - This is found in net.minecraft.entity.EntityLivingBase

//Modify the below method

/**
     * Returns an integer indicating the end point of the swing animation, used by {@link #swingProgress} to provide a
     * progress indicator. Takes dig speed enchantments into account.
     */
    private int getArmSwingAnimationEnd()
    {
        return this.isPotionActive(Potion.digSpeed) ? 6 - (1 + this.getActivePotionEffect(Potion.digSpeed).getAmplifier()) * 1 : (this.isPotionActive(Potion.digSlowdown) ? 6 + (1 + this.getActivePotionEffect(Potion.digSlowdown).getAmplifier()) * 2 : 6);
    }

 

Looking at the above modified code found in the paths provided, the first example declares the effect. The second example is what you want to look at, as it returns an integer pertaining to the end of the "swing animation".

After a bit more searching, I came across this field, which you can modify using reflection.

 

Field SwingProgressInt - Found in net.minecraft.entity.EntityLivingBase

//Change this to your needed speed - be sure to pay attention to the methods regarding this field below

public int swingProgressInt;

Oh, that's why i didn't find the code, it was in the entity class. Also i tried do "Search in file" in eclipse but it gives me an error i don't know why I'll try working with that parameters and let you know, thanks

Ok, so i've tried doing that, but i don't know how to refer that variable using reflection What is the instruction to do that?

Ok, so i've overrited this method

@Override
public boolean onLeftClickEntity(ItemStack stack, EntityPlayer player, Entity entity)
{
	player.swingProgressInt = 1;
	return this.hitEntity(stack, (EntityLivingBase) entity, player);
}

and my katana is faster (wich is what i want), BUT if i hit an entity it doesn't deal damage

Try adding super.onLeftClickEntity to the beginning of your method.

Ok, so i've looked into the super method wich is only a return false statement. So i changed my function to this and it worked

@Override
public boolean onLeftClickEntity(ItemStack stack, EntityPlayer player, Entity entity)
{
	player.swingProgressInt = 3;
	return false;
}

 

Also fun fact: it seems that i can make my item only faster but not slower.
