Creating on-hit effects on tools!

Creating on-hit effects
Hello and welcome to my tutorial on how to create on-hit effects on your tools! This tutorial will teach you on how to add potion effects to mobs when you hit them with a tool.

Step 1:
Since there is no on-hit procedure in tools we will be coding in it ourselves, so go on ahead and create your tool.

Step 2:
Select your tool and click on the "Edit the code of the selected mod element" the button should look like this "</>".

Step 3:
Override the public boolean "hitEntity", here's the code if you don't know how to:

@Override
public boolean hitEntity(ItemStack stack, EntityLivingBase target, EntityLivingBase attacker) 
{
	return true;
}

Make sure it is placed inside the class that extends the tool, not the mod element.

Step 4:
Currently, the code itself isn't going to do anything, so, insert this next bit of code on top of return true:

target.addPotionEffect(new PotionEffect(MobEffects.WITHER, 100, 2, false, false));

This is the code that gives out the effect, the important part here is the "new PotionEffect()" part, I'll be explaining it now.

• The first argument is the effect that it's gonna give, there are a lot more effects, test them out.

• The second argument determines how long the potion lasts in ticks, 20 ticks is a second. I've set mine to 100 ticks so that the wither effect would last for 5 seconds.

• The third argument, determines the strength of a potion, I've set it to 2 so that it gives out a Wither III effect.

• The fourth argument makes the particles less visible.

• The fifth argument determines if the particles are visible or not.

That is the end of my tutorial, if you need some help, leave a comment. Also, tell me if there's something wrong, I have never tested this in a mod element due to me being unable to create mod elements for some reason.
