Hey!

So for example, if I have to launch the player when they right click, I would launch them a certain amount, like so:

	@Override
    public ActionResult<ItemStack> onItemRightClick(ItemStack stack, World world, EntityPlayer player, EnumHand hand)
    {
        //Just showing an example, I know this looks stupid...
        player.motionY = 0.5D;
        player.fallDistance = 0;
        
        return new ActionResult<>(EnumActionResult.SUCCESS, stack);
    }

But how do I edit the amount to satisfy all the levels of Jump Boost if the potion effect is active? (Level I, II, III, etc.)

Please help

EntityLivingBase::getActivePotionEffect will give you any active potion effect for that entity based on the potion. Then you can access the modifier using PotionEffect::getAmplifier.

What's the getter method for PotionEffect?

Sorry, I'm having a hard time to locate my IDE.

Which PotionEffect? Please clarify what you are looking for.

PotionEffect::getAmplifier

What is the getter for PotionEffect?

Got it. Thanks!

Do not use getPotionById. Use the constants defined in the MobEffects class.

 

Why not though? Does it give errors or something?

Numerical IDs change, they are not constant.

I see.

I'll use MobEffects::JUMP_BOOST then.

Thanks!

Thankfully I'm smart in math

if (player.getActivePotionEffect(MobEffects.JUMP_BOOST) != null)
{
	double amplifier = player.getActivePotionEffect(MobEffects.JUMP_BOOST).getAmplifier();
	player.motionY = ((amplifier + 0.45D) * 1.25D) - (amplifier * 1.1D);
}
else
{
	player.motionY = 0.45D;
}

Thanks again

Why are you calling the method twice...

What do you mean? amplifier?

8 minutes ago, diesieben07 said:

There is only one method that is being called twice inside the code snippet that you posted. It is not amplifier, there is no reference to such a method in that snippet anywhere (you do have a local variable named amplifier though).

else { player.motionY = 0.45D? }

I don't see what you mean here.

You're either talking about 

player.getActivePotionEffect(MobEffects.JUMP_BOOST)

or

player.motionY

I don't see anything I called twice. Be more specific please?

I see what you mean.

but amplifier is .getAmplifier(); method...

Which is being called - let's count together - once, that's right. So it's not what I am talking about.

So you're basically telling me to remove the null check...

No. I am telling you to not call getActivePotionEffect twice. Simple as that.

PotionEffect effect = player.getActivePotionEffect(MobEffects.JUMP_BOOST);
                    
if (effect != null)
{
	double amplifier = effect.getAmplifier();
                    	
	player.motionY = ((amplifier + 0.45D) * 1.25D) - (amplifier * 1.15D);
}
else
{
	player.motionY = 0.45D;
}
