Solved How to code a Tipped Arrow with an effect?

So I coded an ItemStack of a tipped arrow but I cant find a way to apply potion effects on it, what's the way to do that?

Thanks in advance

 

@Mr. Sandwich You need to first get the item meta before you can apply potion effects.

 

...
I know its basic but what do I do after that, the question was how to apply the potion effects not what you need to do before that

 

tippedArrow.setBaseBotionData(PotionData data)

new PotionData(PotionType type, boolean extended, boolean upgraded)

 

Code:

sharpArrow.setBasePotionDate(new PotionData(PotionType.INSTANT_DAMAGE, false, true));

Am I doing something wrong? it puts a red line under setBasePotionData and says "The method setBasePotionDate(PotionData) is undefined for the type ItemStack"

 

that method is from the tipped arrow entity. I dont know if there is a way to set it to the ItemStack, but maybe you can add the effects when the arrow spawn

 

I need it to be the right type of tipped arrow in the player's inventory not when it spawns, if anyone knows how to do this please comment

EDIT: I found the solution by myself, you just need to change the meta type to Potion Meta but now I have another question. How do I get this arrow when its shot? I want it to explode when it hits the ground but how can I tell the server that this is this specific arrow?

 

I don't know if this is possible with the arrows... It may be possible by giving the bow a lore value and then doing "EntityShootBowEvent" and checking the lore on the bow used... idk if that's what you want though.

 

You should be able to do this with the ProjectileHitEvent.

 

But how do I detect that this is the right arrow...

 

I don't see how this helps me? I need to know if this arrow is coming from this specific item stack

 

@Mr. Sandwich
That method returns the Arrow's UUID. What you should do is:

• Subscribe to the EntityShootBowEvent.
• Check if the item being shot is your item.
• Store the UUID of the fired Arrow entity.
• In the ProjectileHitEvent, check if the UUID of the arrow that hit is the same as one you stored, if it is, then you know it's your arrow

 

Thanks, solved.
