Hey,

I have my fluid registered and working (it works in a bucket and also shows up in the world), but I want to know how to make it change items that are dropped in it (like PneumaticCraft's etching acid, or the fluix seeds in AE2). I have looked all over the internet and can't find a reference as to how to do something like this anywhere. I would imagine that the fluid could have some sort of function which fires when an item is dropped into it and gives me back the ItemStack to play with, but that sounds too easy

 

I'm thinking along the lines of the

public ItemStack onItemRightClick(ItemStack is, World world, EntityPlayer ep) 

function for items, but I could be completely wrong. Any suggestions?

 

Thanks,

Since liquid don't have collision bounding box, 'ontemRightClick' would not work.

Instead, you have to do it on PlayerInteractEvent, and check for collision into the fluid block. (Also, it would be CLICK_AIR mode)

@Abastro I wasn't wanting a right-click to happen anyway, I was just using that method as an example of something similar to what I want to do. To put it in clearer terms, I want the liquid to alter items dropped into it using the Q key - for example, if I drop in four gold the ItemStack changes into one diamond. I was wondering if there was a method similar to onItemRightClick but for detecting if an item was dropped into a liquid (onItemDropped maybe)

Actually it does.  Just not most of the time.  How do you think the boat item works?

There seems to be no event for that. You should use EntityItem#onUpdate().

EDIT: You should spawn custom EntityItem when the item is dropped.

@Draco18s: Oh. I didn't know that;

I agree that a custom entity item should work. It can check position to see if it is in the fluid.

You don't need a custom entity for this.

onEntityCollidedWithBlock in fluid block class, works for me... (And is the best way for custom fluid!!!)

@elix onEntityCollidedWithBlock sounds like exactly what I need! Now to see if it actually will work...
