How to make an item change on right click

[SkylordJoel]

Hi,

I am creating a mod where you click a package and it turns into a sword. How would I do this? I would prefer it to not do damage as a package but just changing sprites would be good enough.

Thanks.

Hi

 

I'd suggest:

Override Block.onBlockClicked or Block.onBlockActivated to change the block metadata.  You'll also need to call World.markBlockForUpdate to make sure that the new texture is drawn.

 

Override BLock.getBlockTexture to return a different texture based on the metadata.

 

If you're not familiar with metadata, this might help

I meant an item. But thanks, very interesting.

I forgot to put that the item would be acting like a sword and taking damage.

You can use ItemStack nbt and the onItemRightClick method.

[SkylordJoel]

So how do you use that? (Isn't NBT like a string or something?)

Hi

 

What do you mean "click on a package" exactly?  In the inventory screen?

 

The method GotoLink has suggested (if I've understood his/her suggestion correctly) is called when you're holding the item and you press the right mouse button.

Yeah, there is a picture of a package in the inventory, and it turns into a sword and back again.

Hi

 

Hmmm that sounds like it will be tricky.

 

The code that handles clicks on items in the inventory is

GuiContainer.mouseClicked

 

I don't see an easy way to intercept it without changing one of the base classes or (eg) writing a class that overrides PlayerControllerMP.windowClick to intercept the click, and replacing Minecraft.playerController with your new class.  That's getting a bit hard to do robustly and I'm not confident it would work.
