[1.14.4][Solved] Items events

[Brbcode]

is there any way to detect that I am holding an item or blockitem? and if I stop holding it?

 

How get held item:

Item heldItem = Minecraft.getInstance().player.getHeldItemMainhand().getItem();

Everything you hold is an ItemStack of some Item. If you want to know if it is a BlockItem you have to instanceof the stack's item.

 

I don't know that there is an event for when the player changes their held item, however.

ItemStack

Honestly, I am not sure how to handle the item stack, can I create my custom item stack and register it?,

I have found a method called "interactWithEntity(PlayerEntity playerIn, LivingEntity entityIn, Hand hand)" so it seem that is the correct way to archive my goal.

Entities can be another way I think...

No. ItemStack is a sealed class.

I don't see how this is even remotely close to what you asked for.

What exactly are you trying to achieve (from the perspective of someone using your mod, not how you want to program it)?

My custom mod is like a barrier that only works with fluids letting the player go through it. To build water elevators more easy.

So I want change the render of my block to invisible or visible in function if player holds in his hand the item or not.

Your block will need a tile entity and a TileEntityRenderer (use TileEntityRendererFast if at all possible). Then in there you check if Minecraft#renderViewEntity is holding your item.

 I still have to finish how to show the texture, I don't know how yet but you have given me a good hint, Thank you.
