[MC-127970] Using Riptide on a trident with an item in your off-hand causes visual glitch with said item

The bug

18w14a added a new animation when using riptide on a trident, which causes the trident item in your hand to be turned horizontally instead of being held on its side as normal.

However, if you have any item in your offhand, the item in your offhand will also be turned horizontally but will also appear at a very strange position on your screen.

How to reproduce

Obtain a riptide trident and a shield

/item replace entity @s weapon.mainhand with minecraft:trident{Enchantments:[{id:"riptide",lvl:3}]}
/item replace entity @s weapon.offhand with minecraft:shield

Ensure that you're in first person, enter some water, and use the riptide enchantment to launch yourself
Look at the shield held in your offhand as you do this, and take note as to whether or not items held in the offhand render in the incorrect position in first person when using a riptide trident
→ ❌ Items held in the offhand render in the incorrect position in first person when using a riptide trident

Expected behavior

Items held in the offhand would not render in the incorrect position in first person when using a riptide trident.

This bug appears to be fixed in 19w02a, but only because at some stage or another in 1.14's snapshots they removed the animation where when you use the riptide trident, in your hand it no longer goes sideways, hence meaning this bug no longer happens.

Cavinator1 2019-01-13T01:53:58Z

Never mind, forget what I said above, another bug was making the animation not play.

As for this bug, it is confirmed for 19w02a.

Yeah found the same thing in 1.14.4, seems to work with many items in off hand like crafting table, golden carrot, bow, bamboo or fishing rod.

migrated 2019-11-04T17:15:57Z

Biggest issue is with shield, because it's just so big. __ It's a little discouraging to use it with trident because it blinds you.

In 20w29a

migrated 2020-10-02T16:48:02Z

This also works the other way round. If you use a riptide trident in your offhand, it causes a visual glitch with the item in the mainhand.

I thought it was intentional:

If you put the riptide trident in your offhand and put a fire aspect sword on your main hand and kill a mob by holding and releading right click, the mob will be "cooked" with the fire aspect sword even though you didnt left click with it.

So it's like you're using the sword along with the trident.

I might be wrong though

migrated 2021-06-05T12:35:17Z

Yeah, same happens if you got a bow in off hand and a sword in the main hand

migrated 2021-07-07T07:15:01Z

can confirm in 1.17. its also even weirder with a shield

Avoma 2021-10-19T08:09:36Z

I am able to confirm this behavior in 21w41a. Here are some extra details regarding this problem.

The Bug:

Items held in the offhand render in the incorrect position in first person when using a riptide trident.

Steps to Reproduce:

Obtain a riptide trident and a shield.

/item replace entity @s weapon.mainhand with minecraft:trident{Enchantments:[{id:"riptide",lvl:3}]}
/item replace entity @s weapon.offhand with minecraft:shield

Ensure that you're in first person, enter some water, and use the riptide enchantment to launch yourself.
Look at the shield held in your offhand as you do this, and take note as to whether or not items held in the offhand render in the incorrect position in first person when using a riptide trident.

Observed Behavior:

Items held in the offhand render in the incorrect position in first person when using a riptide trident.

Expected Behavior:

Items held in the offhand would not render in the incorrect position in first person when using a riptide trident.

Avoma 2021-12-11T13:29:28Z

Can confirm in 1.18.1.

migrated 2021-12-22T22:23:35Z

Code analysis based on 1.18.1 with yarn mappings.

The rendering of the held items is done by net.minecraft.client.render.item.HeldItemRenderer#renderFirstPersonItem(AbstractClientPlayerEntity, float, float, Hand, float, ItemStack, float, MatrixStack, VertexConsumerProvider, int). This method checks player.isUsingRiptide(), and if that is true, then it applies some transformations to the held item. These transformations are fine for tridents, but don't play nicely with some items, such as shields.

The easiest way to fix this would be to only apply the transformations if the item to render is a trident; that is, replace player.isUsingRiptide() with player.isUsingRiptide() && item.isOf(Items.TRIDENT). This keeps the shield (and any other non-trident item) in the normal place:

If not, how could I make the pack myself?

Best way to fix this is just to make it so the first-person riptide animation only plays for the item being used to riptide. If the trident used to riptide is mainhand, the animation only plays for the mainhand, and vice versa.
