Fix Version/s: None
Using an eye of ender acts like you are consuming it slowing you down while holding right-click like food or potions. This can be seen better in Creative mode but happens for a short moment in Survival mode as well.
Expected would be that holding right-click would continously throw the eye of enders.
- Switch to Creative mode
- While moving forward hold right-click to use eye of enders
Based on 1.12 decompiled using MCP 9.40 PRE 1
The method net.minecraft.item.ItemEnderEye.onItemRightClick(World, EntityPlayer, EnumHand) sets the eye of ender as actively used item stack similar to bows, food or potions. However, since eye of enders do not override net.minecraft.item.Item.getMaxItemUseDuration(ItemStack) their use time is 0. This causes you to slow down in Creative mode because the condition for stopping using the active item stack is --this.activeItemStackUseCount == 0, so with 0 as start value the first check is -1 == 0.
Since the method ItemEnderEye.onItemRightClick directly decreases the count in Survival the active item stack is reset since its count changed.
