I have copied an ArrowEntity and Render from Minecraft and deleted some unnecesary functions.
It works fine, but at the far distance.
When Kunai its the ground to 5 blocks from Player it goes back where it was some ticks before hit.
But it is only Render because when I want to pickup I have to get in a position where Kunai should be on the ground.
[spoiler=Picture showing it]
Shooting from place where orange wool is.
