Posted July 3, 201411 yr 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.

August 6, 201411 yr I have own projectile too and the problem is the same. I read is some topic that it's forge bug or sth similar. I read also that this problem can be fixed, by mod maker, but it's hard.
August 7, 201411 yr Hi You might find this topic interesting. http://www.minecraftforge.net/forum/index.php/topic,14315.msg73758.html#msg73758 Easiest solution = derive from EntityArrow not Entity. Not 100% sure it still works but it's worth a try. -TGG
August 11, 201411 yr Author Changing to EntityArrow fixed the problem, but made a 20 ticks long lag of dissapear when hit Block in close distance. Thanks
