[1.7.10] Custom Rendered arrow positioning

[StarGlas]

Hello all,

 

I am trying to make a mod with custom rendered arrow. Almost everything works except that the arrow is not positions correctly when it hits a block. I have looked up every method of EntityArrow but couldn't find it. Does anybody knows how to position it in a block so it is sticking out a lot instead of how it is now.

[Ewe Loon]

where is the center point of your arrow ?

set it to the tip of the arrow,

[StarGlas]

where is the center point of your arrow ?

set it to the tip of the arrow,

 

Thats the problem. I can't figure out where that is defined. I know that I can use GL11.glTranslatef in the renderer to change it but then the arrow is not in the correct block.
