Also it wont let me launch debug it just highlights this line of code

 

 

The  tileentities stop rendering when they think i cant see them?

 

 

Here is my bitbucket:

https://bitbucket.org/AlphaFox/shipsaddon/src

 

and here is the compiled version download:

http://www.mediafire.com/download/h2quv5hqxfuq2ah/Sails.zip

 

And lastly here is the forum thread on MC forums if u want it:

http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/wip-mods/2384775-sails-masts-addon-for-ships-mod-90-complete

Um is anyone gonna help?

 

Please Post the relevant code(TileEntity and TileEntitySpecialRenderer) here, the Bitbucket does not allow to see the code without login. (or is it private? Then we cannot help you)

Seems like your "RenderMast" class has a function in it that is returning null. May we see that?

sorry i am new to bitbucket and modding in general. It is now public

this is the TileEntitySpecialRenderer

Ok well i have solved half the problem 

//Shape1.mirror = true;

http://www.minecraftforge.net/forum/index.php/topic,29024.0.html

pointed me in the right direction. What is Shape1.mirror supposed to do anyway?

 

 

however i am still getting the disapearing TE problem http://prntscr.com/6mrtsl

whenever i tun my screen to far it seems to assume i cant see the block anymore then it hides it.

Oh u mean put

getRenderBoundingBox()

in the TE class as sugested here: http://www.minecraftforge.net/forum/index.php?topic=14475.0

thanks i would have gotten that otherwise

@Override
public AxisAlignedBB getRenderBoundingBox()
{
	return AxisAlignedBB.getBoundingBox(xCoord, yCoord, zCoord, xCoord + 1, yCoord + 1, zCoord + 1);
}
