Model randomly vanishes depending on where I look..

[Flenix]

Hey guys,

 

 

I'm adding my blocks to the game as TileEntities. However, when I look around, the blocks randomly disappear if I look in certain directions...

When they disappear, the bounding box vanishes too, so I can walk through it (if I stand on the block and look around, I'll just fall down when it vanishes)

 

Screenshots:

There's three blocks you can see here:

 

Then I look slightly to the left, and the right one vanishes!

    	else
    		setBlockBounds(0.0F, 0.25F, 0.0F, 0.125F, 0.75F, 1.0F);

}

}
}

 

 

The TileEntity is empty at the moment.

 

Any ideas?

 

 

Someone also told me to try using "GL11.glRotatef(((TileEntityBarrierEntity)tile).getRotationPivot()), 0.0F, 1.0F, 0.0F);" instead of the if statements I have for rotation, but they didn't go as far as to telling me how to use getRotationPivot so right now, that's useless for me. At any rate, removing the rotation code altogether doesn't fix the issue.

It's disappearing because your bounding box is outside the field of vision. Expand it to take up the whole entity (here is a helpful post.)

It's not at all I spent a bit of time lining up the bounding boxes perfectly with the models; It's the exact right size, so that can't be the issue or I'd never notice it...

Oh. Okay then. I have no idea.

 

Unless perhaps the bounding box is in the wrong place? But if you can bump into it, then I'm out of ideas.

[Flenix]

It may well be something in the bounding box actually.

 

I'd only tested it with the eclipse testing environment. I just compiled it all and put it in a real forge environment, and the vanishing bug stopped.

BUT, the bounding boxes are bugging out at the same time. When I look at them the black lines are in the right place, but if I move into the full block area, my character glitches out. Did you play minecraft in alpha/early beta? Remember when you jumped on a fence and it bugged? Same kind of thing.

 

 

Any ideas?

I believe, dont quote me on this, but it to do with the origin block placement of the tile entity, Thaumcraft has the issue with its scribing tools and i dont think it can be helped. The issue is when minecraft looks dfor blocks in view to render the origin block of the tile entity is not on the screen hence it srops rendering.

 

(this could be a load of rubbish but after looking through that is what i've found.)

I think a way to solve that is to modify the collision boxes, just like you did with the bounding boxes. There's a method in the block class that you can put in your block class,  but it's very messy.
