Textures change in hand but not in world?

[TLHPoE]

So I currently have this piece of code inside of my block:

 

@Override
public void randomDisplayTick(World par1World, int par2, int par3, int par4, Random par5Random) {
	if(blockIcon == icons[0]) {
		blockIcon = icons[1];
		return;
	}
	if(blockIcon == icons[1]) {
		blockIcon = icons[2];
		return;
	}
	if(blockIcon == icons[2]) {
		blockIcon = icons[3];
		return;
	}
	if(blockIcon == icons[3]) {
		blockIcon = icons[0];
		return;
	}
}

 

It only changes the texture when it is in my hand/inventory, not the world.

Use metadata instead.  Every random updateTick, increase the metadata by 1, then display an icon based on the metadata.

 

What you're doing now is not going to work, as the Block class is a singleton.

I think that might cause some more problems because my block uses meta data to determine which location it faces (vine)

It might, but at least you can fix those problems. Icons are only registered at the creation of a block, so it won't change in the world unless the block itself is changed.

If you want meta for direction and icon, use Bitwise operators.

 

Lets say the first 2 bits are direction, and the last 2 are icon.

 

Direction = Meta  >> 2

IconIndex = Meta & 3

Meta = Direction << 2 | IconIndex

So if Direction is 1 and IconIndex is 3 in Meta, it looks like:

0111

To get direction we shift the bits to the left 2 places.

0001 = 1

IconIndex is the last 2 bits so we AND the meta to 3 (0011)

0111 AND 0011 = 0011 = 3

 

Thats a quick run through, hope it made a little sense.

Oh, I'm an idiot...

 

 

I could just use the animated textures thing/feature.

I could just use the animated textures thing/feature.

 

Or you could do that.

Hi

 

The reason it was working in your hand but not the inventory is because the renderer doesn't read the block textures every frame, only when the blocks are changed.

 

In contrast, the inventory render updates every frame.

If you want your blocks to animate, you should use either tile animations like water/lava, or TileEntitySpecialRenderer.
