[1.7] Getting Texture from Block and put it on an other Block.


Fyreek

Recommended Posts

Hello There,

I am very new to modding. I am having a problem with one of my Items.

When i click on the ground with it, it switches the block i am looking at with a block i made.

Now the Problem is how to get the Texture of the block that was there and apply it to my own Block, so that my Block looks like the Block that was there before.

I already now hot to get which block was there before, but i cant figure out how to know which texture it uses and how to apply the new texture to my Block.

Is that even possible?

Would be nice if someone could answer that.

 

Fyreek.

You would need a TileEntity, saving the block instance which should be shown in there and in your blocks getBlockTexture method, grab the TileEntity, get the block from it and get the Icon from this block via blockInstance.getIcon()

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.

I don't know which Block/Item should be a TileEntity.

Should the item be it? Because i right click with it? Or the Block that that will be on the Position of the Block i replace?

 

Also i dont know how to save the blocks instance. I searched a bit but cant find anything that would help me.

Blocks do not have instances in the world.  They're simply a giant array of integers (and associated metadata).  In order to have more complex behavior than "I am block ID 5!" you need a TileEntity.

 

Chests, furnaces, brewing stands, and so on are all tile entity blocks.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

DO NOT PM ME WITH PROBLEMS. No help will be given.

So i tried a few things but couldnt get it to work. i tried saving the Block in the TileEntity and then getting the BLocks Texture through the Tile Entity, but my game wont load up any more. I think i am doing it copletly wrong but i dont know what to do at the moment.

BlockRedTileEntity.class:

 

public class BlockRedTileEntity extends TileEntity{

public static Block BlockStored;

public boolean onBlockActivated(World world, int xPos, int yPos, int zPos, EntityPlayer player, int par6, float par7, float par8, float par9){

	if(!world.isRemote){
		System.out.println("TileEntity onBlockActivated: " + world.getTileEntity(xPos, yPos, zPos));
		if(player.getCurrentEquippedItem() != null){
			//System.out.println("Hand nicht leer");
			if(player.getCurrentEquippedItem().getItem() == new ItemStack(Blocks.grass).getItem()){
				System.out.println("Grass");
				BlockStored = Blocks.grass;
			}
		}
	}

	return true;
}

 

 

BlockRed.class:

 

public class BlockRed extends BlockContainer {

public BlockRed() {
	super(Material.ground);
	this.setBlockTextureName(BlockRedTileEntity.BlockStored.getBlockTextureFromSide(0).toString());
}

 

 

I hope you can help me.

1. I know what static means, but if i have it not static the line

this.setBlockTextureName(BlockRedTileEntity.BlockStored.getBlockTextureFromSide(0).toString());

is not working, because it needs a static reference.

 

2. If i right click the Block it works, so i think that shoudl be right

 

3. Thats not my Problem atm. i first want to try to get it to work, so that it changes textures. But that is not working.

Saving and Loading i want to do later.

    • { "type": "magic_overhaul:rune_inscribing", "base": { "item": "//base item" }, "template": { "item": "//template item" }, "output": { "count": 1, "item": "//output item" } } ^ Ok, where is your recipe JSON placed in your file structure? What's it called? And paste the actual JSON you're testing with, because it needs to be valid.
