[1.8.9] Overriding Vanilla Block Properties

[drok0920]

I'm trying to make a mod that changes the properties of vanilla blocks.  I would like to replace them with my own class if possible or at least change thier harvest level.  I have read the solution here: http://www.minecraftforge.net/forum/index.php?topic=7866.0 but it doesnt seem to work any more and the only other solution i have found use reflection or some similar method to achieve it.

 

Thanks

I am not sure it will work in 1.8.9 but it works in 1.7.10

If you know, there is list of blocks.

Like Blocks.sand

If you pick up your block for modifying, then use some basic methods from Block class.

 

Example

Block b = Blocks.sand;
b.setHardness(6.0F) //Sets a hardness for given block
b.setTextureName(.......) //Sets texture for block.
b.setHarvestLevel("pickaxe", 3) //Sets harvest level for block.

And so on...

If I am wrong with this, simply write a reply or PM me.

I'm not sure if it works with blocks, but I did smth like this

public static final void init() {
    	
        Items.diamond_sword.setMaxDamage(500);
        Items.diamond_sword.setTextureName(Main.MODID + ":itemSwordSuperIron");
        Items.diamond_sword.setUnlocalizedName("itemSwordSuperIron");

Do note that a harvest level of 0 (wood tools) is not sufficient to prevent blocks from being dropped when mined by hand.

Sorry if this is stupid question.

But Hand = harvest level -1?

I can't believe i didnt think of doing that thank you!  However i would still like to know if there is a way to override it with my own class/add a tile entity to the block.

[Enginecrafter]

Oh thanks. I am happy too I finally helped someone.

[Enginecrafter]

Try something like this

 

Main class

Blocks.sand = new BlockCustomizedSand()

 

Customized block class

public class BlockCustomizedSand extends BlockSand
{
     @Override
     Override methods you want
}

The substitution alias system (

GameRegistry.addSubstitutionAlias

) is supposed to allow this, but I haven't had much luck with it myself.

Hand doesn't have a harvest level.  There's simply a check to see if the player is allowed to harvest a material without needing a tool.  If so, the block is always harvested, regardless of how the player broke it (hand, wrong tool, correct tool, or with a random item), and is harvested with a x5 speed bonus (this is why it takes so long to break stone by hand, even though Stone and Wood have the same hardness).

 

Setting the harvest level to 0 (or higher) is for the tool-speed-multiplier lookup.  This is why digging with a wooden shovel is faster than by hand but not by much: dirt can already be harvested by hand and already benefits from the "can harvest: x5 speed" bonus, whereas using a wooden shovel adds another x2 (taking it from 0.9 seconds to 0.45 per block).

Ok so i tried just using

Items.wooden_pickaxe = flint_pickaxe;

to override the class it uses with no success.  It gives an error: "The final field Items.wooden_pickaxe cannot be assigned". I know this means it cannot be assigned to so is there a better way to do this?

[Enginecrafter]

The field cannot be assigned because these fields are final but I will try to find anither way to do this.

The field cannot be assigned because these fields are final but I will try to find another way to do this.

Reflection? Can a final field be brute-forced?

(Probably bad style for anything shared beyond your own server and friends, somewhat like a core mod)
