I need for each block because I'm creating a separate class file? or done differently?

 

 

pleace help me.

Eh? No disrespect, but I don't understand a word of that

sorry.

 

for new block in my mod a new class file

It depends, in what way the blocks are different. If all these are just normal block with just another texture, footstepsound, id and name, than you can create just one new class. If one block should have a special property, then you should do a new class file especially for this block.

Well basically, this is a classfile of a normal block:

package Tutorial;

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;

public class TutorialBlock extends Block {

public TutorialBlock(int par1, int par2, Material par3Material) {
	super(par1, par2, par3Material);
}

@Override
public String getTextureFile() {
	return "/Tutorial/tutorial_texutre.png";
}

}

In your mainmodfile, you should write something like this:

public static Block tutorialBlock= new TutorialBlock(500, 0, Material.sand).setHardness(3.0F).setResistance(5.0F).setStepSound(Block.soundStoneFootstep).setBlockName("oreCopper");

Thank you very much
