When I put a partially transparent texture on a block, the texture is transparent

public class BlockBouncy extends Block {
public BlockBouncy() {
	super(Material.rock);
	this.setBlockName("bouncy");
	this.setBlockTextureName(RP4KMod.MODID + ":" + this.getUnlocalizedName().substring(5));
	this.setStepSound(soundTypeStone);
	this.setCreativeTab(CreativeTabs.tabBlock);
	this.setHardness(3.0f);
	this.setResistance(5.0f);
}	

@Override
public void onEntityWalking(World world, int p_149724_2_, int p_149724_3_, int p_149724_4_, Entity entity) {
	entity.motionY+=2;
}
public boolean isOpaqueCube() {
	return false;
}
}

public int getRenderBlockPass()

    {

        return 1;

    }

Yay, that works

And it's not laggy as the top block of a biome
