#loader contenttweaker

import mods.contenttweaker.VanillaFactory;
import mods.contenttweaker.Block;

var antiIceBlock = VanillaFactory.createBlock("anti_ice", <blockmaterial:ice>);
antiIceBlock.setLightOpacity(3);
antiIceBlock.setLightValue(0);
antiIceBlock.setBlockHardness(5.0);
antiIceBlock.setBlockResistance(5.0);
antiIceBlock.setToolClass("pickaxe");
antiIceBlock.setToolLevel(0);

antiIceBlock.setSlipperiness(0.3);
antiIceBlock.register();

You will need to add tile.contenttweaker.blockName.name=Localized Name to the responding language files.
If you have doubts, take a look at the display name of the item when you're holding it before translating it.

Alternatively, you could use CraftTweaker's localization feature, though it's recommended using the language files!
