Modifying Existing Materials

All periodic table elements are present in GT, but some of them don't have any properties attached. You can also add a BlastProperty for EBF autogenerated recipes. You can also do this for other materials such as Obsidian. Here is how you can add them:

periodic_table_elements.js

    const $IngotProperty = Java.loadClass('com.gregtechceu.gtceu.api.data.chemical.material.properties.IngotProperty');
    const $DustProperty = Java.loadClass('com.gregtechceu.gtceu.api.data.chemical.material.properties.DustProperty');
    const $FluidProperty = Java.loadClass('com.gregtechceu.gtceu.api.data.chemical.material.properties.FluidProperty');
    const $BlastProperty = Java.loadClass('com.gregtechceu.gtceu.api.data.chemical.material.properties.BlastProperty')

    GTCEuStartupEvents.registry('gtceu:material', event => {

        // Ingot
        GTMaterials.Zirconium.setProperty(PropertyKey.INGOT, new $IngotProperty());
        GTMaterials.Obsidian.setProperty(PropertyKey.INGOT, new $IngotProperty());

        // Dust
        GTMaterials.Selenium.setProperty(PropertyKey.DUST, new $DustProperty());

        // Fluid
        GTMaterials.Iodine.setProperty(PropertyKey.FLUID, new $FluidProperty());
        GTMaterials.Iodine.getProperty(PropertyKey.FLUID).storage.enqueueRegistration(GTFluidStorageKeys.LIQUID, new GTFluidBuilder());
        GTMaterials.Oganesson.setProperty(PropertyKey.FLUID, new $FluidProperty());
        GTMaterials.Iodine.getProperty(PropertyKey.FLUID).storage.enqueueRegistration(GTFluidStorageKeys.GAS, new GTFluidBuilder()); //Can be LIQUID, GAS, PLASMA or MOLTEN

        // Blast Property
        GTMaterials.Zirconium.setProperty(PropertyKey.BLAST, new $BlastProperty(8000, 'higher', GTValues.VA(GTValues.MV), 8000));

    });

You can even add an ore to existing materials:

```js title="flags.js GTCEuStartupEvents.registry('gtceu:material', event => {

const $OreProperty = Java.loadClass('com.gregtechceu.gtceu.api.data.chemical.material.properties.OreProperty');

    //Zinc Ore
    GTMaterials.Zinc.setProperty(PropertyKey.ORE, new $OreProperty());

});

You can also add flags to existing materials:js title="flags.js GTCEuStartupEvents.registry('gtceu:material', event => { GTMaterials.Lead.addFlags(GTMaterialFlags.GENERATE_GEAR); //This is for materials already in GTCEU GTMaterials.get('custom_material_name').addFlags(GTMaterialFlags.GENERATE_FOIL); //This only works for materials added by GTCEU addons }); ```
