Integration with other mods without being a dependency

Posted January 17, 201411 yr

Hi,

I was working on my mod, AddedCompat, when I decided to stop permanent IC2 dependency and just have integration. I did follow a tutorial and wrote this:

package addedcompat.integration;

import java.util.logging.Level;

import ic2.api.item.Items;
import net.minecraft.block.Block;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.item.crafting.CraftingManager;
import net.minecraftforge.oredict.ShapedOreRecipe;
import net.minecraftforge.oredict.ShapelessOreRecipe;
import addedcompat.common.AddedCompat;
import addedcompat.common.CraftingManagerTable;
import addedcompat.common.LogHelper;
import cpw.mods.fml.common.Loader;

public class IC2Integration  {
public static void isIC2Installed() {
	if(Loader.isModLoaded("IC2")) {
		try {
			LogHelper.log(Level.INFO, "IC2 integration initialised");
			ItemStack energyCrystal = Items.getItem("energyCrystal");
			ItemStack lapotronCrystal = Items.getItem("lapotronCrystal");
			ItemStack advancedCircuit = Items.getItem("advancedCircuit");
			ItemStack lapiDust = Items.getItem("lapiDust");
			ItemStack bronzeIngot = Items.getItem("bronzeIngot");

			CraftingManager.getInstance().getRecipeList().add(new ShapedOreRecipe((energyCrystal), new Object[] {
					"RRR",
					"RSR",
					"RRR", Character.valueOf('R'), Item.redstone, Character.valueOf('S'), new ItemStack(AddedCompat.metaItemCompat,1,0)
				}));

				CraftingManager.getInstance().getRecipeList().add(new ShapedOreRecipe((lapotronCrystal), new Object[] {
					"LAL",
					"LRL",
					"LAL", Character.valueOf('R'), new ItemStack(AddedCompat.metaItemCompat,1,1), Character.valueOf('A'), advancedCircuit, Character.valueOf('L'), lapiDust 
				}));

				CraftingManagerTable.getInstance().getRecipeList().add(new ShapelessOreRecipe((bronzeIngot), new Object[] {
					Block.cobblestone, Item.ingotIron
				}));

				CraftingManagerTable.getInstance().getRecipeList().add(new ShapelessOreRecipe(new ItemStack(Item.ingotIron), new Object[] {
						Block.cobblestone, bronzeIngot
				}));
		 }
		catch(Exception e) {
			LogHelper.log(Level.INFO, "IC2 integration not initialised");
			e.printStackTrace(System.err);
                        }
	}else{
	}
}
}

However, it doesn't seem to work.

Thanks!

How about you put that into your base class into PostInit?

Reason is, I don't see it being called anywhere, unless you show us your base class.

Add to the dependency so you mod is loaded after IC2 maybe, you have not put up your main mod file so I don't know if you have done that already.

Oh, it is called anywhere. How would I do this?

Add to the dependency so you mod is loaded after IC2 maybe, you have not put up your main mod file so I don't know if you have done that already.

It is loaded after IC2, in dependencies it says after:IC2

I'm pretty sure that if you directly access the IC2 API it becomes a required dependency. Use reflection instead.

If you use any form of non-API checks to see if a mod is loaded before you call the API then it's not.

https://github.com/Draco18s/Artifacts/blob/master/draco18s/artifacts/worldgen/PlaceTraps.java

Check line 251.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

What's reflection? How do I use it?

So how would I do this with IC2? Like maybe Class.forName("ic2.api.item.Items"); ?

You can use Loader.isModLoaded("IC2") in place of that reflection call.

I wasn't aware of the Forge method when I did that.

Reflection is a soft dependency tool, its package is: java.lang.reflect.

The main methods you are likely to use are:

Class.forName(String)//load a class object from its path
Class#getMethod(String, Class...)//get a method object from the class object, with name and parameters
Method#invoke(Object, Object...)//call the method from the class object, with given parameters

See an example here.
