[1.7.10] Changing vanilla tools properties without editing base code

[cw84]

As the title says... I am looking for a way to change vanilla tools properties without editing the base code.

I tried using reflection, but it appears I've done nothing:

import net.minecraft.item.Item.ToolMaterial;
import cpw.mods.fml.relauncher.ReflectionHelper;

public class ModVanilla
{
public static void changeSettings()
{
	// Adjusting Gold Tools
	ReflectionHelper.setPrivateValue(ToolMaterial.class, ToolMaterial.GOLD, 2, 5);
	ReflectionHelper.setPrivateValue(ToolMaterial.class, ToolMaterial.GOLD, 750, 6);
	ReflectionHelper.setPrivateValue(ToolMaterial.class, ToolMaterial.GOLD, 8.0F, 7);
	ReflectionHelper.setPrivateValue(ToolMaterial.class, ToolMaterial.GOLD, 2.5F, ;
	ReflectionHelper.setPrivateValue(ToolMaterial.class, ToolMaterial.GOLD, 10, 9);

	// Adjusting Diamond Tools
	ReflectionHelper.setPrivateValue(ToolMaterial.class, ToolMaterial.EMERALD, 10.0F, 7);

	// Adjusting Stone Tools
	ReflectionHelper.setPrivateValue(ToolMaterial.class, ToolMaterial.STONE, 14, 9);

	// Adjusting Iron Tools
	ReflectionHelper.setPrivateValue(ToolMaterial.class, ToolMaterial.IRON, 12, 9);
}
}

 

Any help here would be great! Thanks guys...

Try using the version of

ReflectionHelper.setPrivateVersion()

which accepts a String, instead of a number, so you can just specify the field name instead of the index.

So technically, this code is correct and should be working? I only ask because while it doesn't appear to crash the game, it also doesn't appear to be changing any values. I feel maybe there is more to the puzzle than this? I am calling this class in my main last (prior to an event listener).

All you need:

    @EventHandler
    public void postInit(FMLPostInitializationEvent event)
    {
     changeSettings()
    }

I can't seem to get this to work...

I've done what Lewie suggested: added my changeSettings() to FMLPostInitializationEvent.... previously I had it in my FMLInitializationEvent.

- No Luck -

 

I've done what larsgerrits suggested and used the string version... unfortunately I'm not sure I'm using it correctly because when I tried something like:

ReflectionHelper.setPrivateValue(ToolMaterial.class, ToolMaterial.GOLD, 750, "maxUses");

It just simply crashes on loading Minecraft.

 

I found this post: http://www.minecraftforum.net/forums/mapping-and-modding/mapping-and-modding-tutorials/2151027-1-7-x-using-reflection-to-modify-vanilla-values

And this is where I've been basing my changes off of. Though, apparently, I am not doing things correctly.

 

What am I doing wrong here?

Changing the ToolMaterials values won't get you much, because:

1. they're final, you need some reflection black magic to actually change the value (removing the final modifier of maxUses and set the value)

2. Your mod gets initialized after the vanilla stuff, so even if you edit the value, the max damage of the items was already set using the original value (I've tried it)

 

So if you really need to change the golds max uses, I suggest you go either coremod and change the value of the material before any items get initialized or change the tool materials value as well as all the items max damage values.

I copied your code, put changeSettings() in PostInit and I did a quick test to mine diamond with a gold pick - it worked.

[cw84]

You're right. The tool harvest level did change. Appears I had to do something like Item.gold_pickaxe.setMaxDamage(int) to change the max uses of the item. I believe this answers why:

2. Your mod gets initialized after the vanilla stuff, so even if you edit the value, the max damage of the items was already set using the original value (I've tried it)

 

So if you really need to change the golds max uses, I suggest you go either coremod and change the value of the material before any items get initialized or change the tool materials value as well as all the items max damage values.

 

Thanks for all the help and insight on this guy's!
