Hi all,

 

If I want to check that a block of mine is being placed on top of a valid block and im building a list of these blocks and I want to include things like oreCopper, oreTin etc.. even if my mod doesnt implement these ores do I have to create a block and register it in the OreDict or can I add something else to the list that signifies oreCopper etc...

 

for example:

 

public static Object[] allowedBlocks = new Object[] {Block.oreCoal, Block.oreDiamond};

 

how would I add copper ore to that? or is there a better way of doing this?

You need to listen to ore dictionary events.

 

Here's how I did it:

 

public class EventHookOreRegistration {
@ForgeSubscribe
public void entityAttacked(OreDictionary.OreRegisterEvent event) {
	if(event.Name.indexOf("ore") >= 0 || event.Name.indexOf("gem") >= 0) {
		MapsBase.oreBlocks.add(event.Ore);
		//oreBlocks is defined in the base mod as a new ArrayList<ItemStack>();
	}
}
}

 

Also, use ArrayLists instead of static arrays, as then the array size is dynamic so you don't have to worry about making sure you have room for mods that load after yours (also, for blocks, use Block[] not Object[] if you're ever going to do it that way).
