Hiya. I've been toying with mods for a while, and I noticed something:

While forge does allow for ores to be used in the same manner, it does not allow this for ingots. For instance:

If you use 2 Industrial Craft Copper ingots, and 1 RedPower copper ingot, and 1 piece of tin from either, it will not create bronze.

If the directory was extended to use ingots as well, than all the problems about not being able to use ingots from different mods with each other would be resolved.

Along with this, I have noticed that mods that have their own energy system are also not compatible. You need to use the correct type of energy for each mod.

This could also be resolved by adding a universal energy system.

Now, if a modder wants to have their own unique energy, then they can use a class to make their own kind of energy. This could be used for stuff like EE2 and the like.

This way, things like industrial craft generators could power redstone sorting machines and similar situations.

How does this sound?

The ingots is a modder issue, Forge provides all functionality that modders need, it's up to them to use it.

As for the energy system, once again, modders need to work on it. Not us, there is already a project for it lower down in the forums.
