ellipsis

I have some code using ASM that can replace methods in classes that aren't statically initialized, but I'm having trouble replacing Block methods, since it's statically initialized. Can I either reload all classes by recreating the Forge RelaunchClassLoader or plug my custom IClassTransformer into the RelaunchClassLoader before the vanilla classes are loaded? EDIT: I fixed the problem by making a core mod to handle hooking and then injecting proxy calls to the needed methods.

What should I implement instead of IInventory?

I'm using the latest version of Forge and I get a crash when I try to run my mod outside of MCP. Here's the crash log: ---- Minecraft Crash Report ---- // I let you down.

I'm making a mod that includes chemistry (among other things), and I have a test tube item. I'm using addInformation to add the amount and some other info, but Minecraft's built in font renderer doesn't support subscripts, which I want to use to draw the chemical formula. I don't want to modify GuiContainer, so a hook for item tooltip rendering would be really useful. This could be implemented by adding an interface "IItemTooltipRenderer", then doing a check in GuiContainer.drawScreen to see if the item is an instance of IItemTooltipRenderer and calling the item's rendering logic instead of the standard logic. EDIT: Apparently Unicode subscript characters work, but this would still be useful to render icons representing element properties (radiation, acid, flammable, etc)
