I have quite a few mod ideas, some pretty basic and some rather complicated. I'll share one of my first mod ideas here. And, tbh I'm surprised that noone has made it yet.
It's pretty simple:
It being MINEcraft, why not have a miner's helmet? You know those kind that are basically a hardhat with a little halogen lamp on them. So it lights up in front of the player's head like a torch but extending just 180 degrees forward. Now I know some people, including myself, like to use torches as breadcrumbs to navigate their way through a cave system, find their way back to where they came from, keep monsters from spawning, etc. But sometimes it can be tedious when you run out of torches/wood/coal and there's still tons more ores to get. And for those who play with portal gun there's really no need to leave a trail of torches to find your way out of a cave. Frequently I find myself just digging a stairway up if I have to anyways.
I thought it would fit in great as an IC2 addon, so that it used eu to charge the lamp, and the luminator as part of the recipe. Equipped with a batpack/lappack it would use the eu from that as well. And even use the paint from IC2 to change the color of the helmet. So I got mcp (minecraft coder pack) and eclipse (java software) and realized it's not so simple to make for one who is new to making a mod and also new to java, to have the light levels constantly change syncronized with the players movement. Perhaps an experienced coder can take this and run with it.
