Now i'm stuck because i can not find a Forge Event that is fired when the player selects an item in the hotbar . Going through net.minecraftforge.event.* it seems like such an event doesn't exist. Can somebody help, maybe describing a workaround for my intention?

Ok thank you very much! You seem to know how that works, but that was a really short explaination . The only way adding item textures that i know is new Item().setTextureName("ID:Name"). How is MapItemRenderer to be used, when i have an Item object and nothing else? Furthermore i actually only need *text*, that is updated in certain time intervals and write it onto that texture. Realizing that using a RGB array might be overkill.. Is there maybe a more specific method?

Thank you. But trawling through unexplained foreign code can get very tedious.. Does somebody maybe know any related tutorial?

My goal is to have something like a tablet computer in minecraft. Similar as the map (http://minecraft.gamepedia.com/Map) it should change its texture dynamically. The screen should show information like found in the debug screen [F3]. (Yes, it would be superfluous, but much more pretty in my opinion.) By way of illustration: https://dl.dropboxusercontent.com/u/43694603/tablet.png How can i bring ever-changing content (text...) on an item's texture?
