[1.7.2] I want right click blockchest during the sneak.

Steps you need to take in this order:

1) learn proler english. That is, not using google translate ro literally translate it and copy it down on this forum. If you don't know english, you are gonna have a bad time.

2) learn Java. Minecraft is made in Java and without Java knowledge, you can't make mods.

3) start with a basic Block and Item, and get familiar with the Minecraft code.

4) get more familiar with the Forge and Minecraft code. Know what you should do when a certain problem arises, e.g. if you have to deal with events, know how you should handle events.

5) then, do not come to these forums saying you want something, and expect people to write it for you. Try yourself, Google around, and if you have a problem, or need a suggestion to start, make a topic on the right board, and wait for people to help.

@Kloonder, you shouldn't have to write arabic or something just so he can understand, it sounds the same like his english sounds to us. Also, he's the one that should learn proper English.
