[1.7.2]New to mods a few questions

Recommended Posts

Hi guys this is my first time making a mod and i wanted to start simple so i have added an ore that generates and smelts into an ingot i have also added a recipe for a pick.

 

Now i want to make this pick do "more" when it busts the block maybe take the surrounding blocks or just the block at the players feet if there picking at head height. i know i would need to do this in a block-update of sorts so any info on this would be nice

 

also if you could tell me how i would go about replacing the blocks around the "updated block" with air that would also be nice

 

thnx in advance

OG

You can do this by overriding the onBlockStartBreak() method in your pick class this is called just before the block breaks. There is a bit involved in getting it to work properly but instead of trying to explain it and completely confusing you (im not good at explaining things) i have put together an example pick class that will dig a 3x3x3 area around the block you mine. Hopefully you will be able to figure out how it works and modify it to suit your needs.

 

You shouldnt have any trouble getting this class to work all you have to do is rename the package and add it in your main class preinit method (or wherever you add your items) using

 

testPick = new TestPick();

 

It will be in the creative tools tab and it will have the diamond pick texture.

If you need me to explain anything just ask.

 

Oh and i will just point out that i am also very new to modding so there may be better ways to do some of this.

 

Edit: Also note this tool wont loose durability because i copied most of the code from one of my tool classes and my tools have infinite durability. If you cant figure out how to make the tool loose durability when you use it let me know.
