i'm a newbie at modding. So far, i have made simple blocks and items. I have not even coded in a single mob (i am trying to create a biome though). I want to make a biome in the end. But i don't know how to make a grass block for said biome. Does anyone know how to code in a custom Grass Block?

Odd. Try initializing it at declaration.

um. here's the thing..

i actually don't really know that much about java. (minimal understanding) i learned how to code specific blocks and items from youtube. so i have no idea what you mean by that.

on a side note: i tried loading the game. it did not crashed. i placed the Reverse Grass block and for some odd reason it begun to transform into Reverse Dirt blocks.

Ahh. Well then I shall give you the same advice everyone like you gets. Go learn Java and THEN come back. If you don't know what "initalization" means then you've never coded in your life and should go do that.

Who are you? Why have you brought me here? And why are there so many PewDiePie fanboys surrounding meeeeeeeee....... *falls into pit and dies*.

 

Also this. Check it out.

Also don't just copy the class wholesale.  That'll never work correctly and it will be impossible to debug unless you actually know what you're doing.

 

That said:

 

public static IIcon getIconSideOverlay()
   
        return MBlocks.Rgrass.field_149994_N;[ <------error. cannot be resolved or is not a field.]
    }

 

Did it occur to you to do this?

 

public static IIcon getIconSideOverlay()
   
        return this.field_149994_N;
    }

 

Magic!

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.
