Hey,

 

I made a mod with 2 custom simple blocks, but i was thinking how can i make that for example Block numer 2 can only be placed on Block numer 1 and on no other block. I am also interested how can i make a chat message for the block breaker for example when player break a Block number 2 it will show a message on the chat only for the breaker 'Hey its me' ??

 

Sorry for my English.

Ohh thanks. Solved

I know also there is a method in command block "canPlaceON" or something like that. Where can i find that?

This will work if the position indeed needs to be corrected with an offset, otherwise remove that part.

 

@Override  // In Block 2
public boolean canPlaceBlockAt(World worldIn, BlockPos pos) 
{
     // Block block1 = new Block1();
     if (worldIn.getBlockState(pos.offset(EnumFacing.DOWN)).getBlock().equals(block1))
     {
          return true;
     }
     else return false;
}

Yee i know, it work, but i am interested where can i read about canPlaceOn method

A method like that does not exist in Block, however you can take a look at ItemStack#canPlaceOn. I've never used it so I am unsure about what exactly does it do but I believe it's worth to take a look.
