Generate plant near a certain block only

[microjunk]

I have a plant that I want generated in the swamps, I did that part, but I only want it to spawn near or within 2 blocks of water. I have a different plant that is using this code

 

 

 

public void randomDisplayTick(World world, int i, int j, int k, Random random)
        {
        	int dist=2;
            boolean isblocknear=false;
            for (int x0 = -dist; x0 <= dist; ++x0)
            {
            	for (int y0 = -dist; y0 <= dist; ++y0)
            	{
            		for (int z0 = -dist; z0 <= dist; ++z0)
            		{
            			if(world.getBlockId(i + x0, j + y0, k + z0)==MTJT.lovePlant.blockID && (x0!=0 || y0!=0 || z0!=0))
            			{
            				isblocknear=true;
            				world.spawnParticle("heart", i+0.5, j+1.0, k+0.5, 0.0D, 0.08D, 0.0D);
            				break;
            			}
            		}
            		if(isblocknear)
                    break;
            		}
            		if(isblocknear)
                    break;
            	} 
        			
        	}

 

 

 

This code will allow the plant if generated near another plant of the same type to spawn particles. It works great, but when applying this code to my other plant, it crashes the game...of course I changed the random display tick to on block added, and the Block love plant to the block waterstill. But this code is not working for the purpose I need.....Any help is appreciated

well first of all the three breaks is unnecessary

 

label0:
for(...
for(....
for(....)
if(....)
break label0;

 

also post the crash report please[/code]

Well, I figured out it was crashing because of the else statement I had after this

 

if(world.getBlockId(i + x0, j + y0, k + z0)==MTJT.lovePlant.blockID && (x0!=0 || y0!=0 || z0!=0))
            			{
            				isblocknear=true;
            				world.spawnParticle("heart", i+0.5, j+1.0, k+0.5, 0.0D, 0.08D, 0.0D);
            				break;
            			}

 

saying basically if it is not water than dont generate. I had removed the crash reports after this had stopped crashing when I removed it. I also found a method in the block class that may be of use, canPlaceBlockAt, not sure how I would modify this code I have or use the method properly. I also removed the breaks and it still spawns everywhere but where I want it to...

You might want to look at the existing plant code.  IIRC there's already a "nearby water" detection loop for spawning reeds.
