How does i generate blocks on top of the surface world (like flowers)?


Recommended Posts

Hello, I was wondering how i could generate some bushes on top of the surface.

Does anyone know what i need to do?



This is for spawning ores, but it will only spawn blocks in other blocks like 'MagneziumOre generate in the Stone' but i wanted to have like 'Strawberry plant generate on top of the grass block'.




Thanks! ;)

Using the ore generator is not the best method here.  You're better off picking an X and Z location inside a chunk and then finding the surface block and populating that way.


I use this function, which has a few extra bits, but does what you need.


/*Places a random collection of blocks (flowers) at a random distance from a given spot on the surface
* Paramters:
* x/y/z - location on the surface
* block and meta
* radius is the maximum distance away to spawn at
* num is how many blocks to attempt to place
* cluster radius is how close (or far) the blocks will be placed
    public static void scatterFlowers(World world, int x, int y, int z, Block b, int meta, int radius, int num, int clusterRadius) {
    	Random r = new Random();
    	float[] u = RandomInUnitCircle(r); //find a location inside a unit circle, this value is multiplied by the radius.
    	int fails = 0;
    	int j, k, l;
    	while(num > 0 && fails < 20) {
    		j = x + r.nextInt(clusterRadius) - (clusterRadius/2) + Math.round(u[0]*radius); //random point inside the cluster radius, plus the offset for the large circle
    		k = y-5; //check up and down a few blocks
    		l = z + r.nextInt(clusterRadius) - (clusterRadius/2) + Math.round(u[1]*radius); //random point inside the cluster radius, plus the offset for the large circle
    		for(int f=0; f+k <= y+5; f++) {
			if(world.getBlock(j, f+k, l) == Blocks.grass && (world.getBlock(j, f+k+1, l) == Blocks.air || world.getBlock(j, f+k+1, l) == Blocks.tallgrass)) { //place above grass and replace tall grass
				world.setBlock(j, f+k+1, l, b, meta, 3);
				k = 100;

    public static float[] RandomInUnitCircle(Random rn) {
    	float t = (float)Math.PI * (2*rn.nextFloat());
	float u = rn.nextFloat()+rn.nextFloat();
	float r = (u>1)?2-u:u;

    	return new float[] {r*(float)Math.cos(t), r*(float)Math.sin(t)};


I call this function after I've found a point on the surface, e.g.:


//from an X/Y/Z location, go up until we find the surface
for(int j=1; y+j < 90; j++) {
	if(world.getBlock(x, y+j, z) == Blocks.grass) {
		MainMod.scatterFlowers(world, x, y+j+1, z, OresBase.blockOreFlowers, 0, 25, 8, 11);

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.

    • Crash with the error: The game crashed whilst exception ticking world Error: java.util.ConcurrentModificationException pastebin crashlog the game worked for like 24h, then started to receive this error. Things I've tried: removing optifine or other performace mods. tried different versions (older) of the pack. set true to remove error entities and tiles in forge.cfg asked for help on the sevtech github, they said its fixed, its not. tried a different pc and still crashed happened only one time on another map although i cant make it happen again on that map.

    • I am in such a mess. I have lost over 4.7m due to a scammer... It started as bank wires and then bitcoin. it is hard to imagine but it is true and can send any proof, then I tried to use a couple of recovery companies and was as well. Graphic design has been more than just a hobby for me since high school—it has become a thriving career. Starting in my parents' garage, I eventually expanded to my office, running a successful graphic design business. However, like many, I faced the need to diversify my investments due to inflation. This led me to invest 60.16 in Bitcoin, a decision that paid off handsomely as my investment grew to 4.7m over time. This financial windfall allowed me to upgrade my equipment and take on more ambitious projects, furthering the growth of my business. Unfortunately, my excitement was abruptly cut short when I fell victim to a hacking incident. Malware infected my computer, giving hackers access to my Bitcoin wallet. The devastation of potentially losing all my hard-earned savings and plans weighed heavily on me. At this dire moment, a fellow designer suggested Linux Cyber Security Company as a potential solution. Desperate for a lifeline, I reached out to them, hoping for a miracle. The response from Linux Cyber Security Company was prompt, incredibly professional, and effective. Their team quickly traced the hacker’s activities and recovered most of my funds, alleviating a significant amount of stress and uncertainty. Beyond the recovery, they took the time to educate me on essential practices to secure my Bitcoin holdings better. They emphasized using antivirus software to prevent malware infections, avoiding suspicious downloads, and the added security provided by hardware wallets. This experience served as a critical wake-up call for me. It highlighted the vulnerabilities inherent in digital assets and underscored the importance of robust security measures. Thanks to the guidance and expertise of Linux Cyber Security Company, I now feel more equipped to protect my digital assets proactively. Their insights have empowered me to implement stronger security protocols in my business operations and personal finances alike. With my Bitcoin funds securely recovered and a newfound understanding of digital security best practices, I am more confident in navigating future challenges. This journey has reinforced my commitment to safeguarding my hard-earned assets and leveraging technology responsibly. I am optimistic about the growth opportunities ahead, creatively in graphic design and prudently in investment strategies. In conclusion, while the hacking incident was a setback, it ultimately became a catalyst for enhancing my digital security awareness and resilience. I am grateful to Linux Cyber Security Company for their expertise and support during a challenging time, enabling me to continue pursuing my passion for graphic design with renewed confidence and financial stability.
