To create an explosion, the following method signatures may be used:
boolean createExplosion(double x, double y, double z, float power); boolean createExplosion(double x, double y, double z, float power, boolean setFire); boolean createExplosion(double x, double y, double z, float power, boolean setFire, boolean breakBlocks); boolean createExplosion(Location loc, float power); boolean createExplosion(Location loc, float power, boolean setFire);
Simulating a TnT explosion that break blocks and set fire at x=0, y=0 and z=0
createExplosion(0.0, 0.0, 0.0, 4F, true, true);
The following methods can be used to drop an Item somewhere in the world:
Item dropItem(Location loc, ItemStack is); Item dropItemNaturally(Location loc, ItemStack is);
dropItem means dropping an Item exactly at the location, returning an Item object.
dropItemNaturally means dropping the Item at the location, but with a random offset, meaning it won't be exactly at the location, but very close nearby. This is made to simulate an item being dropped by an entity or a block such as a Dispenser.
The following methods can be used to generate a tree naturally (as if it was grown from a sapling) into the world.
boolean generateTree(Location loc, TreeType type); boolean generateTree(Location loc, TreeType type, BlockChangeDelegate delegate);
|BIG_TREE||Regular tree, extra tall with branches|
|BROWN_MUSHROOM||Big brown mushroom; tall and umbrella-like|
|CHORUS_PLANT||Large plant native to The End|
|COCOA_TREE||Jungle tree with cocoa plants; 1 block wide|
|DARK_OAK||Dark Oak tree.|
|JUNGLE||Standard jungle tree; 4 blocks wide and tall|
|JUNGLE_BUSH||Small bush that grows in the jungle|
|MEGA_REDWOOD||Mega redwood tree; 4 blocks wide and tall|
|RED_MUSHROOM||Big red mushroom; short and fat|
|REDWOOD||Redwood tree, shaped like a pine tree|
|SMALL_JUNGLE||Smaller jungle tree; 1 block wide|
|SWAMP||Swamp tree (regular with vines on the side)|
|TALL_BIRCH||Tall birch tree|
|TALL_REDWOD||Tall redwood tree with just a few leaves at the top|
|TREE||Regular tree, no branches|
Both signatures will return true if the tree was sucessfully generated, false otherwise.
There are some spawning rules in Worlds in Bukkit. They are:
Animal spawning can be split into the following categories:
To get the amount of animals that can be spawned inside the World at runtime, you can use the method
For land animals and
For water animals.
Both limits can be set with the methods
void setAnimalSpawnLimit(int limit); void setWaterAnimalSpawnLimit(int limit);
Note: If set to numbers below 0, world's default amount will be used instead.
Minecraft makes an attempt to spawn animals every 400 ticks (default). That can be changed if you desire, using the following signatures:
void setTicksPerAnimalSpawns(int ticks); void setTicksPerWaterAnimalSpawns(int ticks);
Note: If set to 0, animal spawning will be disabled for this world. It's recommended to use setSpawnFlags(boolean, boolean) to control this instead.
