Hi Everyone, this is my first mod for minecraft so I am still learning, thus any help would be greatly appreciated. I am trying to have an item set the blocks underneath or around it on fire when it is dropped on the ground, but I am not sure how I should go about this. My initial thought was to find the entity in the world and then use its world coordinates and SetBlock() to accomplish this. However I couldn't find a way to find the entity in the world.

 

Is this the best way to go about this? And if so, how would I go about finding the entity in the world.

 

All replies would be greatly appreciated.

 

Thanks, OfficialPiAddict.

Override

Item#onEntityItemUpdate

. This is called once per tick by every

EntityItem

containing an

ItemStack

of your

Item

.

 

In your override of this method, check that the entity is on the ground (its

onGround

field is

true

), the block at the entity's position isn't fire and fire can be placed at the entity's position (

Block#canPlaceBlockAt

returned

true

). If this condition is met, set the block at the entity's position to fire.

 

In 1.7.10, use

World#getBlock

and

World#setBlock

to get and set the

Block

at the specified position. Use the

posX

,

posY

and

posZ

fields of

Entity

to get an entity's position and

MathHelper.floor_double

to convert them to integers.

 

In 1.8.x, use

World#getBlockState

and

World#setBlockState

to get and set the

IBlockState

at the specified position. Use

IBlockState#getBlock

to get the state's

Block

. Use the

BlockPos(Entity)

constructor to get an entity's position as a

BlockPos

.

In addition to the above comment, I'd take a look into the flint and steel's code to see how it sets stuff on fire. I believe World has a method like setBlockOnFire, which also plays the sound effect.

Also, if this isn't your own custom item you're working with, you may need to look into event handling, which there are plenty of tutorials for.

Hi,

 

Thanks to both of you for the quick replies. I have it working now, so thanks. Its greatly appreciated.
