 * Color added to make reading easier.


 * Arguments


 * effect (BE: effect: string)
 * Specifies the particle to create. Must be a particle name (for example, ).


 * requires 4 color channel parameters to be set along with the name, representing red, green, blue and alpha, each being a value in the range 0 to 1. For example:   creates a pink particle at full opacity.


 * and  require a block and an optional state as a parameter. For example:


 * requires an item name as a parameter. For example:


 * pos (BE: position: x y z ) (optional)
 * Specifies the position at which to create the particle. All values (including y) must be between -30,000,000 and 30,000,000 (inclusive, without the commas). May use tilde notation to specify a position relative to the command's execution.


 * delta (BE: size: x y z ) (optional)
 * Specifies the size of the 3-dimensional cuboid volume to spawn particles in, centered on position pos, and divided by about 8 (using  specifies a cuboid of about 8×8×8 in size)


 * Exception 1: When name is  or , a  of 0 will cause the delta and   to act like RGBE values instead, ranging from 0.0 to 1.0.
 * Exception 2: When  is set to 0, the delta will instead act as motion values for the particle. ,   and   will instead become  ,   and   respectively.
 * Exception 3: When name is,  , or   and speed is not 0, and count is 0 or not specified, these values are set as the RGB channel values of the color of the particle, and are specified in the range 0 to 1.  In this usage, the speed parameter acts as a multiplier on these values.  If count is greater than 0 for those particles, delta are treated as a 3-dimensional volume as usual, rather than as a color, and randomized colors are used.
 * With  or ,   produces a black particle for example,   produces a green particle, and   produces a dark blue particle, etc.
 * The  particle's RGB channels behaves differently:
 * With  or ,   produces a black particle for example,   produces a green particle, and   produces a dark blue particle, etc.
 * The  particle's RGB channels behaves differently:


 * The other peculiarities are explained by this pseudocode:

! Pseudocode Set Red = xd, Green = yd, Blue = zd Multiply each (Red, Green, Blue) by speed If Red = 0 then set Red = 1 Set AllChannelMultiplier = RandomBetween(0.6, 1.0) For each channel (Red, Green, Blue): ## Multiply (so that we step towards the range of a Byte) Multiply channel by 256 ## Randomize (note that this causes a triangular distribution ## such that 0.74 is the mean net multiplier) Multiply channel by RandomBetween(0.8, 1.0) Multiply channel by AllChannelMultiplier ## Convert (to an actual Byte value) Round channel toward zero, to the nearest integer Set channel = channel Mod 256 Return color of this particle as (Red, Green, Blue)
 * }
 * To better illustrate this process, consider these particular values, which can be used for any of xd yd zd to affect their respective channels (with the exception of xd = Red = ).

 * Multipliers have no effect, so the channel will stay at . Note that this is not possible for the red channel.

 * Since every possible value is less than, this channel will have a true bit value of  , even for the red channel. This is true for any input value that has an absolute value of less than.

This results in a some particles with bit   and some with bit   (i.e., some dark and some bright). Values closer to zero produce more dark particles, and values further from zero produce more bright particles.

 * speed (BE: speed: float) (optional)
 * Specifies the speed of the particle. Must be at least 0. When name is, the speed modifier will instead change this particle's color (ranges between 0.0 and 1.0. 1.0 and higher will follow the same pattern as the color gradient as between 0.0 and 1.0).


 * count (BE: count: int) (optional)
 * Specifies the number of particle effects to create. Must be at least 0 (which produces one particle). If set to 0, the delta arguments will instead indicate the motion of the particle.  will instead become  respectively. Additionally, leaving this value at 0 will instead cause the delta and speed to act like RGBE values (respectively) for the particles   and   instead.


 * mode (optional)
 * Specifies the display mode:  or  . Setting   will allow the particle(s) to be seen up to 256 blocks away and by players that use the minimal particles setting.


 * player (optional)
 * Allows control of which player should view this particle instead of everyone in the viewing range of the particle.


 * params (optional)
 * Allows,  ,   and   to be modified to view a specific item or block. Two parameters are accepted for.


 * For,   and  , the params argument specifies a numeric ID (block only) and a data value, using a single number: id+(data×4096).


 * For, two params arguments specify the numeric id (block ID or item ID) and the data value separately.


 * Result


 * Fails if the arguments are not specified correctly.


 * On success, creates the specified particle.


 * Examples


 * To create a stationary huge explosion particle 10 blocks to the east:
