今年的海灯节没有烟花，比较遗憾，于是计划在MC中做一个烟花数据包，结果拖到了四月份（
演示
使用数据包提供的API函数，可以很方便地制作烟花，数据包提供多项可选参数以丰富烟花效果
详细参数说明见文章末尾
首先，通过设置不同的物理属性和条件限制，可以做出不同的抛物线扩散效果
这样做将会生成数条抛物线，数量由参数n控制
参数t控制每条抛物线的存在时间
mcfunction
function sklibs:skfirework/fx/spread {
config:{
yaw:[-50,-10],
pitch:[30, 80],
t: [20,60],
n: 60,
v: 0.5,
g: 0.04,
tick_cmdv:[{cmd:"particle flame ~ ~ ~ 0 0 0 0 1 force"}]
cmdv:[]
}
}v=0.5 g=0.01
v=0.5 g=0.04
v=0.5 g=0.04 yaw∈[-50,-10] pitch∈[30,80]
然后，让每一条抛物线在已存在时间减为0时生成firework
mcfunction
function sklibs:skfirework/fx/spread {
config:{
yaw:[-50,-10],
pitch:[30, 80],
t: [20,60],
n: 60,
v: 0.5,
g: 0.04,
tick_cmdv: [{cmd:"particle flame ~ ~ ~ 0 0 0 0 1 force"}],
cmdv: [{
cmd: "function sklibs:skfirework/fx/firework",
args:{
config:{
shape: 0,
colors: [{from:[I;13047173],to:[I;16761035]},{from:[I;16711680],to:[I;10824234]}],
n: 1
}
}
}]
}
}可以观察到上述命令添加了如下的参数 当抛物线已存在时间减为0时，将执行参数cmdv中的函数事件，调用sklibs:skfirework/fx/firework函数生成烟花，其中args是函数的参数
snbt
cmdv:[{
cmd:"function sklibs:skfirework/fx/firework",
args:{
config:{
shape:0,
colors:[{from: [I;13047173],to: [I;16761035]},{from: [I;16711680],to: [I;10824234]}],
n:1
}
}
}]效果如图所示
此时，我们的烟花会在命令执行瞬间爆炸，但是烟花应该上升一段距离才会爆炸，使用launch函数控制烟花的延时
mcfunction
function sklibs:skfirework/fx/launch {
config: {
life: 50,
cmdv: [
{
cmd: "function sklibs:skfirework/fx/spread",
args: {
config: {
n: 30,
v: 0.5,
g: 0.04,
tick_cmdv: [{cmd:"particle flame ~ ~ ~ 0 0 0 0 1 force"}],
cmdv: [
{
cmd: "function sklibs:skfirework/fx/firework",
args: {
config: {
shape: 0,
colors: [
{from: [I;13047173],to: [I;16761035]},
{from: [I;16711680],to: [I;10824234]}
],
n: 1
}
}
}]
}
}
}]
}
}示例：给烟花增加TNT爆炸效果和音效
mcfunction
function sklibs:skfirework/fx/launch {
config:{
life: 50,
cmdv: [
{cmd: "playsound minecraft:entity.firework_rocket.large_blast ambient @a ~ ~ ~ 1000"},
{cmd: "summon tnt ~ ~ ~"},
{cmd: "summon tnt ~ ~ ~"},
{cmd: "summon tnt ~ ~ ~"},
{cmd: "summon tnt ~ ~ ~"},
{cmd: "function sklibs:skfirework/fx/spread",
args: {config: {
n: 30,
v: .5,
g: 0.04,
tick_cmdv: [{cmd:"particle flame ~ ~ ~ 0 0 0 0 1 force"}],
cmdv: [
{cmd: "summon tnt ~ ~ ~"},
{cmd: "function sklibs:skfirework/fx/firework",
args: {config:{
shape: 0,
colors: [{from:[I;13047173],to:[I;16761035]},{from:[I;16711680],to:[I;10824234]}],
n: 1
}}}]
}}}]
}
}示例：可以二次扩散的烟花
mcfunction
function sklibs:skfirework/fx/launch {
config: {
life: 30,
cmdv: [
{cmd: "playsound minecraft:entity.firework_rocket.large_blast ambient @a ~ ~ ~ 1000"},
{cmd: "function sklibs:skfirework/fx/spread",
args: {config: {
t: [40,70],
n: 6,
v: 1,
g: 0.02,
tick_cmdv: [{cmd:"particle dragon_breath ~ ~ ~ 0 0 0 0 1 force"}],
cmdv: [
{cmd: "playsound minecraft:entity.firework_rocket.large_blast ambient @a ~ ~ ~ 1000"},
{cmd: "summon tnt ~ ~ ~"},
{cmd: "function sklibs:skfirework/fx/spread",
args: {config: {
n: 30,
v: 0.5,
g: 0.01,
tick_cmdv: [{cmd:"particle flame ~ ~ ~ 0 0 0 0 1 force"}],
cmdv: [
{cmd: "function sklibs:skfirework/fx/firework",
args: {config: {
shape: 0,
twinkle: 1,
colors: [{from:[I;13047173],to:[I;16761035]},{from:[I;16766720],to:[I;16777184]}],
n: 1
