Ask for a Lua syntax

[sdgmlj]

There are two layers of braces in a table. How can I get its value?
For example:

a = {
{
b = 5
},
}

a.b = 5 ?? That's wrong,How can I express it?

[Xorimuth]

a[1]["b"] or a[1].b both work.

[sdgmlj]

a[1]["b"] or a[1].b both work.

Thank you, but it still reported an error
attempt to index field'?'(a nil value)

The content of the original script is as follows:

action = {
{
type = "direct",
action_delivery = {
{
type = "projectile",
projectile = "anti-material-rifle-ammo-3",
starting_speed = 3,
direction_deviation = 0.02,
range_deviation = 0.02,
max_range = 50,
source_effects = {
{
type = "create-explosion",
entity_name = "explosion-gunshot",
},
},
},
},
force = "not-same",
},
},

I want to get the value of "max_range". How can I express it?

[Pi-C]

action = {
{
type = "direct",
action_delivery = {
{
type = "projectile",
projectile = "anti-material-rifle-ammo-3",
starting_speed = 3,
direction_deviation = 0.02,
range_deviation = 0.02,
max_range = 50,
source_effects = {
{
type = "create-explosion",
entity_name = "explosion-gunshot",
},
},
},
},
force = "not-same",
},
},

Please, use code markup! This way, it's much easier to read because indention will not be removed:

Code: Select all

action = {
  {
    type = "direct",
    action_delivery = {
      {
	type = "projectile",
	projectile = "anti-material-rifle-ammo-3",
	starting_speed = 3,
	direction_deviation = 0.02,
	range_deviation = 0.02,
	max_range = 50,
	source_effects = {
	  {
	    type = "create-explosion",
	    entity_name = "explosion-gunshot",
	  },
	},
      },
    },
    force = "not-same",
  },
},

I want to get the value of "max_range". How can I express it?

That would be

Code: Select all

action[1].action_delivery[1].max_range

action = {
{
type = "direct",
action_delivery = {
{
type = "projectile",
projectile = "anti-material-rifle-ammo-3",
starting_speed = 3,

entity_name = "explosion-gunshot",

Thank you. I see. The back one is also two floors.
