Lua operators are expressions used to perform calculations or to pass arguments between different value types.
Conditional Operators
| if |
Query if something does or does not meet a certain condition.
|
| else |
Do something else if the query condition was not met.
|
| elseif |
Used to add additional if queries, if the initial query condition was not met.
|
| end |
This is used to close various queries or functions; there must be the same amount of end as if; except in instances where elseif has been used.
|
| Example 1: if condition is true (method 1) |
|
local a = true
if a then
print("a = true")
end |
|
| Example 2: if condition is true (method 2) |
|
local a = true
if a == true then
print("a = true")
end |
|
| Example 3: if condition is false |
|
local a = false
if a == false then
print("a = false")
end |
|
| Example 4: if condition is not met, then do else |
|
local a = false
if a then
print("a = true")
else
print("a = false")
end |
|
| Example 5: if condition is not met, then do elseif |
|
local a = false
if a then
print("a = true")
elseif not a then
print("a = false")
end |
|
Logical Operators
| and |
Allows you to check multiple conditions in a single if query.
|
| or |
Allows you to add an alternative if query into a single if query.
|
| not |
Checks if condition equals false or negative.
|
| Example 3: if condition is not true |
|
local a = false
if not a then
print("a = false")
end |
|
