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 unless elseif has been used |
Example 1: if condition is true...
local a = true
if a then
print("a = true")
else
print("a = false")
end |
Example 2: if condition is true... (alternative)
local a = true
if a == true then
print("a = true")
else
print("a = false")
end |
Example 3: if condition is not true do else...
local a = false
if a then
print("a = true")
else
print("a = false")
end |
Example 4: if a is 1 is elseif a is 2 do...
local a = 1
if a == 1 then
print("a = 1")
elseif a == 2 then
print("a = 2")
end |
