Conditional branching
Lua uses the if, else, elseif, then, and end keywords to do conditional branching.
Note that in Lua, nil and false are false and everything else is true. Zero (0) is true in Lua.
The syntax of a conditional block is as follows:
if expression then
block
elseif expression then
block
else
block
end
Where:
• expression is Lua code that evaluates to either true or false
• block consists of one or more Lua statements
Example: If
if 0 then
print("Zero is true!")
else
print("Zero is false.")
end
Output:
Zero is true!
Example: Comparison
x = 1
y = 2
if x and y then
print("Both x and y are true")
end
Output:
Both x and y are true
Example: If and else
x = 2
if not x then
print("This is from the if block")
else
print("This is from the else block")
end
Output:
This is from the else block
