Operators

Conditions

A condition is an expression that is evaluated to a value which is then interpreted as true or false. In Lua, any value that is not nil or false is true. Conditional blocks are then executed if the condition is true:

if 5+5 == 10 then
  print("yes, 5+5 is 10")
end

We can use certain operators in order to generate true or false values. These operators are in lua

operator	meaning	true expression
==	equal	5==5
~=	not equal	5~=6
<	less	5<6
>	greater	6>5
<=	less or equal	5<=5
>=	greater or equal	5>=5
or	true if one of the values is true	true or false
and	true if both values are true	true and 5
not	inverts a value	not false
