The operators

Operators are used to perform mathematical calculations or data manipulations of all kinds.

Here are the main operators:

• +: Addition of two numbers
• -: Subtraction
• *: Multiplication
• /: Division
• \: Quotient of Euclidean division
• %: Rest of Euclidean division
• ==: Equality between two values
• `, =`: Comparisons of two numbers
• and: "And" of two booleans
• or: "Or" of two booleans
• =: Assignment of a variable
• +=, -=, *= etc. : Operator + assignment of a variable

For an expression with multiple operators, the operators are applied in left-to-right order, with natural precedence as * takes precedence over +.

Example with different operators:

It is also possible to use parentheses like: (5 + 7) * 2.

Assignment Operators

In addition to the = operator, there are many assignment operators like +=, -=, *= etc. which combine a calculation and an assignment.

An example with *=, which performs a multiplication and stores the result in the same variable:

More complicated healing condition

Our current healing condition makes us heal as soon as we have lost 1 life point. We can improve it by healing ourselves only if our life is

To display the value of a variable or an expression in combat actions, use the standard function debug(). Example: debug(getTotalLife() * 0.75).
