Math Expressions

The Evaluate Math Expression and If Math Expression events allow mathematical expressions to be used for performing calculations.

If Math Expression

Expression

e.g. $health >= 0...

True

Add Event

Expressions allow you to use many mathematical operations such as:

• + add
• - subtract
• * multiply
• / divide
• == equal to
• != not equal to
• >= greater than or equal to

You are also able to use the following functions

• min(a, b) return the minimum of two values a and b
• max(a, b) return the maximum of two values a and b
• abs(a) return the absolute value of a

You can use variables in expressions by typing $ and searching for the variable's name.

If you want to combine multiple expressions, you can use the following:

• || or
  (e.g., $Local0 == 0 || $Local1 == 0: if either variable Local0 equals 0 or variable Local1 equals 0)
• && and
  (e.g., $Local0 == 0 && $Local1 == 0: if both variable Local0 equals 0 and variable Local1 equals 0)
