Eval Extra

Description

This is an addon to apply math expressions in some settings of the menu
With this, you can write advanced math in menu. Especially, this addon is useful to write advanced conditions in Condition Requirement

Example

stone:
  id: stone
  amount: "25 + 3"

stone:
  id: stone
  amount: "FLOOR(SQRT(18))" # The amount will be the floor value of the square root of 18, which is 4

test-view-requirement:
  type: predicate
  slot: 1
  button:
    id: exp_bottle
    name: "&cA exp bottle"
    lore:
      - "You will see this icon when the level is higher than 5"
  view-requirement:
    level:
      condition: "{level} > 5" # This will check if the player's level is higher than 5

Operator

The basic is the use of math operators in the expressions (+, -, *, /, etc)
Examples:

amount: "5 + 7" # The amount will be 11

amount: "{level} % 64 + 1" # The amount will be from 1 to 64, based on the level

Along with math operators, you can also use Boolean operators (>, <, =, >=, <=, etc) to compare values.
Example:

condition: "{level} > 5" # This will check if the player's level is higher than 5

Supported Operators

Function

Functions are the process of “input to output”, take the input and returns the corresponding output.
Functions
Example:

amount: "FLOOR(SQRT(18))" # The amount will be the floor value of the square root of 18, which is 4

String Functions

This addon also accepts comparing strings with String Functions
It includes:
- STRCT("this", "is") check if is is in this (this contains is)
- STREDW("String", "ing") check if String ends with ing
- STREQ("str1", "str1") check if str1 equals str1
- STREQIC("str1", "str1") check if str1 equals str1 (case-insensitive)
- STRLEN("Hello World") get the length of Hello World
- STRMP("String", "String-?") check if String matches the RegExr pattern String-?
- STRSTW("String", "Str") check if String starts with Str

Skip the Evaluation

If you want to skip your string from evaluation for some reason, put [skip-eval] before your string
- Example: If you want to skip 1 + 1, put [skip-eval] like this [skip-eval] 1 + 1

Variable

You can evaluate an expression as a variable by using the variable {eval_<expression>}

For example:

{eval_1 + 2}
{eval_{level} * 100}
{eval_FLOOR(SQRT(18))}
