Syntax

$and[condition1;(condition2);(...)]

$and accepts 1 to 100 arguments. Each argument must resolve to true, false, or a comparison using ==, !=, >=, <=, > or < (e.g. $getUserVar[coins]>=50). Any other value is an error (Invalid condition: <value>.). In a comparison, if both sides are numbers the comparison is numeric, otherwise it is a text comparison (code-unit order, so uppercase letters sort before lowercase ones). Both sides and the whole condition are trimmed.

Evaluation

Each condition argument is resolved at runtime. Conditions are evaluated from left to right and $and short-circuits: as soon as one condition is false, it returns "false" and the remaining arguments are not evaluated (so their side effects, and any error they would raise, do not happen).

Truth Table

Condition 1	Condition 2	Result
"true"	"true"	"true"
"true"	"false"	"false"
"false"	"true"	"false"
"false"	"false"	"false"

The same logic extends to 3 or more arguments — all must be "true" for a "true" result.

Using Conditions

$and works with any expression that evaluates to "true" or "false":

• Direct function results: $and[$checkCondition[...];$checkContains[...]]
• Inline comparisons: $and[$getUserVar[a]>0;$getUserVar[b]>0]
• Nested logical operators: $and[$or[...];$or[...]]

Inside $if, both $if[$and[cond1;cond2]] and $if[$and[cond1;cond2]==true] work, because $and returns the text true or false, which $if accepts as a condition.

Use Cases

• Multi-requirement checks: Verify that all prerequiredites are met before allowing an action.
• Form validation: Check that multiple fields are non-empty or valid.
• Access control: Combine role checks with resource availability checks.
• State verification: Confirm that multiple flags or state variables are all set correctly.

Common Pitfalls

• Order matters: conditions are evaluated left to right and evaluation stops at the first false one, so put cheap or guarding checks first.
• Non-boolean results: If a condition is neither true, false nor a comparison (e.g., a lone number or an empty string, as in $and[1] or $and[]), the engine raises an Invalid condition error.
• No argument: $and requires at least 1 argument (and at most 100); a bare $and is refused.

Examples

Checking Multiple Conditions

$if[$and[$message!=;$getUserVar[coins]>=50]==true]
  $title[Transaction Approved]
  $description[Both conditions met! Deducting 50 coins for: **$message**]
  $color[#57F287]
$else
  $title[Transaction Denied]
  $description[You must provide an item name and have at least 50 coins.]
  $color[#ED4245]
$endif
