if(condition) branch_true else branch_false
• | condition | – | If this executes as true then branch_true is executed otherwise branch_false is executed. | |
• | branch_true | – | Can be either a single statement, a block statement, or a null statement. | |
• | branch_false | – | Can be either a single statement, a block statement, or a null statement. |
Any of the statements can be null statements.
Specification
Type | Condition |
---|---|
integer | True if it is not zero. |
float | True if it is not zero.[1] |
string | True if its length is not zero. |
key | True only if it is a valid key and not NULL_KEY. |
vector | True if the vector is not ZERO_VECTOR. |
rotation | True if the rotation is not ZERO_ROTATION. |
list | True if the length is not zero. Note that correct behavior is only seen with Mono-compiled scripts; LSO-compiled scripts incorrectly resolve to false if the list is non-empty: BUG-230728 |
