if( condition ) branch
| • | condition | – | If this executes as true then branch is executed. | |
| • | branch | – | Can be either a single statement, a block statement, or a null statement. |
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 |
