if-else( condition; branch_true; 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 |

- ^ The OpenSim LSL compiler will not do this implicitly. You will need to use an explicit check.
