for( initializer; condition; increment ) loop
• | initializer | – | Executed once just before checking condition. | |
• | condition | – | If this executes as true then loop is executed. | |
• | increment | – | Executed after loop, then condition is checked again. | |
• | loop | – | 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 |
Examples
Notes
A for loop is the same as a while loop as below.
initializer; while(condition); { loop; increment; }
