Forノードは、Runへインパルスを入力したときに、LoopIteration出力から特定の回数だけインパルスを出力するために使用されるノードです。
使用方法
Count入力は、LoopIteration出力から何回インパルスが出力されるかを決定するものです。この値は、LoopStartインパルス連鎖が完了した直後、LoopIterationからインパルスが出力される前に評価されることに注意してください。
Reverse入力は、Iteration出力値をLoopIterationごとに増加させるか減少させるか制御します。デフォルトはFalseで、Iterationは動作するたびに増加します。
LoopStart出力は、Runへインパルスを入力した後、1回インパルスを出力します。インパルス連鎖は、LoopIterationからインパルスが出力される前に完了します。
The LoopIteration output fires impulses sequentially until the total number which have been fired is equal to the Count input. Each impulse chain started from LoopIteration completes before the following one is fired.
The LoopEnd output fires an impulse once the final impulse chain started from LoopIteration has ended.
The Iteration output value is either incremented or decremented each time a new impulse is fired from LoopIteration, depending on the value of Reverse. If Reverse is False, Iteration is incremented each time an impulse is fired from LoopIteration starting with the value 0, during the first iteration, and ending with Count - 1 on the final iteration. If Reverse is True, the Iteration value is Count - 1 on the first iteration and decremented each time down to 0 on the final iteration.
Note that all impulse chains started from this node effectively continue the one which arrived at Run, meaning that any temporary values from previous nodes are still available. All iterations from LoopIteration complete within a single frame update and therefore this can produce framerate hitches if an excessively demanding computation is performed. There is a failsafe which will put this node into an error state (node visual turns red) if a frame is delayed excessively - this helps prevent complete freezes.
