Control Block
Description
The Loop block iterates over a list of blocks a fixed number of times. The number of times can be a provided constant or a numerical expression. The loop block includes a Yield at the end making the maximum loop rate the controller sample rate.
Escapes
The Loop block does not produce any escapes.
Examples
Clicking on the numeric field provides a keypad to enter the number of iterations. Note that this is an integer keypad since the value has to be a whole number:
This block list performs 5 individual moves with a 1/2 second delay between each one:
This block list writes ascending values into a list.
This block list makes the number of parts indicated in an editor:
However checking with the editor control every loop takes a small amount of time. If this was a time critical loop it would be better to copy the editor value into a variable and then work directly with the variable as the loop count:
