Loop node provides the ability to repeat execution on dedicated nodes group multiple times.
Let’s imagine a scenario where you need to jump to 6 different asteroid belts and make a bookmark on each one. In general, you should create many equals nodes in long construction like this.
// SCREEN six times repeated nodes with the same behavior
But with the Loop node, you can reuse multiple times the short nodes construction. There is how you can solve the task using the Loop node.
// SCREEN Loop node 6 times jumps to asteroid belt by index and make a bookmark on each one.
Loop nodes could be used together with Continue(LINK) and Break(LINK) nodes.
