If–Else

The If-Else category comprises control blocks which direct the flow of a program depending on the results of the tests carried out by these blocks. See Fig. 57.

If-Do

The if input socket takes a value block or compound block that represents a True or False value.

If the value block in the conditional input is True, it runs the blocks nested inside.

If the block in the conditional input is False, it skips the nested blocks.

If-Do-Else-Do

This block is an extension of the If-Else-Do block. It adds the else bracket into which the action blocks that are to be run if the tested input is False.

If-Do-Else If-Do-Else-Do

This block is a further extension of the If-Do-Else-Do block. A second conditional else if input is inserted and a bracket for actions to be run if the else if input is True.

If-Do Configuration

The If-Do block is configurable.

By clicking the gear icon on the block, extra elections can be added by dragging the else if or else blocks into the white area to connect under the if block in the configuration box:

• else if sections can add more conditional sockets to check for further input Boolean values, and a do bracket to contain action blocks to be run if the input is True. Multiple else if sections can be configured.

• a single else section can be added to the end to contain the action blocks to be run if none of the previous conditions are True.

To remove any of the else if or else sections, drag them back into the grey area of the configuration box.

To close the configuration box, simply click the gear icon once more.
