It should also be noted that almost all blocks have inputs that receive data of various types. Input connectors are located at the top of the block in the middle. Each block also has outputs that transmit data after the inner logic of the block is executed. Connectors are at the bottom, in the middle of the block.
In the Constructor, you can also move and delete groups of blocks. To do this, hold the "CTRL" button and select the desired area with the blocks and move them all together at once as you do with a single block (see Fig. 4). To delete a block, press "Backspace" or "Delete".
