The if/else block is the fifth block in the orange Control section.
It is used in combination with a Logic block, that you can put inside the if/else block. The Logic block determines if the blocks in the if/then section of the block will be run or the blocks in the else section will be run!
Logic blocks can primarily be found in the Sensors and Operators sections.
Logic blocks can either be True or False. If the block is True, the first set of blocks will run; if it's False, the second set of blocks will run. For example, if we use the force sensor logic block as shown in the picture above, it will be False if the sensor isn't pressed and True if the sensor is pressed. So, if the force sensor is pressed, then the blocks inside the if/then section will run; else, the blocks in the else section will run!
