All these options, offered by MANU, open up more opportunities for the user compared to the usage of only one trigger to start and stop the animation. Creating trigger chains, remember that the calculations in the chain occur sequentially, from left to right. The calculation algorithm checks each trigger and operator in order. If one of the triggers changes its state, even for a fraction of a second, the mechanism for checking the trigger chain will start again. The chain checking does not always occur, but it is triggered every time an event occurs. The new event causes the trigger state to change from TRUE to FALSE. The combination of trigger states (TRUE and FALSE) defines the logic of the trigger chain. If, after all calculations, the trigger chain output is TRUE, then the animation starts. If the output is FALSE, then the animation does not play. When, during the animation playback, a new event occurs, it activates the checking of the trigger logic chain. The animation playing will stop if the output of the checking is FALSE. If the output of checking is TRUE, then the running animation continues to play. The animation does not start again, it just keeps playing, ignoring the TRUE value.
