&& !get_val(XB1_LT)in to the if statement we are telling the Cronus Zen to only run the combo if the Right Trigger has a value and the Left Trigger does not.
&&means 'and' in GPC and
!means not. So the if statement now reads 'if Right Trigger has a value and Left Trigger does not'. Which means when using this code in game the Cronus Zen will only Rapid Fire your gun when you are not aiming down the sights. You can use the build and run function to see this code in action.
