How do I fire bullets in the other direction

Right now my character only fires bullets to the left, does anyone know how to make him fire both ways Any help is appreciated, thank you in advance!

change the angle of the bullet sprite.

.....

Give the left headed bullets a negative speed.. ie -100.

Or set their angle... its easier to just set their default in object properties bullet behavior to -100 then set speed like normal after creation and they should go the right way (which would be left...).
