Hey,
I’m new to unity and I have this script for one of my enemies. The only problem is that I’ve been trying to make them shoot upwards when I jump in the air. They only seem to shoot straight and not on the Y axis. I’ve been looking for a solution on the internet for a couple of days now, but without any luck so I decided to try here.
Thank you for your time!
