Custom Projectiles that circle you

Without coding them manually, I think not.

You could use a bit of highschool math for this. You don´t event need to code, although i did (I created a homing projectile recentely). Pythagoras theorem or however it is called in english can help you. You need two triangles: One for your rotationYaw and one for your rotationPitch. After that lot of work with "sin", "cos" and "tan". Keep an eye on the 4 Quadrants however. If you want to edit the arrowentity you have to go into the code and add the arrowentity as a dependency and convert it to a normal entity for easy usage. Respond to me, if you want more insight into how to do it, if that is even what you want.
