Modding Help Projectile Mirroring on Spells?

So I made a few spells which work pretty well so far, but:
Unlike other projectiles, Spell projectiles don't seem to be turning themselves around when being cast to the other side of the character.

Any way to change this?



This is quite important for some spells like fire-breathing type things.
Hope someone can help.

---Edit---
No, set "Flippable: True" doesn't seem to work, neither on the spells .weaponability nor the .projectile file.

 

I had somewhat similiar issue recently and today accidentally solved it. Maybe my experience might help.

My ability was spawning a projectile through world.spawnProjectile command, which has the direction vector, by default it was {0, 0}

Code:

world.spawnProjectile(self.projectileType, vec2.add(position, self.projectileOffset), activeItem.ownerEntityId(), {0, 0}, false, params)

I've spent quite an hour trying to make it rotate, using something like "{math.cos(self.weapon.aimAngle), math.sin(self.weapon.aimAngle)}". It was rotating, but didn't flip, just like yours. So after a dozen of different methods this worked like a charm

Code:

 {mcontroller.facingDirection(), math.sin(self.weapon.aimAngle)} 

If you do not need rotation, then i guess {mcontroller.facingDirection(), 0} would do.
