I was testing out all of my spells in the map I'm working on at the moment and noticed that custom projectile spells didn't always shoot so precise. I looked through the codes and noticed that it was because I moved the dummy projectile towards he's facing angle instead of the angle between the points even though I set the dummy units facing to that angle. (The point of the caster and target point of ability being cast.)
Trying to fix this I used the angle between the points instead, but no matter what I did it turned out to be something complete else. The projectiles moved in all sorts of strange directions... I tried using what I usually do, taking the angle*bj_DEGTORAD/bj_RADTODEG. But none of them worked... Here is the code for one of the projectile spells:
Any help is appreciated.
