Hello!  I am trying to create an item that shoots a fireball in the direction of the player's view.  Currently, it does shoot the fireball but the fireball is curving a bit depending on where the player is looking (also, when looking down, even slightly, it shoots the fireball directly below the player).  I am struggling to figure out the problem.  I have already looked at other Minecraft classes, such as the Ghast and Bow classes.  Any help would be appreciated, thanks!

try to use 1.0F as last parameter in shootFromRotation

The last parameter in the shootFromRotation method is for the inaccuracy.  In my case, it has nothing to do with the issue of the fireballs practically looping in circles whenever I use the wand item.

then you can test a bit with the speed

@jaxbymc42did you find a solution? I ran into the same problem...

why you need ved3 variable if u dont use it?
