NEED HELP WITH MY TERRARIA MOD

[TastyVibe]

so for pointers this was my first attempt at ai and it well went badly as i have came here... below is the script and on the line

" Projectile projectile = Projectile.NewProjectileDirect(NPC.Center, projectileVelocity, ProjectileID.Fireball, 20, 50, Main.myPlayer);"

im getting 2 errors one being argument 1 cannon convert from mirosoft.Xna.FrameWork.Vector2 and argument 3 not working bc it cannot convert from 'short' to microsoft.XnaFrameWork.Vector2
so with that said if anyone can help me fix this issue it would mean alot as im quite lost being in the modding community for around 3 days now.

using Terraria.ModLoader;

}

}

You're probably following old tutorials cause your NewProjectile lines are missing a source parameter. Take a look at the TML wiki and Examplemod. Entity Source

Not following old tutorials just getting back into it after a while so im kinda outdated to things so thanks for the push into the right direction.
