Well, this isn't a request section, but I'll go ahead and do this since it is quite simple to do.
Change the SpellIds to what you want. Well, change whatever to what you want.
In each event, you will see SelectTarget(SELECT_TARGET_RANDOM, 0, 100.0f, false). If you don't want your creature to target a random player when casting a spell, then change it to other types. 100.0f is the range, you can change it to anything above 5.0f.
