After reviewing code and what i wrote i thought id redo and clean up a bit and try to explain more.
Heres WHY i did the changes to original code.
1. Original code used factors such as str/dex/agi which is incorrect.
the only thing that effects chance to hit are levels and weapon
skills.
2. Orginal caps on to hit were way to high/low in relation to live
3. Was not weighting weapon skill enough in chance to hit imho.
Basically in eqlive the following is true regarding to-hit values..
1. Level is the single biggest factor in to-hit rolls.
2. Offense skill and Weapon skill are the only other factors figured.
3. Attack buffs do NOT change it, stats do NOT change it
If the code below is terrible please let me know and perhaps i can give the forms outta here to someone that can code better.
2 known problems are
1. Weapon skill is checked off PRIMARY hand for BOTH weapons.
i THINK this is a bug someplace before my code when it calls
calls for weapon skill.
2. I am using educated guessing on the 35 min cap.
I based my work off some of the following links...
http://www.thesteelwarrior.org/forum...;threadid=3803
http://www.eqbeastlord.com/forums/viewtopic.php?t=10317
And more pages like that in general...
Anyhow here is the code... Line 156 is starting number in attack.cpp
Code:

Any feedback is appreciated on this please
new to-hit code to test if you wish...
Linear Mode
