I was tired of mission and activities mods on where enemies had an excelent accuracy, they can shoot and hit you if they're not even directly aiming at you, shooting throw obstacles and making impossible shots... Like enemies in vanilla game, like when O'Neal "soldiers" can shoot Trevor's feet when he's covered behind his Bodhi pickup at 300m, with the shitty 9mm pistols...
That's why i created Accuracy Fix, a GTA V mod that forces all the peds on the game to have the same accuracy. The script is constantly checking for all the peds who are human, not player and haven't got the desired accuracy level, so it changes their accuracy.
I personally like when the enemies can't hit me so easily, but when they do it, they kill me or my character gets badly injured... So this script is recommended for people who likes that kind of realism and playing style. Anyway, you can also use it to increase the accuracy, if you want to.
