Have I miss understood something or is the document outdated info about how accuracy, evasion and hit chance is calculated?
This is what DefaultGameplayRule script says: (line 101 ->)
float hitChance = 2f;
if (attackerAcc != 0 && dmgReceiverEva != 0)
hitChance *= (attackerAcc / (attackerAcc + dmgReceiverEva));
if (attackerLvl != 0 && dmgReceiverLvl != 0)
hitChance *= ((float)attackerLvl / (float)(attackerLvl + dmgReceiverLvl));
Document says:
Hit chance = 2 * (10 / (10 + 30)) = 0.5
Default game play rules is modifying hit change with acc vs eva and level difference, so the documentation should say something like:
Hit chance = 2 *(attackerAcc / (attackerAcc + dmgReceiverEva)) *(attackerLvl / (attackerLvl + dmgReceiverLvl))
Example:
attackerAcc = 10
dmgReceiverEva = 30
attackerLvl = 10
dmgReceiverLvl = 10
Hit chance: 2 * (10 / (10 + 30) * (10 / (10 + 10) = 0.25
Then second character will receives damage if random result from 0 to 1 <= 0.25
