Simple RPG
This modification introduces full-fledged RPG mechanics into Minecraft. Killing mobs grants special experience that is separate from the vanilla enchantment system. As you accumulate experience, your character becomes stronger: maximum health increases and attack damage grows. Almost all mod parameters can be customized to your preferences.
Experience System
Experience for killing mobs is calculated using the following algorithm:
- Base mob value is calculated from its maximum health (default 0.05 per half-heart) and attack strength (default 0.1 per half-heart)
- The resulting value is multiplied by a coefficient based on the mob's armor (default 0.1 per armor point)
- Final experience is additionally adjusted based on world difficulty (default: peaceful - 0.25, easy - 0.75, normal - 1.0, hard - 1.25, hardcore - 1.5)
Character Progression
The character starts with 20 health points. With each new level, health increases by 2 points plus an additional 0.0075 multiplier per level. Attack damage is calculated using a special formula where base damage is multiplied by the attack coefficient:
atk 0.1
where atk is calculated by the formula:
(1 + flat (level - 1)) (1 + (level - 1) rate)
Flat and rate parameters are configurable (default: flat = 1, rate = 0.005). The value is then multiplied by additional coefficients from settings (default: base damage 0.75, variation 0.5).
Interface and Commands
The mod includes a special interface that can be disabled in settings:

The experience bar is located at the top of the screen. Its position and size can be changed through configuration.
Special commands are available for viewing statistics:
/pilotsrpg_stats [player]
OR
/simplerpg_stats [player]
Alternative Experience Mode
A damage-based experience mode is also available. In this mode, experience is awarded not for kills, but for each hit on mobs, taking into account their characteristics:
(damage Damage Multiplier) (1 + (XP Per Health Mob Health 0.1)) (1 + (XP Per Attack Mob Attack 0.4)) (1 + (XP Per Armor Mob Armor 0.2)) * Difficulty Modifier
where Damage Multiplier defaults to 0.13333333333333333.
