About Custom Boss
From Steam Workshophttps://img.shields.io/static/v1?label=KF2&message=Mutator&color=blue https://img.shields.io/static/v1?label=config&message=INI%20tunable&color=orange…
Based on: DKCustomBosses https://steamcommunity.com/sharedfiles/filedetails/?id=3692681287
* Fixed Healthbar * Fixed Wave End * Improved invisible proxy behavior * Compatible with RetryXwave
Changed package/mutator name to avoid conflicts with existing DKCustomBosses installs:
?Mutator=CustomBoss.CustomBossMut[/code]
Create this fine inside the Config folder:
[b]KFCustomBoss.ini[/b]
[code][CustomBoss.CustomBossMutConfig]
ConfigVersion=1
bEnabled=True
bLogEnabled=True
ReplacementChance=1.0
BossPool=(BossPath="FalitaZed.CustomBoss1",MinWave=11,MaxWave=11,Weight=1)
BossCaptions=(ClassName="CustomBoss1",Caption="Custom boss incoming.")
BossPool=(BossPath="FalitaZed.CustomBoss2",MinWave=11,MaxWave=11,Weight=1)
BossCaptions=(ClassName="CustomBoss2",Caption="Another custom boss incoming.")
📋 Config notes:
ReplacementChance=1.0 means the vanilla boss will always be replaced. Use 0.5 for a 50% replacement chance.
BossPool adds one custom boss option. BossPath must use Package.Class format. MinWave and MaxWave control which waves the boss can appear on. Weight controls random selection chance when multiple bosses are eligible.
Example: Weight=1 and Weight=1 = CustomBoss1= 50% CustomBoss2= 50% Weight=3 and Weight=1 = CustomBoss1= 75% CustomBoss2= 25%
BossCaptions is optional. ClassName must match the class name, not the full package path.
