Goop
Goop is a Mod that adds advanced Slime and Splatter Visual Effects.
Built-in Effects
Since emitters work using Resourcepacks as if v0.4, there's 3 Optional Resourcepacks included in the mod.
- Slimier Slimes (Enabled by Default)
- Slimes and Magma Cubes leave behind puddles when they hit the ground and splatter when taking damage
- Sensible Blood (Enabled by Default)
- Adds Damage Emitters to all Mobs where it makes sense that they could bleed
- Some Mobs bleed different colors
- Only Red Blood is marked as mature; all other effects are unaffected by the censor client config
- EVERYTHING BLEEDS (Disabled by Default)
- Adds Red Blood Damage Emitters to all Living Entities
