Modifier Data structure:
Field Name | Field Type | Notes |
---|---|---|
UUID | UUID | |
Amount | Double | May be positive or negative. |
Operation | Byte | See below. |
The operation controls how the base value of the modifier is changed.
- 0: Add/subtract amount
- 1: Add/subtract amount percent of the current value
- 2: Multiply by amount percent
All of the 0's are applied first, and then the 1's, and then the 2's.
Entity Effect
Packet ID | State | Bound To | Field Name | Field Type | Notes |
---|---|---|---|---|---|
0x72 | Play | Client | Entity ID | VarInt | |
Effect ID | VarInt | See this table. | |||
Amplifier | Byte | Notchian client displays effect level as Amplifier + 1. | |||
Duration | VarInt | Duration in ticks. (-1 for infinite) | |||
Flags | Byte | Bit field, see below. | |||
Has Factor Data | Boolean | Used in DARKNESS effect | |||
Factor Codec | NBT Tag | See below |
The following information needs to be added to this page: | |
What exact effect does the blend bit flag have on the client? What happens if it is used on effects besides DARKNESS? |
Within flags:
- 0x01: Is ambient - was the effect spawned from a beacon? All beacon-generated effects are ambient. Ambient effects use a different icon in the HUD (blue border rather than gray). If all effects on an entity are ambient, the "Is potion effect ambient" living metadata field should be set to true. Usually should not be enabled.
- 0x02: Show particles - should all particles from this effect be hidden? Effects with particles hidden are not included in the calculation of the effect color, and are not rendered on the HUD (but are still rendered within the inventory). Usually should be enabled.
- 0x04: Show icon - should the icon be displayed on the client? Usually should be enabled.
- 0x08: Blend - should the effect's hard-coded blending be applied? Currently only used in the DARKNESS effect to apply extra void fog and adjust the gamma value for lighting.
