Actions

“Actions” are specific in-game events that Prism monitors, like block-break or item-drop. They are always two lower-case words with a hyphen.

“Action Families” are related actions. They’re related in that they share the suffix, like block-break and hanging-break. They’re both “break” events.

The following is a list of all actions Prism v4 can monitor.

Default indicates whether Prism monitors this action by default. Some are disabled for performance or spam reasons.
Reversible indicates whether the action can be reversed (see Modifications)

³ Blocks broken by pistons will still be tracked. block-shift only applies to blocks moved.

Natural Spam

Several events are disabled by default because they mostly log natural events that you won’t care about. These are especially spammy after fresh chunk gen as water starts flowing and blocks adjust to their environment.

block-fade - Snow melt, grass/nylium blocks fading into dirt/netherrack, etc.
block-form - Snow fall, obsidian formation, etc.
block-spread - Vine, amethyst, mushroom, and other growth. Grass, mycelium, and mushrooms, spreading.
fluid-flow - Tracks the flow of fluids. Strongly recommend a drain tool. Still tracks flow breaking blocks.

If you plan to enable any of these, we strongly recommend you use a filter or increase their purge rate.
