Description
SubTick
This mod uses Fallen's fabric mod template.
A carpet extension that allows you to freeze and step to any specific tick phase, as well as step through tile ticks, fluid ticks, block events, entities, and block entities individually. Get it on your client for highlights and a HUD.
Commands
[] represents an optional argument, and <> represents an obligatory argument. If an argument is written like count=1, that means 1 is the default value.
- tick freeze [phase=subtickDefaultPhase]: Freezes/unfreezes right before phase.
- tick step [count=1] [phase=subtickDefaultPhase]: Steps count ticks, ending right before phase. Supports tick step 0 [phase] to step to a later phase in the same tick.
- phaseStep [count=1]: Steps count phases forward, stepping to the next tick if necessary.
- phaseStep <phase>: Steps to phase, within the current tick.
- phaseStep <phase> force: Steps to the next phase stepping to the next tick if necessary.
- queueStep <queue> [count=1] [range=subtickDefaultRange]: Steps through count elements in queue withinrange blocks, within the current tick. Set range to -1 for unlimited range.
- queueStep <queue> [count=1] [range=subtickDefaultRange] force: Steps through count elements in queue within range blocks, stepping to the next tick if necessary. Set range to -1 for unlimited range.
Special cases
Block events and block ticks have the option to use a different mode for stepping. Block events can step through whole block event depths, and block ticks can step through whole block tick priorities.
- queueStep blockEvent [mode=index] [count=1] [range=subtickDefaultRange] [force]
- queueStep blockTick [mode=index] [count=1] [range=subtickDefaultRange] [force]
