Deltatime

Expand Datapack Capabilities in Minecraft

This mod introduces special commands that grant datapacks access to vanilla game features previously unavailable for modification.

Core Features

The /deltatime command provides powerful tools for managing game mechanics:

• tickdelta — shows the duration of the previous tick in microseconds
• tickstoadd — increments a counter that remains stable even during server lag
• setitemcooldown — sets cooldown time for items with animation similar to ender pearls
• setability — modifies player character abilities
• setproperty — configures various player parameters

Effective Use of tickstoadd

This function allows creating timers independent of server performance. Here's a practical implementation example:

execute store result score tickstoadd objective run deltatime tickstoadd
scoreboard players operation untilactionprevious objective = untilaction objective
scoreboard players operation untilaction objective -= tickstoadd objective
execute if score untilaction objective matches ..0 unless score untilactionp objective matches ..0 run function my:action

The system prevents action execution even during sudden server latency spikes.
