Private constructorReadonly afterReturns a collection of after-events for system-level operations.
Readonly currentRepresents the current world tick of the server.
Readonly serverContains the device information for the server.
Cancels the execution of a function run that was previously scheduled via run.
This function can be called in early-execution mode.
Function callback to run at the next game tick.
An opaque identifier that can be used with the clearRun
function to cancel the execution of this run.
Runs a specified function at the next available future time. This is frequently used to implement delayed behaviors and game loops. When run within the context of an event handler, this will generally run the code at the end of the same tick where the event occurred. When run in other code (a system.run callout), this will run the function in the next tick. Note, however, that depending on load on the system, running in the same or next tick is not guaranteed.
This function can be called in early-execution mode.
trapTick.ts
import { world, system } from "@minecraft/server";
function trapTick() {
try {
// Minecraft runs at 20 ticks per second.
if (system.currentTick % 1200 === 0) {
world.sendMessage("Another minute passes...");
}
} catch (e) {
console.warn("Error: " + e);
}
system.run(trapTick);
}
Functional code that will run when this interval occurs.
Optional tickInterval: numberAn interval of every N ticks that the callback will be called upon.
An opaque handle that can be used with the clearRun method to stop the run of this function on an interval.
Runs a set of code on an interval.
This function can be called in early-execution mode.
every30Seconds.ts
import { world, system, DimensionLocation } from "@minecraft/server";
function every30Seconds(targetLocation: DimensionLocation) {
const intervalRunIdentifier = Math.floor(Math.random() * 10000);
system.runInterval(() => {
world.sendMessage("This is an interval run " + intervalRunIdentifier + " sending a message every 30 seconds.");
}, 600);
}
The instance of the generator to run.
An opaque handle that can be used with clearJob to stop the run of this generator.
Queues a generator to run until completion. The generator will be given a time slice each tick, and will be run until it yields or completes.
This function can be called in early-execution mode.
cubeGenerator.ts
import { system, BlockPermutation, DimensionLocation } from "@minecraft/server";
function cubeGenerator(targetLocation: DimensionLocation) {
const blockPerm = BlockPermutation.resolve("minecraft:cobblestone");
system.runJob(blockPlacingGenerator(blockPerm, targetLocation, 15));
}
function* blockPlacingGenerator(blockPerm: BlockPermutation, startingLocation: DimensionLocation, size: number) {
for (let x = startingLocation.x; x < startingLocation.x + size; x++) {
for (let y = startingLocation.y; y < startingLocation.y + size; y++) {
for (let z = startingLocation.z; z < startingLocation.z + size; z++) {
const block = startingLocation.dimension.getBlock({ x: x, y: y, z: z });
if (block) {
block.setPermutation(blockPerm);
}
yield;
}
}
}
}
Functional code that will run when this timeout occurs.
Optional tickDelay: numberAmount of time, in ticks, before the interval will be called.
An opaque handle that can be used with the clearRun method to stop the run of this function on an interval.
Runs a set of code at a future time specified by tickDelay.
This function can be called in early-execution mode.
A class that provides system-level events and functions.
