World.say is no working for me (i'm begginer on this)

[stark compass]

import {system, world } from '@minecraft/server';
let decir = void system.runInterval((world.say('say Hello starter!')), 20);

I don't know what i'm doing wrong, the compiler sends

"Property 'say' doesn't exist on type 'world'

[iron hill]

world.say world.sendMessage

[stark compass]

It compiled, i'll test.

One questions, what's the meaning of "() => {}" structure?

[iron hill]

its known as arrow function

function() {

}

() => {

}```

Minecraft says:

[Scripting][error]-Plugin [Invisible Armors - 0.0.1] - [main.js] ran with error: [TypeError: not a function    at <anonymous> (main.js:5)
]

[iron hill]

whats u game version

[stark compass]

1.19.63.01

[iron hill]

well you are using preview version api on stable version

you need preview version

or use old version types

[stark compass]

Where can i find the old types?

[iron hill]

what u used now?

[stark compass]

For what thing?

[iron hill]

to install types

[stark compass]

The command prompt. (?)

[iron hill]

which command i mean

[stark compass]

Tsc

I send tsc and that compiles the .ts

[iron hill]

i mean the npm command

[stark compass]

I don't used any npm command, except for installing Typescript

[iron hill]

im asking for that only

what command u used to install types

[stark compass]

Oh 😅

npm install -g typescript

[iron hill]

npm i @minecraft/server

is for stable

[stark compass]

And the "world.sendMessage" things are the same?

[iron hill]

use .say for stable

rest is same

[stark compass]

Now it says that "RunInterval" does not exist on "system"

Tick Awaition

since 1.19.50, we recieved two new methods that can be used for delaying function execution

// next tick
 system.run(func); 

// like setInterval
system.runSchedule( func, tickDelay );

// like cancel run
system.clearRun( runId );

// like clearInterval
system.clearRunSchedule( intervalId );

Example
for running code every 20ticks (1sec)

const TICKS_IN_SEC = 20;

const runSchedule = system.runSchedule( () => {
    console.warn( "show this message every " + TICKS_IN_SEC + " ticks");
}, TICKS_IN_SEC );

system.clearRunSchedule( runSchedule ); //stop execution loop

[iron hill]

system.runSchedule
