Randomized permutations

[tulip dragon]

All my blocks with randomized permutations are broken. How would I recreate this in scripts? Haven't really messed with blocks in scripts before.

// random numbers [0,1,2,3]
const randomNumber = Math.floor(Math.random()*4);

// random boolean [false, true]
const randomBoolean = Math.random() < 0.5 ? true : false;

// random strings
const values = ["a", "b", "c"]
const randomString = values[Math.floor(Math.random()*values.length)];

// Then change the permutation of the block with the value obtained
const state = block.permutation.withState("example:state", randomNumber);
block.setPermutation(state);

You can use this in your custom component

How would I set up the custom component?

[slate turret]

import { world } from '@minecraft/server';

// Register your component with an identifier
world.beforeEvents.worldInitialize.subscribe(initEvent => {
    initEvent.blockComponentRegistry.registerCustomComponent('example:identifier', {
        
        // Choose which event you will use
        onPlace: e => {
            
            // Get the block
            const { block } = e;
            
            // Get a random value between 0 and 3
            const randomNumber = Math.floor(Math.random()*4);
            
            // Set the block state based on this value
            const state = block.permutation.withState("example:state", randomNumber);
            block.setPermutation(state);
        }
    });
});

Then add the custom component to your block's json file using the identifier you chose.

"minecraft:custom_components": [
  "example:identifier"
]

Sorry for late response but it isnt working

[slate turret]

Can you send the code?

[tulip dragon]

Script or block?

[slate turret]

script

[tulip dragon]

// Register your component with an identifier
world.beforeEvents.worldInitialize.subscribe(initEvent => {
  initEvent.blockComponentRegistry.registerCustomComponent('myth:beer_random', {

    // Choose which event you will use
    onPlace: e => {

      // Get the block
      const { block } = e;

      // Get a random value between 0 and 3
      const randomNumber = Math.floor(Math.random() * 2);

      // Set the block state based on this value
      const state = block.permutation.withState("myth:beer_variant", randomNumber);
      block.setPermutation(state);
    }
  });
});```

Can you send the block too?

The code seems correct, if there was an error setting the permutation it may be that it does not exist in the block or the value is not accepted.

[slate turret]

You have not set the block state

And in your script you used Math.floor(Math.random()*2), this gives you a random number between 0 and 2 but without including 2, use Math.floor(Math.random()*3) instead

What does this mean?

[slate turret]

Sorry the file had an error, try this one

[tulip dragon]

It works, thanks!

@slate turret how this works can I use it on custom logs

[slate turret]

maybe, this is for random states
