How to make this function in voxel.js engine generate a labyrinth

Questions

I want with this function:

game=createGame({
texturePath:‘textures/’,
generate: function(x,y,z) {
const rx = Math.floor(Math.abs(x)) % 10;
const ry = Math.floor(Math.abs(y)) % 10;
const rz = Math.floor(Math.abs(z)) % 10;

// Si cualquiera de tus condiciones se cumple, devuelve 1 (brick)
if ((rx < 5 && ry < 5 && rz < 5) || 
    (rx >= 5 && ry < 5 && rz < 5) || 
    (rx < 5 && ry >= 5 && rz < 5) || 
    (rx < 5 && ry < 5 && rz >= 5)) {
    return 1; // Material 'brick' (índice 0 en tu array de materials)
}

return 0; // Vacío

},
chunkDistance: 1,
distance: 2,
materials: [‘brick’]
})

Generate this, but with less lag:

Its possible? Thanks anyway!!!

This is the code:

game=createGame({
texturePath:'textures/',
generate: function(x,y,z) {
const rx = Math.floor(Math.abs(x)) % 10;
const ry = Math.floor(Math.abs(y)) % 10;
const rz = Math.floor(Math.abs(z)) % 10;

// Si cualquiera de tus condiciones se cumple, devuelve 1 (brick)
if ((rx < 5 && ry < 5 && rz < 5) || 
    (rx >= 5 && ry < 5 && rz < 5) || 
    (rx < 5 && ry >= 5 && rz < 5) || 
    (rx < 5 && ry < 5 && rz >= 5)) {
    return 1; // Material 'brick' (índice 0 en tu array de materials)
}

return 0; // Vacío

},
chunkDistance: 1,
distance: 2,
materials: ['brick']
})
