End spike feature

The end_spike feature can be used to place end spikes (also known as obsidian pillars) in the world.

Configuration

The following configuration options are available:

Option Type Description
crystal_invulnerable (optional in Json, defaults to false) boolean Whether the crystals on top of the end spikes should be invulnerable.
spikes A list of Spikess. See below for more information The spikes to place. If the array is empty, the default end spikes are placed
crystal_beam_target (optional) A BlockPos (In Json, the BlockPos is represented via an array of coordinates. First element is the x coordinate and so on.) The target of the crystal beam.

In code, the SpikeConfiguration class is used to configure the feature.

Spike

The spikes can be configured with the following options:

Option Type Description
centerX (optional in Json, defaults to 0) int The x coordinate of the center of the spike.
centerZ (optional in Json, defaults to 0) int The z coordinate of the center of the spike.
radius (optional in Json, defaults to 0) int The radius of the spike.
height (optional in Json, defaults to 0) int The height of the spike.
guarded (optional in Json, defaults to false) boolean Whether iron bars should be placed around the end crystal

The SpikeFeature.EndSpike class is used to configure the spikes in code.

Examples

As an example, here's the configured feature used to place the default end spikes on the main island:

ConfiguredFeatures.kt
val END_SPIKE = FeatureRegistry.registerConfiguredFeature(
    Machines,
    "end_spike",
    Feature.END_SPIKE,
    SpikeConfiguration(false, emptyList(), null) // (1)!
)
  1. Since Minecraft only needs the default end spikes, we don't need to configure anything. false means that the crystals on top of the end spikes should not be invulnerable and null is the crystal beam target.
configured_feature/end_spike.json
{
  "type": "minecraft:end_spike",
  "config": {
    "crystal_invulnerable": false,
    "spikes": [] // (1)!
  }
}
  1. Since Minecraft only needs the default end spikes, we don't need to configure anything.
Example with a filled array
ConfiguredFeatures.kt
val END_SPIKE = FeatureRegistry.registerConfiguredFeature(
    Machines,
    "end_spike",
    Feature.END_SPIKE,
    SpikeConfiguration(
        false, // (1)!
        listOf(
            Spike(42, 0, 2, 82, true), // (2)!
            Spike(33, 24, 4, 94, false),
            Spike(12, 39, 5, 103, false),
            Spike(-13, 39, 2, 79, true),
            Spike(-34, 24, 4, 97, false),
            Spike(-42, -1, 3, 88, false),
            Spike(-34, -25, 3, 91, false),
            Spike(-13, -40, 3, 85, false),
            Spike(12, -40, 4, 100, false),
            Spike(33, -25, 2, 76, false)
        ),
        null // (3)!
    )
)
  1. Don't make the crystals invulnerable.
  2. The first spike is at the coordinates 42, 0 with a radius of 2 and a height of 82. true specifies that iron bars should be placed around the end crystal.
  3. Don't specify any specific target for the crystal beam.

  1. Most of the placement logic is handled by the feature itself. The only thing we need to do is to specify that the feature should only be placed in biomes that have end spikes.
