Code examples

Easy to configure event listeners

IBlockUpdateListener - called when neighbour block is placed/removed

public class OnGrassBlockUpdate : MonoBehaviour, IBlockUpdateListener
{
    public BlockType GetBlockType()
    {
	    // Block type you want to listen for updates
        return BlockType.GRASS_BLOCK;
    }

    public void OnBlockUpdate(BlockEventData data, Dictionary<BlockFace, BlockEventData> neighbours, params int[] args)
    {
        // if above block is solid block
        if (WorldData.GetBlockState(neighbours[BlockFace.TOP].type) == BlockState.SOLID)
        {
            // replace current block with dirt in next update
            data.chunk.AddBlockToBuildList(data.position, BlockType.DIRT);
        }
    }
}

IBlockArrayDestroyListener - called when block is removed

public class OnAnyDestroy : MonoBehaviour, IBlockArrayDestroyListener
{
    public BlockType[] GetBlockTypes()
    {
        // register this event listener to all blocks
        return Utils.GetAllBlockTypes();
    }

    public void OnBlockDestroy(BlockEventData data, params int[] args)
    {
        BlockType type = data.blockType == BlockType.GRASS_BLOCK ? BlockType.DIRT : data.blockType;
        // instantiate particle at block position
        ParticleManager.InstantiateBlockDestroyParticle(ParticleType.BLOCK_DESTROY_PARTICLE, data.WorldPosition, type);
    }
}
