# Custom Block Integrations

## Custom Block Integrations

SimplyMines can place custom blocks from any of the following texture/item plugins alongside vanilla Minecraft blocks, mixed in the same mine. Support for each is a soft-dependency — it's detected automatically at startup if the plugin is present.

* [ItemsAdder](/simplymines-docs/introduction/features/itemsadder.md) — custom blocks via the ItemsAdder API.
* [Nexo](/simplymines-docs/introduction/features/nexo.md) — custom blocks with optional no-physics placement.
* [CraftEngine](/simplymines-docs/introduction/features/craftengine.md) — custom blocks with optional no-physics placement.

{% hint style="warning" %}
Detection happens once, on `onEnable`. If you install one of these plugins after SimplyMines has already started, restart the server (a `/reload` command is not sufficient) so SimplyMines can pick it up.
{% endhint %}

Custom blocks are configured per-mine in the block composition editor, alongside vanilla blocks — pick the block, set its weight/percentage, and (for supported integrations) whether it should skip physics updates on placement.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://simplymines.gitbook.io/simplymines-docs/introduction/features/custom-block-integrations.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
