# TickEvent

TickEvent is an event that is fired twice Minecraft tick - once at the start, and once at the end. Minecraft ticks happen once every 50ms, or 20 times per second.

You can specify when you want this to be fired using `Stage`, like this:

```java
@Subscribe
public void onTick(TickEvent event) {
    if(event.stage == Stage.START) {
        // do something at the start of the tick
    }
    if(event.stage == Stage.END) {
        // do something at the end of the tick.
    }
}
```

If the Stage of the event is not checked, your code may run twice. Be careful!

## 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://docs.polyfrost.org/oneconfig/events/available-events/tickevent.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.
