## Upgrading from API v7

The changes from the previous API version are as follows:

- The following events have been added:
```java
CoreProtectPreLogEvent
``` 
  
---

## Getting Started

Ensure you're using CoreProtect 20.2 or higher. Add it as an external jar to your plugin in your IDE.  
Alternatively, if using Maven, you can add it via the repository [https://maven.playpro.com](https://maven.playpro.com) (net.coreprotect, 20.2).

The first thing you need to do is get access to CoreProtect. You can do this by using code similar to the following:

```java
import net.coreprotect.CoreProtect;
import net.coreprotect.CoreProtectAPI;

private CoreProtectAPI getCoreProtect() {
        Plugin plugin = getServer().getPluginManager().getPlugin("CoreProtect");
     
        // Check that CoreProtect is loaded
        if (plugin == null || !(plugin instanceof CoreProtect)) {
            return null;
        }

        // Check that the API is enabled
        CoreProtectAPI CoreProtect = ((CoreProtect) plugin).getAPI();
        if (CoreProtect.isEnabled() == false) {
            return null;
        }

        // Check that a compatible version of the API is loaded
        if (CoreProtect.APIVersion() < 8) {
            return null;
        }

        return CoreProtect;
}
``` 

With this code, you can then access the API with a call like the following:

```java
CoreProtectAPI api = getCoreProtect();
if (api != null){ // Ensure we have access to the API
  api.testAPI(); // Will print out "[CoreProtect] API test successful." in the console.
}
``` 

Yay, you're now using the CoreProtect API!

### Examples

- Get the last 60 seconds of block data for the user "Notch".
```java
CoreProtectAPI CoreProtect = getCoreProtect();
if (CoreProtect!=null){ //Ensure we have access to the API
  List<String[]> lookup = CoreProtect.performLookup(60, Arrays.asList("Notch"), null, null, null, null, 0, null);
  if (lookup!=null){
    for (String[] result : lookup){
      ParseResult parseResult = CoreProtect.parseResult(result);
      int x = parseResult.getX();
      int y = parseResult.getY();
      int z = parseResult.getZ();
      // ...
    }
  }
}
``` 

---

- Get the last 60 seconds of block data for the user "Notch", excluding dirt and grass blocks.
```java
CoreProtectAPI CoreProtect = getCoreProtect();
if (CoreProtect!=null){ //Ensure we have access to the API
  List<Object> exclude = Arrays.asList(Material.DIRT, Material.GRASS);
  List<String[]> lookup = CoreProtect.performLookup(60, Arrays.asList("Notch"), null, null, exclude, null, 0, null);
  if (lookup!=null){
    for (String[] value : lookup){
      ParseResult result = CoreProtect.parseResult(value);
      int x = result.getX();
      int y = result.getY();
      int z = result.getZ();
      // ...
    }
  }
}
``` 

---

- Get the last 60 seconds of block data within 5 blocks of a location.
```java
CoreProtectAPI CoreProtect = getCoreProtect();
if (CoreProtect!=null){ //Ensure we have access to the API
  List<String[]> lookup = CoreProtect.performLookup(60, null, null, null, null, null, 5, location);
  if (lookup!=null){
    for (String[] value : lookup){
      ParseResult result = CoreProtect.parseResult(value);
      int x = result.getX();
      int y = result.getY();
      int z = result.getZ();
      // ...
    }
  }
}
``` 

---

- Rollbacks / restores use the same code structure as the above examples. For example:
```java
class BasicThread implements Runnable {
@Override
public void run() {
  try {
    CoreProtectAPI CoreProtect = getCoreProtect();
    if (CoreProtect!=null){ //Ensure we have access to the API
      List<String[]> lookup = CoreProtect.performRollback(60, Arrays.asList("Notch"), null, null, null, null, 0, null);
      if (lookup!=null){
        for (String[] value : lookup){
          ParseResult result = CoreProtect.parseResult(value);
          int x = result.getX();
          int y = result.getY();
          int z = result.getZ();
          // ...
        }
      }
    }
  }
  catch (Exception e){
    e.printStackTrace(); 
  }
}
}
Runnable runnable = new BasicThread();
Thread thread = new Thread(runnable);
thread.start();
``` 

---

- Check if the user "Notch" has already placed a block at a location within the last 60 seconds.
```java
CoreProtectAPI CoreProtect = getCoreProtect();
if (CoreProtect!=null){ //Ensure we have access to the API
  boolean hasPlaced = CoreProtect.HasPlaced("Notch", block, 60, 0);
}
``` 

---

- Get the last 60 seconds of block data for a specific block.
```java
CoreProtectAPI CoreProtect = getCoreProtect();
if (CoreProtect!=null){ //Ensure we have access to the API
  List<String[]> lookup = CoreProtect.blockLookup(block, 60);
  if (lookup!=null){
    for (String[] result : lookup){
      ParseResult parseResult = CoreProtect.parseResult(result);
      int x = parseResult.getX();
      int y = parseResult.getY();
      int z = parseResult.getZ();
      // ...
    }
  }
}
``` 

---

- Log the placement of a block at a location by the user "Notch".
```java
CoreProtectAPI CoreProtect = getCoreProtect();
if (CoreProtect!=null){ //Ensure we have access to the API
  boolean success = CoreProtect.logPlacement("Notch", block.getLocation(), block.getType(), block.getData());
}
``` 

---

- Log adding/remove items in a chest (or some other block inventory).
```java
CoreProtectAPI CoreProtect = getCoreProtect();
if (CoreProtect!=null){ //Ensure we have access to the API
  boolean success = CoreProtect.logContainerTransaction("Notch", inventory.getLocation());
  // modify your container contents immediately after (e.g. [i]inventory.addItem(itemStack);[/i])
}
``` 

---

- Perform a multi-threaded placement check to see if the user "Notch" has already placed a block at a location within the last 60 seconds. This ignores the most recent 1 second of logged data, to account for the fact that that new block data may have already been logged, depending on your code.
```java
final Block block = null; //Should be an actual block
class BasicThread implements Runnable {
  @Override
  public void run() {
    try {
      CoreProtectAPI CoreProtect = getCoreProtect();
      if (CoreProtect!=null){ //Ensure we have access to the API
        boolean hasPlaced = CoreProtect.hasPlaced("Notch", block, 60, 1);
      }
    }
    catch (Exception e){
      e.printStackTrace(); 
    }
  }
}
Runnable runnable = new BasicThread();
Thread thread = new Thread(runnable);
thread.start();
```
