Tutorial How to create an area for the player to move too!

In this tutorial i will show you how too:

1. Create an Area
2. Select random Coordinate in area
3. Create a path to Coordinate
4. Walk there!

This came around as i wanted to find a random coordinate in the bank for my player to move to and then interact with the bank to make it more realistic than going to the same point every time!

1) Create an Area
I'm going to do it in terms of a bank but you can change it to your needs!
To create and area, in a way just copy me:

Code (Text):

1. final Area bank = new Area.Rectangular(new Coordinate(xxxx, xxxx, 0), new Coordinate(xxxx, xxxx, 0)); // Bank area

To find the Coordinates use the Area maker or this one!

2.) Select random Coordinate in area
Ok so this is easy once you know what you are doing!

Code (Text):

1. final Coordinate destination = bank.getRandomCoordinate();

Simple as that, just make sure "bank." is the same as what you defined the Area to be.

3.) Create a path
Next you need to create a path you can use what you want, a Bresenham Path or a Region Path i prefer a region path as my bank is close by!
As "Baddest Man on Earth" pointed out:

• RegionaPath can only be generated if the destination is in the current loaded Region. You should always have a failsafe BreshnamPath or WebPath

So make sure you take this into acount!

Code (Text):

1. final RegionPath pathtobank = RegionPath.buildTo(destination); // Sets path

For a Bresenham Path just replace "RegionPath" with "BresenhamPath"

4.) Walk There!
This is the easiest part!

Code (Text):

1. if (pathtobank != null)
2.                 pathtobank.step(true); // goes to the bank

Just a null check to see if it fails and then it walks there!

All the code together looks like this:

Code (Text):

1. final Area bank = new Area.Rectangular(new Coordinate(xxxx, xxxx, x), new Coordinate(xxxx, xxxx, x)); // Bank area
2.  
3.         if (!Bank.isOpen()) { // Check if bank is open
4.      
5.             final Coordinate destination = bank.getRandomCoordinate(); // Gets random Coordinate in area
6.             final RegionPath pathtobank = RegionPath.buildTo(destination); // Sets path
7.             if (pathtobank != null)
8.                 pathtobank.step(true); // goes to the bank
9.        
10.         }

Hope this has helped anybody that needed it! If you have any questions ask away!

 

Added the thing about the Region Path, in the main Post, But realistically you should make sure it is all reachable!
