Setup

Start a new Spring Boot Project

A Spring Boot project can be created with the Spring Initializr or directly in Intellij or Spring Tools 4, which works with Eclipse, Visual Studio Code, and Atom IDE.

Add the Brobot Library as a Dependency

Maven:

    <dependency>
      <groupId>io.github.jspinak</groupId>
      <artifactId>brobot</artifactId>
      <version>1.0.1</version>
    </dependency>

Gradle:

    implementation 'io.github.jspinak:brobot:1.0.1' 

Note that Brobot works with Java version 14 or later. The full build.gradle file should look similar to this:

    plugins {
        id 'org.springframework.boot' version '2.6.2'
        id 'io.spring.dependency-management' version '1.0.11.RELEASE'
        id 'java'
    }
    
    group = 'com.example'
    version = '0.0.1-SNAPSHOT'
    sourceCompatibility = '14'
    
    configurations {
        compileOnly {
            extendsFrom annotationProcessor
        }
    }
    
    repositories {
        mavenCentral()
    }
    
    dependencies {
        implementation 'org.springframework.boot:spring-boot-starter'
        compileOnly 'org.projectlombok:lombok'
        annotationProcessor 'org.projectlombok:lombok'
        testImplementation 'org.springframework.boot:spring-boot-starter-test'
        implementation 'io.github.jspinak:brobot:1.0.1'
        /*
        There are some settings that can be changed in Sikuli and are not yet
        replicated in Brobot.  
         */
        implementation('com.sikulix:sikulixapi:2.0.5') {
            exclude group: 'org.slf4j', module: 'slf4j-nop'
        }
    }

Create Folders for Images

Create a folder called images.sikuli to hold the images used by your Brobot application to manipulate GUI elements.
Create a folder called labeledImages to store images captured by your Brobot application. This folder holds the output of your application.

The folder structure should look like this (the build folder will be created automatically if using Gradle):

Capture Images with the Sikuli IDE

Open the Sikuli IDE and in Sikuli, the folder 'images.sikuli'. Capture images from the screen with the following names:

To follow the tutorial to prepare mock runs, the captured images can be of anything. You can play around with the similarity score by clicking on an image that has been saved in the Sikuli IDE.

Preparing your Demo for Live Runs

If you also wish to do live runs with the demo, you'll have to save these specific images in the game:

This will be "Castle of" or "Castillo de", etc., depending on the language setting.

The cutouts don't have to be exactly the same, just as close as possible. Keep in mind that Brobot will look for the exact size; if you resize the emulator you will have to cut and save the images again. In a production Brobot application you should have code that checks the position and size of the application window (here, the emulator) and resizes and repositions it if necessary.
