• Our annual EV3 Summer Camp is going virtual this year!
• Focusing on the fundamentals of EV3 robots and CAD skills to prepare you for the new season during Pandemic
• EV3: Weeknights (7/27-7/30) 7-10pm; Saturday (8/1) 9am-5pm
• CAD: Sunday (8/2) 9am-4pm
• EV3 sessions will be taught by TechnicBots (FTC 8565) with support from ACP FTC 18227 and ACP FLL 50661
• CAD sessions will be taught by ACP FLL 40657
• Register here by 7/25/2020
• This is a fundraising event, all profits will go towards teaching teams' robotics fund of next season

RoboCode Virtual Battle

Eclipse Check In & Developing Tips

• We highly recommend you have Eclipse installed as it offers a much more streamlined coding experience. Instructions were sent out in the email and you can find them again here (same doc as install instructions last time)

https://robowiki.net/wiki/Robocode/Eclipse

• Brief General Overview
• Nice little intro to Java: https://www.slideshare.net/intelligotech/java-tutorial-ppt-7189933
• Some quick general coding tips
• Keep class name the same as your file name and make sure it is descriptive
• Look through error messages to try and figure out problems in code. If you are stuck, try looking up the exact text of the error message online!
• Make sure to have imported a library before you use it: more on that later

Targeting: Revenge

• With four bots in the field on each tournament, it’s tricky to determine who you want to target!
• Revenge targeting is a simple technique where you try to shoot the robot that shot you last
• The idea is that if you take out the robots that are targeting you, you will take less damage

Storing the name

To fire at the robot who hit us last, we need to store its name in a variable

String RevengeTarget;

//This will store the name of the person who hit us last so we know who to shoot at

​

Getting the target

• We want to update the value of RevengeTarget whenever we get hit
• We can do this with the OnHitByBulletEvent()

public void onHitByBullet(HitByBulletEvent e) {

RevengeTarget = e.getName();

}

​

Shooting at the target

• Now all we need to do is shoot when we see the robot with the same name as RevengeTarget
• public void onScannedRobot(ScannedRobotEvent e) {

if(e.getName().equals(RevengeTarget)){

fire(3);

}

}

​

Sharing Robot Insights

• We are all in this to learn about coding together, and even though it’s fun to get competitive in our tournaments, keep in mind our overall goal is still to teach everyone as much as we can.
• With that in mind, the winner of each division’s tournament is expected to share some thoughts about their code and the thought that went into their robot (By submitting the code, you agree to show your code to others)
• If you are confident in your robot, make sure to think about what you are going to say if you win.
• Good luck everyone!
