It’s time for 4 - Loops 😎
🔁 Repeating Actions with while Loops
A while loop lets your robot repeat actions as long as a condition is true — just like an if statement that keeps checking over and over.
while (getEnergy() > 50) {
forward(100);
back(100);
}This bot will move back and forth while it has energy above 50.
♾️ Infinite Loop for Main Behavior
Robocode bots often use an infinite while (true) loop for their main logic:
public void run() {
while (true) {
scan();
forward(50);
turnRight(30);
}
}This keeps the bot active for the entire round.
❗ Be Careful!
If the condition in your while loop never becomes false, it can go forever. That’s great for behavior loops, but not for checks that should eventually stop.
while (getGunHeat() > 0) {
turnGunRight(5); // Keep turning until gun is cool
}🧠 Think Like a Loop
- Start with a condition (like an
if) - Repeat what’s inside
{}until the condition is false
while (enemyCount > 0) {
scan();
fire(2);
enemyCount--;
}Looping ends when no enemies are left.
