Simple Continuous Loop Class

[Camaro]

Here's a little class to help execute a self-contained loop under a certain condition

import org.osbot.rs07.Bot;
import org.osbot.rs07.event.Event;

import java.util.function.BooleanSupplier;
import java.util.function.IntSupplier;

public final class Loop extends Event {

    private final IntSupplier task;

    private final BooleanSupplier condition;

    private final int maxLoops;

    private int loopCounter = 0;

    /**
     * Public method to execute the loop
     *
     * @param bot the bot instance
     * @param task the task to continuously perform.
     *             Must return a number, representing the sleep time between loops
     * @param condition the condition signaling loop success and completion
     * @param maxLoops the maximum number of loops before declaring failure
     * @return true if the loop ended successfully

    public static boolean until(Bot bot, IntSupplier task, BooleanSupplier condition, int maxLoops) {
        Event loop = new Loop(task, condition, maxLoops);
        bot.getEventExecutor().execute(loop);
        return loop.hasFinished();
    }

    // Similar method to the above but with a default maxLoops
    public static boolean until(Bot bot, IntSupplier task, BooleanSupplier condition) {
        return until(bot, task, condition, 100);
    }

    // Similar method to the above but with sleep time given as a parameter
    public static boolean until(Bot bot, Runnable task, BooleanSupplier condition, int sleepTime,  int maxLoops) {
        IntSupplier taskWithReturn = () -> {
            task.run();
            return sleepTime;
        };
        return until(bot, taskWithReturn, condition, maxLoops);
    }

    // Similar method to the above but with default sleep time and max loops
    public static boolean until(Bot bot, Runnable task, BooleanSupplier condition) {
        return until(bot, task, condition, 600, 100);
    }

    private Loop(IntSupplier task, BooleanSupplier condition, int maxLoops) {
        this.task = task;
        this.condition = condition;
        this.maxLoops = maxLoops;
    }

    @Override
    public int execute() {
        if (loopCounter++ > maxLoops)
            // Too many loops, something went wrong, exit
            setFailed();
        else if (condition.getAsBoolean())
            // Condition successfully met, exit
            setFinished();
        else return task.getAsInt();
        return 0;
    }

}

// Drop all items in inventory
Loop.until(getBot(), () -> getInventory().interact("Drop", Objects::nonNull), inventory::isEmpty);

Gj.

I would perhaps replace IntSupplier with Runnable and just accept the additional sleep parameter.

This sounds and looks a lot like ConditionalLoop. Regardless nice release

Yeah, I could have extended ConditionalLoop instead of event, but it wouldn't be different internally because ConditionalLoop executes an event anyway.

 Either way, enables lambda expressions similar to the custom sleep methods that are around.
