Import Boolean from another Class

Question

I have a DataHolders class. It contains:

public static boolean hit;

In my other class theres:

public void onHit(ProjectileHitEvent event) {
    if (event.getHitEntity() != null || event.getHitBlock() != null) {
        DataHolders.hit = true;
    }
}

ProjectileHitEvent gets triggered when a Player hits something with a Projectile (Arrow)

In my last class:

public void onLaunch(ProjectileLaunchEvent event) {
    while (!DataHolders.hit) {
        //..............
    }
}

ProjectileLaunchEvent gets triggered when a Player launches the Projectile (Arrow)

I want to do something while the Projectile (Arrow) is in the air ( ProjectileLaunchEvent triggered but ProjectileHitEvent not). But when the Arrow hits something ( ProjectileHitEvent gets triggered and boolean hit becomes true ) the loop should stop but the while loop goes on. I've already tested if ProjectileHitEvent really gets triggered, it works but the loop doesn't.

Answer 1

check if DataHolders.hit is true/false.

public void onLaunch(ProjectileLaunchEvent event) {
    while (!DataHolders.hit) {
        System.out.println(DataHolders.hit);
        //..............
    }
}

If true

You should focus on setting DataHolders.hit properly

If false

Print the value before/after setting the value

public void onHit(ProjectileHitEvent event) {
    if (event.getHitEntity() != null || event.getHitBlock() != null) {
        System.out.println(DataHolders.hit);
        DataHolders.hit = true;
        System.out.println(DataHolders.hit);
    }
}

If the latter output is true then there is a problem with the class where public static boolean hit; exists.
