Making players bleed

I would like to make it so when a player is hit, he has a 50 percent change of bleeding. The bleeding would give the player 1 damage every 20 ticks. How would I go about doing this?

This is my *failed* attempt

Code:

    @EventHandler (priority= EventPriority.NORMAL)
   
    public void onEntityDamageEvent(final EntityDamageEvent e) {
 
        if (plugin.getConfig().getBoolean("bleeding.enabled")) {
            if (e.getCause() == DamageCause.ENTITY_ATTACK) {
                double c = random.nextDouble();
                c = random.nextDouble();
                c = random.nextDouble();
                if (c  <= ((plugin.getConfig().getDouble("bleeding.chance"))/100)) {
                    this.plugin.getServer().getScheduler().scheduleSyncDelayedTask(this.plugin, new Runnable() {
                        public void run() {
                            p.damage(1);
                        }
                    }, 20L);
 
                }
            }
        }

 

Why are you generating a random number 3 times? This looks like it should work, you should do testing by printing a message whenever it fails one of the if statements.

 

Make bleeding.chance a number 0-100 and remove the /100.
Then in nextDouble() put the number 100 in between parentheses.

 

Are you given an error in the log?

Maybe you are just really lucky and you always got the 50% chance of not bleeding.
