You gotta make a custom firework entity.
Or you can just

Code:java

for(LivingEntity en : <firework>.getWorld().getEntitiesByClass(LivingEntity.class)){
if(en.getLocation().distance(<firework>.getLocation()) <= 3)//or your distance{
en.damage(3);
}
}
 

 

If you are able to get the location of the firework when it explodes, you can get al the entities near it, and apply damage to them

Code:

final Firework firework = ...;
new BukkitRunnable(){public void run(){
if(!firework.isValid){
this.cancel();
// Firework just exploded
final double damage = 20; // Kill a player when he is standing inside the boom
final int range = 5; // 5 block range


final int squaredRange = range*range;
double distance;
final Location loc = firework.getLocation();
for(Entity entity : firework.getWorld().getEntities()){if(entity instanceof LivingEntity){
if((distance = entity.getLocation().distanceSquared(loc)) < squaredRange)
{
if(distance < 1) distance=1;
double damageModifer = ((squaredDistance - distance) / squaredRange) / 100; // This calculation may be better.... (it should apply less damage to the player if he is further away
double toDamage = damage*damageModifer;
assert damage >= toDamage;
((LivingEntity)entity).damage(toDamage);
}
}}
}}.runTaskTimer(plugin,1,1);

 

ferrybig I'm not good at coding this is my code for the firework can you say em how to add the damage

Code:

                Block b = player.getTargetBlock(null, 50);
                double x = b.getX();
                double y = b.getY();
                double z = b.getZ();
                Firework fw = (Firework) player.getWorld().spawn(b.getLocation(), Firework.class);
                FireworkEffect effect = FireworkEffect.builder().trail(true).flicker(true).withColor(Color.BLACK).withFade(Color.ORANGE).with(Type.BALL_LARGE).build();
                FireworkMeta fwm = fw.getFireworkMeta();
                fwm.clearEffects();
                fwm.addEffect(effect);
                Field f;
                try {
                        f = fwm.getClass().getDeclaredField("power");
                        f.setAccessible(true);
                        f.set(fwm, -2);
                } catch (NoSuchFieldException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                } catch (SecurityException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                } catch (IllegalArgumentException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                } catch (IllegalAccessException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                }
         
         
                fw.setFireworkMeta(fwm);

i got you on skype and i'm making a sort of empirewand with this

 

I thought you had a firework rocket, in this case, its simple to add a damage, at the following to the end of the code you send:

Code:

final double damage = 20; // Kill a player when he is standing inside the boom
final int range = 5; // 5 block range


final int squaredRange = range*range;
double distance;
final Location loc = firework.getLocation();
for(Entity entity : firework.getWorld().getEntities()){if(entity instanceof LivingEntity){
if((distance = entity.getLocation().distanceSquared(loc)) < squaredRange)
{
if(distance < 1) distance=1;
double damageModifer = ((squaredDistance - distance) / squaredRange) / 100; // This calculation may be better.... (it should apply less damage to the player if he is further away
double toDamage = damage*damageModifer;
assert damage >= toDamage;
((LivingEntity)entity).damage(toDamage);
}
}

 

ferrybig i get an error by squared distance please help me how to fix it

 

superjesse07 inside my code, I talked about firework, can you change it to fw?
also, what is the exact error message you get?

 

hi

 

ferrybig It Works Already Thanks To TryB4
