Can't launch creeper

I can't launch a creeper on entitybowshoot. My code:
İt gives error on "o.launchProjectile(creeper);"

Code:

if (o.hasPermission("bow.use.creeperbow")){
                  e.setCancelled(true);
              Entity creeper = o.getWorld().spawnEntity(o.getLocation(), EntityType.CREEPER);
              creeper.setVelocity(e.getProjectile().getVelocity());
              o.launchProjectile(creeper);
              }

 

Because creeper isn't a projectile.

 

Exacly what @FisheyLP siad^
If you want toi launch a creeper you need to set it's velocity to some vector dependin on the direction you wana shoot it.

 

@mine-care @FisheyLP
I already setted Velocity in
creeper.setVelocity(e.getProjectile().getVelocity());
?

 

@Krumb069 But you're still trying to launch a creeper. That's not possible with the method you're trying, because a creeper is not a Projectile.

 

@AdamQpzm
So how can I throw a creeper ?

 

@Krumb069 Remove the launchProjectile line. I don't know why you have it there.
