First things first, I have two classes (EntityTear.class and EntityThrowable.class) which I coppied straight from the Minecraft src, EntityTear was EntitySnowball. I've been looking through the 2 classes and can't figure out a way to limit how fast the item is used. What I want is maybe a second delay inbetween each item use so the entity is fired slower. My code:
EntityTear.class:

}

par1MovingObjectPosition.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), (float)Damage);
}

Secondly, I'm looking for a way to increase or decrease the player walking speed and maybe possibly stop the player from being able to run. If I can't stop the player running, maybe also limit the running speed. If anyone has any ideas about any of these issues, I would greatly appreciate some help. Many thanks, Tom.
