Accessing protected variables in net.minecraft.src?


DrZhark

Recommended Posts

As I'm porting my mod to Forge, the mod now has its own package

 

package.drzhark.mocreatures;
import net.minecraft.src.*;

 

There are many places in my code where I need to access or change the value of a protected variable, i.e

entitymob.entityToAttack in the following method:

 

public static void repelMobs(Entity entity1, Double dist, World worldObj)
{
	List list = worldObj.getEntitiesWithinAABBExcludingEntity(entity1, entity1.boundingBox.expand(dist, 4D, dist));
        for(int i = 0; i < list.size(); i++)
        {
        	Entity entity = (Entity) list.get(i);
            if(!(entity instanceof EntityMob))
            {
                continue;
            }
            EntityMob entitymob = (EntityMob) entity;
          
  entitymob.entityToAttack = null;
            entitymob.setPathToEntity(null);
        }
}

 

However that variable entityToAttack is now unaccessible from my package, as it is a protected variable that does not have a Getter/Setter.  Is there a way around this?  I guess it could be done with reflection (which I'm not too familiar with). Or if there is an easier way, I'm all ears. Thanks in advance!

A child class of a base class can always access the protected members of that base class.

Reflection can access other protected vars, but has a speed cost.

If you ever need to do it in a speed sensitive area of code (hundreds of times in a tight loop for example), then submit a patch to have forge change it to public.

 

There are a few other things, but that is the gist.
