Is there a way to modify Base Classes with out directly changing them?

 

I think you can by using Java Reflections

What are Java Reflections exactly?

Java reflecting is a way to bypass class and security restrictions in java.

 

It depends on 'what' you want to change as to whether reflections will work or not.

What I am wanting to change is part of the MovingObjectPosition

 

 

package net.minecraft.src;

public class MovingObjectPosition
{
    /** What type of ray trace hit was this? 0 = block, 1 = entity */
    public EnumMovingObjectType typeOfHit;

    /** x coordinate of the block ray traced against */
    public int blockX;

    /** y coordinate of the block ray traced against */
    public int blockY;

    /** z coordinate of the block ray traced against */
    public int blockZ;

    /**
     * Which side was hit. If its -1 then it went the full length of the ray trace. Bottom = 0, Top = 1, East = 2, West
     * = 3, North = 4, South = 5.
     */
    public int sideHit;

    /** The vector position of the hit */
    public Vec3D hitVec;

    /** The hit entity */
    public Entity entityHit;
    
    /** Used to determine what sub-segment is hit */
    public int subHit = -1;

    public MovingObjectPosition(int par1, int par2, int par3, int par4, Vec3D par5Vec3D)
    {
        this.typeOfHit = EnumMovingObjectType.TILE;
        this.blockX = par1;
        this.blockY = par2;
        this.blockZ = par3;
        this.sideHit = par4;
        this.hitVec = Vec3D.createVector(par5Vec3D.xCoord, par5Vec3D.yCoord, par5Vec3D.zCoord);
    }

    public MovingObjectPosition(Entity par1Entity)
    {
        this.typeOfHit = EnumMovingObjectType.ENTITY;
        this.entityHit = par1Entity;
        this.hitVec = Vec3D.createVector(par1Entity.posX, par1Entity.posY, par1Entity.posZ);
    }
}

 

 

I want the line

public Entity entityHit;

to be

public static Entity entityHit;

 

Would that be possible?

Do you know exactly what static does... ?

No... and the code i was using gave me some unexpected results... so no longer need it

A bit of a tip here: You should put your code down. Go learn Java, make a few test programs, follow some tutorials, and then pick your code back up again.
