So i want to make an shootable entity like f. eks. the EntityArrow, but i want the entity to heal an living entity onImpact

 

Thought that this would work

 

 

 

 

@Override

protected void onImpact(MovingObjectPosition movingobjectposition) {

        if (movingobjectposition.entityHit instanceof EntityLivingBase) {

EntityLivingBase entity= (EntityLivingBase)movingobjectposition.entityHit;

        entity.heal(4.0F);

        }

}

 

 

 

Sadly it didn't

Thought that this would work

 

 

 

 

@Override

protected void onImpact(MovingObjectPosition movingobjectposition) {

        if (movingobjectposition.entityHit instanceof EntityLivingBase) {

EntityLivingBase entity= (EntityLivingBase)movingobjectposition.entityHit;

        entity.heal(4.0F);

        }

}

 

 

 

Sadly it didn't

 

Look at the EntityArrow class, there is an example, when the arrow is burning and hits a entity, the entity will be set on fire just look at that and you'll understand.

 

 

@Override

protected void onImpact(MovingObjectPosition movingobjectposition) {

if (movingobjectposition.entityHit instanceof EntityLiving) {

 

        movingobjectposition.entityHit.setFire(seconds);

        }

}

 

 

Not even close, there are no methods that heals in that class

Could i get more help?

 

How would i write that code?

 

This and that my mod is crashing in multiplayer are the only things i need to know to make my mod finally finished. I do not have the time to learn java just to call this code.

 

Could you just show how please?

I tried this but did not work

 

 

 

  @Override

  protected void onImpact(MovingObjectPosition movingobjectposition) {

        if (movingobjectposition.entityHit instanceof EntityLivingBase) {

        EntityLivingBase entity= (EntityLivingBase)movingobjectposition.entityHit;

        entity.heal(4.0F);

        }

  }

 

read the crash log and u will realize that u dont necessarily hit an entity so it can be null

There is no crash log, but i take the advice

 

 

 

  @Override

  protected void onImpact(MovingObjectPosition movingobjectposition) {

          if (movingobjectposition.entityHit != null)

          {

              if (movingobjectposition.entityHit instanceof EntityLivingBase) {

              EntityLivingBase entity= (EntityLivingBase)movingobjectposition.entityHit;

              entity.heal(4.0F);

              }

          }

  }

 

There is no crash log, but i take the advice

 

 

 

  @Override

  protected void onImpact(MovingObjectPosition movingobjectposition) {

          if (movingobjectposition.entityHit != null)

          {

              if (movingobjectposition.entityHit instanceof EntityLivingBase) {

              EntityLivingBase entity= (EntityLivingBase)movingobjectposition.entityHit;

              entity.heal(4.0F);

              }

          }

  }

 

 

Remove it, I realized diesieben is right and I missed a part. If your mod is crashing in mp only your proxies are probbly broken

I have worked hours with this mod and everything works except those two things. I really do not want to read my 400 page java book just to call this code

 

Yeah I need to look over my guis and see if have done something wrong with my proxies

 

I only need help with this healing projectile entity

you wont learn java only from reading a book, even if it will help

I do not simply copy and paste codes, I learn from them.

If you want me to learn, show me how to call this code

Question tho - where exacly is your problem? Is it not healing or crashing?

 

@Override
protected void onImpact(MovingObjectPosition mop)
{
  if (mop != null)
  {
    if (mop.entityHit instanceof EntityLivingBase)
    {
      EntityLivingBase entity = (EntityLivingBase) mop.entityHit;
      entity.heal(4.0F);
    }
  }
}

 

This doesn't work?

 

Both calling a method

 

 

 

@Override

protected void onImpact(MovingObjectPosition movingobjectposition) {

      if (movingobjectposition.entityHit instanceof EntityLivingBase) {

      heal(movingobjectposition);

    }

}

 

public static void heal(MovingObjectPosition movingobjectposition) {

EntityLivingBase entity= (EntityLivingBase)movingobjectposition.entityHit;

    entity.heal(4.0F);

}

 

 

And simply just

 

 

@Override

protected void onImpact(MovingObjectPosition movingobjectposition) {

      if (movingobjectposition.entityHit instanceof EntityLivingBase) {

      EntityLivingBase entity= (EntityLivingBase)movingobjectposition.entityHit;

    entity.heal(4.0F);

    }

}

 

 

Does not heal a living entity

Instead of healing I do entity.setDead

I also downloaded the damage indicators mod.

Testing on zombies(although they are not "living")

 

I would clearly know if it works

Seems that sometimes when i shoot the entity, I get hit instead of what I aim at

I did some testing and it did heal, but only sometimes. When I movingobjectposition.entityHit.setFire, I was buring sometimes when I launched the entity. Guess this entity hits me first

Solved!
