I'm trying to create an entity that moves around on land like a normal entity, but also when it enters water, it swims smoothly in the water like the Guardian and have it attack entities on land and water. How am I to achieve this?

Well.. at first, I entirely copied the Guardian's code into the model, then I completely cleared it out since I was still working on the model for the entity at the time, so this is what I have so far

 

package common.zeroquest.entity;

import net.minecraft.entity.EntityAgeable;
import net.minecraft.entity.passive.EntityAnimal;
import net.minecraft.pathfinding.PathNavigateGround;
import net.minecraft.world.World;

import com.google.common.base.Predicate;

public class EntityRowarn extends EntityAnimal {

public EntityRowarn(World worldIn) {
	super(worldIn);
	this.setSize(0.6F, 2.6F);
	this.stepHeight = 1;
	((PathNavigateGround) this.getNavigator()).func_179688_b(true);
}

@Override
public EntityAgeable createChild(EntityAgeable ageable) {
	// TODO Auto-generated method stub
	return null;
}
}

Ok, I started coping code from the Guardian and resulted with this

By the way, many of those methods with difficult names like func_175447_b() actually now have human-readable names -- in this case getNavigator().

 

To update the SRG mappings, in your build.gradle file add a mappings reference. For example, in my current 1.8 mods my build.gradle includes the following:

    minecraft {

        version = "1.8-11.14.1.1410"

        runDir = "../run/assets"

        mappings = "snapshot_20150518"

    }

 

Then you need to run gradlew setupDecompWorkspace and gradlew eclipse again. Then your code will be easier to read.

 

Anyway, so you're making a good start. But I think the getNavigator() method should return different navigator depending on whether your entity is on land or water. Also, I'm not sure exactly how to get the land navigator to get into the water, so you may have to detect that you're close to the water then change navigator.

That helped me a good bit.. but I'm still trying to see what pieces of code I don't need, since the guardian has parameters for the elder, I want to remove those and only leave the nagavitor switching codes

It literally contradicts itself. Plus, there is no stack trace, pretty weird... does this happen even without your new entity's code?

Hey, how do I make the entity actually walk around first and only when it hits the water it swims like the Guardian?

That's the tricky part. Honestly, you shouldn't try creating a mod unless you already have an idea on how you will make it work...

 

Anyway, the first question is: when do you want it to enter the water?

 

The general idea would be that at the point it should go into water you'd have an AI task that would find the closest water and head to it. Then when you detect that the entity is actually in the water (I think there is a method like isInWater() or similar you can check) then you'd switch the navigator to swimming navigator.

 

When doing custom stuff it is best to look at how other vanilla mobs do similar things. For example I think a burning zombie will purposefully go into water. So check how the zombie AI does that, but change the condition (in your case  you don't have to be burning).

I want it to get into the water when it detects it's attacker in the water and get out of the water and stay near it during the day, then go into the water at night. I have been at the zombie's entity coding, specifically the ones that have it move through the villages
