Hi,

i have a pet that follows the player around and goes to a specific location on right click. I don't want it to teleport so i wrote a custom goal just to move there without teleporting:

entity.getNavigation().moveTo(x, y, z);

But the problem is, that it sometimes gets stuck somewhere, so I want to make custom pathfinding for the pet, but I have no idea where to start

minecraft has good path finding...
but if you want to make one create a Class extending PathNavigation

public class FlappingNavigation extends FlyingPathNavigation {
		public FlappingNavigation(Mob p_01_, Level p_02_) { super(p_01_, p_02_);
... } }

then on add on stats

public void setStartStat() {
        this.navigation = new FlyingPathNavigation(this, this.level);
... }

but i didnt change how it path find, i just adjusted how it detects Y, since it's flying (with gravity)
vanilla path find has a count on when it's stuck, when it is stuck it stops navi... (if that helps)

you could also change the ai by extending
 

static class WanderFloater extends WaterAvoidingRandomStrollGoal {
		public WanderFloater(TyFlyer p_01_, double p_02_) { super(p_01_, p_02_); }

@Nullable
		private Vec3 findPos() {
... } }

u can change how it finds the next position... maybe make it shorter???

sorry if it's already 2 days passed

orrrrr.  u can change Aistep
(maybe change how it walks to preventing getting stuck, like how the spider get stuck for being chunky)

 

public void aiStep() {... dont super .. do your walk/fly/swim}

 

you can also change the way probability of walking on certain blocks, 

public BbBird(EntityType<? extends PathfinderMob> p_35267_, Level p_35268_) {
      this.setPathfindingMalus(BlockPathTypes.DAMAGE_FIRE, -1.0F);
...}

Hi @spiritfilled,

i did it by overriding the customServerAIStep in my Entity and applying some changes to the Navigation, like recalculatePath, but thank you for your help :-)
