[SOLVED] some problem with custom elements mc 1.15.2

Hi i try to make two custom element one of them for handling animations from geckolib and on other for handling movment with tryToMoveXYZ method .

in game when i run the cods sometimes both work sometimes just one of them works and there is no error ,

this is my first cod

@SteveModElements.ModElement.Tag
public class AnimManeger extends SteveModElements.ModElement {


	public AnimManeger(SteveModElements instance) {
		super(instance, 24);
	}


	

	public static void animrep (String contoller , String animid , int repeat  ){
		IWorld world = (IWorld) Variables.world; //came from player entity 
		
		double xcor = Variables.xos;  //came from other method
		double ycor = Variables.yos;
		double zcor = Variables.zos;
		
		if ((((Entity) world.getEntitiesWithinAABB(SteveEntity.CustomEntity.class,
				new AxisAlignedBB((xcor) - (4 / 2d), (ycor) - (4 / 2d), (zcor) - (4 / 2d),  (xcor) + (4 / 2d), (ycor) + (4 / 2d), (zcor) + (4 / 2d)),
				null).stream().sorted(new Object() {
					Comparator<Entity> compareDistOf(double _x, double _y, double _z) {
						return Comparator.comparing((Function<Entity, Double>) (_entcnd -> _entcnd.getDistanceSq(_x, _y, _z)));
					}
				}.compareDistOf((xcor), (ycor), (zcor))).findFirst().orElse(null)) != null)) {
			if (((Entity) world.getEntitiesWithinAABB(SteveEntity.CustomEntity.class, new AxisAlignedBB((xcor) - (4 / 2d), (ycor) - (4 / 2d),
					(zcor) - (4 / 2d), (xcor) + (4 / 2d), (ycor) + (4 / 2d), (zcor) + (4 / 2d)), null).stream().sorted(new Object() {
						Comparator<Entity> compareDistOf(double _x, double _y, double _z) {
							return Comparator.comparing((Function<Entity, Double>) (_entcnd -> _entcnd.getDistanceSq(_x, _y, _z)));
						}
					}.compareDistOf((xcor), (ycor), (zcor))).findFirst().orElse(null)) instanceof IAnimatedEntity) {
				new Object() {
					@OnlyIn(Dist.CLIENT)
					void playAnimation(Entity entity, String animationID) {
						IAnimatedEntity aniEntity = (IAnimatedEntity) entity;
						aniEntity.getAnimationManager().get(contoller)
								.setAnimation(new AnimationBuilder().addRepeatingAnimation(animationID, (repeat)));
					}
				}.playAnimation(
						((Entity) world
								.getEntitiesWithinAABB(SteveEntity.CustomEntity.class, new AxisAlignedBB((xcor) - (4 / 2d), (ycor) - (4 / 2d),
										(zcor) - (4 / 2d), (xcor) + (4 / 2d), (ycor) + (4 / 2d), (zcor) + (4 / 2d)), null)
								.stream().sorted(new Object() {
									Comparator<Entity> compareDistOf(double _x, double _y, double _z) {
										return Comparator.comparing((Function<Entity, Double>) (_entcnd -> _entcnd.getDistanceSq(_x, _y, _z)));
									}
								}.compareDistOf((xcor), (ycor), (zcor))).findFirst().orElse(null)),
						(animid));
			}
		}


	}
}

and the second one exactly look like this except for this parts

if(steve!=null){
					CreatureEntity creature =(CreatureEntity) steve ;
        			creature.getNavigator().tryMoveToXYZ(xd , yd , zd, speed);
				}

why when i want to us them in same time in a same method , some times both work but some times just on of them work ?

please help!
