i want to make a npc follow my player but can't seem to get the position of the player inside the script of my npc.
i tried GetNode<player>("player"); And Getnode("player") as player; ( in C#)
but i get node not found but its there :(my scene looks like this: * World: 1. tiles 2. player 3. npc
i don't want to place the npc as child of player because i want to make the npc move only if player is to faraway and make him catch up to the player .
You have to give it a path to the player. If can be in any node in the tree, that is fine, but the code will depend on if it's a child, or sibling, or parent, or something else. This page may be helpful.
https://docs.godotengine.org/en/stable/classes/class_nodepath.html
in change the path to ../player the error is gone but code dont work player.position is empty?
here is the code to make npc move
public override void _Ready()
{
playerObject = GetNode("../player") as player; //Get the player
}
private void Move(){
if(playerObject.Position != null) //Test print to check if position has a value.
GD.Print(playerObject.Position);
Vector2 direction = playerObject.Position - this.Position; // to check position of the player if negatief player is left
Vector2 distanceBetween = new Vector2(Math.Abs(playerObject.Position.x - this.Position.x), //check distance between player and npc
Math.Abs(playerObject.Position.y - this.Position.y));
if(distanceBetween > maxDistance){ /* check if the distance between player
and npc is not greater than max ditance */
if(direction.x < 0){
speed -= speed;
motion.x = Math.Max(-maxSpeed, -speed); //speed up to maxspeed
}
else{
speed += speed;
motion.x = Math.Min(maxSpeed, speed); //speed up to maxspeed
}
}
else{
motion.x = Mathf.Lerp(motion.x, 0, 0.3f); // to stop npc
}
}
public override void _PhysicsProcess(float delta){
motion = MoveAndSlide(motion);
}Ok my bad i forgot to update Move() every frame :3 also i wil post the code again so if somebody look this up don't just copy it the don't get wrong outputs , there are some errors in the code that makes the npc disappear because its position becomes NAN :#
private void Move(){
Vector2 distanceBetween = playerPosition.GetCurrentPosition() - this.Position;
if(Math.Abs(distanceBetween.x) > maxDistance.x){ /* check if the distance between player
and npc is not greater than max ditance */
//GD.Print(distanceBetween);
if(distanceBetween.x < 0){
motion.x = Mathf.Lerp(motion.x, -maxSpeed, 0.1f); //speed up to maxspeed
}
else{
motion.x = Mathf.Lerp(motion.x, maxSpeed, 0.1f); //speed up to maxspeed
}
}
else{
motion.x = Mathf.Lerp(motion.x, 0, 0.1f); // to stop npc
}
if (Math.Abs(distanceBetween.y) > maxDistance.y)
{
if (distanceBetween.y < 0)
motion.y = Mathf.Lerp(motion.y, -maxSpeed, 0.2f);
else
motion.y = Mathf.Lerp(motion.y, maxSpeed, 0.2f);
}
else
motion.y = Mathf.Lerp(motion.y, 0, 0.2f);
}
