trying to move an object with no script by accessing its rigidbody2d component.
I have a slime sprite that will instantiate and fire a slime ball. As stated above, I am trying to move the slime ball by using velocity on its rigidbody component. The problem is that it will only instantiate without moving at all. I am getting zero errors and am very puzzled as to why my code is not working.
private bool SpawnBall;
public GameObject SlimeBallAttack;
public float slimeballX;
public float slimeballY;
public float slimeballSpeed;
public float ballVerticality;
public SlimeBallMove ballVelocity;
void Start()
{
SlimeE = GetComponent<Rigidbody2D>();
SlimeAnim = GetComponent<Animator>();
currentEnemyState = EnemyState.Idle;
mySpriteRenderer = GetComponent<SpriteRenderer>();
risk = 0;
random = true;
}
void Attack()
{
InvokeRepeating("RandomValue", 1f, 1f);
}
private void RandomValue ()
{
risk = Random.Range(0, 11);
attackMeter += risk;
if (attackMeter >= 20 && SlimeAnim.GetInteger("SlimeAttack") == 1)
{
attackMeter = 0;
SpawnBall = true;
}
if (SpawnBall == true)
{
if(mySpriteRenderer.flipX == false)
{
Instantiate(SlimeBallAttack, new Vector2(gameObject.transform.position.x + slimeballX, gameObject.transform.position.y + slimeballY), gameObject.transform.rotation);
SlimeBallAttack.GetComponent<Rigidbody2D>().velocity = new Vector2(slimeballSpeed * Time.deltaTime, ballVerticality);
}
if (mySpriteRenderer.flipX == true)
{
Instantiate(SlimeBallAttack, new Vector2(gameObject.transform.position.x - slimeballX, gameObject.transform.position.y + slimeballY), gameObject.transform.rotation);
SlimeBallAttack.GetComponent<Rigidbody2D>().velocity = new Vector2(-slimeballSpeed * Time.deltaTime, ballVerticality);
}
SpawnBall = false;
}
NOTE: the Attack() function is in update and is only called if a certain condition passes. Also, I have tried putting the code to instantiate and move the object in update but it is only instantiating with no movement.
You're trying to use functions on the components attached to the Prefab, not the object you just instantiated. These are two different objects. Instantiate returns a GameObject, so just assign that to a temporary variable, then use your GetComponent and such on that.
GameObject newSlime = Instantiate<GameObject>(SlimeBallAttack, new Vector2(gameObject.transform.position.x + slimeballX, gameObject.transform.position.y + slimeballY), gameObject.transform.rotation);
newSlime.GetComponent<Rigidbody2D>().velocity = new Vector2(slimeballSpeed * Time.deltaTime, ballVerticality);
Thanks so much, that was exactly what was wrong. Now I understand prefabs better :D
