I am having an issue with Instantiate.

`
// ************************** Shoot Logic *********************************

		// make sure we have ammo and the shoot is not on cooldown
		if(Ammo > 0 && shootTimer <= 0)
		{
			// shoot timer is reset so it's ok to fire.
			if(Input.GetButtonUp("Fire1"))
			{
				Ammo = -1;
				shootTimer = 1.0f;	
				Vector2 direction; // direction the player is facing
				Vector2 gunPos; // position of the Gun on the player
				// which direction is the player travelling / facing?
				if(Input.GetAxis(axisName) < 0)
				{
					// set the direction the bullet will travel to left
					direction = -Vector2.right;
					gunPos = new Vector2 (GameObject.FindGameObjectWithTag("Gun").transform.position.x - 1, // + 1 to stop the bullet from hitting the player
					                      GameObject.FindGameObjectWithTag("Gun").transform.position.y);
				}	
				else
				{	// set the direction the bullet will travel to right
					direction = Vector2.right;
					gunPos = new Vector2 (GameObject.FindGameObjectWithTag("Gun").transform.position.x + 1, // + 1 to stop the bullet from hitting the player
					                      GameObject.FindGameObjectWithTag("Gun").transform.position.y);
				}
				// set the bullet to "face" the same direction as the player
				Quaternion quaternionDirection = Quaternion.LookRotation(direction);
				// spawn the bullet
				Instantiate(bullets,gunPos, quaternionDirection);
			}
		}
		else
		{
			// bullet is on Cooldown so let's reflect the passage of time in the timer
			shootTimer -= Time.deltaTime;
		}

The issue is that bullets are not rendering in the Scene or Game views. When I drag the prefab into the scene it renders fine. The “bullet” is instantiating because “Bullet(Clone)” shows up in the Hierarchy. I also tried it with a standard cube mesh and that shows up just fine.

Script attached to bullet:


	float speed = 10.0f;

	void Update()
	{
		transform.position += transform.forward * speed * Time.deltaTime;
		Destroy (this.gameObject, 20.0f); // destroy after 20 seconds just in case
	}

Sprite Components:

  • 2D BoxCollider
  • Sprite Renderer (order in layer: 10)
  • Script

In short, the sprite is not rendering when instantiated.

Any assistance would be greatly appreciated!
Thanks

EDIT 3/29/2014:
Upon further examination of this issue, Thanks again Key_Less, I noticed that the projectile is “flying off” at some weird angle when I paused the game the Bullet’s position was X: -6000 Y: -1100 Z: 0 and rotatation x: 0 y: 270 Z: 0. I’m certain the Quaternion is not “working correctly”, can anyone provide any insight into why this is?

The issue was that the sprite was being rotated 270 degree on the Y axis. I am posting this answer so that if anyone comes across a similar problem they can try ad troubleshoot the problem the same way
