Problems with code

Hello All, I am making an upgraded version of the demo space shooter game, and I am having trouble with a certain line or two of code, the whole thing being attached.

My problem is, I am trying to put in power-ups, but when I collect them, it changes nothing. It should make the fire rate, as well as the actual shot, change. the fire rate should be increased, and the single bolts should become a multibolt (name of object) I created and tested.

Also, I am having trouble with the timeing of the powerup, not being able to figure out how to time it for 10 seconds.

The code is attached; thank you!

 

just to make a start:

your methods are named wrong.

it has to be void Start
and
void OnTriggerEnter(Collider _other)

otherwise they won't be called by the UnityEngine

 

Sorry, that might not be able to be opened. Here is the code:

using UnityEngine;
using System.Collections;

[System.Serializable]
public class boundary
{
public float xMin, xMax, zMin, zMax;
}
public class PlayerController : MonoBehaviour
{
public float speed;
public float tilt;
public boundary bounds;

public GameObject shot;
public bool poweredup;
public GameObject multishot;
public Transform ShotSpawn;
private float fireRate;
private float nextFire;
void start()
{
fireRate = .5f;
poweredup = false;
}
void Update()
{
if (Input.GetButton("Fire1") && Time.time > nextFire)
{
nextFire = Time.time + fireRate;
if(poweredup == true)
{
Instantiate(multishot, ShotSpawn.position, ShotSpawn.rotation);
}
Instantiate(shot, ShotSpawn.position, ShotSpawn.rotation);
}
}

void ontriggerenter (GameObject other)
{
if(other.tag == "powerup")
{
poweredup = true;
fireRate = .001f;
}
}

void FixedUpdate ()
{
float moveHorizontal = Input.GetAxis("Horizontal");
float moveVertical = Input.GetAxis("Vertical");

Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);
rigidbody.velocity = movement * speed;

rigidbody.position = new Vector3 (Mathf.Clamp(rigidbody.position.x, bounds.xMin, bounds.xMax), 0.0f, Mathf.Clamp(rigidbody.position.z, bounds.zMin, bounds.zMax));
rigidbody.rotation = Quaternion.Euler (rigidbody.velocity.x * tilt, 90.0f, 0.0f);
}
}

 

Two functions have lowercase, needed uppercase.

Change start() to Start() and ontriggerenter() to OnTriggerEnter (). Ontrigger returns a collider not a gameobject. write this OnTriggerEnter (Collider other)

 

I got those, what else?

 

You mean for your Powerups?

I have on my Office same that works. But im far away from my office came back in a few hours. Can show you a example.

For now i can give you a Tip. I make it with a Coroutine.

 

Is this game 2d? If so, why are you using 3D rigidbodies....

 

because I am using 3d models that bank when moving left and right, and torpedoes that tumble towards you.

 

Ahhh, okay. Well, the powerup system should be fairly easy to achieve if you use coroutines; that will allow you to set a WaitForSeconds(x) to control the duration of the powerup. I would use another coroutine with a specified WaitForSeconds to control the fire rate as well. I try to avoid putting things like that in the update function and often lean toward coroutines because you have much more control over them.

I could write this for you, but that would not teach you anything, and given that coroutines are such a big part of game development you really should familiarize yourself with them and their functionality. Here are some links to a few resources that will help you out with this. I hope this helps and best of luck to you! If you have any more questions please feel free to respond again to this thread or contact me personally at hamsterbytellc@gmail.com. Cheers!

 

Thank you, my friend. I will implement that in class.

And yes, I am in high school.

 

Good on ya. The earlier you start the more natural it feels when you have to learn new things! Again, if you need any more help you can get at me personally via my website or my Twitter account; links in my signature.
