Random generation
I want to create a tube spawning mechanic. I had something done, but for some reason it does not want to go in the direction I want it to go. It also does not go further then one object, it just spawns in one another.
Code: using UnityEngine; using System.Collections;
public class TubeCreation : MonoBehaviour {
public GameObject tubeObject = null;
public float add = 100000f;
void Update () {
Debug.Log("<color=blue>Info:</color> Object Created");
tubeObject = Instantiate (Resources.Load ("Prefabs/prefab_tube"), new Vector3(0,0,287),Quaternion.Euler(0,90,270)) as GameObject;
tubeObject.transform.Translate(Vector3.right * add * Time.deltaTime);
}
}
My ships model is backwards. So I use back to go forward, please keep that in mind.
You are trying to spawn a tube every frame from your ship?
I notice that you just use the same coordinates for all pieces. Notice that Time.deltaTime is "The time in seconds it took to complete the last frame (Read Only).". On a "strong" computer this will (probably) be about the same value. You don't use any varying variable, so it will only spawn in one place.
Thanks @Salmjak . But I don't really get it are you saying I need the default value and then add coordinates every time? How would I do this?(Also, it really lags do you have any fix for that to?)
Quite a few things to note:
Instantiation on each frame is quite expensive, performance-wise.
Instantiation with Resource.Load frequently is even worse.
Solution: You should be using the public GameObject variable in order to assign your prefab from the project folder. Also, you shouldn't instantiate per frame, in this case, this doesn't seem to make sense anyway, unless you need ~ 50-60 tubes to be spawned per second, which i doubt.
You've got a fixed value for the vector's z-value.
When you feel like multiplying Time.deltaTime with such a huge number, there's often something wrong (not always).
In order to simplify all that, use an integer or float variable which starts with the first z-value, or use a Vector3 in order to store x,y,z at once. Take another variable that defines your offset for each instantiation (float, int or Vector3, just as you like).
I fixed a few things and added a key input for the spawn control, play around with it and you'll get the idea. The current offset is 1 unit in x-direction for testing purposes with Unity's built-in cube.
Here's the code:
using UnityEngine;
public class NewBehaviourScript : MonoBehaviour
{
// drag the prefab from the project folder in the inspector slot
public GameObject tubeObject;
// current startPosition (I've chosen 0,0,0 here)
public Vector3 nextSpawnPosition = Vector3.zero;
// the offset 1,0,0
public Vector3 offset = Vector3.right;
void Update()
{
// only instantiate when space bar is pressed
if(Input.GetKeyDown(KeyCode.Space) && tubeObject != null)
{
Instantiate(tubeObject, nextSpawnPosition, Quaternion.Euler(0, 90, 270));
// add the value to the spawnPosition
nextSpawnPosition += offset;
}
}
}
@ThuverX If you don't want to press a button, only put
Instantiate(tubeObject, nextSpawnPosition, Quaternion.Euler(0, 90, 270));
into Update. But then again, you'll instantiate per frame and very, very often. I really doubt you want that.
@Suddoha Can I make it generate when I'm only in range? For less lag?
@ThuverX Yes, you actually can. There are methods like Vector3.Distance and others that you should take a look at. Unfortunately, i cannot write all the code for you.
