Saving array data?
Update
I am updating the particle effect.. in the last part here:
pars[i].minSize = minsize[i] * scale; pars[i].maxSize = maxsize[i] * scale;
pars[i].worldVelocity = worldvelocity[i] * scale;
pars[i].localVelocity = localvelocity[i] * scale;
pars[i].rndVelocity = rndvelocity[i] * scale;
pars[i].transform.localScale = scaleBackUp[i] * scale;
}
that should be updating it.. sorry if that is not what you meant.
could you not just open unity and try out the script?
sorry if I'm being ignorant but I have only been using unity for about half a year.
Hello,
I am making a script that scales particleFX similar to transform scale so if you change scale to 2 then its twice as big....
I its working prefect except one problem.
Once I enter play mode or delete the particle prefab from the scene and then drag a new one into the hierarchy the data for the scale is lost.
along with this code I have a editor script that calls the UpdateScale function when a button is pressed.
var pars : ParticleEmitter[]; var scale : float; @SerializeField private var minsize : Array = []; @SerializeField private var maxsize : Array = []; @SerializeField private var worldvelocity : Array = []; @SerializeField private var localvelocity : Array = []; @SerializeField private var rndvelocity : Array = []; @SerializeField
private var scaleBackUp : Array = [];
function UpdateScale () {
for(i=0;i<pars.length;i++){ minsize.Add(pars[i].minSize); maxsize.Add(pars[i].maxSize);
worldvelocity.Add(pars[i].worldVelocity);
localvelocity.Add(pars[i].localVelocity);
rndvelocity.Add(pars[i].rndVelocity);
scaleBackUp.Add(pars[i].transform.localScale);
pars[i].minSize = minsize[i] * scale;
pars[i].maxSize = maxsize[i] * scale;
pars[i].worldVelocity = worldvelocity[i] * scale;
pars[i].localVelocity = localvelocity[i] * scale;
pars[i].rndVelocity = rndvelocity[i] * scale;
pars[i].transform.localScale = scaleBackUp[i] * scale;
}
}
Editor script:
using UnityEngine;
using UnityEditor; [CustomEditor(typeof(Scale))] public class ScaleEditor : Editor { public override void OnInspectorGUI() { Scale scaleBeingInspected = target as Scale; base.OnInspectorGUI(); if (GUILayout.Button("Update Scale")) { scaleBeingInspected.UpdateScale(); } }
}
So I was wondering if there is anyway to make that scale data get saved....
Hopefully I worded this correctly. I am in a hurry to get this code ready.. so any help would be greatly appreciated!
- You need to serialize the private variables.
- You need to use built-in arrays or Lists.
- Private variables are not serialized (stored) by default.
Update
See this related question I just asked.
You need to explicitly tell unity the type of your array. You have to explicitly type the array with your target type. Simple. Use a built-in array or a List.
For example:
@SerializeField
private var minsize : float[];
Then you can allocate enough memory (since you can't use Add() any longer):
minsize = new float[pars.length];
Another update
You were allocating arrays in the loop. Also I cleaned up some of the code to make it a little more readable. Are you sure that you are updating the emitters somewhere along the way after you've edited them?
var pars : ParticleEmitter[]; var scale : float;
@SerializeField private var minsize : float[];
@SerializeField private var maxsize : float[];
@SerializeField private var worldvelocity : Vector3[];
@SerializeField private var localvelocity : Vector3[];
@SerializeField private var rndvelocity : Vector3[];
@SerializeField private var scaleBackUp : Vector3[];
function UpdateScale () {
var length = pars.length;
minsize = new float[length];
maxsize = new float[length];
worldvelocity = new Vector3[length];
localvelocity = new Vector3[length];
rndvelocity = new Vector3[length];
scaleBackUp = new Vector3[length];
for ( i = 0 ; i < length ; i++ ) {
var emitter = pars[i];
minsize[i] = emitter.minSize;
maxsize[i] = emitter.maxSize;
worldvelocity[i] = emitter.worldVelocity;
localvelocity[i] = emitter.localVelocity;
rndvelocity[i] = emitter.rndVelocity;
scaleBackUp[i] = emitter.transform.localScale;
emitter.minSize = minsize[i] * scale;
emitter.maxSize = maxsize[i] * scale;
emitter.worldVelocity = worldvelocity[i] * scale;
emitter.localVelocity = localvelocity[i] * scale;
emitter.rndVelocity = rndvelocity[i] * scale;
emitter.transform.localScale = scaleBackUp[i] * scale;
}
}
hello statement.
I tried what you said and no luck :(
I edited my question with the new code maybe you can look at it and tell me if i edited it right?
Looking at the documentation again it says "Arrays of a serializable type". I don't know if Array host a "serializable type". Can you change it so that the arrays are typed? Like if your $$anonymous$$size is storing floats can you do private var $$anonymous$$size : float[];
hmmmm I have tried that but then you cant accesses the Array.Add(); function :( and i need that function for the script to work... any ideas? thanks
See my update. You need to allocate the array with the 'new' keyword before using it.
Update:
ok I am using the exact same code you posted and here is a pic of the Hierarchy:
ok sorry for answering instead of commenting but that would be the last comment, so then you could not write back.
so still not working.. I might gave overlooked something..
thanks a lot for helping me this!
here is the updated code:
var pars : ParticleEmitter[]; var scale : float;
@SerializeField private var minsize : float[];
@SerializeField private var maxsize : float[];
@SerializeField private var worldvelocity : Vector3[];
@SerializeField private var localvelocity : Vector3[];
@SerializeField private var rndvelocity : Vector3[];
@SerializeField private var scaleBackUp : Vector3[];
function UpdateScale () {
for(i=0;i<pars.length;i++){
minsize = new float[pars.length];
minsize[i] = pars[i].minSize;
maxsize = new float[pars.length];
maxsize[i] = pars[i].maxSize;
worldvelocity = new Vector3[pars.length];
worldvelocity[i] = pars[i].worldVelocity;
localvelocity = new Vector3[pars.length];
localvelocity[i] = pars[i].localVelocity;
rndvelocity = new Vector3[pars.length];
rndvelocity[i] = pars[i].rndVelocity;
scaleBackUp = new Vector3[pars.length];
scaleBackUp[i] = pars[i].transform.localScale;
pars[i].minSize = minsize[i] * scale;
pars[i].maxSize = maxsize[i] * scale;
pars[i].worldVelocity = worldvelocity[i] * scale;
pars[i].localVelocity = localvelocity[i] * scale;
pars[i].rndVelocity = rndvelocity[i] * scale;
pars[i].transform.localScale = scaleBackUp[i] * scale;
}
}
Ins$$anonymous$$d of posting another reply, edit your question ins$$anonymous$$d.
... And I would write back. I get perfect messages from unityAnswers system that someone would reply to any of my posts :) So do not be afraid I notice you less if you post a comment in my answer.
yeah sorry. I have noticed that it only allows 8 comments and there are 7 now so if I had commented then how would you have written back?
thanks for the code cleanup I am kind of unorganized hehe
updated the question
anyway thanks for the code clean up and
ok that was weird it cut of what I was going to say...
I updated the question.
Huh? It still doesn't work for you? have you seen my update? I went ahead and tried it myself. I create a game object, add your Scale script, and add a particle emitter to it. I set scale to some value, say 2 and press update. I see the many arrays are populated. I make a prefab out of it. I delete it and add it back to the scene and all values are there, as expected. I think you're doing something way different than what I assume you were doing with this script unless you haven't tried the new version.
