I'm making a mining game, where you have a rest area, and a mine area (all of this stuff works well) but when I "hire a new worker" the main miner clones, and is put in the starting area. When I clone the main miner, the cloned miner's size goes to 6k something something.
public void moreMiners(){
if (gm.Diamonds >= gm.mmcost){
gm.Diamonds -= gm.mmcost;
GameObject newplr = GameObject.Instantiate(plr);
newplr.gameObject.transform.localPosition = plr.transform.position;
}
}
duplicating code ^
help is appreciated
Make sure that "plr" reference is the original Prefab from your assets folder and not from your scene, then what you can do is to check your original prefab inside your assets folder and see if the scale is the one that you want to have.
Also when you Instantiate an object you can parse the position too as a parameter like this:
GameObject.Instantiate(plr,position);

I am trying to load an animation from an fbx file and have it play on a GameObject:
TestObject.AddComponent<Animation>();
animation_handler = TestObject.GetComponent<Animation>();
walking_anim = Resources.Load("fbx_anims/walking_anim_test", typeof(AnimationClip)) as AnimationClip;
if(walking_anim == null)
{
Debug.Log("walking anim not found");
}
walking_anim.legacy = true;
animation_handler.AddClip(walking_anim, "walking");
animation_handler.wrapMode = WrapMode.Loop;
In the game loop, I tried using this:
if (Input.GetKeyDown(KeyCode.W))
{
if (!(animation_handler.IsPlaying("walking")))
{
animation_handler.clip = walking_anim;
animation_handler.Play("walking");
}
}
It doesnt give any errors, yet it doesn't work either. Anything I'm missing?
EDIT: For clarification: The model stays in the default T-Pose, after pressing 'W'. After inserting Debug.Logs at different points, I can confirm that the Play function is getting called only once, after which IsPlaying always returns true. Yet the "playing" animation causes no visual changes in the model (yes, the bone names are the same).
You don't want to use the Animation component, it is an old legacy component that has been replaced by the much improved Animator component. There are a lot of good posts on the Internet on how to use it - no need to repeat it here. The important steps are:
Add the Animator (not Animation) component to the model.
Create an "Animator Controller" in your project and add the clips (like the "walking_anim"). Here you can have a lot of different clips and tell Unity how to interpolate between them by using different parameters.
Add the "Animator Controller" to your "Animator" component.
Add an "avatar" of your model (usually created when the model is imported).
By code alter the parameters of the Animator Controller to tell it which animation clips to play.
It may look like a lot of steps, but it is not so hard and you will quickly have a walking, running, jumping creature on your screen. Good luck!
I have created a code file in Unity and assigned it to an empty GameObject I have placed in the scene:
var obj = new GameObject("Sample");
obj.transform.position = new Vector3(0, 0, 0);
var text = obj.AddComponent<TextMesh>();
text.text = "Hello world";
When I run the scene, I can see the text. And that is my problem: I did not specify anywhere in code to add obj to the scene, but it gets placed automatically apparently.
This can be a problem if I want to introduce an object later than instantiation time.
What am I doing wrong? How can this be achieved? What are the patterns/best-practices here?
Immediate fix:
Use obj.SetActive(false) to temporarily disable the object and then use obj.SetActive(true) when you need the object to be active.
Other solutions / best practices:
Create the object you desire in the scene, save it as a prefab (prefabricated object) and then only instantiate it when you need it. Here's a link for further reading into the prefab system. https://docs.unity3d.com/Manual/Prefabs.html
Object pooling is typically used when you will have a bunch of the same objects (like lasers, bullets, etc). Watching this video may be of help: https://www.youtube.com/watch?v=tdSmKaJvCoA
Working in Godot 3.2, I have a scene, Player.tscn. Near the top of Player.tscn, I have "class_name Player"
Now, when instantiating the Player, I have, as far as I see it, two options:
player = Player.new()
or
player = load("res://Player.tscn").instance() as Player
Now, the first version seems best to me...but it clearly isn't. If I use .new(), it claims that it has no children, and any method calls that attempt to get to its children (.get_texture() on a Sprite, e.g.), produces things like "Attempt to call function 'get_texture' in base 'null instance' on a null instance", because apparently Player has a no children.
Of course, doing it the second way, everything works fine. But why? Why can't I just use .new() if I've registered it as a class using class_name?
I'm new to Godot myself so I may be wrong, but I think it's because the .new() keyword is a language feature for loading single classes/nodes,
whereas .instance() is more of an engine feature that takes a packaged scene which is a combination of many classes/nodes, and restores their relative position in the tree, attaches scripts and resources, etc
So if your player is a tscn scene, you'd do something like:
var player = load("res://etc/Player.tscn").instance()
get_tree().root.add_child(player)
player.global_transform = etc ...
which would load the root node of Player.tscn and all of its children (rigidbodies, collidershapes etc) into the scene tree, set their relative positions, connect the scripts and what have you
Or if your Player is a class or a GDScript, you could do
var player = Player.new()
get_tree().root.add_child(player)
player.global_transform = etc ...
Which would add the single-node root player object only into the scene tree, but not any children
Once it's in the scene tree and _ready()'s triggered though, you can instantiate and attach the child component nodes (.new() > parent.add_child() > set transform) from the script itself
Does anybody know how can I include scripts when my objects clone. In my game, I need to make that when my ball hit moving wall, then there is need to show new wall including my moving scripts. MY CASE: new wall is shown, but it is not moving.
Please help.
Kind regards
Well it is very easy.
First case: if you are using the prefab to instantiate, be sure to assign on the prefab your scripts.
Second case: if you are taking the template to instantiate directly from GameObject of wall, it should create the GameObject with exatly same scripts.
If it is still not moving, check in Inspector the cloned wall, if the scripts are enabled, and double check how the scripts work (maybe needs some initializing or whatever)
If your script is not on your prefab (for any reason), you can add via a script:
void CreateWall(){
GameObject obj = (GameObject)Instantiate(wallPrefab);
NewScript ns = obj.AddComponent<NewScript>();
}
The only advantage I could think about that way is that you can add specific components based on a specific situation. Say you want to add Script A if condition A or Script B if condition B:
void CreateWall(){
GameObject obj = (GameObject)Instantiate(wallPrefab);
switch(condition){
case A:
obj.AddComponent<ScriptA>();
break;
case B:
obj.AddComponent<ScriptB>();
break;
}
}
Is there a way to assign multiple assets to multiple variables on the inspector???
My case is this, I have 5 objects, those objects have a script wich have around 1200 variables used to play SFXs. When Unity compile the script I have to manually drag and drop the SFX from the assets to the variable on the inspector, or go to the inspector, scrol to the variable, click the dot and then select the SFX file from the window.
Is there a way to speed this up?
You should create a public List of Audio Sources which will appear in inspector. Lock the inspector by clicking look in right top.
Now select all the files from Project and drag on list. All files will be added to list. Now if you want a specific file you can find the file by its name for example:
AudioSource GetAudioSource(string SourceName)
{
return audioSourceList.Find(item => item.Name == SourceName);
}
Use the Resources.LoadAll method to access all the assets from the path parameter via scripting. Probably put that method call in Start. Might have to rename the files to pull the right order from the LoadAll method if they result in some alternate order.
EDIT: Here's some example code...
(NOTE: Loads from Resources/Sound/SFX folder)
For reference: http://docs.unity3d.com/ScriptReference/Resources.LoadAll.html
public class YourClassNameGoesHere : MonoBehaviour
{
Public AudioClip[] BA;
void Start ()
{
BA = (AudioClip[]) Resources.LoadAll("Sound/SFX");
}
}
I found a solution for this problem. I must say, it's not perfect, in fact, it should not be used unless is absolutely necessary.
To speed up the assign you could do this:
Create a variable
public AudioClip ma, me, mi, mo, mu;
At Start() add
ma = Resources.Load("Sound/SFX/MA") as AudioClip;
me = Resources.Load("Sound/SFX/ME") as AudioClip;
mi = Resources.Load("Sound/SFX/MI") as AudioClip;
mo = Resources.Load("Sound/SFX/MO") as AudioClip;
mu = Resources.Load("Sound/SFX/MU") as AudioClip;
After compile the public variables will be available on the Inspector as empty variables, but, on runtime the variables will be filled with the content of the folder Resources/Sound/SFX (Assets\Resources\Sound\SFX).
Why shouldn't be use unless necessary?, first, it's a bad practice; second, it's a cheap trick that comes at a price (on mobile devices it load all the resources so will consume RAM fast). In my test, all my sound clips take as much as 169 MB. On PC it's not much of a problem, but if your target is Mobile games, this is something to take into consideration. And third, on web player, ALL resources will be streamed first.
On a side note, this cheap trick ignores the way Unity handles assets. Unity force you to assign assets manually because if the asset is not use, it will not be integrated into the build. This trick force everything to be loaded and be integrated into the final build, used or no. On the other hand, if you are assign it, you will use it... right?
The answer and example given by #Jayson Ash lead me to the right direction.
