I'm wondering if it's possible to store keyboard input history into a array and execute them at a later time? Basically I have a 3D grid game and a character moving around the grid. I want the user to enter all the movement instructions via right down left up keys while the player remains still, and once I press enter the player will begin to execute each instruction that is stored into the array.
any suggestions?
I would recommend using a List<T>
Example:
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class Training : MonoBehaviour {
public List<KeyCode> previousActions;
void Update(){
if(Input.GetKeyDown(KeyCode.A)){
Debug.Log("Do something");
previousActions.Add(KeyCode.A);
}else if(Input.GetKeyDown(KeyCode.S)){
Debug.Log("Do something else");
previousActions.Add(KeyCode.S);
//---Check the list--//
}else if(Input.GetKeyDown(KeyCode.D)){
Debug.Log("Check the list");
for(int i = 0;i < previousActions.Count;i++){
Debug.Log(previousActions[i]);
}
}
}

I'm making a store for my game and I'm making a system where the score I get in the game is saved and every time you play it adds and saves too, but this last part isn't working I don't know why, I'm taking a variable from another script called score it receives the value I got and had to add it to the previous value but it doesn't happen.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class CoinsManager : MonoBehaviour
{
public GameObject YellowSquare;
private int totalScore;
void Start()
{
YellowSquare.GetComponent<Text>().text = GameController.score.ToString();
totalScore = PlayerPrefs.GetInt("lastScore", GameController.score);
}
void Update()
{
SaveMoney();
}
void SaveMoney()
{
totalScore = GameController.score++;
PlayerPrefs.SetInt("lastScore", totalScore);
}
}
Why is the GameController.score completely detached from this? I would expect you rather do
// actually load the previous score into GameController.score
GameController.score = PlayerPrefs.GetInt("lastScore", GameController.score);
// then AFTER this update the text
YellowSquare.GetComponent<Text>().text = GameController.score.ToString();
.. and then in Update rather do
// Btw do you really want your score to be a counter of how many FRAMES you have played? o.O
GameController.score++;
PlayerPrefs.SetInt("lastScore", GameController.score);
// also update the text after changing the value
YellowSquare.GetComponent<Text>().text = GameController.score.ToString();
Since the keypad don't have buttons I added cubes to each number and attached a script to each cube so when clicking on a cube it will show it's number in the top area.
For example Key 1 (Cube) when I click on it when the game is running it's not firing the click on all the cube area same for all the other cubes :
When I click on the cube of key 1 it's working only on the left bottom area mostly on that sides. Even if the cube is covering the whole key area.
This is how it looks like when I uncheck the cubes mesh renderer :
Then when running the game and clicking on a cube : it's showing the number in the Security Keypad Text(Text Mesh)
This is the script attached to each cube :
using System.Collections;
using System.Collections.Generic;
using System.Text.RegularExpressions;
using UnityEngine;
public class SecurityKeypadKeys : MonoBehaviour
{
public TextMesh text;
private void Start()
{
text = GameObject.Find("Security Keypad Text").GetComponent<TextMesh>();
}
private void OnMouseDown()
{
string[] digits = Regex.Split(transform.name, #"\D+");
foreach (string value in digits)
{
int number;
if (int.TryParse(value, out number))
{
text.text = value;
}
}
}
}
The main problem is that on most of the cubes you need to click on specific point/small area to make it work and I want it to be working trigger when you click on each cube at any place on the cube.
Try the RaycastExample by robertbu code here and put it on a script. OnMouseDown() requires nothing else be in the way. That code will tell you if something is in the way. Also, try moving everything closer as OnMouseDown() has a depth limit to its raycast.
I recreated your above example, and it works perfectly, so something else must be wrong.
I am trying to create a game in Unity 2d. I have finished most of what I want to do and have moved on to the enemies. The enemies (dragons) come in from different points of screen. To do this I have placed sprite game objects where I want the dragon to spawn. I have made all of these objects a child of another object called DragonAncores. I attached a script to DragonAncores which says this...
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class DragonTracker : MonoBehaviour {
// is gold dragon in play?
public bool GoldDragonInit = false;
// curently active dragons
public int DragonCount = 0;
// defalts to 5
public int Difficulty = 5;
}
I am then attaching a script to each sprite which will eventually summon in a dragon Prefab (containing 2 colliders and an animator) biased of If statment logic derived from the other variables.
Below is the code I am using.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Dragons : MonoBehaviour {
// same as GoldDragonInit
bool GoldDragonSpawn = false;
// same number as DragonCount in DragonTrackeer
int LiveDragons;
// same as Difficulty
int DifLev;
//get cariables from other script
DragonAncors.cs.GetComponent.<DragonTracker>() GoldDragonInit = GoldDragonSpawn;
System.Random RNG= new System.Random();
void update()
{
RSpawn=RNG.Next(0,2)
DragonType=RNG.Next(0,101)
if (RSpawn = 1) ;
{
if (LiveDragons > DifLev) ;
{
if (DragonType > 99) ;
{
// summon regular dragon
}
if (DragonType = 100) ;
{
if (GoldDragonSpawn = true) ;
{
// summon gold dragon
}
}
}
}
}
}
This is throwing up this error list.
This shows my hierarchy in unity and the anchor points (the Squair crosshair looking things)
I have looked for other threads that adress this topic and they all try different methods, none work.
I am using Unity 2018.2.18f1
There are a few errors in your code here. The following is incorrect.
//get cariables from other script
DragonAncors.cs.GetComponent.<DragonTracker>() GoldDragonInit = GoldDragonSpawn;
The correct way to access this, seeing as you said DragonAncors is the parent would be:
GetComponentInParent<DragonTracker>().GoldDragonInit = GoldDragonSpawn;
This sets the GoldDragonInit Boolean to the value of GoldDragonSpawn. This has to be inside a function, as you have it outside of a function I presume you needed this set on start. Therefore I have placed it in the void Start() function. This is called at the start of the game(loaded scene).
You also do not need semi-colons ; after an if statement, however it does need to appear after every line of difinitive code. The code you have provided should instead look like this.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Dragons : MonoBehaviour {
// same as GoldDragonInit
bool GoldDragonSpawn = false;
// same number as DragonCount in DragonTrackeer
int LiveDragons;
// same as Difficulty
int DifLev;
void Start()
{
// variables from other script
GetComponentInParent<DragonTracker>().GoldDragonInit = GoldDragonSpawn;
}
System.Random RNG= new System.Random();
void update()
{
RSpawn=RNG.Next(0,2);
DragonType=RNG.Next(0,101);
if (RSpawn = 1)
{
if (LiveDragons > DifLev)
{
if (DragonType > 99)
{
// summon regular dragon
}
if (DragonType = 100)
{
if (GoldDragonSpawn = true)
{
// summon gold dragon
}
}
}
}
}
}
This works because DragonTracker is a script in the objects parent. If this was not the case then GetComponentInParent().GoldDragonInit = GoldDragonSpawn; would be replaced like so:
[SerializeField]
private GameObject DragonAncors;
void Start()
{
DragonAncors.GetComponent<DragonTracker>().GoldDragonInit = GoldDragonSpawn;
}
This is not valid c# code:
//get cariables from other script
DragonAncors.cs.GetComponent.<DragonTracker>() GoldDragonInit = GoldDragonSpawn;
Why? Because it isn't inside a method.
Also, the comment is wrong. It isn't getting a variable (typo, too), its setting a variable in another script!
The reason for the first...16 problems Visual Studio is complaining about are because of this line.
At this location you are only allowed to declare methods, fields, and properties and you're currently trying to access another class and change one of its members (something you can only do inside a method).
Additionally, you have .cs which I assume is because "DragonAnchors.cs is the file name!" which you don't need to do. I'm not sure how to go about rewriting this line (inside Start()) as I'm not sure what you're trying to actually do. That is, I don't know where an instance of DragonAnchors actually resides. You're calling GetComponent(), which is typically reserved for accessing components attached to game objects, but as you've attempted to do so on a static class reference, I'm not sure if you meant to call it on this or on something else.
This is how you can get to DragonTracker:
DragonTracker dt = GameObject.Find("DragonAncores").GetComponent<DragonTracker>()
Debug.Log(dt.DragonCount);
There are a lot of errors there and they may take some steps to go through, but first things first you should clear up the issue with the code you're trying to use being unsupported. Go into the project settings and change the compiler language version as it notes on the 5th error down. This should allow you to use the newer functionality.
I am an LSPDFR developer and I am building a callout. I am trying to get my spawn point to spawn at a certain coordinate.
I currently have:
SpawnPoint = World.GetNextPositionOnStreet(new Vector3(-2051.99463, 3237.05835, 1456.97021));
This is in C#. I get the error Argument 1: cannot convert from 'double' to 'float'. Does anyone know what to do? And I am also writing this in Visual Studio
I have tried removing:
private Vector3 SpawnPoint;
You need to add 'J' to the end of each coordinate.
This is a very old topic, but there are no answer ..
I searched for LSPDFR -An addon for GTAV. I had hoped for a lot of activity
There was not..
Anywitch
Someone may browse for this so i will add the way to do this in LSPDFR
Firstly To get a point inside the game-world:
Press F4
In console write:
PrintInfo
Press Enter
Now you have 3 values that represent a 3Dvector
Z is UP!
Lets say we got
x:111, y:222 z:10
Script:
In your variables define a spawnpoint
public Vector3 SpawnPoint;
You can now say
SpawnPoint = new Vector3(111.0f, 222.0f, 10.0f);
and use that as a position for a object.
You can also use an object, Ped, or your player, and set a spawnpoint close by:
SpawnPoint = World.GetNextPositionOnStreet(
Game.LocalPlayer.Character.Position.Around(300f));
That will make a spawn around 300 world meters from current pos your player is in.
So that is two different ways to make a spawn-position in LSPDFR.

I have an array InputFields, in my situation - six InputFields. How can I get the text and save it from each InputField?
Everything should work like this: I turn on the app, I change one, two or all of the input field, then turn off the application. Again, I turn on, and input fields have to be values which I wrote earlier.
I have a code that must seem to work properly, but this code works like this: it takes only the last value entered by the user and writes it to the last input field.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class SaveText : MonoBehaviour {
public GameObject[] InputFields;
public static string n;
public void Start ()
{
for(int i = 0; i < InputFields.Length; i++)
{
InputFields[i].GetComponent<InputField> ().text = PlayerPrefs.GetString (InputFields[i].name);
Debug.Log (PlayerPrefs.GetString (InputFields[i].name));
n = InputFields[i].name;
var input = InputFields[i].GetComponent<InputField> ();
var se = new InputField.SubmitEvent ();
se.AddListener (SubmitName);
input.onEndEdit = se;
}
}
public void SubmitName(string arg)
{
PlayerPrefs.SetString (n, arg);
}
An array of input fields I initialize dragging in Unity each input field in free cell in Script Component.
Well, you are using a single variable for all the different player prefs variables, n. So when you change a field (with SubmitName) it uses that n pref variable and changes it. This will correspond to the last value you gave to n in your loop.
An option would be to have that be an array too (private string prefValues[]) or to pass the calling input field to SubmitName (or rather it's name) and use that instead of n.
A little example (from your code you can actually change your GameObject[] to InputField[] which saves some GetComponent calls):
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class EventTest : MonoBehaviour
{
public InputField[] inputFields;
void Start ()
{
foreach(InputField field in inputFields)
{
var se = new InputField.SubmitEvent();
se.AddListener(delegate {
SubmitText(field.name, field.text);
});
field.onEndEdit = se;
}
}
public void SubmitText(string prefKey, string prefVal)
{
Debug.Log("Saved " + prefVal + " to " + prefKey);
}
}
Edit:
Added lines for saving/loading from prefs in the code below. For my test setup I just have two scenes. Both have two input fields and a button that calls that scene change. I can type stuff on the fields as I like, change scenes and it stays. Also upon restarting playmode in the editor.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
public class EventTest : MonoBehaviour
{
public InputField[] inputFields;
void Start ()
{
foreach(InputField field in inputFields)
{
// Get field values from player prefs if existing
// (it should only not exist the very first time or if you delete/clear the prefs)
if(PlayerPrefs.HasKey(field.name))
field.text = PlayerPrefs.GetString(field.name);
var se = new InputField.SubmitEvent();
se.AddListener(delegate {
SubmitText(field.name, field.text);
});
field.onEndEdit = se;
}
}
public void SubmitText(string prefKey, string prefValue)
{
// store the typed text of the respective input field
PlayerPrefs.SetString(prefKey, prefValue);
}
public void ChangeScene()
{
if(SceneManager.GetActiveScene().name == "Scene1")
{
SceneManager.LoadScene("Scene2");
}
else
{
SceneManager.LoadScene("Scene1");
}
}
}
If you want to save the data, after the application stopped or if it gets paused, you need to add some more functions to your MonoBehavior so that it can handle additional actions on a system end or pause.
Look at following functions in the documentation
OnApplicationQuit()
OnApplicationPause()
These functions will be called automatically. Inside these functions you need to iterate through the textfields and save them. It is one of the last functions that will be called before the program will lose it's recourses.
Regarding the Scene change, you would need the new scene to tell the old one to do any further actions. Like you can read in this post, there is only a way to know if a new scene was loaded.
Maybe you have a place where you can save the last active scene object and then call the last scenes function to do the saving process while the object is not cleared.
