How to save a list of items in Unity? - c#

I don't know how to save a List<T> of items I have and the inventory script and the database items script. I want to save the items that I have in my inventory but I don't know how. I try to create a class and make an Update() function but id doesn't work. It gives me an error
inventory<item> can't be deserialized
Can you help me please how should I save the items?
Here is the script o the player data that contains the save/load functions.

It looks like you are missing the Serializeable attribute.
Add it to your Item class like so ->
[Serializable]
public class Item {
///Your code here
}

Random Bug in Unity2D

I've been working on a project for the GMTK 2022 Game Jam recently, and I ran into a very strange problem. I have a dash that starts when you are moving and press space. It moves you in the direction of your velocity, then for a short time lets you move very quickly. It works perfectly fine in all cases, unless the direction you are moving is up and to the left, in which case, the if statement strangely won't trigger. I'm sure this is something idiotic, but I've been troubleshooting it for the last hour and it's been driving me insane.

How are your inputs setup? I am suspecting you have one key bound to multiple actions, like one key is set up as primary for an action and alternate for another action.
Personally I'd also stop using the assignment operators and increment instead. Instead of
playerInputh = 0;
if (Input.GetKey("right"))
{
playerInputh = 1;
}
if (Input.GetKey("left"))
{
playerInputh = -1;
}
if (Input.GetKey("right") && Input.GetKey("left"))
{
playerInputh = 0;
}
you can do
playerInputv = 0;
if (Input.GetKey("right"))
{
playerInputh += 1;
}
if (Input.GetKey("left"))
{
playerInputh += -1;
}
Net result is the same here - if you push both keys the result sums to zero, but the code is easier to read (IMO).
When you check things for key bindings also check alternates for space, because that's another one of the triggers you need to dash.

Unity script crashes editor

Here is my code:
void Update()

if (shipController.Mode == ShipController.ShipMode.Build)
{
var mouseInWorld = Camera.main.ScreenToWorldPoint(Mouse.current.position.ReadValue());
Debug.Log(mouseInWorld);

var oldPos = currentPos;

var iter = 0;
while (!shotPastTargetOrExact)
{
iter++;

oldPos = currentPos;
oldPosToTarget = posToTarget;
if (posToTarget == Vector2.zero) shotPastTargetOrExact = true;

{
if (posToTarget.x > 0) currentPos = new Vector2(currentPos.x += blockdistance, currentPos.y);
else currentPos = new Vector2(currentPos.x -= blockdistance, currentPos.y);
}
else
{
if (posToTarget.y > 0) currentPos = new Vector2(currentPos.x, currentPos.y += blockdistance);

currentPlacementBlock.transform.rotation = shipController.transform.rotation;
}
else if (currentPlacementBlock != null)
{
Destroy(currentPlacementBlock);
currentPlacementBlock = null;
}
}
}
It crashes when I try to stop the game with the play button in the editor. It has also crashed when starting build mode (see shipController.Mode)
The script works as intended but crashes when stopping the game.
I loged the iterations to try and see if it was looping forever but it doesnt seem to be that as it always comes out with a small iter number in the console
I fixed it by checking if the mouse was in the window before going ahead and performing the rest of the update
bool IsMouseOverGameWindow { get { var mousePosition = Mouse.current.position.ReadValue(); return !(0 > mousePosition.x || 0 > mousePosition.y || Screen.width < mousePosition.x || Screen.height < mousePosition.y); } }

How to prevent drag and drop if the node is not null [C#]

I have a problem with drag and drop on game. I want to block user if he is dragging the object from down to up in case they have sticks in same angles. if they dont so it is ok. But if they have even one stick in same direction so stick should go back to down to first position.
I am lost a bit. Can you help please :)
here is the code where I drag and drop also rotation...
Here on the pic generated stick group can fit only 1. and 3. places.

Function in Unity3d(c#) doesnt work correctly

I try to creacte some buildings in 2d, but it should not be touched with the other buildings.I have a
private GameObject building;
From Update i called function
buildFence(Vector2 nextPos)
where i create new building
And from this function i called function which must return boolean type
public bool canbuild()
{
//Debug.Log(building);
if (building.GetComponent<Rigidbody2D>().IsTouchingLayers(LayerMask.GetMask("Buildings")))
{
building.GetComponent<SpriteRenderer>().color = Color.red;
//Debug.Log("canb=false");
return false;
}
else {
building.GetComponent<SpriteRenderer>().color = Color.green;
return true;
}
}
but this function always return true. If i called the same function from Update,
everything works well.
All code here

Removing the barrier after the collision? [closed]

Closed. This question needs to be more focused. It is not currently accepting answers.
Want to improve this question? Update the question so it focuses on one problem only by editing this post.
Closed 8 years ago.
Improve this question
I'm making a game (Breakout) and I have a question,
The question is how can I remove the barriers after they get hit by the ball?
Of course, the ball must be able to go through the track after that (like Breakout game in general)
the next question is that can I make the barriers in run time mode?
Thanks

You need to learn use lists and proper use of classes.
For example :
public class GameObject{
public GameObject(int x, int y, int width, int height){
this.X = x;
this.Y = y;
this.Width = width;
this.Height = height;
}
int X;
int Y;
int Width;
int Height;
public bool DetectCollision(bool Ball){
//code to detect collision
}
}
Then in your main class, you can do thing like that.
List<GameObject> gameObjects = new List<GameObject>();
gameObjects.add(new GameObject(10,10,50,50));
gameObjects.add(new GameObject(20,10,20,50));
gameObjects.add(new GameObject(30,10,50,70));
gameObjects.add(new GameObject(40,10,90,50));
And to detect the collisions :
foreach (GameObject gameObject in gameObjects){
if (gameObject.DetectCollision(ball)){
//do something
}
}
