Canvas bugged.

[InoXtiC]

This happens like few days ago making my Canvas unable to be showed pretty much bugged.
I managed to fix most of it but my inventory had an issue.

How do i fix that?

Also there’s issue with the cabbage being unable to pickup. Its not rendered on the player head, nor registered in the inventory after picking up the invisible cabbage, however the cabbage on the farmable area disappear.

Okay it seems that i managed to fix the issue, now its the second bug where the cabbage thing.. hmm

Hi Sync, are there any errors that appear on your Console when you harvest the cabbage?

You can also have a look at Part 17 of the series, where a couple of bugs are addressed in the first part: https://blog.terresquall.com/2022/12/creating-farming-rpg-in-unity-part-17/

It could be either a UI issue or the Item not registering.

When you pick up the cabbage in the scene, check InventoryManager in the Inspector under the ItemSlots array. Do you see the Cabbage ItemData in any of the slots? If yes, the issue is somewhere with the rendering of the UI.

If not, check the Cabbage prefab. Do you have the Cabbage ItemData assigned?

Okay i checked, it seems that when i harvest the cabbage it just disappear. Its not added to the UIManager either. If i have 5 at cabbage in the inventory, it should hold one on the hand when i harvest, 1 cabbage would be on Item Hand Slot and i middle mouse button it will keep to inventory adding the 5 cabbage i have to 6, but it seems that its not adding up. Weird.

Can you take a screenshot of what InventoryManager looks like in the Inspector?

I uploaded a post, not sure if its uploaded or not.

Hi Sync,

Can you upload your images onto Imgur instead? https://imgur.com/upload

The forum blocks links if you put too many of them together in a post, as that makes the post looks like spam.

Something is not set.

You can double click the error to get to the line where the NullReferenceExceptions are occurring, and see which variable isn’t set, and then trace it from there.

For instance, it looks like in the case of the InventoryManager, itemSlotor inventoryArray is unset in the StackItemToInventory function.

In the case of the Characters, check if characterData is set.

There are many issue i encounter so far such as, going from farming to home would have error

Hi InoXtic,

Sorry that the forum is flagging your message as spam. I’m looking into it. In the meantime, you will need to avoid posting too many links on your post, as it will cause our anti-spam software to falsely flag it as spam.

NullReferenceException error

For the NullReferenceException, look at line 52 of your InteractableCharacter script. These exceptions are usually caused when you try to access a property that is not there. For example, the rb.velocity line below will cause a NullReferenceException if GetComponent<Rigidbody>() fails to find a component:

Rigidbody rb = GetComponent();
rb.velocity = new Vector3(5,5,5);

This is because rb will be null if the first line fails. Hence, the code resolves to null.velocity. Below is a video explaining more about NullReferenceException errors:

Entering town error

For the error when entering town from home, you can double click on the error to show the line of code that is causing the error. Then just do a check to make sure that variable is not null. Something like this:

public void OnLocationLoad(Scene scene, LoadSceneMode mode)
{
        //The location the player is coming from when the scene loads
        Location oldLocation = currentLocation;

        //Get the new location by converting the string of our current scene into a Location enum value
        Location newLocation = (Location) Enum.Parse(typeof(Location), scene.name);

        //If the player is not coming from any new place, stop executing the function
        if (currentLocation == newLocation) return; 

        //Find the start point
        Transform startPoint = LocationManager.Instance.GetPlayerStartingPosition(oldLocation);

        if (playerPoint == null) return;
        //Disable the player's CharacterController component
        CharacterController playerCharacter = playerPoint.GetComponent();
        playerCharacter.enabled = false; 

        //Change the player's position to the start point
        playerPoint.position = startPoint.position;
        playerPoint.rotation = startPoint.rotation;

        //Re-enable player character controller so he can move
        playerCharacter.enabled = true;

        //Save the current location that we just switched to
        currentLocation = newLocation; 

}
