[Part 10] 2 Errors I’m confused about

[Luke]

(1) So, for the first issue, whenever I collect XP gems, only the first collect of the type is collected. This is really confusing because before part 11, it worked perfectly.

(2) This error happens during the upgrade screen, but it appears that the onclick event is deleted before it can be used and I don’t know why. The code is the exact same(I think) and I can’t find console errors.

Help would be appreciated!

(if the answer is in part 11 I will eat my hat.)

Hi Luke, I’m taking over the project from Xavier, so bear with me if I’m not very well-informed about some parts of the codebase.

For (1), is the collision detection done using OnTriggerEnter2D()? If it is, you can do put something like Debug.Log(name + " pick up triggered") on the function to see if the function fires for the pickups that are not working. The line prints the name of the object as well, so you can tell which object is being triggered. If certain pickups are not triggering, pause the game during play and check if they have a) a collider and b) a Rigidbody2D. Those 2 are needed for collisions to register.

For (2), will you be able to clip a video of this happening with something like ScreenToGif and post it on Imgur? Then you can embed it here.

I’ve tested out the Debug.Log solution and I think the reason is because it is destroyed before it hits the player. Still not solved.(I could be wrong on this.)

(btw u can use print() instead of debug.log)

[Terence]

Is there any script that is calling Destroy() on your GameObject? That is the only thing I can think of that is destroying your object before it hits the player.

The error might be in onTriggerEnter2D for this code:

void OnTriggerEnter2D(Collider2D col)
    {
        if (col.gameObject.TryGetComponent(out ICollectible collectible))
        {
            Rigidbody2D rb = col.gameObject.GetComponent<Rigidbody2D>();
            //rb.velocity = Vector2.zero;
            //rb.angularVelocity = 0;
            collectible.MoveToPlayer();
            collectible.Collect();
        }
    }

Also I’ve recorded the other error, but I don’t know how to embed.

    }

Also I’ve recorded the other error here.

I solved the issue where you could dodge pickups using the movetoplayer function above, complicated.
if that causes an error welp that’s it.

Nvm, the second error was because I decided to put removeUpgradeoptions after applyupgradeoptions. Fixed!

Hi Luke, glad you managed to fix the issues!
