"Using transform.position to move objects bypasses the physics simulation step." is my issue it seems. Although I used rb.addforce to move object on the path, i used sr.transform.localPosition to flip the beet so it faces the right directions. (The reasons why is because I could make only transform work)

#

Hmmm I commented all parts with transform and collision still does not happen

#

Ok, i tested the collision code on static object and its not working TT

honest sinew "Using transform.position to move objects bypasses the physics simulation step."...

This would only cause the collisions to not work "sometimes", so it's probably not the main issue in your case.

#

So you need to check the other things in the guide

honest sinew Jan 6, 2022, 11:49 AM

#

Hmmm

#

I checked everything else, maybe I need to set the rigidbody's Collision Detection mode to Continuous Dynamic

#

Since the Snowball is pretty fast??

#

Take screenshots of the relevant object's inspectors.

honest sinew Jan 6, 2022, 11:53 AM

#

I set Collision Detection
to Continuous and collision still does not happen

#

Ok

#

clever pier Jan 6, 2022, 11:59 AM

#

Ok, then take a screenshot/video of when the objects supposed to collider with gizmos visible.

honest sinew Jan 6, 2022, 11:59 AM

#

ok

clever pier Jan 6, 2022, 12:00 PM

#

Gizmos of both objects including the colliders outline. You might need to select them in the hierarchy for the gizmos to be visible

#

I have a Deactivate method in snowball animation (attached to last frame of explosion animation), could it be the cause?

#

How do you know when to explode it?

#

how do you trigger that animation?

#

And yes, that might be a problem

#

comment out that line and see if you have a collision

honest sinew Jan 6, 2022, 12:18 PM

#

ok im goint to comment it out

#

Ok weird thing happend

#

I commented out deactivate and animation staerted looking weird, triggerin explosion on mouse click, but then, i put deactivate in back as it was and....... collision works now?????

#

what

#

I did not change script what happened ?????????

clever pier Jan 6, 2022, 12:25 PM

#

🤷‍♂️

#

But it works now, right?

honest sinew Jan 6, 2022, 12:28 PM

#

Ok, nope it broke again. Now when i played it again to record it, beet disappears before colliding with snowball

clever pier Jan 6, 2022, 12:28 PM

#

beet?

honest sinew Jan 6, 2022, 12:30 PM

#

(That red monster thing)

#

Now for some reason beet location changes

#

???

#

Ok this is very weird, why the beet location just changes

#

In previous video you can see that monster is going left and right on its path, but now, for some reason the monster goes higher???

#

Im going to reload unity real quick somethings weird

clever pier Jan 6, 2022, 12:38 PM

#

No clue. You'll need to debug that.

honest sinew Jan 6, 2022, 12:38 PM

#

Ok, reloading fixed it

#

Now the monster randomly goes to that specific spot after some time

#

Maybe A* is glitching out ?? Same code as before but this stuff happens now

clever pier Jan 6, 2022, 12:49 PM

#

Possibly. Disable the ai and see if that happens.🤷‍♂️

honest sinew Jan 6, 2022, 12:51 PM

#

Yep, its the AI

#

btw, even with disabled deactivation on snowball, beet still does not detect collision it seems

#

Looks like something broke but it worked before, why it broke now??

clever pier Jan 6, 2022, 12:54 PM

#

honest sinew

Take screenshots like these again, but with collider components expanded.

clever pier Jan 6, 2022, 12:55 PM

#

honest sinew Looks like something broke but it worked before, why it broke now??

No clue. Depends on your pathfinding implementation.

collider components expanded?

clever pier Jan 6, 2022, 12:56 PM

#

I can't see their settings on your screenshots.

#

*photos.

#

They should really be screenshots btw

honest sinew Jan 6, 2022, 12:58 PM

#

I am using remote desktop, the screenshot with keyboard does not work, lets see, i will try to figure it out

#

Ok

clever pier Jan 6, 2022, 1:06 PM

#

You have 3 errors in the console.

honest sinew Jan 6, 2022, 1:09 PM

#

Now only one shows up

#

Now only this error pops up https://hastepaste.com/view/T3h1

I'm not sure if it's relevant or not(can't see the whole callstack in the error), but it might be related to your pathfinding.

honest sinew Jan 6, 2022, 1:13 PM

#

hmmm

honest sinew Jan 6, 2022, 1:14 PM

#

clever pier I'm not sure if it's relevant or not(can't see the whole callstack in the error)...

Ok maybe it's not relevant. Not sure.

honest sinew Jan 6, 2022, 1:16 PM

#

Seems a bit too advanced for me :, )

#

man, where do i even look for solutions for astar???

clever pier Jan 6, 2022, 1:30 PM

#

honest sinew man, where do i even look for solutions for astar???

On their website/github/community? Or try to debug on your own.

honest sinew Jan 6, 2022, 1:32 PM

#

ok, i will try. I wonder if collision detection is fixable

clever pier Jan 6, 2022, 1:34 PM

#

it is for sure. You just need to debug.

honest sinew Jan 6, 2022, 1:35 PM

#

Hmmm, I should try debugging collision detection code?

clever pier Jan 6, 2022, 1:40 PM

#

honest sinew Hmmm, I should try debugging collision detection code?

Yep. Debug whatever you think the cause of the issue is.

honest sinew Jan 6, 2022, 1:55 PM

#

hmm, I cant figure it out, with deactivate disabled explosion animation starts to play (collision does not happen). When the disable is enabled, collision does not happen either, im stumped.

honest sinew Jan 6, 2022, 2:24 PM

#

I fixed it! i threw away Collider collision! and just added some code in snowball ontriggerenter2d!

#

now the only issue i have is broken pathfinding...

honest sinew Jan 6, 2022, 3:16 PM

#

Cant find anything on pathfinding, the error is NullReferenceException: Object reference not set to an instance of an object.

clever pier Jan 6, 2022, 3:22 PM

#

If it's the same error as before, ignore it for now. It seemed to be related to editor loop.

#

focus on debugging the pathfinding

honest sinew Jan 6, 2022, 3:28 PM

#

tbh, I am so new to c# that probably just remaking everything will be easier for me. It worked before.. (T_T) I will try again tomorrow.
