ok hi im so sorry for the delay, i got a little busy elsewhere
it states shelter tag is not there but ive provided them
the code it redirected me to is this one
i took GPT's help for this one
someone please help me out w this simulation part T-T

I recommend starting simple and learn the basics of debugging. For example, reading the errors and their callstacks and understanding what the cause is.

The errors are related to "Tag not found" but I have assigned the tag

The errors themselves point to a missing/unassigned reference. But there's not much we can help you with without seeing the errors callstack.

what shall i provide you with then?/

As I said several times already - the error/s callstack.
Click an error in the console - you will see more details in the section at the bottom. These are very important for understanding the errors. Copy the whole thing here.

Oh sorry, i thought i provided the error callstack. I'm sending it.

ok for starters, there is no movement in the game/scene view, after i press play

Should there be any? Do you actually have any code that should be moving stuff?
And then, I'd also check the console for errors and warnings. I can see some warning that could totally be related.
