Auto detect room transition, and auto-working minimap?

[JamesMWestbrook]

Trying to mimic the sample project's examples.
From what I understand at this point it should auto detect when you hit the edge of the screen, but it isn't doing that. The camera is properly constrained to the cell size.
I successfully got the minimap to show which cell you're in, except it's showing a bunch of X's.
Could I have some help figuring this out?
If you're willing to look through it, I included my source code. The main scenes to look at are game, TestScene, and Scene2. The script GameManager is on autoload.

I believe I'm doing it correctly? I have the correct scenes assigned in the map view, but when I walk out the room's exit and visit_cell gets called, it acts like I'm supposed to be entering the same room?

Did you read https://github.com/KoBeWi/Metroidvania-System/wiki/Quick-Start?
You need to add RoomTransitions module, or manually detect room change via room_changed signal.

[JamesMWestbrook]

I did but it's easy to miss details. I also followed the sample project's and the RoomTransitions module's examples and per my last comment, it looks like the signal isn't even getting triggered bc it acts like I'm in the same room as I'm leaving it.

You did not set in_game_cell_size property, and also your room tiles are shifted (not starting in (0, 0)). Although I'm still getting wrong player position, I'll try to investigate more and let you know.

[JamesMWestbrook]

Thank you. I'll keep trying to see what i can find.
When you ay it's not starting at 0,0, do you mean the tiles aren't drawn there or that it's transform position is shifted? As far as I can see it's all at 0.0, but i didnt' start drawing tiles from the most left edge until after you pointed it out.

I think I got it working when I switched it to global_position when tracking player position in _physics_tick, but now im encountering other errors I need to resolve that are my own fault. I'll update you when I get my end working, I feel like this should resolve it once I do that.

Looking at this again while the oven preheats and yeah the spawnpoint node2d node that the players spawn from isn't at 0,0 so if the position is off and I'm not using global_position that would be why I think. Will still get back when I resolve the other issues my own code started(the fact players despawn upon leaving the scene bc they are childs of the scene)

[JamesMWestbrook]

I got the next room to load after I fixed up my code, so the issue was me using a local position rather than global. Main issue now is the player seems to spawn off screen when the room changes. (And the minimap is still displaying weird)
The scene we transition into is Scene2. 90% of the logic should be in game_manager bc I decided to centralize the logic.
It looks like _on_room_changed should be where the player's position gets set, so I added a line of code for that based off the sample.
players[0].position = MetSys.get_current_room_instance().get_room_position_offset(prev_room_instance)
But nothing seems to have changed. I'm going to keep messing with this and looking at the sample and documentation you have, but so far I'm stumped with this again.
Edit: That one line I tried with global_position and position, right now it doesn't matter which it is bc I spawn the players with no node2D as parent, so position tracking should be accurate based on the fact it transitions rooms now.

You need to subtract the offset, not assign it.

btw you can enable display_player_location in Minimap node to show player location.

[JamesMWestbrook]

subtracting it did it, thank you!
Also to clarify about the minimap, my issue isn't I'm wanting it to show the player's exact location, it's that it shows a bunch of X's.

That's empty cell. You can remove the texture from MapTheme if you don't want it.
