ORK3 3D Grid Battle set up tutorial

You can use the 2D grid tutorial, and if you already have a project started can skip most the setup since you should already have that. The actual Grid related part is pretty much the same regardless of dimensions: https://orkframework.com/guide/tutorials/2d-grid-battle-rpg/start-2d-grid-battle-rpg/

The main difference between non-grid and grid start/end is that in the Start you want to actually display the grid, and then start allowing placement (or automatically placing) for the combatants.

I've gotten up through the end of the Battle AI part of the tutorial. Note that I'm not using the tutorial assets and haven't set up any of my menu system yet. When I go to playtest moving around on the grid in the battle, the grid-map loads, enemies are placed, and I go into player placement. The moment I select a hex for placement I get the following error in the consol and the game will not move forward in any way:

NullReferenceException: Object reference not set to an instance of an object

Anyone know what's going on and what I need to do?

Not yet. I'll get that set up next then! : )

haha. Fair enough. Alright. I've gone through all of the tutorials for setting up menus and set up menu systems for my whole game using the 3D RPG Quickstart tutorials. That problem is resolved, but I do have a new problem. It's likely this will be easily resolved by a tutorial and I just haven't figured out which one.

I get to the battle, I enter combatant placement, I place my first (and currently only) combatant from the player group in a valid cell, and then it pulls up a menu with nothing on it and there's no way forward. I'm guessing this is a combatant selection menu that hasn't been properly set up yet? Or maybe a menu to select the next combatant I'd like to place (from a list of no others available)? I thought that had been set up at some point, but I can't find where so probably not. Any suggestions on where to look for a basic combatant selection menu set up tutorial for a grid battle? Or what menu this is and what the right tutorial is to set it up properly so I can proceed into the battle?

I seem to have resolved that problem. The player combatant selection and grid placement are both successes. Initiative is rolled. And I get to the player's turn.

But I have a new problem: I can't seem to issue any movement commands. I've double checked the movement schematics, and they're set up the way they are in the tutorial. If I had to guess I'd guess that it's not detecting what cell I'm mousing over (although that is a little difficult to tell, as I I'm not using the cell prefabs from the tutorial and they aren't set up to color shift when selected yet.)

EDIT: I've also tried using arrow keys to select a cell and then hit the select command and nothing happened.

They have a "move range" of 5 under battle information, although it's not listed as a "grid move range" (the "grid" is not there, just "move range". If that matters.)

Looking at the battle information, it lists:
Can Choose - False
Is Choosing - True
Action Fired - False
Action State - Available
Waiting for Action - True
Auto Attacking - False
Current Action - -
Receive Actions per turn - False
Action Bar - 25
Used Action Bar - 0
Action time - 0.0/0.0
Move Range - 5

Are either of the bold indicative of a problem?

Currently the Battle Start Schematic basically matches the 2d Grid battle tutorial for it, minus the camera stuff. So it goes like:
Show Battle Grid > Store Music > Play Sound > Wait > Spawn Battle Combatants > Player Grid Placement > (unity console outputs depending on if player grid placement was successful or not.) > Change Music > Change Game State.

It does say the grid placement is successful in the console when I run the battle. Should I have it delete the existing player combatant objects and then respawn them as part of the battle start schematic? I remember that being a part of my ORK 2 setup.

Alright. I'll see what I can do about that.
