Hey everyone!
Hope you all had a great week. Feeling a bit funny this week, so not as much got done as I'd have liked, but onwards and upwards!
I've started on a new city area, so have been feeling out how it should look and the "rules" around it. It's a very different area from the stuff that I've made so far. Those have all been in various states of being very lived in, and I want to contrast that with having a very clean city, almost sterile. It's the home of Monomind, the big bad corporation, so I want it to feel oppressive and a bit bleak.
Here's some very work in progress shots. They're lacking most of decoration and wandering npcs.
I tried to show the pathway for the player using the blue highlights on the floor. Joe pointed out that I should take this further by also showing what is actually traversable. For example, in the shot above, I had originally used blue flooring under the center building, but now the pillars are ringed in blue to show that you can go underneath.
As mentioned above, I really wanted to have the city be very clean, but currently it's looking a bit too bland and not actually lived in, so this coming week I'll go back in and add some grime and dirt and a few bit's of foliage and things.
The big screen in the middle is a rendertexture with some UI projected on it. Eventually I'll add some nice sprites and animations for the UI elements and things, but for now I just wanted to check it would work as I was expecting.
I've also done a bunch of work on the custom tile mapper, fixing some stuff and adding a couple of new features to help with the workflow.
Firstly, I've been meaning to add flood fill for a long time. I just added a simple recusive thing to swap the sprite out for the clicked on tile, and then check the tiles north, south, east and west and if they match the original then swap their sprite too, then call the same thing on each of those. It doens't handle filling empty tiles yet, but I'll get to that soon
The next feature I wanted was to be able to ctrl+click on a tile and select the layer that tile is on. Pretty simple but it has sped up my workflow loads! I also discovered a much better way of selecting tiles using a built in unity function (HandleUtility.PickGameObject) which has cascaded out and improved a couple of other tools too (eg right click to select the tile sprite underneath the cursor). Previously I was calculating the grid coordinate of where the mouse clicks, then figuring out which tile to then filter out and select. Silly me!
Consuming mouse clicks has been a bit of a pain, so here's a simple boilerplate you can use to build your own sceneview tools. Hopefully the comments are self explanatory!

I had some issues using middle click, so no idea what's up with that.
Hope that helps someone! Let me know if you have any questions, comments, improvements etc.
