editor rework & map editing groundwork

been working on the editor again

this update was mostly about cleaning up the editor architecture so I can actually keep adding features without everything turning into spaghetti. I also finally started laying the groundwork for proper map editing.

changes

editor

reworked the editor state system.

instead of instantly swapping between states, transitions are now deferred until a safe point during the update loop. this makes switching between Edit, Play, Map Edit, and the Hub a lot cleaner, and the editor now remembers which editing mode you were in before hitting Play.

(i’ll admit… i was getting a bunch of weird, seemingly unexplainable crashes before eventually realizing my mistake was instantly switching states while things were still being updated/rendered…)

also moved more UI responsibility into the individual states instead of having EditorLayer decide how everything should be drawn.

map editor

started putting together the map editor.

currently i have:

• map hover and tile selection working
• placeholder Paint / Erase / Select tools
• the beginnings of a tile palette system
• a placeholder tile editor panel

the actual editing logic isn’t implemented yet, but the foundations are there now :)

asset picker

ripped out the old “open a native file dialog for every asset field” flow.

instead, the editor now lets you pick existing textures, meshes, materials and shaders directly from the ResourceManager, which is a lot nicer to work with and also avoids accidentally importing duplicate assets.

(the old workflow would happily create a brand new object every time you imported something… which was fine for testing, but definitely wasn’t something i wanted to keep)

rendering

fixed a few editor rendering issues while i was at it.

• materials with invalid shaders now fall back to the default shader instead of silently disappearing
• fixed some edge cases with framebuffer entity picking
• currently unused, but functional shader hot reloading tests

misc

• smoothed out editor camera movement and zoom
• added a few helper utilities for the map editor
• reorganized the editor UI code a bit

doesn’t look massively different in screenshots, but makes future work alot easier/cleaner

map painting is next ?..
