I’ve a script that takes in a PNG bitmap (e.g. 8×8) and, reading from that, populates the grid with cells where alpha > 0.
The script runs in
Awake(), so it can only be seen in Play Mode. I want it to always appear in the scene, even in Edit Mode.
I know of the
(ExecuteInEditMode) attribute, as well as the
OnValidate() callback. I don’t know which is better to use, though, or what pitfalls to avoid.
Additionally, in the past, I created a level generator that created a mesh, which I saved as an .asset with a customer editor button. The .asset was then loaded from inside the script. However, if possible, I’d like a more elegant — and automatic — solution.
I’m using Unity 2018.4, and the grid is isometric. (I’m not using Unity’s built-in Tilemap.)
