A physics-grounded ruleset for placing assets on 2.5D isometric game maps so scenes read as believable instead of amateur. It enforces gravity contact, leaning angles, center-of-mass stacking, spill direction, material-specific effects, and layer hierarchy through a three-layer validation: physical reality, narrative logic, and visual balance, that every asset must pass.

A floating barrel ruins a scene faster than any bug. Every map asset passes three validation layers (physics, narrative, visual balance) before it earns a place:
- Reads the asset's AssetDefinition ScriptableObject first: pivot (must be bottom-center 0.5, 0), collision box size and offset, material type, placement padding radius, layer tier and the list of required secondary assets.
- Runs Layer 1, physical reality: does the asset touch the ground (no floating objects, ever), is a leaning object at 55-75 degrees toward the surface it leans on, and does a stacked object's center of mass sit inside the contact surface below it? The LeaningAngleValidator flags anything under 15 degrees as a hard physics violation in the Inspector.
- Runs Layer 2, narrative logic: why is this object here, who left it, and is every primary asset linked to at least one secondary (a big tree gets rooted ground, mossy stones, a leaf pile)? A random prop with no story connection is rejected.
- Runs Layer 3, visual balance: density compared to neighboring regions differs by at most one level, repeated sprites carry rotation and scale variance, and every shadow follows the single global light direction enforced by ShadowCaster2D.
- Sweeps the scene with the CollisionOverlapDetector: any two solid colliders whose bounds intersect (triggers excluded) are logged as errors, and the post-save hook blocks the scene with exit 2 until they are fixed.
- Closes with the 12-item checklist from the rule file. An asset passes only at 12/12; one fail means reject with root-cause feedback, which is also the gate the game-qa agent runs before any build.

-
Is this an automated check or rules I apply by hand?
It's a ruleset you validate layouts against: placement, leaning angle, collision overlap. You can audit a scene whether you built it by hand or generated it; it judges the layout, it doesn't move objects for you.
-
Does it actually simulate physics, or is it a set of rules of thumb?
It's grounded rules, like believable leaning angles and no floating or overlapping geometry, not a live physics engine. That's deliberate: the goal is catching the placement errors that make a scene read as amateur, fast, without a simulation.
-
Will this make my map look good?
It makes a map look believable, with assets sitting where physics says they should, but composition, lighting, and color are a separate craft. It's also scoped to 2.5D isometric maps specifically.
