Why do overlapping Area2D events fire in wrong order?

Default priority 0 across all areas; engine picks scene-tree order. Set priority on each Area2D to control which emits first.

Damage zone over heal zone: damage should resolve first. Set damage priority 10, heal priority 0; damage events fire first.

Tied priorities resolve by tree order. Reorder children in scene tree, or set distinct priorities to be deterministic.

Fix: Godot Multiple Area2D Overlaps Wrong Order

Quick answer: Set per-area priority. Higher priority area emits before lower.

Player walks into stacked damage + heal zones. Heal happens first; player ends with full HP from a damage zone. Order matters.

DamageArea (Area2D):
  priority = 10

HealArea (Area2D):
  priority = 0

# Damage signal fires first; heal second.

Distinct priorities determine emission order. Same priority falls back to scene-tree order.

Connect to body_entered on each Area2D. Damage logs before heal. Without priority: order varies.

“Higher priority. First emit.”
