Migration notes: godot-genre-moba

Incremental upgrade for topics this skill covers. Apply one hop, stabilize/test, then next. Never skip hops.

If the project is < 4.0, follow godot-version-migration era bridges (legacy → 3→4) until 4.0, then these hops. Official 3→4: Upgrading from Godot 3 to Godot 4.

4.0 → 4.1

Official: Upgrading to Godot 4.1

• NavigationAgent2D/3D.set_velocity → velocity property — retune minion/lane agent flow.
• time_horizon split into time_horizon_agents and time_horizon_obstacles.
• NavigationAgent3D.agent_height_offset → path_height_offset; ignore_y removed.
• NavigationObstacle*.estimate_radius removed; get_rid → get_agent_rid.
• NavigationServer*.agent_set_callback → agent_set_avoidance_callback.

4.1 → 4.2

Official: Upgrading to Godot 4.2

No skill-relevant breaking changes for this hop.

4.2 → 4.3

Official: Upgrading to Godot 4.3

• TileMap layers → TileMapLayer nodes — migrate Fog-of-War grid masks before relying on per-layer APIs.
• SceneMultiplayer caching protocol incompatible across versions — upgrade server and clients together; add version checks.
• AStar2D/3D/Grid2D.get_*_path gain allow_partial_path.
• NavigationRegion2D experimental avoidance props removed with no replacement.

4.3 → 4.4

Official: Upgrading to Godot 4.4

• NavigationServer2D/3D.query_path gains optional callback — async pathing under combat load.

4.4 → 4.5

Official: Upgrading to Godot 4.5

• Node.get_rpc_config → get_node_rpc_config — audit ability/cooldown RPC configs.
• Nav regions update asynchronously by default — expect brief lane nav desync after map edits.
• Navmesh merge order changed; edge merge errors may surface — fix overlapping brush navmeshes.

4.5 → 4.6

Official: Upgrading to Godot 4.6

• Retune Environment glow/fog if the genre leans on bloom-heavy looks (ability VFX, river glow).
• AStar*.get_point_path / get_id_path return empty path when from_id is disabled/solid.

4.6 → 4.7

Official: Upgrading to Godot 4.7

• Confirm project stretch mode and AudioStreamPlayer.area_mask after opening in 4.7.
• AudioStreamPlayer.area_mask default is 0 — set mask for bush/river zone audio and ability SFX buses.
• Mouse/keyboard device IDs are InputEvent.DEVICE_ID_MOUSE / DEVICE_ID_KEYBOARD (not 0) — retune ability hotbar input checks.
