Ace Squared Update Version 0.32

New lighting

Changelog - Version 0.32

Performance & Networking

Hugely reduced input lag for actions like placing voxels or shooting RPGs.
Removed automatic ping kick. Lag compensation is now limited based on the `sv.pingthreshold` cvar (recommended max: 225ms). Players exceeding this threshold will need to lead their shots more significantly.
Voxels now regenerate health gradually over time (`sv.voxelhealth.heal.voxels.count`) after a configurable delay (`sv.voxelhealth.wait.time`) to prevent server lag spikes during regeneration.
Clamped client simulation rate (`sv.player.max.simulation.rate`) to reduce server CPU load caused by high-performance clients.
Fixed block destruction particles causing major performance freezes (Optimization).

Gameplay & Features

Added the new Thunderstrike Shotgun for the Miner class.
Added 'Smooth Mouse' option to the settings menu.
Melee attacks (e.g., Zombie arms, Spades) now use a sphere cast instead of a raycast, making hits easier to land.
Added per-map ambient sound system.
[list]
Added ambient sound to the official Observatory map.

Added map save functionality via the 'savemap' command (saves current world state to .vxl).

Added Light Block system:

Light blocks emit light onto nearby voxels.
Emitted light blends with other nearby light sources.
Includes performance optimizations.
Added an option in settings to disable dynamic light block lighting.

Added a sound effect for grenades colliding with the world or other entities.

Landmine explosions now behave like other explosions:

Spherical shape instead of box.
Damage falloff based on range (no longer always an instant kill).

Rocket turret now uses a simpler box collider for consistency and potential performance improvement.

Disabled players taking damage from falling gravestones.

Blood effects are no longer shown when hitting tents.

Reduced recoil smoothing for increased weapon snappiness.

Visual & UI

Improved bullet visual effects:
[list]
Increased visual velocity.
Now uses a box instead of a line renderer for better visuals.
Added a slight random offset to the visual starting position.

Older killfeed items now fade out gradually.

Reworked scoreboard synchronization. This should fix issues where player entries sometimes appeared invisible.

Fixed class model in the class selection view not being team-colored.

Fixed previously equipped capes sometimes not showing in the UI immediately after joining a server and selecting a class.

Fixed the killfeed icon not displaying correctly for flamethrower kills.

Fixed cycling through previously sent chat messages not working.

[/list]

Fixes

Fixed grenade particle trails sometimes rendering in the wrong position when initially spawned.
Various server security fixes.

Server & Modding

Significant backend reworks to better support modding.
Added server API for the ambient sound system, allowing modders to add custom ambient sounds per map.
Added server API (`WorldProxy:Save`) corresponding to the 'savemap' command.
Added server API (`ClientProxy:GetDisplayUsername`, `DisplayUsername:SetDirty`) for modifying player display names, including colored prefixes/suffixes (related to scoreboard rework).
Added new server hooks: `OnPlayerDied`, `OnWorldLoaded`, `OnDamaged`, `OnKilled`, `OnExplosion`, `OnExploded`.
Added `EntityProxy` API.
Added `PlayerProxy` methods: `GetHeadPosition`, `TryGetViewVoxels`.
Added `GrenadeProjectileSpawner` object API.
