Here comes a big one. This update improves stability and performance (especially when there are a lot of aliens at once) and a whole lot more. Special thanks to the contributors to RDA, especially Orange, who contributed many of their patches from that mod.

Stability and Performance

• Killing a large number of aliens at once no longer crashes the game.

• The death animation of Shieldbugs no longer causes rare client crashes.

• Long play sessions will no longer crash due to particles array overflow.

• VScripts no longer crash server when creating a lot of entities in challenges.

• Cleaned up memory leaks.

• Improved performance by removing unnecessary calculations throughout the codebase.

• Disabled some spammy developer warnings by default.

• Improved the performance of rm_welcome_message.

• Reduce the amount of client-server network errors

Aliens

• Fixed Buzzer poison getting stuck if a player died while it was active and did not switch to another marine.

• Fixed Parasites and Xenomites being immune to blast damage when fully submerged in water.

• Fixed Drones getting stuck when dismounting info_node_climb.

• Fixed a case where Drones would navigate to the wrong location when pathfinding failed.

• Parasites should no longer appear to be growing outside of their egg or spawn at the wrong place when jumping out of an egg with unusual angles.

• Mortarbug shells no longer block moving platforms.

• Buzzers properly enter and exit the sleep state when far from players.

• Drones will no longer "warp" past marines on challenges with very high drone acceleration.

• Aliens with moveclone set do not trigger physics collision code. This improves performance on maps like Cargo Elevator that use aliens in a cinematic way.

Weapons

• Extremely short range shots will no longer cause incorrect decals or impact animations.

• X33 Damage Amplifier and IAF Heal Beacon no longer bounce in place or fall through the floor when placed on a moving platform.

• M478 Proximity Incendiary Mines no longer fall through certain types of dynamic floor.

• ML30 Laser Trip Mines no longer explode when touched by an invisible character.

• SM75 Combat Flares and TG-05 Gas Grenades no longer collide with NPC Clip.

• Fixed an issue where grenades would aim incorrectly if the marine had been hit from behind very recently.

• Fixed collision inconsistencies between mines and various types of throwables.

• The beam of the mining laser no longer gets stuck if the weapon is deleted by a script.

Misc

• Fixed doors getting stuck with negative health if they were killed from the side they were dented towards. Extremely high damage can correctly knock down a door in one hit.

• Sentry bases now use a different skin number for each type of sentry.

• Made the cheat convar asw_unlock_all_weapons available outside of debug builds.

• Added asw_create_generic_emitters_for_drone_gibs, which can be set to 0 to disable some graphics.

• r_drawsprites and r_drawropes are no longer marked as cheats.

• Added statistics support for the Football map.

• Fixed exploits involving client commands (cl_campaignsas, cl_kickvote, etc.)

• Fixed the warning message for an invalid unburrow idle activity.

• Fixed a rare case where a marine dying would not automatically spectate the next marine.

• Fixed the calculation of the fast hack time for 4-wire hacks.

• Fixed scrolling the difficulty from Insane using keyboard or a controller going to Easy rather than Brutal.

• Fixed not being able to draw on some parts of the map in the mission failed debriefing.

• Improved physics calculations when a marine is stuck on a box or near a spawning alien.

• Increased engine limit for pseudosounds, which are used for NPC AI.

• Reduced the delay when starting a mission.

• Added HUD support for having more than max HP.

VScript Functions

• void CBaseEntity::SetParent(handle parent) - sets an entity as another entity's move parent; faster than calling the input from VScript

• void CBaseEntity::ClearParent() - clears the entity's move parent; faster than calling the input from VScript

• handle FindNearestNPC(Vector Position, bool CheckZCoordinate, float Radius) - returns the nearest character (marine, colonist, or alien) to the given coordinate

• void CASW_Grenade_Cluster::Disable() - disables the grenade's timer

• void CASW_Grenade_Cluster::Enable() - re-enables the grenade's timer

• void CASW_Grenade_Cluster::EnableWithReset() - re-enables and resets the grenade's timer to its original duration

• void CASW_Grenade_Cluster::ReflectBack() - reflects the grenade to approximately where it was fired from

• void CASW_Grenade_Cluster::ReflectRandomly() - reflects the grenade to a random direction

_The VScript functions added to CASW_GrenadeCluster are also available as Hammer inputs.
