Change log/5.15

Santa Garg is here!

Despite being locked in my childhood bedroom at my parents' house while screaming children pound on the door, we've managed to assemble a holiday update! This update features custom HUD elements, numerous bug fixes, and a new map by JPolito and GeckonCZ.

1 New Map - They Hunger: Escape

They Hunger: Escape, created by JPolito and GeckonCZ, has been released with the game. The map features survival gameplay in which players must find three randomly placed items and bring them to a broken down truck. The truck must then be repaired and used to escape from the town before the timer runs out and the military arrives to 'purge' the town.

At the start of each round, each player is assigned to a random 'civilian' role. Rounds last seven to eight minutes (depending on difficulty mode). Once the timer runs out, the military parachutes into the town and will destroy the vehicle if all of the items have not yet been brought to it. It is still possible to repair the vehicle and escape after the timer runs out, but it is exceedingly difficult. 4-8 players are recommended.

2 Notable changes

Added support for custom HUD elements (generic sprite, numeric display and time display). Exposed the new functionality through the AS API.
New map: "They Hunger: Escape".
Scripted weapons can now drop ammo.

3 Code

3.1 Game library

Added "+inventory"/"-inventory" command pair that will toggle the inventory screen.
All impulse commands (including flashlight) and the +use command are no longer blocked by certain weapon actions (anything that uses the m_flNextAttack variable would cause this issue).
Changed MAX_AMMO_TYPES from 32 to 64 for scripted weapons (i.e. the CoF weapon pack). Merged MAX_AMMO_SLOTS and MAX_AMMO_TYPES definitions (both served the same purpose).
Fixed corpses blocking monstermakers/squadmakers.
Fixed issue where chat messages sent right before a map change wouldn't get printed to the console.
Fixed issue with muzzle sprites not appearing long enough for players that have low framerates
Fixed issue with skill CVARs not being set correctly when changed via trigger_setcvar.
Fixed the "Voting menu doesn't add players as they join" issue.
Fixed the confusing "You must wait X seconds before you can call for aid." message that appeared when "getextras" command was used too soon.
Flashlight now uses CHAN_AUTO instead of CHAN_WEAPON to play the "click" sound. This should prevent it from interrupting weapon sounds.
Removed support for resolutions lower than 480p.
Removed the "impulse 99" command and the corresponding E3 1998 logo functionality.
Skill CVARs can now be changed on the fly (directly from console).
The message that appears when players enter observer mode will now mention reviving only if the player didn't get gibbed.
Unlinked MAX_WEAPON_POSITIONS and MAX_WEAPONS definitions again to allow for up to 20 weapons per bucket. This way all 9+1 weapon buckets are available and compatibility with existing scripts is maintained.
[func_tank] Players can now leave tanks by pressing USE key again.
[func_tank] Players can use impulse commands (including flashlight) while operating tanks.
[path_track] Added new keyvalue "maxspeed". Sets new maximum train speed. If the train is traveling too fast, its speed will be set to the new allowed maximum.
[path_track] Added new keyvalue "newspeed". Same as the legacy "speed" keyvalue but works correctly with controllable trains.
[trigger_camera] Added key input callback.

3.2 Heads-Up Display

"mp_survival_voteallow" CVAR can be used from map config now.
Added "HIDEHUD_CUSTOM_MAPS" and "HIDEHUD_CUSTOM_PLUGINS" flags. Can be used to hide all custom elements from a given group.
Added HL2-like auto-hide feature for the weapon selection menu. This should prevent the situation with players running around with the weapon menu active and unintentionally switching to a different weapon during combat.
Added support for custom HUD elements (generic sprite, numeric display and time display).
Fixed alignment of many HUD elements.
Fixed alignment of multiline HUD messages if negative screen coordinates are used.
Fixed an issue where the ammo bar in the HUD weapon selection would not be visible if the weapon had only secondary ammo left.
Fixed an issue where weapons that don't use any ammo would be drawn red in the HUD weapon history.
Fixed position of the "say:" input line, so it's no longer displayed in the very top left corner of the screen.
Fixed weapon slots not being cleared properly. Fixes issue where weapon selection would break occasionally.
Health, suit and ammo indicators can now display 4 digit values.
Health/suit power value is now clamped correctly, so the value displayed on HUD doesn't roll over if it's too high.
In-game chat can now display up to 12 lines (6 by default; can be customized via hud_saytext_lines CVAR).
Increased the weapon slot count from 7 to 10 (for scripted weapons). Slots #6 - #8 are only visible if there are weapons assigned to them. Slot #9 is always hidden and is reserved for special weapons (minigun, shockrifle).
Inventory items can use custom HUD sprites. Set by a new "item_icon" keyvalue. Expected sprite size is 72x72px. If the player holds items of more than one type, the default item inventory icon will be used.
Made the cl_showstats debug info slightly more compact.
New CVAR: "hud_alpha_default"; can be used to customize default transparency of HUD elements. (range: 0..255; default: 160)
New CVAR: "hud_alpha_max"; can be used to customize transparency of active HUD elements. (range: 0..255; default: 255)

New CVAR: "hud_draw"; enables/disables drawing of the HUD. (values: 0/1; default: 1; the value is not saved)
New CVAR: "hud_hidecustom"; can be used to hide custom HUD elements. Just in case some server operators do something naughty with the feature. (values: 0 - show all, 1 - hide elements created by map scripts, 2 - hide elements created by server plugins; >=3 - hide all)
New CVAR: "hud_saytext"; enables/disables drawing of the in-game chat. (values: 0/1; default: 1; the value is not saved)
New CVAR: "hud_selection_fadeout"; sets the time it takes to fade out before it automatically closes. Default value: 0.5 seconds. If set to 0 the fade out effect will be disabled.
New CVAR: "hud_selection_timeout"; sets the time it takes before the selection menu starts fading out. Default value: 1.5 seconds. If set to 0 the auto-hide feature will be disabled.
New CVAR: "mp_suitpower"; Can be used to disable HEV suit power (armor) and hide it from the HUD. Values: 1 - enabled (default), 0 - disabled.
Numeric displays will show + sign behind the number if the value is "out of range".
Player names in chat are now displayed with a slightly different color.
The ammo bar in the HUD weapon selection turns red instead of disappearing if the weapon has no ammo except for what is left in the weapon itself.
The ammo display will now flash even for weapons that are not using magazines.
The chat "block" is now positioned at the center of the bottom half of the screen. If there isn't enough space, the chat is moved up to clear the health/suit power displays.
The weapon selection will automatically close if the player picks up a special weapon.
Tweaked the HUD layout for a more consistent look.
Weapon history slots are now initialized properly, so the very first ammo/weapon pickup will be always rendered at the bottom of the weapon history list.

RegisterWeapon() can be used to specify classname of the dropped ammo and ItemInfo to specify the amount.
Any weapon can now use the iClip2 ammo display (enabled by setting iClip2 >= 0).

Exposed Adam's "Entity compounded effects/modifiers" through AS API.
Added new methods BlockWeapons(),UnblockWeapons() and GetWeaponsBlocked() to CBasePlayer class. Exposed through AS API.

Exposed CBasePlayer::DeployWeapon() through AS API.
Changed signature of CBaseMonster::FBecomeProne() to CBaseMonster::FBecomeProne( CBaseEntity * pOther ).

Renamed MAX_AMMO_SLOTS AS definition to MAX_AMMO_TYPES and changed the doc. string to be more descriptive.
CBasePlayerWeapon::AddPrimaryAmmo() and AddSecondaryAmmo() returns amount of actually added ammo instead of returning boolean value whether any ammo was added or not.
Fixed name of the CBasePlayerWeapon::AddSecondaryAmmo() method (it was mistakenly exposed as AddPrimaryAmmo() in the previous versions)
Added new item flag ITEM_FLAG_IGNOREWEAPONSTAY - used by the minigun (instead of a hard coded exception) and can be used by scripted weapons as well.

[Barnacle] Barnacles will now ignore large XRACE monsters.
[Barnacle] Fixed the issue where barnacles were unable to kill monsters that take reduced damage if the damage type is "slash" (i.e. pitdrones).

All weapon and ammo world models will animate now if the model supports it (i.e. the spore launcher).
Changed how mapper placed items are determined. Fixes an issue where weapons with movetype set to MOVETYPE_FLY would start spinning when respawned. Also fixes the spinning weaponbox on hl_c16_a1.
Crowbar, wrench, medkit, barnacle grapple and glock will now appear in the HUD weapon history when picked up.

Fixed an issue were players could pick up satchels dropped by somebody else and deploy them to get over the limit of 5 deployed satchels.
Players can drop secondary ammo now ("dropsecammo").
Players can no longer "steal" dropped weapons if they already have the same weapon. They will instead take the ammo from it and only as much as they can carry. No weapons or ammo is wasted this way.
Players can no longer pick up dropped ammo/weapons if they already have max. amount of the particular ammo type.
Players can no longer steal thrown crowbar if they already have one.
Scripted weapons can drop ammo now.
The "ammunition depleted" HEV sound is now played for uzi, M16, gauss gun, gluon gun and minigun as well.
The Classic mode shotgun is now forced to use the double-barrel fire mode as its secondary attack (the weaponmode_shotgun CVAR is ignored).
Weapons directly given to a player (i.e. via map config or "impulse 101") now ignore the "weapon pickup" delay.
Weapons dropped by NPCs are an actual weapon entities now (instead of a reskinned weaponbox entity).

[Gluon Gun] The gluon gun beam is no longer slightly off compared to the crosshair position.
[Gluon Gun] The gluon gun will reset back to the idle animation correctly when the player runs out of ammo and keeps holding the attack button (this will hide the blue light reflection effect that is part of the weapon model).
[Gluon Gun] Tweaked the gluon gun beam effect a bit. The gluon cloud sprite is now rendered even if the target entity can't take damage.
[Gluon gun] Removed "sk_plr_egon_narrow" skill CVAR (unused since HL beta).

[Uzi] The uzi uses two different HUD sprites again (single uzi and akimbo). It changes when a second uzi is picked up/dropped (the actual weapon mode doesn't matter here).
[item_inventory] "effect_block_weapons" set to 1 should work reliably now (No view model glitching, no weapon switching).
[item_inventory] Fixed an issue where the item_inventory entity would fly in a random direction when dropped.
[item_inventory] Fixed double-not on the ignore trigger check, which meant that "if not not ignoring triggers, fire the triggers".
