Fix audit findings: crash safety, correctness, rendering, performance

2026-11-06T15:09:55Z

Crash/UB: - gate every hook behind an init-stage flag until config/surface/input are ready - publish module maps as immutable atomic snapshots instead of reallocating shared vectors under unlocked readers - validate the %ebp walk in the RandomSeed/RandomFloat hooks against the stack - bounds-check every RecvTable/RecvProp/string dereference with module_range() - preserve the Itanium vtable header when cloning (client, CInput, model render, studio render) - reject negative usercmd sequence numbers; guard config_load against a null section target; cap the bone parent walk; check mprotect; drop PROT_EXEC on the GOT patch; absorb server.so .bss tail Correctness: - filter dormant entities across ESP, aimbot, triggerbot, melee, items and projectiles (slot self-tested against the local player) - reset the server-health latch per map and only latch on valid model indices - bone cache sized for the 128-target scan; set valid=false on every failure; head_position keeps searching past an invalid bone - vischeck steps past glass by probing until clear, and ignores entities owned by the target (held weapons, bone followers) - aimbot: maxs no longer disables it, AABB-aware FOV prefilter, lock hysteresis, lead point re-checked for FOV and visibility - spread: seed hook arms on the no-spread toggle alone; engine toggle only controls the RandomFloat zeroing - resolve m_hOwnerEntity/m_hOwner; NPC lead velocity from the server entity - vector_angles pitch range, point_ground normal test, underwater jump+duck no longer skips combat, semi-auto press/release edge for synthetic fire - item/projectile markers and blast rings refresh origin per frame while discovery stays at 10 Hz; trajectory uses the real m_DmgRadius and honours the blast-radius toggle Rendering/GUI: - one overlay draw per engine frame (FRAME_RENDER_START boundary), fixing alpha stacking and the speed-graph flicker - clipped lines/outlines and ellipsised text instead of drawing past the content pane or shifting over neighbours - dropdown dismissal consumes the click; hover ignores hidden controls - chams: reset AlphaModulate, reference shared materials once, restore prop tint colour; fonts created once per handle - projection uses Source's 4:3 aspect scaling and roll; screen size refreshed each frame; FOV circle gated on the aim toggles, not the bind Performance: - TTL caches for NPC relation, friendly/neutral and damage class - model names memoised per model index - entity pointer -> index cache for the triggerbot (was a 4096-slot walk/tick) Build: - real Makefile with -MMD dependency tracking, debug/release objects and an always-relink rule; build.sh kept as a thin wrapper

Add grenade trajectory, RPG armour priority, empty chargers, mega gravity gun

2026-11-04T22:26:53Z

- Projectiles gets a "Grenade trajectory" toggle. While a frag grenade is held, simulate the weapon_frag throw (1200 u/s forward + 120 z, player velocity, gravity 600) and trace each step with a new trace_solid_segment(); reflect on impact, stop on a slow upward-normal hit, and draw the path, landing cross and a 300-unit blast ring. Verified on :99 (arcs, bounces off the tunnel wall, lands). - With the RPG equipped, armoured NPCs (striders, gunships, dropships, hunter-choppers) sort before normal enemies during target acquisition. Added helicopter/chopper to the ARMORED model list. - Empty health/suit chargers are hidden: read m_iJuice from the server datamap (0 = depleted, -1 = unreadable/fail open). - The citadel supercharged gravity gun (d3_citadel_03, d3_citadel_04, d3_breen_01 via IVEngineClient::GetLevelName) is treated as a normal weapon, so the melee aimbot no longer restricts it to VULNERABLE NPCs.

Chams: working alpha via RenderView blend and a custom VMT

2026-11-04T21:09:14Z

Testing on :99 showed the material $alpha path is a dead end: UnlitGeneric takes translucency from the base texture/vertex alpha, and the debug materials have neither. Follow Amalgam: apply alpha with IVRenderView::SetBlend (VEngineRenderView014 slot 4) around the model draw, saving/restoring it. To have something translucent to blend, write a tiny UnlitGeneric VMT with $model 1 + $translucent 1 + a white base texture to //materials/hl2hake/translucent.vmt (plus a custom/ copy). It is written by a preload constructor so it exists before the material system scans its search paths, then loaded once with FindMaterial. Styles 0/3/4/6 use it when the colour alpha is below 255. Also: - Visible wireframe + through-wall: fill the visible silhouette first so the through-wall pass cannot show in the wireframe gaps, then draw a brightened contour. Style 6 is now "Solid + contour" (recolour + visible edges). - find_modules builds local snapshots and publishes them under a mutex; the setup thread and the server retry could reset the shared vectors live and crash at startup. Verified on :99: Solid + alpha 64 renders a see-through viewmodel, Solid + contour shows a blue fill with bright blue contours, Additive is a translucent coloured glow and Fullbright is a white additive glow.

Chams: per-colour alpha and a softer viewmodel additive base

2026-11-04T18:36:24Z

- Colour picker gains an optional alpha bar (checkerboard preview, #RRGGBBAA readout); add_color_alpha is used for the chams colours. Chams colours are now r,g,b,a and chams_apply sets $alpha plus MATERIAL_VAR_TRANSLUCENT when alpha < 255. Config stores vis_a / inv_a / vm a. - The additive viewmodel base is now a faint translucent tint (alpha/8) instead of an opaque fill, so additive/Fullbright stay see-through and the viewmodel no longer becomes a solid blob. Fullbright whitening reduced to 25% so blue stays blue instead of turning lavender.

Chams: per-relationship, visible/invisible styles and viewmodel

2026-11-04T17:58:13Z

- Hostile/neutral/friendly each have independent visible and through-wall settings: enable, style and colour. Viewmodel has its own enable/style/colour. - Styles: Flat, Wireframe, Additive, Solid, White, Fullbright, Glow outline. Additive uses the model solid material + ADDITIVE flag (the VGUI additive was invisible on NPCs). White/fullbright are solid-based, so the viewmodel no longer disappears/checkerboards. Glow outline adds a wireframe contour pass for depth. - Config: [chams] active/bind, [chams_hostile|neutral|friendly] vis/inv settings, [chams_vm]. GUI sections for each group.

Chams: model-safe styles and a dedicated viewmodel material

2026-11-04T17:17:55Z

VGUI/white materials do not draw skinned models, so every viewmodel style except the model debug one made the hands/weapon disappear. Use model debug materials for all styles: wireframe, additive vertex colour, translucent single colour, translucent vertex colour, MRM fullbright. The viewmodel always uses debug/debugtranslucentsinglecolor. A missing style now falls back to that material instead of vgui/white.

Chams: exact material styles, GUI dropdown, viewmodel hookup

2026-11-04T17:15:18Z

- world_find_material now tries the exact requested style first (resident, then FindMaterial) before falling back to debugwhite/vgui white. The old candidate scan returned vgui/white for every style, so all materials looked flat. - Add a real CK_DROPDOWN control (overlay list, outside-click close, config save) and use it for the Chams material selector. - Chams viewmodel toggle included in config/UI.

Chams: material styles and viewmodel support

2026-11-04T17:08:07Z

- Material selector 0..4: debugwhite, debug wireframe (ignorez), vgui white_additive, debugtranslucentsinglecolor, vgui/white; cached per index with a debugwhite fallback. - Add "Viewmodel (hands/weapon)" toggle; viewmodel entities (class contains viewmodel or model path /v_...) get a normal-depth chams pass. - [chams] gains viewmodel= and material=.

Add chams

2026-11-04T16:51:20Z

- Hook IVModelRender::DrawModelExecute (VEngineModel016 slot 19) and force models/debug/debugwhite for NPC models, identified by ModelRenderInfo_t::entity_index. - Two passes: MATERIAL_VAR_IGNOREZ through walls, then normal depth, with IMaterial::ColorModulate for the configured colour; restore the shared material's flag/colour afterwards. - Material lookup via the IMaterialSystem list, FindMaterial fallback. - New Chams feature/card with Through walls and colour; [chams] config. - Remove the temporary ammo/projectile/fuse diagnostics.

Add usable item filter, projectile ESP and gravity-gun melee

2026-11-04T13:28:21Z

- Items: "Only if usable" hides health tags at full health and armor at full suit. Health ceiling is the server player's m_iMaxHealth; armor uses the server m_ArmorValue against HL2's 100 cap. Fails open when unreadable. - Projectiles: new Visuals feature/card for thrown grenades, RPG rockets, helicopter bombs and AR2 balls. Fuse from server m_flDetonateTime vs engine time; radius from m_DmgRadius with per-type fallback; optional 24-segment radius ring and FRAG timer label. - Melee: the killbot now handles the gravity gun as well; only VULNERABLE targets, 1200-unit range, primary attack to launch the held object, and no aim-punch compensation because the launch uses EyeVectors. - Server/netvars: m_ArmorValue, m_flDetonateTime, m_DmgRadius.
