Simple internal C++ cheat for HL2 for GNU/Linux. https://git.2137697.xyz/hl2h/atom?h=master 2026-11-06T15:09:55Z 2026-11-06T15:09:55Z salmonik salmonik@tuta.io 2026-11-06T15:09:55Z urn:sha1:33f5ed9ef58f26c6b3b52cf605dd4311d658a60d 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 2026-10-28T12:02:26Z salmonik salmonik@tuta.io 2026-10-28T12:02:26Z urn:sha1:b212e8e13835cfdc4849a61c1b57146bd0312a29 - Map transitions often leave a non-crowbar weapon active, so the killbot silently does nothing. Log every active-weapon change as a normal `melee: active ... crowbar=0/1` line and toast once suggesting the crowbar. - Recover the crowbar model from the server entity when the client weapon model index is missing/0 after a map change. - Clear the bone cache and aim/silent locks when the local player entity changes (map load/respawn) so stale entity/model data cannot poison melee target selection. 2026-10-28T11:24:10Z salmonik salmonik@tuta.io 2026-10-28T11:24:10Z urn:sha1:16546e5818408f35adc60c2d937cf4541ff7840a - Open /tmp/hl2hake.log once in the library constructor with "w" so each session starts clean, use line buffering, flush each line, and close it via atexit. No more fopen/fclose per message. - Add logd() for verbose diagnostics, enabled only with HL2H_DEBUG=1. - Move ESP/NPC scans, item-prop/item-classification logs, aimbot/silent-aim/ melee/triggerbot/spread details, jumpbug tracking, bone dumps, netvar dumps, cmd-modified and ground-trace noise to logd(). - Keep logf() for lifecycle, config, warnings/errors, GUI open/close, item category/tagging summaries and item-crate detections so crate debugging works without the ESP stream. - Supply crates now respect the max-distance slider (user change), with the stale comment and CONTEXT updated. - Document HL2H_DEBUG=1 in play.sh and CONTEXT. 2026-10-26T19:33:46Z salmonik salmonik@tuta.io 2026-10-26T19:33:46Z urn:sha1:0d0e0602ed89ef6950c27657889a9dcceb0cc697 - validate each SetupBones matrix (finite and non-zero world translation); extra/modded and some vanilla bones (Father Grigori) can be uninitialized and were drawing lines to world (0,0,0) - invalid bones are skipped by the skeleton, hitbox centers and aim points; skeleton children connect to the nearest valid ancestor instead of a dead bone - log the per-model invalid bone count with the first bones diagnostics 2026-10-26T17:26:43Z salmonik salmonik@tuta.io 2026-10-26T17:26:43Z urn:sha1:d45bf3b974171b34655421c8996f1ff37d34178a - head lookup now accepts head-like bone names (teeth, mouth, jaw, face, eye, front, snout, beak) after the HITGROUP_HEAD check (headcrabblack: HCblack.teeth; headcrab/fast: HCfast.wiggle_front) - final fallback is the model's first hitbox center for non-humanoids with no head information at all 2026-10-26T16:02:45Z salmonik salmonik@tuta.io 2026-10-26T16:02:45Z urn:sha1:ab3d725cacbe8cd7153c02faf2d9fe6df7e37949 - Aimbot -> Bones: Head, Torso (chest+stomach), Left/Right arm, Left/Right leg; the aimbot aims at the nearest selected hitbox point on the chosen target (head uses the head hitbox/bone fallback) - Aimbot -> Smoothness: value 1..45 deg/tick, Left/Right in the menu to adjust, persisted as smooth=N; default 5 (previous behaviour) - config: bone_* toggles + smooth under [aimbot] - menu gains a NODE_VALUE type (right-aligned value, Left/Right edit) 2026-10-26T15:46:37Z salmonik salmonik@tuta.io 2026-10-26T15:46:37Z urn:sha1:ccec960a0d53a740eb546a9523811e066a5f118a - g_cam_eye was adding the X component of m_vecViewOffset to Z, leaving the eye ~64 units too low; the aimbot consequently aimed above heads - head_position now prefers the HITGROUP_HEAD hitbox center before falling back to bone names (zombie: headcrab body hitbox) - log the exact head and desired angles for the first few aim ticks 2026-10-26T15:31:44Z salmonik salmonik@tuta.io 2026-10-26T15:31:44Z urn:sha1:d74e4900f8247f2fb20ede70bea4c65c12fd0b55 2026-10-26T15:29:10Z salmonik salmonik@tuta.io 2026-10-26T15:29:10Z urn:sha1:ac578cd21c5f05ebdb6647d595b5bdf5aeefd598 2026-10-26T15:25:28Z salmonik salmonik@tuta.io 2026-10-26T15:25:28Z urn:sha1:1e3b1cabaea62ef0e30ce8a478fb8418aa835229
