開啟 RangedRange3x 後弓箭等拋射物「根本射不到」站著不動的敵人。 根因為彈道幾何：水平抵達時間為與距離無關的常數 4/ISF（約 2.67 秒）， 垂直飛行落地時間為 2×emit/ysub（弓箭約 2.47 秒），因此每箭固定落在 目標距離的約 92.5%，形成「射短≈7.5%×距離」的系統性偏差。原版射程下 7.5% 尚在傷害半徑內，三倍射程時射短距離同步三倍、遠超傷害半徑。 依使用者要求不更動傷害半徑（w*_drad），改以提高拋射初速解決： RangedRange3x 啟用時 EparaPatcher 將 cl_epara.ini [ProjectileInitSpeedFactor] 乘以 InitSpeedReachMultiplier=1.08 （1.5→1.62），使 4/ISF 對齊弓箭飛行時間、射短比例趨近 0，拋射物 即可覆蓋放大後的射程（並縮短飛行時間降低移動目標閃避）。偵測不受影響 （RangedRange3x 由 objdef 射程欄位回讀，不讀 epara）。1.08 屬靜態逆向 推導，正式倍率仍待實機校準。新增 round-trip 測試並更新既有 epara 測試。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Brrn8kwp6d2HX3nZzBhGAc

RangedRange3x（三倍射程）後，弓箭等拋射物「根本射不到」連站著不動、原版可以直接命中的敵人。這與先前修過的視野／鎖定問題（AI_HANDOFF 已記錄）是不同的第二個問題。根因（彈道幾何）
依
docs/reverse-engineering/projectile-ballistics.md的靜態逆向模型：4/ISF（原版 ISF 1.5 → 約 2.67 秒）。2×emit/ysub（弓箭約 2.47 秒），同樣與距離無關。T_fall/T_arrival ≈ 92.5%，形成「射短 ≈ 7.5% × 距離」的系統性偏差。原版射程下 7.5% 的射短尚在傷害半徑（弓箭
w_drad= 45）之內，敵人被打中；三倍射程時射短距離同步變三倍、遠超傷害半徑，箭落在敵人前方 → 「根本射不到」。修法（依使用者要求，不更動傷害半徑）
RangedRange3x啟用時，EparaPatcher將cl_epara.ini的[ProjectileInitSpeedFactor]乘以InitSpeedReachMultiplier= 1.08（1.5 → 1.62），使4/ISF下降對齊弓箭飛行時間，射短比例趨近 0，拋射物即可覆蓋放大後的射程（並縮短飛行時間、降低移動目標閃避）。EparaPatcher.GetPatchedBytes新增rangedRange3x參數，重構為可獨立套用 variance / init-speed 兩個區段。PatchEngine傳入options.RangedRange3x。RangedRange3x由 objdef 射程欄位回讀，不讀 epara（與既有 variance 補丁一致）。測試
Epara_range3x_raises_init_speed_so_projectiles_reach_extended_rangeround-trip 測試。Epara_accuracy_patch_...測試簽章（未開三倍射程時 ISF 維持 1.5）。待辦 / 注意
1.08屬靜態逆向推導（與ArcEmitMultiplier同性質），正式倍率仍待實機校準——三倍射程的命中窗口很窄（弓箭約 ISF 1.62 ± 0.05）。此常數集中於EparaPatcher.InitSpeedReachMultiplier，易於調整。🤖 Generated with Claude Code
