Area-of-effect blast on missile detonation, from the T0 source EXPLODE.cpp:50-254
(@0042fad0) + the arcade decomp. Fires on ANY missile impact (world or mech) --
the +0x360 gate sits in the Missile::Perform collision branch (part_013.c:10097).
Only missiles splash; the AC's tracer is not a Missile.
Radius source CORRECTED: it is the ROUND's own GameModel (type-0xf) +0x50, seeded
from the launcher's linked AmmoBin ammoModelFile @0x1e8 (part_013.c:8778) -- NOT
the launcher's ExplosionModelFile (which resolved to 0). Live-resolved radius = 30
for both MP missile launchers; 0 for AC/Emitters.
Burst falloff = baseBurst / dist^exp floored at 1 (arcade 1.25 = decomp 0x3ff40000;
WinTesla EXPLODE.cpp:209 drifted to 1.2f). damageType/amount pass through unchanged;
only burstCount, radial damageForce, and impactPoint are set. Excludes shooter +
direct victim; dist>radius gated; delivered via msgmgr (cross-pod) or Dispatch.
New: BTResolveSplashRadius / BTApplySplashDamage (mech4.cpp), hooked at both the
world-impact and contact detonation paths; BTAmmoRoundModelResource bridge
(ammobin). Env: BT_SPLASH_LOG, BT_SPLASH_TEST (synthetic near-miss), BT_AF_MISSILE
(missile autofire). Verified: near-miss dist=15 -> 1 burst to a bystander; live
missiles detonate + exclude the direct victim; AC does not splash; no crash.
Deferred (T3): per-player enable sub-gate missile+0x360 = BTPlayer+0x264 (writers
read as a per-frame toggle, not a config flag) -- port treats SplashRadius>0 as the
enable. KB: combat-damage.md + open-questions.md updated.
