Description

Operating System

Windows x64

DevilutionX version

Custom build (please specify commit ID)

Describe

If a player is attacked with a monster's charge attack (such as from a Rhino or Goats using Rhino AI) and the player is dead, their corpse will be pushed back a tile (if possible) by the attack.

Encountered on commit b979b48bd of DAPI integration PR.

To Reproduce

  1. Go to a floor with enemies that use charge attacks that can cause knockback.
  2. Die with some of the enemies far enough away to trigger the attack and with a clear line of sight
  3. Wait for them to use the charge attack on your corpse.

Expected Behavior

Players should not be impacted by knockback after death.

Research direction
Investigate the knockback logic in monster AI, particularly the Rhino charge attack. Look for where knockback is applied to determine if a dead player check is missing. Review comments on the issue for pointers to relevant source files.
