TakeDamage can only give 0.5 hearts

Which of the three functions are you using? In C++ there are these declarations (all exported to Lua):

Code:

/// Makes this pawn take damage from an attack by a_Attacker. Damage values are calculated automatically and DoTakeDamage() called
void TakeDamage(cPawn & a_Attacker);

/// Makes this pawn take the specified damage. The final damage is calculated using current armor, then DoTakeDamage() called
void TakeDamage(eDamageType a_DamageType, cPawn * a_Attacker, int a_RawDamage, double a_KnockbackAmount);

/// Makes this pawn take the specified damage. The values are packed into a TDI, knockback calculated, then sent through DoTakeDamage()
void TakeDamage(eDamageType a_DamageType, cPawn * a_Attacker, int a_RawDamage, int a_FinalDamage, double a_KnockbackAmount);

So I think something like TakeDamage(dtEnvironment, nil, 4, 0); should call the middle variant, giving 2 hearts of environmental damage with zero knockback.
