ObjectTemplate.HpLostWhileCriticalDamage

MDT description

Some vehicles stop moving and take damage by themselves when heavily damaged. The idea is that if a vehicle is nearly destroyed, it is probably on fire and will soon be fully destroyed on its own. The relevant values in the object's Objects.con file are:

 ObjectTemplate.CriticalDamage 12
 ObjectTemplate.HpLostWhileCriticalDamage 1.5

The CriticalDamage value is the number of hitpoints at or below which the object starts to self-destruct. This is usually about 10-20% of the Maxhitpoints value, though can vary on up to 50%. The HpLostWhileCriticalDamage value gives how many hitpoints are lost per second when in the critical zone.

See the Damage Tutorial for more information.
