If this projectile has been in existence for longer than the amount of time specified in its Delay Before Automatic Detonation property, this value determines its likelihood of disappearing during any given tick thereafter. For example, a value of 1.0 would force this projectile to disappear as soon as its Delay Before Automatic Detonation period has expired. There are 30 ticks per second. This property does not apply to laser projectiles.
