Description

Blast damage is calculated incorrectly.
Test case:
Fire a rocket against a wall. It should do 127-128 damage, as in vanilla Doom and PrBoom+. In Doomsday, however, it does 112-113 damage.

History

#1 Updated by gobhuo over 14 years ago

I use Doomsday 1.9 beta 6.8 (fresh installation), addons disabled.

This is due to the fact the damage calculation was changed to incorporate the distance along the world up axis. However, as the rockets are fired from the player's position plus height/2 this means there is additional distance factored into the calculation.

Fixed for 1.9.0-beta6.9 by changing the distance calculation so that the z damage point is the base plus height/2 thereby removing the additional distance when both are equal on the world up axis.

Note that if you want to retain the exact original behaviour you can do so via the console:
