Summary0000277: Bouncing collision detection on the Z axis
DescriptionWith ANY bouncing flags, if a projectile hits the top of an actors hitbox, it won't bounce away, rather, it will fall inside the actor, losing all momentum.

This will happen if

a) the bouncer has +BOUNCEONACTORS and hits a shootable actor
b) the bouncer is a regular projectile which hits a nonshootable actor
c) pretty much any time it doesn't enter its death or crash states.

This issue has not been fixed in zdoom or gzdoom.

Steps To ReproduceTake one bouncing projectile, fire it at an angle which will cause it to land on an actor from above. ???, profit.
Additional InformationExample wad: [url]http://www.mediafire.com/?7qs106ou08vnq0c[/url]

A bouncer with the +CANPASS flag is capable of recognizing an actors Z height, however, it still loses all vertical momentum when it touches one.

Yes, I just thought it might be worth adding to the new bug tracker.

This should be closed as it is not a Skulltag issue. ALLOWBOUNCEACTORS is not even in Skulltag yet, so the example wad breaks.

* Fixed: Bouncing missiles landing on an actor would just stop rather than bounce.

'http://zdoom.org/Changelog/3597/files [^]'

* Implicitly set MF2_PASSMOBJ when BounceType is used in an actor definition so that actors under or above the bouncer can be checked for bouncing.

'http://zdoom.org/Changelog/3598/files [^]'

* On second thought, using FloorBounceMissile() for bouncing off the top of an actor might not be the best idea.

I tested the example wad provided in 3.0, the actors bounce successfully on the shootable soulspheres, indicating that this is fixed in 3.0.
