[>r2560]A_Explode(1,..) stopped doing pain to victims

[Edward-san]

See this zandronum ticket.

If you load exploderadius_02.wad, the monsters don't get any pain. It used to work in zdoom r2560 (or also in zdoom 2.5.0). Surely the damage code was changed a lot...

[Graf Zahl]

Are you aware how much damage this attack causes? Precisely - zero! If that caused pain it may have abused a side effect of something, And guess what: There was a minor bug in P_RadiusAttack that let fractional damage slip through which got fixed between 2.5.0 and now. And if I remember correctly it got reported for the precise reason that it caused pain in situations where it shouldn't have.

Also +CAUSEPAIN is now your solution.

[Edward-san]

Hm, according to the bisecting, the 'problem' was introduced since r3523. Sounds strange, doesn't it?

[Graf Zahl]

No, that makes perfect sense. But that particular piece of code doesn't exist anymore, so it cannot be the cause right now.

[Edward-san]

Hm, indeed, because the other wad in the ticket (exploderadius.wad) worked fine with that version. I'll bisect again and let you know.

[Edward-san]

Just one question: if the victim is not exactly at the center of the explosion by 'A_Explode(1,..)', then the damage is always truncated to 0, right?

[Graf Zahl]

That's what I'd imagine.
