ZDoom

What I said before. If you just dump an incomplete feature in here and don't respond to feedback I see no reason to add it.

As it is I won't add it. There's some issues here:

1. Why only players? That restriction makes no sense.
2. Any new actor variable involved needs to be saved in savegames or there'll be some problems,

Yes.

What should i use to create patches now? Just "svn diff > something.txt"?

patching file actor.h
Hunk #1 succeeded at 330 with fuzz 3.
Hunk #2 succeeded at 817 with fuzz 3.
patching file p_map.cpp
Hunk #1 FAILED at 1024.
1 out of 1 hunk FAILED -- saving rejects to file p_map.cpp.rej
patching file p_mobj.cpp
Hunk #1 succeeded at 5303 with fuzz 3.
patching file thingdef/thingdef_data.cpp
Hunk #1 succeeded at 233 with fuzz 3.

kgsws, let me say this: don't use "diff -rup".
I tried to apply the patch in the src directory with this command:
"patch -Np2 -i ../hitself.diff -F5 --ignore-whitespace"
and the result was:
[code]
patching file actor.h
Hunk #1 succeeded at 330 with fuzz 3.
Hunk #2 succeeded at 817 with fuzz 3.
patching file p_map.cpp
Hunk #1 FAILED at 1024.

patching file thingdef/thingdef_data.cpp

[/code]

Now I re-created the patch ("svn diff > canhitshooter.txt" ) with the following changes:
- Change the name HITSELF to CANHITSHOOTER;
- Moved the "return" attached to the "if( )" in p_map.cpp in a new line for a better readability.

The compiling is fine, so here it is.

[attachment=0]canhitshooter.txt[/attachment]

Feel free to change name :)

Or even +CANHITSHOOTER to indicate that it can do it but isn't compelled to. ;)

(ie It wouldn't turn around and try to target the shooter simply because it had the flag.)

Wouldn't HITSHOOTER be a more intuitive name? (Seeing as my first thought, upon seeing the title, was "why would you want a projectile to hit itself?" :lol: )

This flag will allow projectiles to hit even shooter (player only). Projectile becomes lethal once you stop touching it for first time.
