A_RailAttack/A_CustomRailgun spread extension

[DavidPH]

Adds spread parameters to both functions as well as a new flag (based on this suggestion http://forum.zdoom.org/viewtopic.php?f=15&t=24722).

A_RailAttack(int damage, int spawnofs_xy = 0, int useammo = true, color color1 = "", color color2 = "", int flags = 0, float maxdiff = 0, class<Actor> pufftype = "BulletPuff", float spread_xy = 0, float spread_z = 0)
A_CustomRailgun(int damage, int spawnofs_xy = 0, color color1 = "", color color2 = "", int flags = 0, bool aim = false, float maxdiff = 0, class<Actor> pufftype = "BulletPuff", float spread_xy = 0, float spread_z = 0)

RGF_EXPLICITANGLE - Turns off spread randomization and uses them simply as offsets.

Great stuff!

Why this hasn't been added in yet... I DON'T KNOW.

Definitely a needed addition, so now we can finally make rave balls.

This guy NEED to be in developers, if he keeps like that.

This guy NEED to be in developers, if he keeps like that.

Agreed.... so does Gez probably, considering how much he's edited the ZDoom Wiki. He's probably made more contributions to it than everyone else combined. Documentation is also a very important part of development.

And, if Gez could change ZDoom..

[ZDG]

Agreed.

[Project Shadowcat]

Agreed.

postcoun... dammit.

[Major Cooke]

Bump for addition. I really could use this badly...

[ZDG]

Railgun shotgun, anyone?

[Xaser]

Ah, this is good to see.

All that's left is range and particle duration (perhaps density) to really maximize the rail functions' potential. Still, ecstatic to see that someone's finally messed with the railgun code. Haven't seen that since kgsws's ZDoom build...
