For the coustom weapon can you make an option to make it use diffrent weapon models like the shotgun, pistol, or gravitygun?

Sounds lika an idea. It seems very likely, that this addon will make use of Clavus' SWEP Construction Kit for more detailed and indifferent weapon models.

In general, I'll add the gmod preset editor (known from other tools and addons) so you can easily switch between your preferred configurations.
To answer your question: If I add SCK-models to the addon, which I'll probably do, then you'll be able to change the sfw_custom's skin like any other option.

perfect cause i would like to make a railgun crossbow or a strider laser gun that uses the grav gun body. :)

i'm a sucker for defensive options. perhaps a gun that has an altfire capable of creating temporary forcefield walls?

another idea is a cannon that shoots concussive explosives that allow for self propulsion at the usual price that comes with blasting the ground under you to try to fly: your hp.

@Rukrio :
I once created a "weapon" that emits shields and was also able to palce slowly decaying forcefields. But it was so extremely buggy and stuff, that I decided not to release it yet.
But I'll give it a second look and maybe add it to the pack.

Some my ideas:
1) Alt-fire mode, which fires a grenade and it deploys a cloud of smoke on touch.
2) Proximity mines deployer. Maybe it will shoot explosive spikes, which will explode, when somebody is near (include you)
3) If you can develop a bullet penetration, you can make Railgun, which can shoot through props 'n stuff
4) Flamethrower FTW
5) Homing missile launcher?
6) Taser (lol)
7) Grappling hook mode for alt-fire

That's all for now. Hope to see thing listed above in near future.
Oh, and i forgot about presets for custom weapon designer. Add them sometime.

@OP/Darken217

the more you know, eh. as a side note a pulse rifle like UT/Quake/Doom that doesn't explode or bounce but fires slow moving projectiles would be cool. unless that pulse cannon and the shotgun you have in the mod were attempts at it in which case i suggest for an update to them you make them have a cool effect that lets you see the shots travel, like with the Trace

@Rukrio :
Most of my weapons use physical projectiles which do have travel time. The only exceptions are the Pulsar and some of the custom's weapons systems.
Tell me if I'm wrong, but you'd like to see a weapon, that does not deal aoe damage / does not use the point_hurt entity but hast travel time, right?

@Norkan :
A proximity mine sounds like a nice idea. The thing with bullet penetration or a rail gun or something is also possible... But nasty... I'll create some concepts and see how far it gets.
The thunderbolt is supposed to become a flamethrower like thing. Obviously it doesn't throw flames right now. But I'm adding more firemodes with different elements like fire, ice and poison to it.

in response i'd like to mention some of Upset's weapon packs based off Doom 3, UT, and Quake, all of which have faithful remakes of weapons in source material that do not have AOE but travel as entities. namely the Pulse Rifle in UT and the plasmagun in Doom 3, and yeah, something like that.

i'd also like to see you try you hand at something like Cave Story's Spur. it could use code like your charge sniper, or be an additional mode for it.

hhmmmmm it might be a ♥♥♥♥♥ to code but how about a way to save your coustom weapon, because creating one then reloading the wole map for it to take form getts prtty annoying after a bit.

@Trogdor :
I'm trying to add the gmod preset editor, some tools use, to the custom.

ah ok thx

How about adding a weapon that can vaporize props/enemies? Like a toolgun model that has a first fire that vaporizes enemies and small props, and a secondary fire that has to be charged for 5 seconds that fires a shot that will vaporize NPCS and larger props in a certain radius.
