NOTE:[edit]
Currently in the process of a complete recode, will post once complete
Description[edit]
The Killstick is based off of a weapon used in the online comic Megatokyo.
How it works[edit]
Here's the basics: this weapon works much like the normal sniper rifle. however, when this weapon is fully charged, it consumes all ammo to create a huge explosion, simmilar to the ion cannnon. To charge the weapon you hold the trigger, pull trigger normally for normal shots
Unreal Script Code[edit]
I already have the majority of the code for this down.
General Description[edit]
This weapons combines code from at least 4 different weapons in UT2003: the zoom super shock rifle, the sniper rifle, the shield gun (charging), and the redeemer/ion cannon. I started by extending my main weapon class from zoom super shock rifle so the gun could zoom, this also allowed me to use the shock rifle beam code for the fire effect. I then started working on adding the charge function by looking at the code for the shield gun and grabbing bits of what i needed. I attempted to use the code from the shield gun for the charge effect, but things got weird (see code once it's up). I then looked at the sniper rilfe code and found what lines enabled headshots and copied those. Finally, i found the Mod_Ideas/NukeRifles here and liked how he did the spawning of a dummy projectile to get the redeemer explosion, and i did the same.

TODO[edit]
-charging effect either will not display or will spawn in the wrong location until weapon is charged <– Experiment with PlayerOffset and SmallWeaponOffset to align the effect up with the weapon
-damage adjustment for ammo on charged shot not yet implimented-
-larger beam for charged shot (is this possible?) –done, spawning larger beam now and in the right direction :D
-texturing on all meshes –started texturing, going inda slow for now

Discussion[edit]
EntropicLqd: Sounds very similar to Mod Ideas/Charging Shock Rifle
Syntax_Error: It is, except it doesn't auto charge, you must hold the trigger to charge, much like the shield gun
lemme restate the charge effect problem: when the effect initializes, it auto spawns on the weapon base, and only attaches to the weapon when it is charged... weird huh O_o
still have not had a chance to get to my own computer yet >_< it'll put the code up as soon as i get a chance
Syntax_Error: Yeay, code is up, this isnt everything, but it's a start. I'll put up individual pages as soon as i can.
Syntax_Error: Sorry for the long time away, doing taxes isnt much fun. looking for the Special DVD ed. of 2004 now, and will transfer all MOD stuff to it.
Syntax_Error: Holy #$&^ it has been a long time since i update here. Major changes to code, and most of the problems have been fixed. only annoying one left is the whole double charge/mussleflash effect (i'll get a screen up to show you) planning on putting in reload so if u have 50 ammo you can fire multiple large blasts (just not quickly ;)) also starting up the dual shotgun weapon, suggestions for alt-fire are welcome.
Foxpaw: For a shotgun weapon, there's a couple of things that come to mind for a secondary fire. Basically, shotguns are neat because there is a variety of ammunition available for them. Their lack of rifling allows for much more flexible ammunition. Anyways, although it wouldn't be entirely realistic, you could have primary fire be one type of ammo, while secondary fire was the other. For instance, one could be slugs and the other buckshot. Or one could fire "less lethal" beanbag rounds that would slow down or otherwise hinder your opponent to set up for another (more lethal) shot. Flares would be somewhat less useful. Flechette rounds are available, but would behave similar to buckshot in-game (only better!) Incendiary rounds are available, though I'm not really sure what they're for. I think smaller slug-bearing sabots may also be available.
Also you could have one fire be semi-auto and the other pump-action. Select fire shotguns have more power in pump-action mode because in semi-auto mode a significant amount of the expanding powder gases are used to cycle the weapon, leaving less to propel the projectile.
Anyways, just thought I'd toss out some ideas. A good secondary fire is essential to prevent it from being just a tracefire flak cannon.
Syntax_Error: Thanks for the suggestions, I really like the semi-auto and pump-aciton idea. That should work well with what i had planned for dual wielding: where primary fire is a powerful double shot, and alt is rapid, alternating single shots. If you only have one shotgun, primary would be pump, while alt would be the less powerful semi-auto. Would the spead change for each one? To say it another way, which type is more accurate? FYI, once I get this started I'll put up a seperate wiki page, and maybe start a page for my info.
Foxpaw: Hmm, that's a tough question. Pump action would have higher chamber pressures which would give the buckshot more momentum leaving the barrel. That might cause it to stay on course more, making it have less spread. On the other hand, the faster moving pump-action buckshot would be less stable in flight due to it's higher velocity. One of these factors would likely outweigh the other - but I don't know which one.
