Where you have

ifvarl SHOTGUNAMMO 10

you should be able to replace it with

ifvarl player[THISACTOR].ammo_amount 2 10

I've btw also managed to get rid of the out-of-sync thing - I still don't see the big difference between using a var like I do to keep track of the players current weapon and a call to currentweapon, which was what caused it..

The game already keeps track of things like ammo counts and current weapon. Attempting to circumvent this by using your own vars at best is a duplication of effort, and at worst is asking for a lot of trouble when you let them get out of sync.

Yeah, currentweapon was a mistake, it should only be used in HUD drawing events.

You're going to need to get comfortable with global scratch variables. While you're at it, take the time to indent your code correctly. (8 spaces per tab stop is unnecessary, use 4 at the max.)

He's using OldMP, which doesn't support quick structure access. Also, use SHOTGUN_WEAPON instead of the magic constant '2'.

You're basically telling me "Who cares?", which is a pet peeve when I'm trying to get across something important. Your argument is a slippery slope to completely neglecting your code style, after all, you know what it does.

This stands opposed to every commit Helix or I have made regarding "enumifying" a set of magic constants.

Furthermore, what if you want to search for all code effecting the shotgun at once? The Unix utility for this is called grep, and you'll usually see it used as a verb. You'll have much more luck grepping for SHOTGUN_WEAPON than "2".

It makes sense that you can do it like this, without declaring a new var. Regarding indentation: Yeah, it happens when I copy paste into duke4net, it's good in sublime text
If I don't use my SHOTGUNAMMO like I coded, and instead like in your code, It doesn't work - It's like it doesn't register the current ammo at all, maybe I'm missing some declaration?
- Is there a way to change the color of the crosshair together with weapon-switches?? Can't seem to find anything about it online.

This is an interesting discussion, well worth having, and I have an open mind about it. You make a good point about the search, although it's not quite as bad as you make it out to be (it would take several different searches to round up all the shotgun references, but one could certainly do a lot better than searching for "2").

I don't agree that using constants instead of defined labels necessarily leads one down a slippery slope to completely neglecting code style. Empirically that's just false. I also think that coding at the source level may require different standards. For one thing, the source code could potentially be used for a different Build game. In any case, I regard the weapon numbers differently from, say, tile numbers. I would never use "2000" in the place of "PIGCOP", and not just because of readability -- in theory you could move PIGCOP to a different tile and it would more or less work the same (although there would be some issues because there is hardcoded stuff for tile 2000 in the source!). But putting SHOTGUN_WEAPON on a slot other than 2 would require changing a lot of stuff.

[Fox]

For me labels are a huge advantage.

But there will be a difference once dynamicremap is implemented for weapons.

It's time for me to attempt to make gun-game mode. I need to make a player be limited with only one weapon which changes as the player gets or loses kills. So how do I get amount of kills of a player?

Here's your basic kill count: http://wiki.eduke32....i/Actors_killed

If you want a system where the player can lose kills, then you'll need to make your own counter.

I think I've found what I've been looking for by looking at the pages related to the one you linked, so thanks!

[thisbecasper]

getplayer[THISACTOR].frag gets the players number of frags in a multiplayer game. If you suicide your score decrements by adding one to fraggedself, because the score is the difference between "frag" and "fraggedself". Can't seem to find a structure member that is the score, so how do I make variable that is equal to score? I suppose you can't make it like this: gamevar score ("frag" - "fraggedself") 1...

[Hendricks266]

This is another example of a case where there is no need to keep your own per-player gamevar. Resist the urge to use those unless you are inventing your own quantity.

gamevar killcount 0 0
gamevar temp 0 0

state getkillcount
    getplayer[THISACTOR].frag killcount
    getplayer[THISACTOR].fraggedself temp
    subvarvar killcount temp
ends

Call state getkillcount before any code section that needs it, and it will populate the killcount variable.

I think he had come to that same conclusion, if his last post was any indication. When I posted, I had no idea he was working on a multiplayer mod, which is why I thought he might need his own counter.

This works! I have yet to understand how all of this works... Although I think im slowly understanding bits and pieces, so THANK YOU. Three more questions if I may...: How do I place a sprite or character in the dead center of the screen? Is there a way to make sure a character is drawn in the middle between the crosshair and hud regardless of aspect ratio and resolution? How do I place a quote in a specifik spot on the screen when I have the, let's say, the shotgun equipped (The quote should be displayed as long as the shotgun is equipped)? (It's only the part of being able to draw a quote to the screen that has be troubled)

[Hendricks266]

You can do those things in EVENT_DISPLAYREST using the screentext and rotatesprite. If you use rotatesprite at (160, 100) it should be right in the center.

If that sprite will be _part_ of the crosshair, I believe putting that part in EVENT_DISPLAYCROSSHAIR instead will turn it off along with the crosshair, if disabled.

I would still be interested in seeing how one manages to shoot a projectile that follows the closest player or the originally aimed at (if possible), but if you cba, it's all cool .

Something completely different:
I want to do something to the player (in this example I just set the rpg max ammo to 60), when the player kills another player actor. I thought it would work like this:

gamevar killer 0 1

actor APLAYER ...

(...)

ifdead
  {
    getplayer[THISACTOR].wackedbyactor killer
    setplayer[killer].max_ammo_amount 4 60

Buuuuuuut it doesn't...

[Hendricks266]

ifdead
{
    getplayer[THISACTOR].wackedbyactor temp
    getactor[temp].picnum temp2
    ifvare temp2 APLAYER
    {
        getactor[temp].yvel temp2
        setplayer[temp2].max_ammo_amount RPG_WEAPON 60
    }

        setplayer[temp2].max_ammo_amount RPG_WEAPON 60
    }

It works, but it was intended to increment different variables so that with each kill, your weapon got stronger or something:

ifdead
  {
    getplayer[THISACTOR].wackedbyactor killer
    getactor[killer].picnum tempkiller
    ifvare tempkiller APLAYER
    {
    	getactor[killer].yvel tempkiller
    	addvar rpgammo 10
    	setplayer[tempkiller].max_ammo_amount RPG_WEAPON rpgammo
    }

Right now I think it perfoms the "addvar rpgammo 10" many many times, because the ifdead maybe works like whiledead also? If I get a kill with this code i get 1410-something maxammo. I only want it to do once everytime a player dies. And how do I alter another players variable? Becuase in fact, I'd want to set the killers maxammo to the originally maxammo plus (the times the killer have gotten a kill) * (10)..

[Danukem]

Yeah, "ifdead" does work like while dead, so any "ifdead" condition that triggers the ammo bonus should be nested inside an "ifhitweapon" check, to insure that only the killing blow is counted. This means you should make a state that does the bonusing and call it only after appropriate "ifdead" instances.

I can see the point in making states here, although I simply can't make it to work...

state updatevalue
{
	getplayer[THISACTOR].wackedbyactor killer
    getactor[killer].picnum tempkiller
    ifvare tempkiller APLAYER
    {
    		ifhitweapon
    		{
    			addvar rpgsammo 10
    		}
    		getactor[killer].yvel tempkiller
    		setplayer[tempkiller].max_ammo_amount RPG_WEAPON rpgsammo
    }
}
ends

---

 ifdead
  {
    state updatevalue

I am drawing the rpgsammo through digitalnumberz so I can keep track of it as I'm killing players and dying to players. No matter what it wont increment, and it also just sets the maxammo to whatever the value the variable was declared with in the first place. Actually I'm doubting that I'm using ifhitweapon correct, because when I place the two lines below into the if-statement together with "addvar rpgsammo 10", it wont even set maxammoamount

[Hendricks266]

The ifhitweapon/ifdead structure should look like this:

state updatevalue
    getplayer[THISACTOR].wackedbyactor killer
    getactor[killer].picnum tempkiller
    ifvare tempkiller APLAYER
    {
                addvar rpgsammo 10
                getactor[killer].yvel tempkiller
                setplayer[tempkiller].max_ammo_amount RPG_WEAPON rpgsammo
    }
ends

ifhitweapon
{
  ifdead
  {
    state updatevalue

If this doesn't work, there may be something that prevents setting max_ammo_amount from working, and in thta case I'll look into it.
