What's sector effector 12? (I don't know the numbers by heart)

It's a light switch SE, which switch-on light on the sector when push at button, and swicth-off if shot at lighter or push to off the button

Right, I want to ask something, though I'm not sure whether this is the right thread for it - but I don't want to start a whole new thread. Ok here goes.
Some time ago on 3D Realms forums, I came up with an idea for a mod/tc that was basically Duke Nukem 2 style in Duke Nukem 3D, I did a bit of work and then kind of forgot about it, but I keep thinking of starting it up again, there's only one thing that stops me - CON Code, i can't really seem to get back into that, I've been slowly moving away from programming for a couple of years now, and CON code just doesn't seem to be something that will go back into my head (And I think it's a bit different if i want to take advantages of the EDuke32 features anyway) so, If I did decide to start the mod again, would someone perhaps give me a hand with that? I would literally be doing everything else for it except the CON Coding, well, might decide i needed a few models, but more likely I would use Sprites, as it would be like a 3D SideScroller (DNMP Style).

This isn't something I am definitely going to do mind, but I am really thinking about it for when I have my Music Packs finished as I would have no more foreseeable projects lined up.

[Danukem]

Speaking for myself, I would never sign on to code a TC unless the person I was working with had a proven record of finishing and releasing stuff. Pretty much every modder in the community who has been around long enough has been burned at one time or another by putting a lot of effort into something only to have it wasted because the other member(s) of the team didn't do their part.

[High Treason]

And I don't blame people for thinking like that - I would do the same, that sort of thing used to happen to me all the time with other kinds of projects (usually at college, I still blame the rest of my group for me failing that IT course ).

Which gives me an idea, what I think I will do, if I decide to do this TC/Mod, I will do everything I can with it (Maps, Graphics etc...), would probably even have a crack at the CON code myself as well as I could probably get some of it working, and then when I have everything but the code I would need, then come back and make a thread saying that I basically have everything done, I just needed some code before adding the finishing touches (the finishing touches being stuff in the maps that relied on the code) - yeah, I am now thinking that is a better idea.

How can I get the distance of an actor to the midpoint of a wall it is hitscanning ? I've tried numerous attempts and this one was the closest I could get, yet it doesn't work quite well.

			getwall[hitwall].x x
			getwall[hitwall].y y
			getwall[hitwall].point2 point2
			getwall[point2].x wx
			getwall[point2].y wy
			getplayer[THISACTOR].posx posx
			getplayer[THISACTOR].posy posy
			
			addvarvar x wx addvarvar y wy divvar x 2 divvar y 2
			mulvarvar x x mulvarvar y y addvarvar x y sqrt x x
		   
			mulvarvar posx posx mulvarvar posy posy
			addvarvar posx posy sqrt posx posx
			subvarvar x posx

[Lord Misfit]

Lucky for you I've done this for NR with using ATMs/Cola Machines/etc. Since all walls are straight lines, the method below should always work. However you'll have to change the varnames to your own since these are taken straight from NR's code.

 getwall[hitwall].x hitwallx
 getwall[hitwall].y hitwally
 getwall[hitwall].point2 hitwallpoint2
 getwall[hitwallpoint2].x hitwallpoint2x
 getwall[hitwallpoint2].y hitwallpoint2y
 setvarvar hitwallcenterx hitwallx
 addvarvar hitwallcenterx hitwallpoint2x
 divvar hitwallcenterx 2
 setvarvar hitwallcentery hitwally
 addvarvar hitwallcentery hitwallpoint2y
 divvar hitwallcentery 2

 getplayer[THISACTOR].posx posx
 getplayer[THISACTOR].posy posy

 setvarvar wallxdist hitwallcenterx
 subvarvar wallxdist posx
 setvarvar wallydist hitwallcentery
 subvarvar wallydist posy

And if you want to check your distance from the wall with this method, like for the way I mentioned above, you can use this form of example to help you. This example is for if you're within "item grabbing range" of the wall.

 ifvarg wallxdist -845 ifvarl wallxdist 845
{
  ifvarg wallydist -845 ifvarl wallydist 845
  {
   // do something
  }
}

Let me know if that helps. >.>

This is what I've done, I removed those "setvvarvar" stuff because I thought they were unnecessary (I tried it the way you have given, "exactly" the way you've given after this one failed) however they both don't work. The values they return are with 5 digits...

Quote

CONLOGVAR: L=8054 x (Global) =87965
CONLOGVAR: L=8054 y (Global) =92763

This is when I'm at point blank range to the wall. Also, I needed the code to work with diagonal walls too, then I thought I could use phythagoras, but my tries proved my code doesn't do so well.

[Danukem]

Averaging wall point coordinates to find center: WIN!

Subtracting center coords from player coords to find distance to player: FAIL!

Yes, it is simpler computationally to use subtraction, but the result is not very accurate, so just use the Pythagorean theorem and do it correctly.

Which I have no idea how to do........not that I need it. I once required sometihng like this for making my actor's climb walls correctly but I just had my actor check his angle to both wall points to see if he was within the wall and not just clipping it. It was also used to allow my actor to align correctly since he needed to know whether to add or subtract 512 of the walls angle (so he would end up flat against the wall)
My method is probably (most certainly) lame so I wont bother posting exactly what I did.

[High Treason]

Right, I am not asking for help as such, because that would be plain cheek - and it could end up wasting peoples time as well, and that probably wouldn't go down very well - I just want to know whether certain things can actually be done.

As I am now working on this mod of mine, i must ask whether it is actually possible to change the camera angle for third-person view using CON code?

I just want to know before I pour weeks/months into this project. Failing that, I guess it could work if it were instead possible to change the angle the gun fired at, but I also am not sure that is possible.

[Danukem]

Yes, it's possible, and it's not even the most difficult thing you'll need to code.

[Jimmy]

The Pythagorean theorem is 10th Grade Geometry. I nearly failed Geometry and I could tell you it:
A^2 + B^2 = C^2

[XThX2]

My problem was not with the theory, in fact, I believe I've applied it perfectly, yet it refuses to work. The one I'm using is, for distance between two points, which is similar.

Quote

sqrt[(x_1 - x_2)^2 + (y_1 - y_2)^2] = Distance

If you believe that you are applying it perfectly and it's not working, then you must think there is something wrong with EDuke32 that is preventing it from working. But if you really believed that, then surely you would have posted your perfect code to make your point.

[XThX2]

			divvar x 2
			divvar y 2
			
			subvarvar x posx mulvarvar x x 
			subvarvar y posy mulvarvar y y
			addvarvar x y sqrt x x
			addlogvar x

Well, the values don't match at different places, which I'm sure it's because of the usage of "coordinates" I can't think of a better way to make it.

That looks right! I have used code that does exactly the same thing and it has worked fine for me. It makes me wonder if an assumption has gone wrong farther back, like maybe you aren't using the right wall points.

[XThX2]

Damn you're right ! I was hitscanning the wall "hitwall2" but I was using "hitwall" all the time !!! I hate when this happens, and this is not once or twice that I kept bothering you and others because of it ;( It works perfectly fine now :/

Isn't there a command that plays the quote from a gamevar?
I'm certain I've seen one but I've just been through the wiki and can't find it. I hope I haven't imagined it.

Just set the player's ftq to the quote number and set fta to the amount of time to display.

[Fox]

I would prefer to use a normal quote <id> command. Before it, just use Qstrcpy to copy of the quote you want to be displayed to the <id> one.

[m210®]

I wish to apply a method of sorting by a bubble to the code.
I have 4 vectors with different values, but the minimum value gets out only from 2 last vectors? Help me to solve a problem:)
Example:
ARRAY[1] = 3000
ARRAY[2] = 400
ARRAY[3] = 1000
ARRAY[4] = 5000
Result of a code is value equal 1000

	setvar tmp 1
	whilevarn tmp 5
	{
		setvarvar tmp2 tmp
		addvar tmp2 1
		setvarvar tmp3 tmp2
		addlogvar ARRAY[tmp]
		addlogvar ARRAY[tmp3]
		ifvarvarg ARRAY[tmp] ARRAY[tmp3] ifvarg ARRAY[tmp3] 0 setvarvar tmp5 ARRAY[tmp3]
		addlogvar tmp5
		addvar tmp 1
	}

[XThX2]

Why do you have a setvar tmp 1 at the beginning ? Remove it, instead, define your tmp as 1 X, where x is either a global, actor, player etc variable.

If it to remove, the code will cease to work and I need to receive the minimum distance every second instead of once

[Danukem]

Could someone explain in clear, plain english what the code is supposed to be doing? Is it supposed to order the array from lowest number to highest or what?

Yes, you have correctly understood. Sorry for my English.

			setarray ARRAY[tmp2] tmp4
			addvar tmp3 1

As I said, I would prefer use the normal quote and qstrcpy, I feel safer. But if you aren't going to do that, them you may check the fta_on ("Messages: on") too.

I have searched the wiki and cant find if there is a way to change the angle that the player sprite faces and the angle that the player fires at.

What do I need to tamper with to change these things? I hope they can be meddled with or else i will have to go a very long way around.

Basically what I am trying to do is make it so when the player presses the back key (onevent MOVE_BACKWARD) it changes the angle of the player sprite and firing, but it can't just change the way the player is facing because that would effectively make him walk the same way he had been doing. Obviously I am working from a 2D perspective, so he will always face the exact same angle when walking a particular way - For example, it might always set his angle so he faces the left of the map, this wouldn't matter because it is only using 2 dimensions anyway.

[XThX2]

getplayer[THISACTOR].angle angle1 addvar angle1 1024/subvar angle1 1024 setplayer[THISACTOR].angle angle1

This might work for you. Add/substract is to make him face left/right, in your case back and front (Or I assume it is.) Since the angle of player has changed, all the weapons will fire from that angle. (Unless coded otherwise)

Is that what you want? I'm confused by your post.

It sounds like you want the player to automatically turn around each time he reverses direction, like in Contra and a lot of other 2D games. That means he won't be able to run backwards, which I think is a shame, because running backwards while firing is useful. If I were coding it I would make use of the existing turn around key and allow moving backwards to function normally (albeit with an enforced corridor relative angle).

EDIT @XThX2: What do you imagine he is going to do with that code? If you are trying to help an inexperienced person by posting code, you should make sure that it actually works, otherwise it just creates more confusion.
