Hey I'm hoping that someone more knowledgeable than me can help out with this, or verify that I'm on the right track.

I want to increase Duke's weapon sway speed, to match his very fast running speed. I would still like it to be tied to his velocity, but I would like the weapon sway speed to be about doubled. Unfortunately, manipulating the relevant structs (most notably player.weapon_sway) doesn't seem to do anything. It would seem that the game is hardcoded to update the weapon sway based on the player's velocity values, and while the structs aren't technically read only, writing to them is useless because they just get updated again by the hard coding before they can have any visual effect. In addition to the weapon_sway struct, I also tried manipulating certain constantly updated gamevars such as weaponx_offset in EVENT_DRAWWEAPON. That doesn't seem to do anything either, I presume because those vars aren't actually used in the hardcoded weapon display, they simply point to the underlying structs that do the work.

So, it looks like I have to negate all of the hardcoded weapon drawing and use something like the CON emulation of it that Hendricks266 supplied a while back. Then, with all of the weapon drawing under scripting control, I could replace the hardcoded weapon sway with my own. That's more work than I wanted to do, but I guess I could do it. Am I on the right track, or is there an easier way?

Unfortunately you are correct if you want more nuance. However since it's just contained in a single script it's pretty easy to get set up, You can probably be up and running in 10ish minutes.

I will note though that modifying http://wiki.eduke32....iki/Weapon_sway and http://wiki.eduke32.com/wiki/Gun_pos SHOULD be set-able.

Edit: Sorry for lots of editing, concentrating on too many other things.

I need that some non-hitscan projectiles (like FIRELASER) push switches like hitscan ones, do you have any suggestion for doing that ?

I already tried to shoot hitscan and knee-type on projectile impact, but with no result...

Strange, because I have made that hack work for me before. Importantly, it should be a player who fires the hitscan, though, since switches do not respond otherwise. One way to do this is to make the projectile cactor APLAYER, fire a short range hitscan at the exact right spot, then cactor back to its correct picnum. If you take a look at Duke Forces, search for "switchbulletcode" and you will see.

[RichardStorm]

Well i knew nothing about APLAYER thing; also, i cannot get why you shoot two bullets, but it seems to work very well ( and it never double press a button).

I tried some variations on your code, but your version is the only that works fine. Thanks

I'm currently a little bit of stuck with my CON code. About 2,5 years ago i copy/pasted a ironsight code from AMC TC and made it work. However, the ironsight works only if im holding TURNAROUND key down. I want it to be like one click will activate the iron sight and second will de-activate it, so i wont have to hold that button down all the time.

Here is the code:

onevent EVENT_DRAWWEAPON

ifvarand TEMP4 268435456  // Is the player holding the Alternate Fire key down?
ifvare player[THISACTOR].curr_weapon 3 // M4A1 Carbine Iron Sight
	{
	  setplayer[THISACTOR].runspeed 42100
	  setvar RETURN -1
	  setvar x 160
	  setvarvar WEAP_DISPLAY_TEMP2 WEAPSWAYX
	  divvar WEAP_DISPLAY_TEMP2 2
	  subvarvar x WEAP_DISPLAY_TEMP2
	  setvar y 140
	  setvarvar WEAP_DISPLAY_TEMP3 WEAPSWAYY
	  divvar WEAP_DISPLAY_TEMP3 2
	  subvarvar y WEAP_DISPLAY_TEMP3
	  setvarvar WEAP_DISPLAY_TEMP4 weapon_xoffset // setvar the weapon x sway to displaytemp4
	  divvar WEAP_DISPLAY_TEMP4 2 // divide it by 2 
	  addvarvar x WEAP_DISPLAY_TEMP4 // add it to x
	  subvar x 5 // offset it by 5
	  subvar y 40
	  setvar x 160
	  subvarvar x WEAPSWAYX
	  subvar x 10
	  addvarvar x weapon_xoffset
	  setvar y 142
	  subvarvar y WEAPSWAYY
	  rotatesprite x y 52500  0 3825 shade pal 0 0 0 xdim ydim // iron sight
		break
	}
  getplayer[THISACTOR].weapon_pos WEAP_DISPLAY_TEMP2
  mulvar WEAP_DISPLAY_TEMP2 -20
  setvar tilenum 2536
  rotatesprite x y 2536 WEAP_DISPLAY_TEMP2 tilenum shade pal 0 0 0 xdim ydim
  
  setplayer[THISACTOR].runspeed RUNNINGSPEED

endevent


TURNAROUND key has been disabled:

onevent EVENT_TURNAROUND 
setvar RETURN -1 
endevent


This one will disable the crosshair once iron sight has been activated:

onevent EVENT_DISPLAYCROSSHAIR

 ifvare player[THISACTOR].curr_weapon 3
 ifvarand TEMP4 268435456
	{
	  setvar RETURN -1
	}

I use time variables which keep for how much time a key is pressed, and the desired function is triggered or toggled when the timer is equal to 1:

gamevar  turnaround_keytime 0 1
gamevar  sight_on 0 1
...

ifvarand TEMP4  268435456
   { addvar turnaround_keytime 1 }
  else
   { setvar  turnaround_keytime 0 }

ifvare turnaround_keytime 1
   { xorvar sight_on 1 }

ifvare sight_on 1
  { /* your code here */ }
....

[Kyanos]

Where is TEMP4 being set, I don't see how this code does anything with event turnaround returning -1.

I would simplify this, make a variable ALT_FIRE = 1, set it to ALT_FIRE = ALT_FIRE * -1; if turnaround key is pressed, ezpz toggle switch, check to see if it's positive or negative then draw the proper weapon, do the proper things...

[RichardStorm]

I think TEMP4 stores input.bits ...

[Kyanos]

I'm just catching that this is based on AMC TC code which I know nothing about, cue up that simpsons gif, I'm turning around and walking away from this conversation. Good luck.

Is there a way to get the current hp of the last actor you've dealt damage to?

The code fires 2 bullets at slightly different heights. One fires from the base of the sprite and one fires a little above. The code was made for laser blasters, which are considerably larger than bullets. What would happen sometimes without the second bullet is the top half of the laser would hit the switch but it would not register as a hit. The reason it does not count as a double press is hard coding in Duke 3D. Without that hard coding, the shotgun would double press buttons whenever an even number of pellets hit.

What I do in my mods is constantly have the player hitscan and save the sprite id each tic so I know what is currently being scanned. But sometimes you are "looking at" an enemy even though it is not hitscanned (e.g. the hitscan is missing the enemy a little to the left or right). One way to address that issue is by having enemies set themselves as the looking target when the hitscan target is empty and certain conditions are met (ifcansee ifp pfacing...)

It worked! Many thanks! I have spend many hours of getting that thing worked but i didn't get it. Now it works.

Maybe a concrete example can help:

onevent EVENT_GAME
  ifp pfacing
    getactor[THISACTOR].extra actorhp
endevent

Would this show the hp of the enemy I'm looking at. Does THISACTOR refer to the sprite ID of the actor duke is facing, because it is in a pfacing branch?

[thisbecasper]

I've got the healthbar to work, kinda - so thank you!

[Zaxtor]

You know the SE Lotag 49 is Point Light and SE lotag 50 is Spotlight.
50 - makes spotlight that casts a shadow.
49 - point light (do not cast shadow)


But is there any def or con codes to make sprites act like that?
To make sprites emitting light radius like projectiles etc does.
I'm sure in projectile is hard coded.
Same for fires, atomic health etc.

The only way I know how to do it is spawn a new SE, set it up appropriately, and then link it to the actor and make it fixed to the actor's coordinates. And don't forget to make the SE go away if the sprite dies or is deleted.

An example of this is shown in a video I linked in the very first post of the EDuke32 2.0 and Polymer thread back in 2009:

[Zaxtor]

I see, kinda a customized SE-like sprite like AMC mod has?

[Danukem]

It's literally an SE that is constantly being set to the location of the sprite which you want to glow. I'm guessing that AMC uses the same idea.

[Zaxtor]

Sprite I wanna make glow doesn't move and nor die.
Is a portal.

If your mod has multiple playable characters and you want them all to have Duke's full functionality, then each character needs its own set of tiles for fists and such. I don't want Duke's fist displaying to hit the nuke button if I am using Bombshell. But, as far as I know, I can't just swap out his fist tile for a different one when Bombshell is selected. If I could just swap in a different tile (e.g. by just setting a variable for the tile in EVENT_DISPLAYFIST) that would be amazing, and that feature would come in handy (no pun intended) for many things, like stomping enemies, swiping a keycard, and more. Alas, what I end up doing is writing new display code for the other character's sprites to emulate the Duke version.

Currently I contemplate doing that for hitting the nuke button. I found this in the source for Duke:

 int const fistY       = klabs(pPlayer->look_ang) / 9;
    int const fistZoom    = clamp(65536 - (sintable[(512 + (fistInc << 6)) & 2047] << 2), 40920, 90612);
    int const fistYOffset = 194 + (sintable[((6 + fistInc) << 7) & 2047] >> 9);
    int const fistPal     = P_GetHudPal(pPlayer);
    int       wx[2]       = { windowxy1.x, windowxy2.x };

    rotatesprite((-fistInc + 222 + (fix16_to_int(g_player[screenpeek].inputBits->q16avel) >> 5)) << 16, (fistY + fistYOffset) << 16,
                 fistZoom, 0, FIST, fistShade, fistPal, 2, wx[0], windowxy1.y, wx[1], windowxy2.y);

I'm not sure how to translate that into CON code. I could eventually do it, with some learning and trial and error, but maybe there is someone around here who could do it much more easily than I. If so, I would really appreciate it!

It's late so forgive any errors, but this should be about right if I didn't fall asleep while typing (it is possible!):

It works perfectly! There was an extra backswing at first, because I forgot to include the line which caps the movement at fist_incs 32, but otherwise it worked correctly right out of the box. Thanks a million!

By the way, the following commands you used above are not listed at all in the Eduke32 wiki "full command list":

abs
clamp
inv

EDIT: There is one little thing...the avel stuff is no bueno. If you factor in input.q16avel, all that does is make the fist disappear when the player is pressing movement keys (I guess because it is throwing off the coordinates big time and causing it to draw off screen). But it works fine if the input isn't included. I wonder why the heck that is in the source.

Final code in my project ended up like this:

appendevent EVENT_DISPLAYFIST

ife pchar 1
{
	set RETURN -1
	// thanks to Mblackwell for fist CON code, adapted from Duke source
	set y player[].look_ang

I should say that I'm using the eduke old-mp build, and maybe that's why it wont run your code.

Yeah, changing the statnum to 1 in the actor code is pointless since the actor code doesn't run unless the statnum is already 1.
