I got three questions I'd love to know how.
How to modify weapon stats? Like how fast it shoots, what art it loads and etc. For example, changing Devastator's firing speed to be much slower and also its rockets to make them bigger.

How can I fully copy of an enemy but with different skin? I'd like to have fully copy ALIZ for example. I got two soldiers one is male and other is female.

How do I remove intro video? Is there way to just add con code or do I just need 1 millisecond long video replacement?

[Daedolon]

For the weapon functionality, check the weaponx variables over at Category:Pre-defined_gamevars

Then when you're ready to edit the actual stuff the weapons emit, check Defineprojectile.

For skipping the intro video, check the LOGO_FLAGS. It defaults to 255, so if you want to remove, say the LOGO_DUKENUKEM, you remove 32 from the value.

So how I would type it?

gamevar LOGO_DUKENUKEM 0 0

?
Not good with CON coding.

[NightFright]

I am using this in the addon compilation as well. I disable all cutscenes with gamevar LOGO_FLAGS 2095359 0.
If you want to deactivate LOGO_DUKENUKEM which has a value of 32, you deduct that from 255 and use it like this: gamevar LOGO_FLAGS 223 0.

Following the wiki, all these bits are already set by default:
1 - LOGO_ENABLED
2 - LOGO_PLAYANIM
4 - LOGO_PLAYMUSIC
8 - LOGO_3DRSCREEN
16 - LOGO_TITLESCREEN
32 - LOGO_DUKENUKEM
64 - LOGO_THREEDEE
128 - LOGO_PLUTOPAKSPRITE

Add the values and you have 255. That's the default. If you go above that, e.g. in order to put LOGO_SHAREWARESCREENS (256), it is 256+255, so: gamevar LOGO_FLAGS 511 0. You can combine modifications, then you have to add more values. For example, if you don't want the ep.1 and ep.2 cutscenes to show, you use these:

4096 - LOGO_NOE1BONUSSCENE
8192 - LOGO_NOE2BONUSSCENE

Adding them is 12288, so 12288+255 = 12543. Result: gamevar LOGO_FLAGS 12543 0.

Bottom line is: Add conditions by adding values, remove them by subtracting values. It's a bit tricky with the "NO" entries (LOGO_NOE1BONUSSCENE, LOGO_NODUKETEAMTEXT etc) since in those cases you have to add values to remove something, but you get the hang of it quickly. Please correct me if I am wrong here.

[Daedolon]

For some quick profit, just set the variable to 5 0.

[Jenz/Amaka]

Um, I must be missing something. I tried adding...

gamevar LOGO_FLAGS 2095359 0

in GAME.CON and my own custom .CON to disable all cutscenes but nothing. They all still show up.
Then I tried

gamevar LOGO_FLAGS 223 0

to disable Duke Nukem text appearing but it still shows up.
So then..

gamevar LOGO_FLAGS 251 0

to disable menu music but that didn't work either. What did I miss?

Oh ffs. Nevermind. It's working exactly as it should. Thanks guys. I forked up.

Three kinda related questions.

Firstly I want to create an equivalent of a sector effector to perform various custom trickery. The issue will be if I implement this as a useractor then it's actor code may not run because it is sleeping (statnum = zombie). So, is there a way of making a never-sleeps useractor ?

I notice there are events 'EVENT_GAME' or 'EVENT PREGAME' which fire for each actor per game tic, but it is not clear whether these will still run for zombie actors. If there was an EVENT_TIC (which there isn't) then I guess I could use it to force my custom sprite's statnum back to 1 (awake) and I might be able to infer my hypothetical EVENT_TIC using some logic in EVENT_GAME, but this is all sounding rather wasteful of CPU cycles as well as messy.

Or .. is there another better way to implement this?

Secondly, as part of said trickery, how do I detect when a 'channel' fires (e.g. from switch, touchplate, etc) ? It would be jolly useful if there was a game event that signalled this but I can't see one. For switches I could iterate through all sprites (or a subset based on statnum) looking for appropriately tagged switches and get their state from picnum but that feels like it could add a lot of processor overhead if I did it on every game tic.

Finally it would be nice if my custom sector effector would allow me to utilise the lotag for my own purposes but currently if this is non-zero then my custom sector effector is deleted in game, presumably 'cos the lotag is being interpretted as multiplayer only or something (or is it skill level ? I forget). Whatever is there a way around this behaviour?

[Edit] Ah-ha ! Saving the lotag in a gamevar during eventloadactor and then setting lotag 0 fixes that last issue.

TTFN,
Jon

[December Man]

It's me again. Is there as a way to disable the pistol casing and shotgun shell sprites ejecting without editing tiles art files? Just with pure con editing? I added casings that drop on the floor as projectiles etc. but now you have these projectiles and the old casings.

Managed to create full copy of Lizman but I got few problems.
First is that Lizman's Copy size ingame is huge. I know that I gotta put this code, but I don't know where.

{
      sizeat 42 40
	  cstator 257
}

And also them Lizman's copies seem to attack immediately even when the player is not seen.

[Daedolon]

Anywhere after (user)actor. Preferably at the top.

[Mark]

Check for lines containing "ifcansee" or "ifcanseetarget" and see if there is something there that needs tweaking. If there are no lines with those commands then you will need to add some. I don't know if you have done this or not, but I recommend looking through other people's custom con files from mods and TCs to get an idea how some things work. That helped me a lot.

That's because some enemies are hard-coded. In other words, part of the code is written directly in the executable.

Add this somewhere in the CON (obviously not using the LIZMAN tile):

appendevent EVENT_LOADACTOR
  switch sprite[THISACTOR].picnum
  case LIZMAN
  case LIZMANSTAYPUT
  case LIZMANSPITTING
  case LIZMANJUMP
    sizeat 40 40
    clipdist 80
    cstator 257
  break
  endswitch
endevent

Find these parts:

actor LIZMANSTAYPUT LIZSTRENGTH ai AILIZGETENEMY cactor LIZMAN enda

actor LIZMANSPITTING LIZSTRENGTH ai AILIZSPIT cactor LIZMAN enda

actor LIZMANJUMP LIZSTRENGTH ai AILIZJUMPENEMY cactor LIZMAN enda

actor LIZMAN LIZSTRENGTH

Replace with:

useractor enemy LIZMANSTAYPUT LIZSTRENGTH ai AILIZGETENEMY cactor LIZMAN enda

useractor enemy LIZMANSPITTING LIZSTRENGTH ai AILIZSPIT cactor LIZMAN enda

useractor enemy LIZMANJUMP LIZSTRENGTH ai AILIZJUMPENEMY cactor LIZMAN enda

useractor enemy LIZMAN LIZSTRENGTH

I'm intending to respawn enimies from within a CON script (and the standard RESPAWN sprite 'aint gonna cut it). Whilst I can spawn stuff easilly, how do I update the total enemy count ? If the player hasn't killed a monster I have, or intended to have, spawned then it needs to be added to the number of missed kills.

Also, if I may, a repeat of previous question - how do I detect an activator firing from within CON code ? Possible ? Not possible ?

I'm not entirely sure what you are asking, but you might be saying that when you spawn an enemy, the max number of kills in the map does not get increased. If that's the case, then you can fix that by reading/writing the following:

I couldn't see how to use checkactivatormotion. At the moment I've implemented what you have done, my own activator system and grouping sprites as a chains of groups of sprites (debugging a linked list of linked lists in a primitive script language and no debugging tools nearly did for what little is left of my sanity!). Unfortunately it does mean I need helper sectors (e.g. a door) to translate a standard activator to jonz system, which is a nuiscence.

Can you provide any further info on the contexts in which Checkactivatormotion works ?

Currently my main game loop looks like this:

gamevar ticky 0 0
gamevar startupdebug 1 0

// Called once per "tic" _per_ _actor_. Not clear if this gets called for actors that the
//   game has decided are temporarily zombied ? Jonz sprites are not useractors so maybe
//   will never be zombied ??
onevent EVENT_GAME

	ifvarn startupdebug 0
	{
		... dump some debug stuff
		setvar startupdebug 0
	}
	
	// Fudge: There is no event that runs once per tick so we need to infer one.
	// Ticks are roughly in milliseconds. This is NOT accurate for multiplayer
	//   and game should never sync to this for multiplayer. TODO: Use what else?
	getticks temp1
	setvarvar temp2 temp1
	
	subvarvar temp2 ticky
	
	ifvarg temp2 33	// Roughly 30 times per second. Ish. 
	{
		setvarvar ticky temp1
		
		// Process jonz main sprite system
		//   This is more efficient this way otherwise I'd be searching chains of
		//   groups of sprites for every actor on every tick. What I need is an EVENT_GAME
		//    that runs once per game tic but there isn't one ?
		state process_allsectormonitors
		
		state update_sectorchangers

                //state move_sprite_groups   TODO
		
		// TODO : revise this if how sounds are played is influenced by THISACTOR
		state update_jsounds
	}
	
	// These effects may spawn objects so will only work if THISACTOR is correctly set.
	state update_alljeffects
	
	state update_alljrespawns

endevent

It has happened this way because I'm not confident about when, or what happens, should my sprites get marked by Eduke as zombied because the player hasn't seen them in a while (however they are _not_ useractors). Also unless I've missed something there is no event that fires once per game tick - plus I dont know the interval of a game tick.

Yes, it will re-interpret THISACTOR. If you use it for getactor, THISACTOR returns the current actor ID, for getplayer it will be the nearest player ID, and for getsector it will be the current actor sector ID.

It's tricky, but in multiplayer you would have to change the value of max_actors_killed for all players...

Not sure where you are getting with this. First of all, EVENT_GAME runs every tic for all existing sprites in the map, including sleeping (zombie) actors. So a global gamevar would be overwritten.

If you want to prevent an actor from ever sleeping, I believe this would work:

onevent EVENT_GAME
  ifactor MYACTOR
    setactor[THISACTOR].httimetosleep 0
endevent

I did enquire about how to achieve what I'm trying to do in previous threads when I was at the planning stage, this so far has been the only way I've been able to move forward.

I have sprites grouped into functional groups as sprites within a group interact with each other, with one sprite within that group acting as a master. When I wrote that piece of code you need to bear in mind that I couldn't get an answer on whether EVENT_GAME would still get called for sleeping sprites so this was the only way I could see to absolutely gaurentee my sprites would get processed. A gaurentee that EVENT_GAME is _always_ called for every sprite will certainly make my life easier.

If a RESPAWN has never respawned during a game then that should be counted as one enemy the player failed to kill. After the first respawn, it does _not_ count as a missed enemy unless it has actually spawned another enemy. I doubt that logic is built into the game.

These pages are redundant. In a website running on a wiki software you define categories for pages, which serve merely for an organizational purpose. However EDukeWiki has its own page for structures, which are preferable.

These structures exist for all sorts of sprites.

Ah-ha, so the mysterious MULTIMODE is in fact the number of players. (Does a bit more delving) should that be numplayers as that doesn't include bot players? (for the original purposes of kill count I doubt it makes any difference, but I'm thinking more generally).

Do you mean unsynchronised between multiple players ? Or something worse ?

The reason I'm using my "ifsoundvar" is only to enable playing one sound effect after another finishes (I've given up doing this with door sectors as duke's door-generated sounds are bloody unpredictable at best), or loop a sound (save building elevator help sectors - that really was a neat trick). I'm not using the end of a sound to do anything more than that so should I get away with it ?

If my object spawns a sound - 71, say - and whilst that is playing some other game event also starts a sound 71 then yes my object will be waiting for the second one to finish, but that is a minor limitation of my system. In practice the sounds spawned by my object are likely to not crop up at the same time elsewhere.

Jblade, on 03 October 2015 - 02:50 AM, said:

By accident yes. (Indeed, 75% of errors I make are 'cos I forget the additioanl 'var' on the end of funcs).

There is 'sound' for playing a fixed sound, 'soundvar' for sounds based on a variable, 'ifsound' to check for a fixed sound and .... (drum roll) ... no fricken 'ifsoundvar'

How about just creating your own custom sounds instead of complicated code or Build tricks to play one sound after another, etc...

Because I'm creating a re-usable library - think extended/improved version of sector effectors and such. The sound system is also a lot more than only stitching sounds together.

I agree if I were only working on a specific map then, yes, simply whip out CoolEdit Pro or Audacity and stitch the necessary sounds together, job done.

Ok. I didn't realise your goal was creating something for everyone. Your doin' great, carry on.

The Mechanic, on 03 October 2015 - 04:57 AM, said:

Yeah. It's okay to use ifsound to check if a sound should be played. But, for example, sounds are never played if you have sounds off in the menu, so anything that affects the game would break the sync in multiplayer.
