It's not exactly clear what you want. How many times do you want the shotgun to be able to fire before you have to reload it? Do you want the shotgun to stop working when it's empty until the player presses a different key to reload it? Should the reload start automatically when the shotgun is empty, and only be manual if it is partially depleted?

EDIT: Anyway, I coded a manual reload shotgun for DukePlus, and I think AMC TC has several like that. It will be hard for you to find the relevant code by searching through the CONs, but I don't have time to write new code.

I want the shotgun to reload after firing 8 rounds. I want the shotgun to stop working after it empties all 8 rounds, until i press the reload key. You don't have to write a new code, I will find it in the AMC TC or DukePlus, and make it work, somehow. Thank you for telling me, and also for help and patience with me.

I invented air bubbles that Duke can pick up underwater. I wish I could make sure that the counter of the airleft value was stopped for a short time, before health declined again. When Duke picks medkits out of the water without problems, I would like to do the same underwater.

Can anyone shed some light on how different blending modes are implemented in eduke32? For instance transparent lights and lens flares that have an 'additive' property instead of just a straight transparency? I can only find info on fogpals on the eduke wiki. Thanks

Hello!
Is there a way to determine which frame of the animation is currently playing? This is necessary, for example, to synchronize the sound of steps with character animation. Or to make sure that the animation has finished playing.

ifactioncount and resetactioncount can be used to do what you want.

For my part, I planned different kinds of armor with well defined values. I wish I could make sure that the armor that is picked up only affects Duke's health when it reaches 100%.

For example a golden armor of 200hp, will keep the health always at 100%, until the armor runs out.

Last thing, I would also like to make sure that Duke cannot pick up another armor, until the special armor is used up below 100%.

[Mr. Alias Nameless]

is there any way to read keystrokes in events EVENT_DISPLAYMENU, EVENT_CHANGEMENU, EVENT_SCREEN or when game is paused setuserdef[] .pause_on 2
This could be very useful for creating an inventory interface, for example.

Is it possible to detect if the player has a given tilenumber in view? The way I was thinking of doing it was to do a hitscan check from every pixel covering the player's view, but that sounds entirely ridiculous.
Still, we have some functions like ifcansee that work against actors. I probably need that but for textures.


edit:

Apparently this is exposed via the gotpic array in CON.

ife gotpic[tilenum] 1 => means that tilenum is currently visible

The array doesn't reset on its own (there is an EVENT_RESETGOTPICS but from what I can tell from the source code, this only gets called when handling mirrors), but you can do so manually inside your code bock:

setarray gotpic[tilenum] 0

So far performance seems ok

Interesting. So what exactly causes the elements to get set? For example, if a certain enemy dies in a place where no players are around, is its dead body tile "in view"? Or does it require that the tile is actually rendered on a screen?

[Sangman]

Good questions, which I'm sure somebody can answer

[F!re-Fly]

I just had another rather specific idea. I wonder if it really possible that an enemy can patrol freely in an area until he sees the player, in order to attack him? I wonder if modifying a statnum or using a sprite similar to "locator" could do that, to define a route in a sector.

It requires the tile to be rendered.

This was added so the skybox in Ion Fury would only be drawn if the skybox texture (which is a blank tile) was visible.

Note that it's only set after it's rendered (meaning that in the Ion Fury example there's a 1 frame delay).

I miss-clicked and downvoted you by accident (that was supposed to be an upvote).

Anyway, that's a good feature for saving resources with an expensive command like showview

I want to make an actor shoot at, not another actor, but at a specific spot. I have the X/Y coords of both shooter/target, but I don't know how to measure the distance between two spots. There's ldist but it's only useful with sprites, is there an equivalent for points?

[Darkus]

Found a solution. It's a bit messy, but it consists of teleporting the player, take measurement, and teleport it back.

getplayer[THISACTOR].posx temp1
getplayer[THISACTOR].posy temp2
setplayer[THISACTOR].posx XPOS
setplayer[THISACTOR].posy YPOS
ldist DISTDIFF THISACTOR player[THISACTOR].i
setplayer[THISACTOR].posx temp1
setplayer[THISACTOR].posy temp2

I'm trying to make monsters shoot at the direction of the player's movements (if you played Unreal games, you know what I mean).

[Danukem]

Seems legit for a Duke hack. I've done stuff like that. But you could have used the Pythagorean theorem and just calculated it.

EDIT: Here, if the vars "hitx" and "hity" are the distant coordinates, and assuming the other vars have been declared, then this will do the job

	set xydist sprite[].x
	sub xydist hitx
	mul xydist xydist
	set y2 sprite[].y
	sub y2 hity
	mul y2 y2
	add xydist y2
	sqrt xydist xydist

[Darkus]

Thanks, it's the example I needed. It works in both cases, I managed to achieve the effect I wanted: making enemies anticipate your moves.

Example, dodging left:



Also made a variant that take account of height. This time dodging left and jetpack on, going up:

[Danukem]

Cool. The old move parameter "faceplayersmart" also does that, although I'm sure it's very primitive.

[Darkus]

faceplayersmart don't take account of the distance and projectile speed. Just run toward an enemy that using that move, and I see how he turns you back

[Jblade]

Some time ago somebody (I'm fairly certain it was Fox) posted some script showing how to use totalclock or something like that to do smooth 60fps weapon swapping animations. Anybody know what I'm talking about and still have it around?

Hey guys, is there a way to cut/mask wall aligned sprites (like blood decals) through con? like cut off or even wrap around the sprite as soon as the wall ends?

Not sure what you mean. At first I thought you meant prevent them from hanging off of ledges, but now I doubt that.

There is hardcoding in the base game which prevents the standard BLOODPOOL from hanging over ledges. So one solution is to spawn BLOODPOOL, then in a game event (EVENT_WORLD may be your best choice) cactor BLOODPOOL into your own actor, and change size and pal if needed. Since BLOODPOOL is already in a verified good location, that should be fine (although it won't be if your sprite is much bigger).

If you want to use your own code then I would suggest a loop where you test out some nearby coordinates (nothing fancy, just add and subtract values to your sprites's x and y) and check to see if the floor height is the same if the tested coords are in a different sector. Also you can check for slopes. If checks indicate a bad situation, you can resize or delete your sprite as appropriate.

I have player weapons not flashing the screen during firing but haven't been able to do the same for the enemies. I didn't find anything with a quick browse thru the wiki. I'm using Polymer in case it makes a difference.

Maybe set PROJ_FLASH_COLOR to all 0's? Or is there a global command?

[Danukem]

What exactly are the enemies shooting that is making the screen flash?

[Mark]

pistol, shotgun, chaingun ( machine gun ) They are already custom coded from previous owner of the project. This might complicate your answer. I was hoping for a simple global command or similar.

[Danukem]

I can't tell from your description whether there are polymer lights being spawned when the projectiles fire, whether they are flashing the world in the old-fashioned way (setting global visibility for a moment), or whether they have been specially coded to literally flash the screen (via palfrom or equivalent).

The flash color thing might work if they are polymer lights.
