EDIT: It works as intended removing the flash but it messed up the firing making those 3 weapons rapid fire like the chaingun.

Yes, for the reason I pointed out in my post immediately above yours. You used the chaingun value to set all 3 weapons.

I assumed wrongly that my code would have no effect on firing timing because gs had nothing to do with that. Live and learn.

You aren't even using gs as the engine gun shade variable. You may as well replace it with a temp var. You are just storing the weapon flag value there then orvaring it. You should do the orvar once per weapon.

Hello everybody,

I suppose it's the right thread to post that question, so is there any way to control an animated 3d model with the 'use' key ?
What I mean is a 3d model which starts its animation forward or backward each time the player presses the "use" key when looking at it : for example an animated switch, a valve wheel or a door.

Does anyone think it's possible - and possibly knows the way one could do that ?

Yes. I have made working door models.
1 the models work best with clip shape maps for blocking IMO
2 ifhitspace is the con command you'll want to use
3 I made two states one was advance a tile num, the other subtracted one from the picnum
4 like in defs.con define two tiles as your model states aka open/closed
5 like in game.con write code for each state of the model to switch picnum to opposite state if it detects hitspace
6 add sounds via soundonce con code

Good luck feel free to ask more or for clarification.

[Mark]

Thanks Drek. It worked but you forgot the all important first line. gamevar temp 0 0. Luckily I knew just enough about cons to add that in.

That's great, thanks. In fact I have never made a script and I didn't know how to begin.

Well I'm not very skilled in coding.
I'm wondering how the door is animated when it's closing.
And also why there is a counter to 32.

[Kyanos]

It just slammed shut. It was wip.

The count is in there to prevent a glitch where the door would open and close quickly with just a quick tap of the key. The count and Boolean vars unlock the check for ifhitspace.

Otherwise is it possible to make directly rotate a sprite by 90° only with a script ?
(therefore animation frames would not even be required)

I think it is, I think it will rotate at center. Look at the top of the page for angle info.

[Zaxtor]

Found an extremely simple trick to make some sprites go "through TROR" when normally they would stop at the "top" of a TROR. I talk about TROR with no ceiling.
Normally they would just goto the ceiling of the TROR and not go up further.
For the mod I am finishing, sparks coming through the hole in the floor "somewhere" in the mod.

We know mobs, projectile will go through TROR limits that doesn't block.

first scene is it stops at the end of the TROR top and slides sideways.
second scene I added "fall" in its code and it goes beyond the TROR "top" instead of sliding sideways.
fall wont make the thing go up "fall down".
here is a test vid (not a level of my mod)

[Mark]

Is there a way to preset the x,y,or zvel in an actor's code so that when it spawns it will have that value set?

[Kyanos]

Yes a few ways and different places to do it depending on what it is you're trying to accomplish.

xvel yvel & zvel are set in mapster sometimes for custom mods, or maybe you want real velocity immediately upon map load.

Event loadactor is probably where you would set it, just setvar[THISACTOR].*vel ###

[High Treason]

espawn MYACTOR
ifvarn RETURN -1
{
  setactor[RETURN].xvel YOUR_VAR_OR_NUMBER
  // YVEL, ZVEL or whatever other structs.
}

Or else you might have to catch it in EVENT_EGS, getting the RETURN to there should be trivial, but depending on what you're trying to do, a simple ifactor might be enough if you want every actor of that type to be affected when it spawns into the map.

[Danukem]

By the way, setting xvel and zvel on an actor in the code that spawns it generally won't work, because those values don't do anything unless it is a projectile or it has been set in motion with a move command first.

[High Treason]

Well in that case, EVENT_EGS or EVENT_SPAWN are probably early enough to fix that, aren't they? I'm not sure as it's not something I've ever done, instead setting X, Y and Z co-ordinates directly, but if so the code wouldn't be that hard to implement. You'd just need your

ifmove 0 { move YOURMOVE }

in one of the events instead,

I don't know that this would make so much difference by now, though setting the VEL parameters immediately afterwards would certainly take a sprite up to full speed near enough instantly. Keep in mind that those values are in relation to the sprite's location in the map and not the orientation of the sprite - for example, rotating a sprite with a high XVEL will not change the way it moves, it will still move towards positive X on the map.

If you get stuck I'd be willing to take a quick look at what you're trying to do, as well as trying to make it work.

That's not true. Sprites with a positive xvel member will move forwards (in the direction they are facing), whether it is on the x-axis of the map or not. I think you might be confusing this with using the internal clipmove function, or the movesprite CON command, which are different.

[High Treason]

This is not at all the behaviour I have found from setting these values. However, I have only really experienced them with the player. I would have to experiment, but I suppose it isn't impossible that the player is a special case.

A cut-down version if you wish to observe this would be;

onevent EVENT_GAME
ifactor APLAYER
{
  setplayer[THISACTOR].xvel 102400 // Should be enough to make you move a little, but not fast enough to instantly smash into a wall.
}
endevent

I understand that the "ifactor" is redundant as I am using setplayer, but I use this "if" in my code because of other code that has to run exclusively in the APLAYER actor. I doubt it has any bearing at all, but it is included for consistency with what I have. Turning the player does not alter the direction in which they are traveling; A positive XVEL set this way serves to move the player towards positive X on the grid, regardless of which way they are facing.

This method is unusual for me anyway and is related to a specific purpose. Usually I just add/subtract X/Y/Z as I can safely assume the player won't be positioned outside of player space at any time the code is used.

 High Treason, on 12 May 2017 - 05:51 PM, said:

That's because the player is different. For the player, there are posxv, posyv, and poszv members, all for speeds on the different planes. So yes, the player is the one entity in the game that works as you describe -- but we weren't talking about the player. We were talking about sprites that you can spawn. For regular sprites, positive xvel makes them move forward, negative makes them move backwards, positive zvel makes them move down, negative zvel makes them move up. And the yvel member on sprites is not used for velocity -- it has different purposes for different types of sprites.

[High Treason]

Well, that saves me having to experiment with it and is interesting to know. So, the player actually is a special case then, which is actually very useful to what I'm doing, saving on a lot of math and, as you have described this behaviour, a good chunk of trial and error.

I've noticed that some interesting things can happen if an actor's YVEL is manipulated and I am aware of some effects using it to store information. One such effect I discovered is actually useful in a map I've had shelved for years.

Hi everyone,

I'm trying to create an icon (sprite) with a script behind, its role is playing a sound (determined by the lotag) when the player is close to it and hits space.
But the sprite disappears in the game (I have seen the sprite is "annihilated" in the game because of the script behind, and the sprite has not been set as invisible) and nothing works as usual...

DEF FILE :

dummytile 5970 24 24
   texture 5970 {
   pal 0 { file "fx/icon_sound.jpg" }
   }

DEFS.CON :

define I_SOUND 			5970

GAME.CON :

gamevar snd 0 2

state playsnd

    ifpdistl 1024
      ifhitspace
      {
        getactor[THISACTOR].lotag snd        
        soundoncevar snd
      }

ends

useractor notenemy I_SOUND 
  state playsnd
enda

It's painful to do a single basic CON script that works... Some modders implement within their games new effects with icons (similar to S, M, T...) like in Dark Level. But despite my effort I can't figure out how they're doing this.

May I have some help to fix it ? It would be appreciated

[Hendricks266]

Try removing "getactor[THISACTOR].lotag snd" from state playsnd and adding this to the bottom of your CON:

eventloadactor I_SOUND
    getactor[THISACTOR].lotag snd
    setactor[THISACTOR].lotag 0
enda

Basically, you need to copy the lotag into a gamevar at map load, because otherwise the engine might do something to the sprite based on the number.

That's weird, I don't understand exactly that behaviour.
But your solution works perfectly, thanks !

 David B., on 25 May 2017 - 12:12 PM, said:

It's because lotag on sprites is used to determine whether they are deleted when the map loads. If the difficulty setting is lower than the tag, they get deleted.

If you want to make sure the player has to face the icon when pressing the key you could use the ifpfacing command.

Yes I need the player faces it to make sense. Many thanks for the info, I could make it works too.

How do I add a delay to the start of an actor's action. It has the usual ifpfacing,ifpdistl,ifcansee then action. So after the first 3 conditions are met how do I insert a 1 second delay before the action starts? If it makes a difference, this actor will be performing it's action only one time in the game.

You can do it the old fashioned way:

First, define a move that will be used like a var:

move WAIT

Then, in the actor's code, you do something like this (please excuse the shit formatting):

ifmove 0
ifp pfacing
    ifpdistl 1280
        ifcansee
move WAIT

ifmove WAIT
  ifcount 30
  action MYHOTACTION

[Mark]

Thanks. I should be able to handle that. Its for the one and only souldoor I'm using in medEVIL but with my own sound byte. It starts when the player turns a corner and because of the large map, the frame rate may stutter so that the action starts before the player gets close enough for a good look at the effect. So a delay will make sure the player is close and able to see the whole thing play. I normally would adjusted the player distance to a smaller value but the distance between the corner and the door is already quite short.

[Perro Seco]

How can I make a projectile that makes different damage if shot by an enemy than if shot by the player? I've been trying to found a solution for this during months. I know I can duplicate it to have two different projectiles with two different damage amounts, but there has to be a better solution.
