That's a classic engine problem of the "teleport" elevators. It seems that basically the teleportation is as smooth as it should, spoiling the trick.

thanks for reply, so there isnt some way how to solve it? Trough CON, or maybe write my own teleport elevators...

You must change the x-y coordinates and adjust the angle of the projectile accordingly.

So I guess that means it's time to dig up the trigonometry book...

if it's any consolation, you also notice this glitch in the original game.

Would declaring these projectiles as DEVISTATOR-like (sic) do the trick? Here's what happens, from player.c:A_ShootWithZvel(), irrelevant parts omitted.

            else if (PWEAPON(0, g_player[p].ps->curr_weapon, WorksLike) == DEVISTATOR_WEAPON)
            {
                // (...)

                if (g_player[p].ps->hbomb_hold_delay)
                {
                    sprite[j].x -= sintable[sa&2047]/644;
                    sprite[j].y -= sintable[(sa+1024+512)&2047]/644;
                }
                else
                {
                    sprite[j].x += sintable[sa&2047]>>8;
                    sprite[j].y += sintable[(sa+1024+512)&2047]>>8;
                }

                // (...)
            }

The thing to note here is that the offset in the two directions is not the same even if symmetry around the center is to be achieved.

[Mikko]

Well basically it's still more RPG-like because the "hands" shoot different projectiles as opposed to the Devastator, and the firing sequences have nothing to do with one another.

[Diaz]

Is there an easy way to make a player die like he was killed by a hitscan weapon? I mean, for example, if stepping into lava (not the hardcoded lava, but one I've coded myself depending on floor texture), he doesn't explode and play the jibbed sound (which is the standard behavior for addphealth and the like).

Thanks!

EDIT: Nevermind, it looks like everything is in the APLAYER actor. Perhaps it's not even standard behavior, I've just been working with my old Fusion CONs as a base ever since I finished it...

[Mark]

I'm using flame sprite 2271 in my map in some closed in spaces. The player occasionally gets burned when walking past. I don't see anything in cons to adjust or turn off the burn. Does that mean its hard coded and I'm stuck with it?

I know I can copy and def those sprite tiles to new tile numbers and animate them. I can lose the burn, but I would also lose their flickering Polymer lights.

[Fox]

It's in the CON:

state firestate

  ifaction 0
    ifrnd 16
    {
      action FIRE_FRAMES
      cstator 128
    }

  sleeptime 300         // Never let it fall to sleep

Initially I simply changed the offset of the projectile when it's being fired (setactor[RETURN].xoffset, etc.) and, as far as I can tell, no one (of a whopping sample of two) noticed, but obviously this is just smoke and mirrors. Then I tried to change the projectile's x position based on its owner's position but this changed the entire trajectory, not merely the point of origin.

Edit: The projectiles are RPG-like.

I think changing offset is the correct thing to do, but you should change it before the projectile is fired, not afterwards.

e.g.

setprojectile[NAMEOFPROJECTILE].offset 128
shoot NAMEOFPROJECTILE
setprojectile[NAMEOFPROJECTILE].offset 0

In the example, the offset is set back to 0 after firing, in case another actor needs to use it (setprojectile changes the definition of the custom projectile).

[Mark]

Thanks again Fox. When I ran across that bit of code I wrongly assumed it was for fire that was spawned by something else in the game because of the "ifspawnedby" lines and not what I was looking for. I guess I should have changed it anyways to make sure. Shame on me.

[Fox]

The FIRE and FIRE2 actors are permanent, unless spawned by another actor which they fade away. The BURNING and BURNING2 will always fade away unless they are too far away from the player (or squished).

[Mark]

I made a breakable wood panel to be used on the floor and window openings. When I use the following code from the wiki, in game it automatically sets the sprite to view mode instead of the original floor or wall mode that is needed for these sprites. Is there a workaround for what I'm trying to do?

define WOODBREAK1 3816
useractor notenemy WOODBREAK1
cstat 257
ifhitweapon
{
sound VENT_BUST
debris SCRAP1 4
killit
}
enda

Instead of breaking code I know I can give the panels a hitag to make them disappear when hit but then there is no sound or debris.

[Fox]

Use cstator instead of cstat.

Here is a code which you could also define the hit points (where is says "WEAKEST" which equals 1)

useractor notenemy WOODBREAK1 WEAKEST
  cstator 257
  ifhitweapon
    ifdead
    {
      sound VENT_BUST
      debris SCRAP1 4
      killit
    }
enda 

[Mark]

Thanks. That weakest part should come in handy because my map will have no high powered weapons.

[Fox]

With only 1 hit point it will break with any weapon (except the Shrinker). But 10 hit points (MEDIUMSTRENGTH) would take two Pistol bullets which is not much.

[Mark]

I remember seeing something called "ifhitwasweapon" so I can specify which weapon is needed. I would like to make it breakable only with a kick.

[Fox]

useractor notenemy WOODBREAK1
  cstator 257
  strength 1
  ifhitweapon
    ifwasweapon KNEE
    {
      sound VENT_BUST
      debris SCRAP1 4
      killit
    }
enda 

[Mark]

I was looking around for what the kick was defined as. I happened to click back here and found your answer.

Cool. Duke is kickin' planks and chewing bubblegum. I'm attempting all this minor stuff now after my failures of trying to code new enemies. I needed a success to keep me sane. So next up is finding a better sound effect for the break.

[Diaz]

So I've been searching through structure members and events and can't find anything for this...

When the player jumps and lands on a sector that is lower than the previous one, besides the hard landing and view centering stuff, his movement speed will decrease for a fraction of a second. I would like to avoid that if the height difference between sectors is not very big - is that actually possible? I have already avoided the view centering, but I'm making a platform section in one of my maps where the player has to make a series of quick jumps and the movement speed reduction is annoying - makes it easy and frustrating to die.

[Danukem]

That sounds like one of those annoying little problems which has no easy solution. As a first attempt, I would try saving the players posxv and posyv into vars as he is falling, then pushing the saved values back into posxv and posyv when he hits the ground, thereby canceling the unwanted slowdown. For this purpose you could define falling as poszv having a positive value. The tic during or immediately after which poszv goes from positive to non-positive is when you apply the saved velocity values. If you want to get more sophisticated, you could apply only a portion of the saved velocities depending on how great poszv was (so that there would still be a noticeable loss of speed after a big fall).

[Diaz]

Hmmm, doesn't seem to work. Either I can't translate what you're saying into code, or the values are not what I expect due to hard coded behavior...

[Mblackwell]

What happens if you

onevent EVENT_JUMP
    setplayer[THISACTOR].poszv -2048 // or some other value
    setvar RETURN -1
endevent

This destroys any ifp pjumping code however.

[Mark]

Yet another in a long line of questions.

onevent EVENT_GETLOADTILE
setvar RETURN 7119
endevent

onevent EVENT_GETMENUTILE

I replaced the load and menu screens with my own but I can't figure out the name for the DREALMS tile 2492 so I can replace it. I tried a few variations of the word DREALMS between "GET" and "TILE" but no luck.

I'm a little confused with those links. Does this mean I don't replace the 3Drealms screen the same way I did the other 2 screens? Or should I be using those links to accomplish what I need instead of how I did it already?

That does what I want, however it has side effects:

- As you have mentioned, ifp pjumping code is destroyed, though I think I can safely replace all instances of "ifp pjumping" with a check for the player's z velocity.
- The player can now bunnyhop like crazy if keeping the jump key depressed (no idea how to fix this).
- Jumping to get out of water messes up.

So, not worth it

There is no such a thing as a event that control the 3DRealms screen. You need to replace the tile.

For example.

If necessary you can add a condition for when you're in water.

I need to make my monsters non-sinkable. When there are water where player can dive, monsters will also sink there.. I tried to find something related to that from con-codes, but with zero results. Any advice?
