How Do I Shot Web?

[xtkaythen]

If web was a door, and the shot was granted exclusive rights to -- you know what?

It's really late where I am, and I have a final due in the morning, so I'm gonna go work on that, and have you childish and idiotic peons work this out for me ask the helpful, lovely community take a look at this if they could:

Is there a way to detect a specific class of projectile, such as, say, a missile or a beam, to trigger a linedef, such as, say, opening a door? The thing is, it must NOT be triggered by other types of projectiles.

Basically, if somebody could get a door to open by the plasma rifle but not by the shotgun or the rocket launcher, I will mail you a post-card saying whatever you want on it.

[wiki]CheckWeapon[/wiki] ACS function might do what you want.

The only problem with CheckWeapon you might run into is if the player happens to switch weapons before the projectile connects. I managed to work around this. From Mage's Arsenal:

---

Code: Select all

// Generic Door script
// Used to make door open from only certain weapons
// For example, if you set arg2 to 3 and arg3 to 3, the only weapon that can open it is the Missile.
// arg1 is the tag of the sector. you will need to put a repeatable door close linedef on either side to make it so it doesn't stay open
// Common args combinations:
// All weapons: arg2 0 arg3 15
// Power staff attacks: arg2 0 arg3 2
// Missile: arg2 3 arg3 3
// Wave Claw attacks: arg2 4 arg3 9
// Ice Blaster attacks: arg2 10 arg3 12
// Fire Rod attacks: arg2 13 arg3 15
// NOTE: make sure that your map has the missilesactivateimpactlines mapinfo option enabled. Otherwise, this script won't work.

#Define  Num_Classes 16

str Projectile_Classes[Num_Classes] =
{
"PowerBolt","ChargedPowerBolt","SuperMissile","MAMissile",
"WaveBoltTopLeft","WaveBoltTopRight","WaveBoltBottomLeft",
"WaveBoltBottomRight","ChargedWaveBolt","WaveBuster","IceBolt",
"ChargedIceBolt","IceSpreader","FireBolt","ChargedFireBolt","Flame_Thrower"
};

Script "MA_DoorOpen" (int arg1, int arg2, int arg3)
{
    for (int i=arg2; i<=arg3; i++)
    {
        if (CheckActorClass(0, Projectile_Classes[i]))
        {
        Door_Open(arg1, 128);
        }
    }
}

There are 2 problems with the above code though. You must have "missilesactivateimpactlines" enabled and I haven't tested it with hitscan attacks (you might be able to do it with the bulletpuff?).

Would it also be a problem if something else (e.g. an enemy) had a stray shot that hit the web while the player just happened to have the correct weapon readied or does CheckWeapon only check the script activator's inventory?

According the source code, there's a check for non-player actors:

Code: Select all

        case PCD_CHECKWEAPON:
            if (activator == NULL || activator->player == NULL || // Non-players do not have weapons
                activator->player->ReadyWeapon == NULL)
            {
                STACK(1) = 0;
            }
            else
            {
				STACK(1) = activator->player->ReadyWeapon->GetClass()->TypeName == FName(FBehavior::StaticLookupString (STACK(1)), true);
            }
            break;

Here's my [censored word] solution that doesn't work:

---

Give the player a dummy item at the start of the projectile fire(travel) sequence, and remove it upon projectile death. ACS activation line checks for inventory and opens up if checked correctly. For hitscan weapons, give the dummy item on raise, and remove it on deselect. If the ACS checks that the user has both the projectile/hitscan one, it will open (assume weapon switch), but if it has just the hitscan ones, then it doesn't work. Idk if you want to collect 600 dummy inventory items though.

I just googled your project and this is pretty much EXACTLY what I am going to do xD. The concept for Metroid Prime is the way that Heretic was presented to me. I was dissapointed, and now I want to make a wad to show what I thought Heretic would be.

I'm thinking about making a script that works with HateTarget and manually open the door that way. What do you think? this could only be made more useful by
a.)
not having the bullet target IN the actual doorway or
b.)
somehow making

The setup:

---

in decorate, create a thing called rocket target. give it a pain chance of 0. give it a pain chance from rocked tamage (typo too funny to fix) of 255. on pain chance, A_ACSExecuteWithResult. create five sectors. 256 square, 256 square, 64 square, 8 square, 8 square. each room has access to a door and then a tiny shelf that has a rocket target in it. now, the reason i'm not testing this manually, is because it SHOULD work. my question is, how inneffective is this? is there a better method of doing this type of setup? and is there a way to do this without ending up with a billion tags i have to remember?
