[ZScript] 3D Floor info

[Major Cooke]

The struct F3DFloor could contain data like the floor/ceiling data such as the textures, the height of the floor + ceiling, along with a boolean to indicate if it really is a 3D floor or not.

Or is there another plan for this?

[Graf Zahl]

The main problem here is that F3DFloor is only referencing elements from the model sectors and ZScript is not particularly well equipped to work with such data.

[Major Cooke]

Hmmm, damn. Okay. I'll try and think of another way in the mean time.

[Graf Zahl]

What are you trying to do?

[Major Cooke]

Trying to clean up this mess.

It's a rain spawner so the idea behind this is to spawn rain above 3D floors, but not below it. And while I haven't yet implemented the code for it, to grab the 3D sector's floor texture should it be F_SKY1, should it be used in lieu of the actual ceiling.

(Ignore the failsafe stuff. That's just debug.)

Code: Select all

// Get the sector and get the ceiling texture. If it's the sky,
// start doing calculations. This should probably also consider
// if 3D ceilings have sky textures...
Sector s = Sector.PointInSector(check);

if (s)
{
    if (TexMan.GetName(s.GetTexture(s.ceiling)) ~== "F_SKY1")
    {
        double F3DHighestFloor, F3DLowestCeiling, Highest, Lowest;
        
        Highest = s.HighestCeilingAt(check);
        Lowest = s.LowestFloorAt(check);
        F3DHighestFloor = s.NextLowestFloorAt(check.x, check.y, Highest);
        F3DLowestCeiling = s.NextHighestCeilingAt(check.x, check.y, pos.z, Highest);
        // If there is no 3D floor between the player and the sky
        // Or the 3D ceiling is not high enough to block rain
        //    and the 3D floor is lower than the player's position 
        //        spawn the rain drop.
        if ((Highest <= F3DLowestCeiling) ||
            ((Highest > F3DLowestCeiling) &&
            (F3DHighestFloor <= pos.z + SpawnZ)))
        {
            double DropZ = Clamp(pos.z + SpawnZ, Lowest + 4, Highest - 4);
            Vector3 DropPos = (check.x, check.y, DropZ);
            Actor drop = Spawn("RainDrop", DropPos);
            if (drop)    
            {
                drop.vel.z = -30.0;
                failsafe = FailSafeStart;
            }
            else
            {
                failsafe--;
                i--;
            }
        }
        else
        {
            failsafe--;
            i--;
        }
    }
}

Or at least some function to return if a 3D sector is even in the XY position + Z range, the Z coordinates of the ceiling and floor along with the textures of both... or something similar.

[Graf Zahl]

F_SKY on 3D floors should be ignored as its behavior is very much undefined and will cause massive glitches.

[Major Cooke]

Right then, I'll toss out that part of the idea.

Still, something to ease getting the 3D floor between a certain range and returning both the floor and ceiling height would be fantastic.

[Graf Zahl]

I agree that needs to be accessible, but it will require a bit of an effort because the internal structure is not usable directly.
