[Not a bug] Polyobjects and bridge things

The Ultimate DooMer · Mon Jan 19, 2004 11:18 am

Polyobjects stop dead when they run into bridge things. This may seem logical when this is below the fake floor (as bridge things have a thickness), but they stop in front of bridge things that are not sticking up above the fake floor as well. (ie. an 8-unit-thick bridge thing placed 8 units below the fake floor)

Makes sense to me. All polyobjects are infinitely tall.

The polyobj spans the full height of the geometry, including what's under your fake floor. If the object didn't stop, and kept moving above your fake floor, you'd also find it underneath it as well.

The thing is that the poly isn't long enough to actually reach the edge of the fake floor.

How about an example WAD?

No need,as I've fixed it.

So it sounds like the polyobj was getting stopped a few feet away from the edge because the radius of the bridge thing extended a ways into the solid surface the polyobj was positioned on... Or was it something completely different?

The radius was larger than the amount of room it had, but the height of it was the same as the floor (so it wasn't sticking up above the floor) and in any case I thought that old bridge bug had been fixed (so bridges could now run into each other and walls without causing any trouble).

Well a polyobject isn't a wall persay, and in any event any moving surface by default can be obstructed by things. Since a bridge object IS a thing, it's only natural that the polyobject gets blocked by it. The thing you have to remember is that a polyobject is infinitely tall, so even though the bridge is at or below the height of the floor, that doesn't matter. As far as the bounds checking is concerned, the Z position isn't even a factor.
