UDMF vertex slopes

[DavidPH]

Adds UDMF properties to vertexes for applying vertex slopes to them directly, instead of via things.

Code: Select all

vertex
{
	zceiling = <float>; // Heights are absolute. Default is no slope.
	zfloor   = <float>; // Note that undefined is not the same as 0.
}

EDIT: Rewrote so that the slope data is in an external struct. An array is created when loading a UDMF map and deleted after reading the slope values. (For non-UDMF maps, the array is NULLed and the length set to 0.)

I like this, I like this a lot.

That's 2 mappers who use vertex slopes and like this. I SEE A TREND!

10/10.

I might actually find myself using vertex slopes now. For some reason I've never felt like littering a map with extra things so I've generally stuck to the "Vaderslope" method instead.

This has my vote as well.

The idea is good but the implementation is not. This increases the size of the vertex structure from 8 to 20 bytes but those 12 bytes are never ever used anymore after setup. Before this is added it needs to be changed to store the temporary data in a temporary data structure.

[DavidPH]

OK. I wasn't sure if it'd be a problem or not. I'll go fix that, then.

New patch is done. I wasn't certain what else to do with the vertexdata array, so I delete it after loading slopes. This didn't cause any problems when I tested, but if there's a better place to do so (if it should be done at all), then feel free to move it (or tell me where to move it to).
