Are floor decals possible?

[steelbread]

Is it possible to place a decal like a blood stain on the floor within a level editor? If so than how do I achieve this?

[Gez]

No, it is not possible.

You can with a flat 3d model with a blood texture assigned to it. It is only an actor, so i will cause over hanging when places over a step or a slope.

[Gez]

Yeah, and it will not adapt to the angle of a sloped floor or ceiling...

For placing it in an editor, your best solution is to make texture variants and use sectors to apply them...

In Risen3D, models can adapt to the angle of the slope they are on (eg dropped weapons will align themselves to the angle of a sloped floor if they fall on to one (though with weapon models rotating, this can sometimes look a bit odd - though better than if they rotated into and out of the floor had they not aligned to the slope)).

Anyway, I wondered if anyone felt like investigating how such a feature might be added to GZdoom (probably as an actor-by-actor based flag or something would be most useful). I suspect that it won't happen, but no harm in mentioning it eh?

[Firebrand]

The slopes angle must be calculated when generating them, so this same angle could be used to set the models pitch angle and make them adapt to sloped sectors, it shouldn't be too difficult to implement IMO .

Oh if someone implements model sloping, that would be ACE! I was using models for the drivable cars in my Rise of the Dead mod, but there was no way to make cars follow slopes so it wasn't possible to construct sloped maps, otherwise it would look really ugly how a car remains flat 90 degrees even though it's on sloped terrain!

Unfortunately its not as easy as that Firebrand. The proper way to do this is similar to the way a suspension model is setup in a good driving game physics engine. In otherwords you need multiple sample points and a "floating-table". AFAIK Risen3D doesn't do this, it just derives the 3D rotation from the slope of the subsector at its center.
