Transparent brush

[CocoT]

It's probably a noobie question but... how do you create transparent brushes in a map that will be loaded in Darkplaces?

Make it a brush entity and in a spare field declare an 'alpha' and a decimal value I'm guessing.

func_wall with "alpha" "0.x"

I included the source to my testmap in http://www.quaddicted.com/quake_engines ... spirit.zip btw.

Oh, I see
Thanks, guys!

Can you do this with models in DP?

[scar3crow]

Should be able, same field. I think DP might also support scale for models?

[MauveBib]

Yup, .alpha (0-1).

alpha 0 is forced to 1 of course, since otherwise everything would be invisible by default. -1 makes it invisible.

[ajay]

So that would be using DP_ENT_ALPHA ??
Could this be done dynamically; changing it thru' gameplay events - a monster could turn gradually invisible as it gets low on health?

[MauveBib]

Yes.

for a monster that starts with 100 health, just stick something like this in its various thinking routines:

self.alpha = self.health / 100;

Easy as cake.

[scar3crow]

In any state change you could do self.alpha whatever. This could be done by frames (an idle monster phasing in and out using their breathing frames as the instigator of the change, or being ghostly and fading in when attacking or taking damage based on those frames). DPmod has a mode (I think its skill 5 in dmm7 but I'm not for sure) which has such ghostly monsters.

You can set an alpha to any individual entity in a map, so if you want that particular ogre to be harder to spot, give him an alpha field in the editor of 0.6

But a special class of ogre, or all ogres... then yeah, just insert changes via self.alpha into his code.

Granted, I've never done any of this before =)

Dammit Mauve, I was on that like suck on a recent game - but then work got busy mid typing!

(Rubs hands in a Mr Burns style) "Excellent"

Cheers

Hey cool:


It's not always going to be an ogre, nor a bricky box room (indeed if I coudl find my last test map it would a loverly house - daman hdd dying) but it's a nice ghost effect.

Ta.

Hehe...
UQC uses transparency (among other things) in the "Invisible Man" mutator

[Stealth Kill]

If the engine supports transparent water, is it possible to make transparent walls?
