Showing a PNG or Decal

#1 Does no one know the answer to this? Lol.

#2 This is quite an old resource.

But my main question is why you're not listed as a SDK owner in your profile...? That's just odd.

Oh well, hopefully the link will give you a good starting point.

#3 I'll second the question about decals in 1.2.2 - there's decals property defined and some code for it. The resource that has been mentioned seems to assume some older version of the code, without support for decals. My question is: is the code that's in current version of the engine working, or is it just some not finished attempt at adding decals? If it works does anyone have some example how is it supposed to be used?

best regards

#4 Just about everything in Torque worked at one point... In most situations, it was used in a single project, then wasn't needed again. You have to remember that the codebase was used at Dynamix for many years in many projects...

Don't the footprints use the decal system?

#5 Yes they do ben

#6 This thread got me interested in trying out if decals work the current Torque version. I was surprised to see they actually work! BUT... the decals are really screwed up. They are in fact just a plane with a texture applied. Becuase terrain is almost never completely flat, they are most of the time only partly shown (some parts are under the terrain). They also flikker a lot (becuase they're exactly placed on the terrain level, i assume more precise video cards won't have the flikkering problem that much, but on my system they flicker a lot). They work better on interiors, BUT... when you shoot on a corner/border of the shape, the decal is placed partly in the air, pretty funny sight if you ask me.
Now, for small decals like bullet holes, this is alright I guess, I mostly experimenting with rocket explosion decals (so size 3 to 7), anything under size 0.5 looks ok tough.
Anyone knows how the decal system can be improved to allow me to use big decals??

Btw, the code:

datablock DecalData(myDecal)
  {
     sizeX       = 0.5;
     sizeY       = 0.5;
     textureName = "~/data/shapes/particles/explosionDecal1";
  };

and in the explosion datablock you place this line:

decals[0]=myDecal;

#7 Is that all you have to change? I con't get it to work. No decals show. Is there something I am missing?

Thanks,

#8 Yeah, that's all I did and they show up just fine. Make sure your decal texture is right, the first time i tried with a white one and that was almost invisible. Then I tried with a black one and that one showed "just fine".

But like I said, for big decals this looks really bad, I would like to see this fixed, and have no clue on how to do this myself.

#9 Look at the shadow code. SceneObject::buildPolyList() in particular. Basic concept is to get the polys that lie inside a bounding box (can mask only for terrain) and then uv the decal across them.

Oops my bad.. i ment the projectile datablock and not the explosion datablock.

Like I tought, way to much for me to handle.

#11 Yeah, I got it working after I put the code there. Thanks for your help. I was pulling my hair out trying to figure out how to get the bullet holes to work without changing the engine again.

Thanks,

thanks for that pointer, doesn't look too bad given that that func already exists. Has anyone else done the dirty work so I don't have to :)

#13 3d Decals Seems pretty cool, but it not enough of an idiots guide for me to even consider it.
