fxDecal

#1 can we see a screenie

#2 yes up a screen please, so we can see if this code is something we need or other.
Thanx

#3 A screen shot really doesn't do justice to the way the decal animates.

#4 I'm having a little problem linking this...
main.obj : error LNK2001: unresolved external symbol "class fxDecalManager * gfxDecalManager" (?gfxDecalManager@@3PAVfxDecalManager@@A)
main.obj : error LNK2001: unresolved external symbol "public: __thiscall fxDecalManager::fxDecalManager(void)" (??0fxDecalManager@@QAE@XZ)
../example/torqueDemo_DEBUG.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.

I checked everything and rebuilt everything four times now...
A little help..

#5 Okay, I think I know what happened.

You need to put the fxDecalManager.h and fxDecalManager.cc in the sim folder under the engine.

That should do it, because the fxDecalManager.cc declares the gfxDecalMangager resolving the external declaration in the header.

It looks as if main.cc cannot resolve the external declaration of gfxDecalManager.

#6 Alright, It works now.. Thax

#7 Can we get a larger screenshot?

#8 Would it be possible to add this to precipitation (snow,rain)?
so when it snows, the snow leaves little pools of mud when it drops?

#9 Yes, you could.

But it doesn't behave like a water block, so it depends on what you'd use it for.

#10 I had this working on the Head from around mid March, but the same example in the updateDeathOffsets section seems to make the current HEAD engine crash. As soon as a client connected player dies, the engine locks up. It works the same as before on a single server player connection. I'm not sure what would be different.

Edit: Never mind...I messed up and had the write code section out of place which messed up a couple things. Sorry :( looks like it still works fine on the curent HEAD.

#11 i am trying to get this to work with current head version and get this error
d:\torque 1\torque\engine\sim\fxdecalmanager.cc(122) : error C2065: 'TypefxDecalDataPtr' : undeclared identifier

#12 Great resource. FYI, it works w/ TGE 1.3.1.

#13 Just put this into version 1.3 and it works great. Thanks for contributing this great resource!!!

#14 Works great in TGE 1.3 + TLK 1.3.5.

#15 Got this in ok (no errors) but I get a lot of flickering with camera movement in the decal, i.e. the decal disappears and reappears with left-right, up-down movement.

I first thought it had to do with .dif surfaces, but it does it on terrains also. Has anyone else had this problem? I've tried to find where the decal offset is set, but I don't understand the code well enough to find it. I believe it is just too close to the surface that it is on...I think.

Any ideas would be appreciated.

#16 Awsoome Resource. Finally I have Blood.

#17 Anyone get this to work with 1.4? I noticed most of the initial install instructions don't apply to the 1.4 code.

#18 To get this to work in 1.4 or 1.4.2 these are the changes to the instructions.

In consoleTypes.h in enum ConsoleDynamicTypes right after
TypeDecalDataPtr,

Add:

   //---fxDecal--
   TypefxDecalDataPtr,
   //---Joshua Taylor---

Should read

In consoleTypes.h right after 
DefineConsoleType( TypeSimObjectName )

Add:

   //---fxDecal--
   DefineConsoleType( TypefxDecalDataPtr )
   //---Joshua Taylor---

Then this:

In SceneGraph::removeObjectFromScene add:

Should read:

In SceneGraph::removeObjectFromScene add right after
AssertFatal(obj->mSceneManager == this, "Error, removing from the wrong sceneGraph!");

#19 Additionally, if you want the example to work you must comment out these lines in fxDecalManager:

Con::registerType("fxDecalDataPtr", TypefxDecalDataPtr, sizeof(fxDecalData*),
                     //REF_GETDATATYPE(fxDecalData),
                     //REF_SETDATATYPE(fxDecalData));

Then you must add right above:

IMPLEMENT_SETDATATYPE(fxDecalData)

this line:

IMPLEMENT_CONSOLETYPE(fxDecalData)

I guess you probably just have to do this anyway come to think of it, otherwise it will not work.

#20 Now I am still seeing the problem Alan James had. Has anyone managed to get past that yet?
