>>>>> PB 6.20 -Bugs <<<<<

[pf shadoko]

version 6.20 integrates the latest version of ogre branch 1 (ogre 1.14.3)
this update posed a number of problems
some are still unresolved (as of PB 6.20 beta 1 release date)

- ScaleµEntity causes a material lighting bug (but it works correctly from the shaders)
- shaders only take into account the first light created (and not the nearest light)
- sprites rarely display correctly

moreover (but these are not bugs) :
- Add3DArchive paths, texture and script file names... are case sensitive
- use of shadows and terrains requires the addition of an Add3DArchive folder

Lets use this thread for found problems for these betas then
I found issue with ConvertLocalToWorldPosition(). For example next code should return the value of 0.0 for GetZ(), but it returns 29.7
Another curious thing is the code hangs at the line of ConvertLocalToWorldPosition() command in PB version 6.12 , 6.04 and may be others

Code: Select all

#CameraSpeed = 0.05

InitEngine3D(#PB_Engine3D_NoLog,#PB_Compiler_Home+"Compilers\Engine3d.dll")
InitSprite()
InitKeyboard()
InitMouse()

ExamineDesktops():dx=800:dy=600
OpenWindow(0,0,0,dx,dy, " ConvertLocalToWorldPosition - [Esc] quit",#PB_Window_ScreenCentered|#PB_Window_BorderLess)
OpenWindowedScreen(WindowID(0), 0, 0, dx, dy, 0, 0, 0)

CreateEntity(0, MeshID(0), MaterialID(0)):Pitch(EntityID(0),30,#PB_Relative|#PB_World)
SkyBox("stevecube.jpg")
CreateCamera(0,0,0,100,100)
MoveCamera(0,0,0,30, #PB_Absolute)

Repeat
  While WindowEvent():Wend
  ExamineKeyboard():ExamineMouse()
  MouseX.f = -MouseDeltaX() * #CameraSpeed
  MouseY.f = -MouseDeltaY() * #CameraSpeed
  ConvertLocalToWorldPosition(CameraID(0),0,0,-30); <- GetZ() should be 0.0
  debug StrF(GetX(),2)+","+StrF(GetY(),2)+","+StrF(GetZ(),2); <- GetZ() should be 0.0
  ;MoveEntity(0,GetX(),GetY(),GetZ(),#PB_Absolute)
  RenderWorld()
  FlipBuffers()
Until KeyboardPushed(#PB_Key_Escape)

I will test some 3D examples on MacOS:

CarPhysics.pb = I can't change the numbers in the parameters next to it.
Character.pb = when moving the camera around the ogre, it seems that the camera or the 3d model starts to shake. (video below)
FacialAnimation.pb = Apparently it's ok
FPSFirstPerson = Line 86 [ERROR] The specified #Material is not initialised.
MaterialScripts.pb = Line: 522 [ERROR] The specified #Material is not initialised.
MeshManualFlag.pb = Apparently it's ok
MeshManualParametrics.pb = Apparently it's ok
MeshMorphing.pb Line: 43 [ERROR] The specified #Material is not initialised.
Pinball.pb = Apparently it's ok
Tank.pb = Apparently it's ok
ThirdyPerson.pb = I don't know what's going on... the character leans to the side as if physics impacted him (screenshot below)
Video Character.pb : https://i.imgur.com/T0Lu0oF.mp4 or https://imgur.com/a/mFoxbkG
Screenshot ThirdyPerson.pb :

[Psychophanta]

In "CreateRenderTexture.pb", after line 65 if you insert (as line 66) : 'MeshVertexTextureCoordinate(0.5,0.5)',
then the code ignores this command.

@ Psychophanta
good idea to gather bug reports here
concerning ConvertLocalToWorldPosition: I'm looking for...
concerningMeshVertexTextureCoordinate: it's not a bug, it doesn't belong here
I answer anyway: MeshVertex contains UV, by adding MeshVertexTextureCoordinate, you specify a 2nd UV that is not taken into account by this material.

@skinkairewalker
the shader doesn't seem to work on your machine
can you confirm this with the examples :water.pb and shader... .pb?
moreover, in your screenshot (ThirdPerson.pb) the ground colors are not correct
can you confirm this by doing a startdrawing test (it seems that the red and blue components are inverted)?

- sprites rarely display correctly

The only thing I found yet is some Z-order issue between sprites and world entities, when the camera is too close to a world entity. (world entity render overlaps the sprite) If needed, I can provide example to recreate the issue.

[pf shadoko]

-ConvertLocalToWorldPosition() with camera : fixed

@miso : I know, if the distance is < 1 unit (we have to remove the dephcheck)

[Psychophanta]

-ConvertLocalToWorldPosition() with camera : fixed

Nice
Be aware when the camera is attached to a node or any. I think the 'ConvertLocalToWorldPosition()' must be based on the world absolute coordinates and world absolute orientation of the object.

[miso]

-ConvertLocalToWorldPosition() with camera : fixed

If nodes become fixed, it would be a very powerful tool for pb.

@pf shadoko
I'm not reporting a bug now, but I dont want to do feature request or pm you, and seems to be the place where I can still address you in this thread regarding the engine3d. I humbly hope I'm not doing something wrong.

- For shaders I can address textures up to 4 shadertextures. Is that enough? Could that be increased up to 8 in the future?
- Is there any way to change the entities visibility mask to cameras on the fly?

Ps:I'm not requesting anything, just asking.

[Psychophanta]

Allow me to post here a request.
It is just an idea, so disregard it if is it not interesting:
Replace 'ConvertLocalToWorldPosition()' and 'ConvertWorldToLocalPosition()' functions by anothe unique:
'ConvertPosition(ObjectID, x, y, z [,Object2ID])
where ObjectID is the source (or -1 if the source is the world, in which case Object2ID is mandatory), and Object2ID is the target (-1 to get the world referred position)

[pf shadoko]

for this version Fred doesn't want to add any new functions, the transition is painful enough!
it'll be for the next one (I've planned some big changes)

@miso :
- MaterialShaderTexture: this function can be called several times, so you can put as many textures as you like
(this should be specified in the doc!)
- I think we'd need a SetCameraAttribute() function with, among other things, the VisibilityMask parameter.

@Psychophanta :
would you like this? :

Code: Select all

Procedure convertposition(objectid1,x,y,z,entity)
  ConvertLocalToWorldPosition(objectid1,x,y,z)
  MoveEntity(entity,GetX(),GetY(),GetZ(),#PB_Absolute|#PB_World)
EndProcedure

here I've replaced objectid2 with entity because for the moment we don't have a general position/orientation function: but the next version will integrate functions like move(obectid), rotate(obectid), lookat(obectid) ...

[Psychophanta]

would you like this? :

Noooo, please don't move anything, just want to know transformed coordinates, nothing more.

@pf shadoko

Thank you for your time. For now, my questions considered to be answered.

[skinkairewalker]

hello all
sorry for the delay

I tested all the ones you mentioned, and as you predicted, examples involving shaders don't work on my Mac, what could be wrong?

StaticGeometry example

StaticGeometry.pb

Using WorldShadows(#PB_Shadow_Additive) decreases the framerate considerably.
Go to 'ground' level and 'move' around - very clear when moving from one side
to the other.
No problem in version 6.1
