Mixing 2d Sprites and 3D

[Comtois]

yes, it is possible

i changed few lines in the particle.pb example

Works not here.

You need to use DX9 subsystem.

[djes]

This example does not work here.
With directx9 subsystem, in windowed, the 3d seems to be behind a black screen, where's some random transparent pixels (and sometime a big part of the screen) are permitting to see the flares. By removing CameraBackColor(0,-1) it's ok.

In fullscreen, the program is hanging on createsprite(0, 64, 64) (invalid memory access) and we can't come back to the desktop :/
With directx7, the program is hanging on StartDrawing(SpriteOutput(0)) (specified sprite is not initialised), even with changing parameters of createsprite().

[Comtois]

Well, i use subsystem directx9, and windowed mode (800x600).

I can see a sprite (red circle) and particle behind the sprite.

does original particle.pb example work, using directx9 for you ?

Yes, and even in fullscreen.

DX7 isn't supported with 3d-2d mixing.

[Comtois]

i get this, and particle follow the sprite.

[djes]

Here's mine
You see the little dots and the fx behind.

[Fred]

CameraBackgroundColor() with -1 parameter isn't useful anymore as you can't put anything behind the 3d scene. It's now removed.

Ok! Anyway, it still doesn't work in fullscreen, even without CameraBackgroundColor()

[netmaestro]

Works beautifully here in windowed mode but causes an IMA at CreateSprite(0,64,64) in fullscreen. PB 4.3(x86) and DX9, latest beta Sprite lib from purebasic.com/beta/

[Mistrel]

Is it any slower to draw using 2D commands on the 3D screen than it would be to use actual 3D sprites?

[THCM]

Seems to work here. I'll get about 2100 fps.

[IceSoft]

Seems to work here. I'll get about 2100 fps.

How to get the FPS value? Theer is nothing on the source example?
