Does anyone have any sample code or something that can show me how to load a sprite in Graphics3D mode as an animation? Somewhat like LoadAnimImage. But with sprites and in Graphics3D.

You can create a quad and add an animated texture to it.It's the same thing with a sprite.

Here's the function to create a quad;

Function CreateQuad(parent=0)

	sprite = CreateMesh()
	he = CreateBrush(255,255,255)
	v = CreateSurface(sprite, he)
	FreeBrush he
	AddVertex ( v, -3, 3, 0, 1, 0)
	AddVertex ( v, 3, 3, 0, 0, 0)
	AddVertex ( v, -3, -3, 0, 1, 1)
	AddVertex ( v, 3, -3, 0, 0, 1)
	AddTriangle ( v, 0, 1, 2)
	AddTriangle ( v, 3, 2, 1)
	FlipMesh (sprite)
	
	EntityParent sprite, parent
	Return sprite
	
End Function

But will it still have the alpha effects and everything? Do I need to have a transparent PNG texture file?

LoadAnimTexture?

@big10p:Thats what I said.But you need a quad you can't texture a sprite.

@Ked:It will have alpha effects with proper flags my friend.

You have to load your textures using, LoadTexture("Yourtexture.bla", 7)

Someone's talking mince again ;)

Assuming a 256 x 256 texture with 8 x 8 texture frames.

MYsprite = createsprite() : scalesprite Mysprite,10,10
MYtexture = loadanimtexture(  "Blah.png" , 2 , 32,32,0,31 )
Entitytexture MYsprite , MYtexture , Frame

Where frame = 0 to 31.

OK then :)

1. createmesh has an optional parent param .. no need to do this manually.
2. mesh color is 255,255,255 by default .. no need to apply a brush.
3. if you create the vertices in clockwise order no need to use flipmesh.

Function CreateQuad(parent=0)

	sprite = CreateMesh( parent )
	v = CreateSurface( sprite )
	AddVertex ( v, -3, 3, 0, 1, 0)
	AddVertex ( v, 3, 3, 0, 0, 0)
	AddVertex ( v, 3, -3, 0, 0, 1)
	AddVertex ( v, -3, -3, 0, 1, 1)
	AddTriangle ( v, 0, 1, 2)
	AddTriangle ( v, 2, 3, 0)

	Return sprite
	
End Function
