3D City Scape + Terrain

    This example is of a 3D city scape that's generated in code.   The example uses the Sprite Entity feature of PB1.7x combined and Draw Perspective Sprite command to render a 3D scene.

PB1.71f TexturedPolyHitSprite Pixels

    This function is more a exposed helper function than a user function persay,  but it's there if you want to detect impacts between a textured convex polygon and a sprites pixels.

PB 1.71f Level Hit Sprite Pixels

    This example is demonstrating the current WIP of the new LevelHitSprite command.   This command allows you to detect pixel level intersections between a sprite and a map (level).  In the picture bellow the test version of the routine is running through and comparing the overlapping tiles + sprite.  If a tile collides with the sprite, the routine internally renders a red coloured rect at this position, so the collision is visible.   Obviously that's just for testing purposes atm.  The routine supports animated and static levels,  moreover the levels transparent tile is ignored during collision.

 PB 1.71f Level Hit Sprite Pixels (Xenon)

    This is a quick follow up on previous update about LevelHitSprite.  Here i'm simply beta testing the command in the standard scrolling demo, my multi camera Xenon 2000 remake.  The players bullets have pixel level collision against the foreground map level.   If a hit is detected the bullet pops the standard explosion anim (see the code snippet bellow).  The interesting thing is that it doesn't really add any overhead at all to the demo's performance.  Which is interesting since the bullet sprites and maps are standard video images.    But anyway, here's another piccy for good measure.

   // From Update Player Bullets function in the Player module

; Check if the bullet hits the front map layer
if LevelHitSprite(ThisMap,1,0,0,ThisSprite)=true
xpos#=GetSpriteX(ThisSprite)
ypos#=GetSpriteY(ThisSprite)
zpos#=GetSpriteZ(ThisSprite)
Add_Explosion(Aliens().TAlien,ThisPlayer,Xpos#,Ypos#,Zpos#,1)
Delete_Bullet(Bull().TPlayerBullet,lp)
Continue

 Simple Xfile Loader - TeaPot (untextured)

       This picture is shows the results of loading a DirectX 3D object file into PB.   The loader is rough as guts and can only load basic geometry as this point.  My aim is just to get it loading 'simple' textured objects.  Which would allow you to explore 2D / 3D combinations a little more seriously.

 Simple Xfile (ASCII) Loader - Dragon (textured)

    The loader has been updated to support textured objects.  It's still not pretty, but they load pretty fast and you can get some 3D happening in your games.  The following pictures are of a simple textured dragon model thrown into the city space scene example.

PB1.68h alpha???its new version PlayBasic? :o

[kevin]

 No, it's a transitional version between PB V1.63 (from back in 2007) and todays PBFX1.74
