New S3d Library

           
click each image to zoom - in

The mummy is everywhere when I am facing North, South, West etc ... lol .....
Is there a way to put the mummy somewhere in certain coordinate (x,y,z) ?

Haha, it's not as easy as one might think. Basicly, you should render all sprites at the end, sorted from back to front and with full z buffer enabled (S3D_Z_BUFFER). And since sprites should always face the camera, you have to mess about a little with that. I've added a mummy, or atleast the rendering of it, at position 33, 33 (x and z).

The rendering of the heightmap that is done earlier doesn't need to read from the z buffer (therefor I use only S3D_Z_BUFFER_WRITE), since the sorting itself works perfectly for that kind of data.

Edit If you're making a horror game, I totally love those Big Grin Played through Paratopic last weekend (maybe not horror but very ... creepy), completed the original Amnesia games, Layers of Fear, Resident Evil Revelations, Outlast and a bunch of others. But for some reason I just CAN'T play Slenderman, as soon as he appears I go full "NOPE!" and shut down my Nintendo Switch Big Grin I started playing Alien Isolation som years ago, very scary but too difficult so I gave up ... maybe I should give it another go? I'm rambling, sorry.

What! No aliens? Nah... Kidding... Nicely done... All this 3D stuff is WAY over my head... Love playing them but I have no clue as to how they work... But, still cool...

@Marcus
The horror theme in The Maze I and The Maze II is far from creepy such as in Resident Evil, a Scary Teacher etc, but it is more like a "Comedian Horror" or "Child Friendly - Horror" theme... lol  .... No blood splash to your screen, no violence ... only brain seizure if you play the 3D game too long .... lol ....
by the way, I have put " a caution / a warning " before playing the Maze I that "if you have suffered any side effects when playing this game or are concerned that you might be in danger in doing so. Please stop playing and take a rest " ... lol ....

@Johnno 
Alien and UFO in ancient egyptian pyramid ... hmmm... not a bad idea....
I watched the History Channel, The Ancient Aliens ... an expert said that some type of Alien and UFO visited there and helped to build the pyramid ...  Big Grin
