But, for sure, that "wobbling" on the C64 is suggesting a higher framerate than it is. Link to comment Share on other sites More sharing options...
emkay Posted June 23, 2019 Author Share Posted June 23, 2019 Anyways .... I wonder if the engine could be changed to use Mode 6 with 5 colors and to do some pattern in the characters. Then from the middle of the screen everything gets mirrored and the characters put top down. Link to comment Share on other sites More sharing options...
emkay Posted June 23, 2019 Author Share Posted June 23, 2019 That would mean to have not only colored squares. And the mirroring is only at the screen filling , not in the screen content. Even more interesting: In the center of the screen, half filled chars could be used, and the PMg build the center of the room with a separated color from the border.

Heaven/TQA Posted June 23, 2019 Share Posted June 23, 2019 But why do you want to use chars? xxl did it in bytes yes but why expand on that limited special version? Link to comment Share on other sites More sharing options...

Heaven/TQA Posted June 23, 2019 Share Posted June 23, 2019 The thing with char based textures is that it becomes looking wrong when not doing it correct like raycasters do.... shading is no problem. I used that in Arsantica and one example had highres and 128 dithered chars version of the maze. xxl. Is yours fish eye corrected? Link to comment Share on other sites More sharing options...
Heaven/TQA Posted June 23, 2019 Share Posted June 23, 2019 Look at first “textured” vector object called “stencil” vectors. They look definitely wrong without any Z. Link to comment Share on other sites More sharing options...

Heaven/TQA Posted June 24, 2019 Share Posted June 24, 2019 But that’s not char based but “real” raycaster? what do you want to achieve? I don’t get it. As raycasting is based on collum based rendering based on shooting rays through each screen X pos. Xxl does it for 40x and draws collums in 8x steps... with this you never achieve the look in the video. Link to comment Share on other sites More sharing options...
xxl Posted June 24, 2019 Share Posted June 24, 2019 (edited) I draw using the OS_PLOT function in any graphics mode (OS_GRAPHICS; x40, x80, x160, x320). the scene is drawn with vertical stripes in three steps (sky, walls, floor). The worst are the walls lying close (blocky) but it is the fault of a simpled distance calculation. 280 (x80/x48) Edited June 24, 2019 by xxl 4 Link to comment Share on other sites More sharing options...
+Stephen Posted June 25, 2019 Share Posted June 25, 2019 Incredibly cool demo. Now I'll sit back and listen to the non-coders argue about how they would do it, but they don't code, so they shit on everyone else who does. Keep on, I am watching with incredible interest. 6 Link to comment Share on other sites More sharing options...

And as higher resolution in X you need cos(deltaangle) fish eye correction to fight against distortion. Link to comment Share on other sites More sharing options...

I know I want to have a 3D looking game for the Atari. As much 3D as is needed for gameplay, as less resources using on the Atari, for best gameplay content. HOW characters had to be set , to aid the "3D" projection, would be more clear, if such a engine is running Link to comment Share on other sites More sharing options...

Name it "chance enhancing of possibilities" . Of course someone who has skilled programming knowledege and is interested in creating a game for the Atari, should enter the room. Either people state "it's not possible" or still were not interested , may result in a never ending story Well, particular Stunt Car Racer shows the direction. But that used mode costs a lot CPU cycles on the Atari. As Mode D is always denied , there are those very low CPU using Modes that have been used in Basic. As an addendum to be cleared: There is still the PMg... Edited June 25, 2019 by emkay 1 Link to comment Share on other sites More sharing options...
