Re: Change only tile palette

You can't save cpu time like that, it's a word VRAM write no matter what. If you only passed the palette, the function would have to read the word, change those bits, and write it back - being more than 2x slower. Ok, it's logical. I think of that because I also need to change priority. But VDP_set...

Change only tile palette

I wish to change ingame the palette of tiles (planA / PlanB) for showing part of picture. I have one palette with the good color and one black to hide multiple parts of the picture. (never at the same place). So I can only use 2 palettes because I need the others for sprites. And I'll do that with v...

Re: Z-team - Unofficial Port - Ocean Beach Volley, Barbarian (Psygnosis), IK +, ROx Zero

Great work. I love the atari st and his wonderful graph.

The palette of ROx Zero is wonderful.

Barbarian was one of my first game on atari ST. :mrgreen:

Re: Troubles with sprites (new version SGDK)

Reading your code, I realized one thing. There is an issue in the new version of sgdk, Stef will look at it. The sprite engine have some problems when you use meta-sprite outside of the screen. you init your sprite at 350. So, you can add this : sprites[0] = SPR_addSprite( &ufo , 350, 0, TILE_ATTR(P...

Re: Problem change sprite size in game

No, I mean that it was flipped partially out screen then later it showed incorrectly flipped feet. I only use the debug to test the value. I move down the sprite of sonic, use "SPR_setHFlip(sprites[0], TRUE);" to flip and move up the sprite : http://i35.servimg.com/u/f35/18/89/68/64/flip0110.png SPR...

Re: Problem change sprite size in game

I have a question about the spriteengine. I never test it with the old version, maybe it's normal and I need to test with my code. I have a metasprite. I use SPRITE player_sprite "sprite/player.png" 4 8 FAST 5 So I have one sprite (32*64pixels) in my sprites array at value 0 equal sprite number 0 an...

Re: Garbled GFX when I add sprite

I don't know if you post in the wrong place :mrgreen: But for your gfx problem. You have by default a plan size of 64 tiles. So your picture must be 64 tiles * 8 pixels = 512 pixels width. So the last pixel will be drawn at the beginning of your plan over the existing image. You're picture size is 8...

Re: Sega Genesis Dev Kit (SGDK)

I test again and this time directly from the sample sprite whitout changing anything and I always have the same glitch when fading in the top of the screen. If I increase the value of frame of duration fading, it's more visible. I'll try too with async value (false/true) VDP_fadeIn(0, (4 * 16) - 1, ...
