Re: Simplest way to swap sprite flames?
Yeah I decided I'd use the engine as some objects will require more animation. I'm struggling to see how to use animations in the sprite demo. I see where they're defined but not how they're implemented. I can write my own using timers and SetFrame etc but I just wasn't sure if that was the 'proper'...

Re: Simplest way to swap sprite flames?
I can't work it out... I can't see in any of those functions where I can change the tile index of my sprite sheet to change frame... EDIT: I worked out how to do it with SetFrame. I was looking in the sprite project and I understand how the animations work (how it runs through each row as an animati...

Re: Simplest way to swap sprite flames?
Cool. I thought that might be slower, like setting your tile map every frame instead of scrolling. I guess im just getting used to how the VDP works. I'll have a play on the weekend. Thanks for your help again!

Simplest way to swap sprite flames?
The sprite engine animation is overkill for what I need. I just want to swap the image of my sprite when I press a joystick direction. What's the best way to do this? Which function should I be calling? I haven't been able to work it out from the docs. Sorry for the super noob question!

A question on palettes/colour cycling
Hi again! Say I have an image loaded that only uses 4 colours and I have a palette of 16. Is it possible to cycle through the pallete colours instead of swapping palettes? I think this could be used for some cool effects. If this is possible, how exactly would it be done? I'm thinking it will be a g...

Re: Garbled GFX when I add sprite
Hehe the joys of classic systems.
Just looking in gens and my flipped tiles are showing up as unique tiles. Is there a way to fix this? By cutting those I'd save half of my VRAM

Re: Garbled GFX when I add sprite
Ok, it turns out I'm running out of tiles. I'm going to have to optimise my graphics. Might cut cars in half etc and flip the sprites. I also just realised that my road image isn't set up properly so the flipped duplicated tiles won't be detected and utilised...

Garbled GFX when I add sprite
Hi again, I have got to the stage where I want to start adding sprites. I believe the VDP handles the tiles for me and I don't have to allocate tile memory like I do with the backgrounds, right? Anyway, the game works fine but when I add the car in, it seems part of the tileset on frame four of my r...

Re: Is there a tool to tell how many tiles I'm using?
Retro Graphics Toolkit can tell you the number of unique tiles in a given image, remove duplicates and even dither to reduce: http://gendev.spritesmind.net/forum/viewtopic.php?f=7&t=1392 It won't work for sprites though since sprite tiles not mapped by ID (unless you keep one sprite per tile).

Re: is a fix32 positive only?
Good point. I'll take a closer look at my code. I could be using a u16 somewhere...Stef wrote:Fix32 is signed but it all depends from your code implementation : having a single non signed comparison can make every thing wrong !
