Re: [A]tari [G]ame [T]ools - 2D prototyping engine for STE

Hi,

It uses (Markus Franz Xaver Johannes Oberhumer's) NRV2E/pack2e. I bundle an extra tool called 'packwrap' which just compresses a file with p2e and sticks a size prefix etc. on the front so it can allocate the correct space etc. at load time. :-)

Re: [A]tari [G]ame [T]ools - 2D prototyping engine for STE

[UPDATE] Might as well get this one out of the way - since I already posted a sample video... It is now possible to draw EMS/EMX (fast) blitter sprites using widths greater than 32 pixels. These formats are AGT's adaptations of Anima's fast blitter sprite method (not the very latest stuff, but quite...

Re: [A]tari [G]ame [T]ools - 2D prototyping engine for STE

[UPDATE] The next small improvement is: dual-field sprites It has always been possible to draw scrolling backgrounds using 2 colour fields in AGT (2 images with opposing dither, interlaced @ 50hz to simulate extra colours). But sprites were limited to 1-field, unless you swapped assets manually ever...

Re: [A]tari [G]ame [T]ools - 2D prototyping engine for STE

It does make sense to move it away from Cygwin & Windows generally to get it working natively on Mac & Linux. It wouldn't be a lot of work at my end. But I do want to get some features and fixes finished first. [edit] I mean working on Mac & Linux without WINE - it can be used with WINE currently bu...

Re: [A]tari [G]ame [T]ools - 2D prototyping engine for STE

The next thing you may run into is not finding 'agtcut' or 'rmac' or one of the other tools - so make sure the AGT bin/ directory is on your PATH env variable when the cygwin shell is started.

I think I did put that on the wiki - but it is worth a mention while I remember.

Re: [A]tari [G]ame [T]ools - 2D prototyping engine for STE

Hi Richard, I think it is because the native GCC compiler tools are not installed under Cygwin by default (which provides the 'Make' tool). If you install the 'gcc c++' package - any version - you should end up with make. (You can probably install it with less than that - but I know it works, so...)...

Re: Getting started in ST C programming and boilerplate code / template?

I don't know any C++ so that might push AGT into the future for me, but it looks very nice and tempting! I missed this when it was posted - but in case anyone reading this has similar concerns, AGT doesn't really require C++ knowledge as most of the code you'd be writing is much closer to C. The bo...

While I can't say if/when they will be done, it does seem like more are on the way. At least two of the existing mini-projects are still being worked on. Some were started and paused for various reasons. Part of the problem has been documentation or updates not keeping up on my side (I didn't upload...

Re: Atari STE Blitter objects demo (new record)

That looks interesting. I have a spare PI here with nothing special on it.

I had been using PARCP a lot on the Falcon which is fine for transferring big stuff but was stuck with 720K floppy transfer on the ST/STE (at least, for a TOS1.62 / no-auto-driver solution on the Atari side).

Re: Atari STE Blitter objects demo (new record)

I haven't had much luck mounting this file on HxC - the Atari doesn't like any formats > 720k DS/DD. I can get a directory ok but then read errors loading the image. It may be possible to get it to work but it would probably involve making a custom disk format with the right hardware emulation setti...

Unlucky :( I'm still using the USB version of HxC. So I can just leave it connected to the PC all the time and mount directories from it without moving any SD cards or memory sticks. Unfortunately the software for injecting directories from the host still has some inertia - GUI based, and it always ...

Re: Beginning of very long journey

Just some random comments/scraps from me... Regarding the DSP - and whatever you decide to do there - the mapping of the DSP's host port onto the Falcon bus probably needs to be exactly the same (timing-wise, access-order-wise) if compatibility is to be retained. Partly because it is a significant b...

Re: [A]tari [G]ame [T]ools - 2D prototyping engine for STE

To explain - the 'slab' method was updated to cope with multiple spans per scanline. It is good for big shapes with a small number of large holes. Less so with large numbers of small holes. With the right shapes, it is the fastest method because long spans are not interrupted and only endmasks are u...

Anyway, it's pretty amazing! Are there any cycles left to play with there? Can't wait to see what happens next.
