Go for it! Then tell me WTF is going on in room 51, it's the Great Reaper. I think I remember it from back in the day too.

in the OP, I state it as 23:59PM EST Jan 20th to avoid confusion on which midnight to use

Last entry for Glider, 193,382 so let's see yours you probably had in reserve, @3lectr1c !

Cascading crashes is the name of my indie prog rock band

Indeed, I knew that but for some bone-headed reason, the emulator spoiled me into concentrating on other problems first. I think I have to go there for good measure, so thanks for once again putting me on the right track. What you propose, main loop only? pass 1: TickCount polled, no events to...

Target platform: real Mac Plus Secondary target platform for quick bug squashing: mini-vMac My project has been real challenging. I've stumbled upon every possible bug, like always, despite avoiding a ton more. But I feel like mastering this brings me significantly closer to my fluid game...

Another bug found: mini-vMac doesn't care if you check if an unassigned PicHandle is nil or not, but the real Mac will give you a address bus error ID=02.

SHAMEFUL DISCOVERY empty out obscure bitmap-like areas before usage, kids. It worked after I filled the space with white. I would like to thank @YMK and @Crutch for their help and patience.

Meanwhile, no problem manually splattering a character all over the alternate screen like so: with this chunk of code replacing DrawPicture(img2,&r); char *paint; //.... //Draw on alternate screen here qd.thePort->portBits.baseAddr = altScreen; //DrawPicture(pic2,&r)...

Hitting a bit of a snag when I'm trying to show the alternate screen's content, it shows up as a really dark screen: Here's my code of a small program simply aimed at testing the technique - I had to look up how to use branch statement with labels with asm blocks in THINK C: #include...

I don't know what this is and I guess I didn't need it since my stuff works! To appreciate how screen flipping can truly help me, I'd need to know common quickdraw function timings. I need help understanding how scenario B helps things: Scenario A: Draw as fast as you can on the main screen...

Ok, lemme get this straight. let's assume X is the number of cycles needed to complete a frame of high speed video game graphics. let's assume V is the number of cycles between vertical blanks of the screen retrace (V being as long as 1 tick, 1/60 th) let's assume X is such that X < V Show the...

This quick code seems to work under mini-vMac, and I assume (!!) on a real Mac Plus as well. I just used the swap_screens() function of the book on p.301 https://vintageapple.org/macprogramming/pdf/Programming_C_On_The_Macintosh_1986.pdf Still got to find the best way to draw something onto...

Let's get it over with: paging @Crutch since I know he has tips inside his mind at the ready, with no need to consult any reference, like always. Goal: I want to prepare an alternate screen buffer graphic a few seconds in advance so I can instantly 'screen flip' at a precise time when needed...

I reached part 2, room 46 and got 162,620, taking the lead for Glider 4.0!

Montage time!

The full 3.8 m (12.5 ft) length of my corner as of Jan 2023 Last pic: finally have a free phone app on Android to take good CRT pictures with 1/70 s aperture thanks to a video from DosFox.

I can see them , might be my cache kicking in. I uploaded them to tinker different, so google has nothing to do with them. edit - under firefox, got a bunch of text garbage instead of pictures. I tried to fix, but it wasn't perfect. I reported my post!
