Stay Frosty, Part 9

Posted by SpiceWare, in Stay Frosty 16 July 2016 · 111 views

The prior update stirred up interest in Stay Frosty in the Holiday Cart Forum. Supercat didn't care for how the melt trail worked, to which I replied it was just a kernel test to make sure it showed up on the correct scanline, while atari2600land and vdub_bobby asked for clarification on the planned game play. I clarified that while the ultimate goal woul...


Stay Frosty, Part 8

Posted by SpiceWare, in Stay Frosty 12 July 2016 · 110 views

Thomas Jentzsch and I had a brief discussion about the snowman's movement: Thomas: I'd like the snowman's movement a bit more "realistic" (e.g. with a bit acceleration and inertia).  Me: Hmm, hadn't thought about that. Any sample source you can suggest for me to take a look at?
Revisions to the movement would start a few days later and would...


Stay Frosty, Part 7

The first "playable" build! Collect all the ice blocks then exit the bottom right to the next level. These two levels are in the final game. The snowman controls are a bit odd at the moment, left/right work as you'd expect while up moves you upward. However, if you're not holding up then the snowman will fall unless he's standing on a platform. The m...


Stay Frosty, Part 6

Posted by SpiceWare, in Stay Frosty 10 July 2016 · 77 views

Albert and I had a discussion about the ice and such:
  Albert: I like your idea of disabling auto-melt for nighttime levels. Is the idea here to collect all the ice to clear the level and progress to the next? Why don't the fireballs melt the ice? :) Are the levels going to be differentiated in any way except different layouts of platforms? Th...


Stay Frosty, Part 5

Nathan and I had a discussion about the fire color, nose and melt trail:
 


Color cycling for the fireballs did not pan out, we'll see that in the next update, though the idea of changing color above the ice would eventually be used to great effect in Stay Frosty 2 as seen by these early renditions of the ice chest and carrot:

Stay Frosty, Part 4

Posted by SpiceWare, in Stay Frosty 03 July 2016 · 124 views

I decided to change to use a reflected playfield and drop the updating of PF0 for the upper platforms. PF0's still used to draw the horizon as well as the lowest platform.   Doing this means the snowman can always drop down on the left and right sides of the level. It also adds an additional constraint to the kernel in that you must update PF2 a...


Stay Frosty, Part 3

Posted by SpiceWare, in Stay Frosty 02 July 2016 · 136 views

The following weekend I created a test level to check the update timing for the kernel. The time critical section of the kernel is when the ice blocks are being drawn as everything (snowman & color, nose, melt trail, fireball, 6 playfield updates) had the potential for being drawn:   Looked great, but I had to drop both the nose and the melt...


Static Electricity

Posted by SpiceWare, in Monitor, Treadmill Desk 17 June 2016 · 374 views

One problem that crops up with treadmills is static electricity .  I've experienced it and for the most part the only thing that happened was a small zap when I touch the aluminum frame of my keyboard  - basically I was grounding myself through the USB port on my KVM.
 
With the new 4K monitors I would occasionally experience brief ins...


Stay Frosty, Part 2

Posted by SpiceWare, in Stay Frosty 12 June 2016 · 383 views

Nathan and I discussed the fireballs and nose:  Me (from last time) : Using Missile 1 for the nose means we can't double or triple the fireball sprite - unless they flicker.  Nathan: Hmmm... I think I'd rather do without the nose then. Does that mean losing the nose on the reserve sprite, as well, or just the player?  Me: The nose...


Stay Frosty, Part 1

Posted by SpiceWare, in Stay Frosty 11 June 2016 · 417 views

On October 29, 2007 I was invited to take part in the 5th annual AtariAge Holiday Cart. The plan for the cart to feature a number of mini games with a slick menu to tie the games together. I contacted my nephew Justin for some game ideas and he suggested "You're Frosty collecting stuff" and "You're Rudolf, running away from the other reindeer because the...
