The Sinclair QL Forum

Hi Folks,
As promised, here is a game to test your reaction speed to the full !
Just UNZIP, LRUN or ESCape, and try to jump over the obstacles to score, ( it beeps to help you).
The allowed reaction time reduces as the game progresses, so it is not as easy as it looks...
If you jump too late you crash, and the game is over, (so wait six seconds to play again).
If you continuously hold down the space-bar, you cheat ! (Let demo=1, on LINE 120 for a screen saver).
You will learn how concentration assists reaction times, as you improve. Aim for a score of 20 or better...

Hi again,
I omitted to mention : Hit SPACE key to jump when you here a Beep ! Steve.

Hi,
Now tested ok on SGC under SMSQ/E and Qdos, but slower than on QPC2... where it whistles along !

No more developments for the next few weeks, due to health problems. Steve.

Interesting graphics! You seem to become the Jeff Minter of the QL

Hi ThorSinclair,
The graphics here were simplified to the extreme, so as not to get in the way of the main job, prototyping the Perspective animation morphing cores.... Soon I hope to get far more realistic output, which just means reading in more data items. The 'horse' uses just five sketches, but morphing interpolates 15 between each sketch.
The actual animation cores are now working fine, so I need to be more accurate with the sketches, which are traced off of photo sequences. The 'horse' was minimalist, to avoid questions of facet-sorting, which will be incorporated at some later stage.
This was all planned in the '80s, but now with QPC2 speed, realtime output makes it all possible..... Steve.

Hi Folks,
BUG REPORT : It has been pointed out that the 'horse' looks more like a grasshopper !
This may well be implemented as standard in future.... Steve.

Hi Folks,
Just putting the finishing touches to a 3D perspective animation of a goldfish bowl, screen-saver ? Tested ok under QPC2.
The prototype will be released shortly, with a version with less 'tropical' colours on the filled facets !
Uses most of the morphing code from 'Galop_bas', with added hidden-face sorting merged in. Will be fully commented.... Steve.

Hi again,
Here is the commented prototype, with better colour for those that have QPC2... (see line 160).
Just UNZIP, LRUN or ESCape.

Hi everyone,
Here is a version which runs OK on SGC , under QDOS or SMSQ/E, albeit slowly.
Fish_bas had a minor parameter bug which corrupted a few SGC screen bytes.... now corrected here.
Colours have been tweaked for monochrome monitors too. Steve.

Hi Folks,
The next challenge was to see if QPC2 could handle many hidden faces in 3D Perspective animations....
So Fish_bas was adapted so that many 'sharks' could be simultaneously shown on screen, although not perfectly smoothly yet.
The prototype demo handles just three sharks at ease, and the release version should be smooth, using less memeory.
The whole animation uses just three simple sketches, the various routines calculate all the intermediate movements.
It is not really intended for SGC or less, but will hopefully use all the power QPC2 offers.
Coming versions should operate using more sophisticated 3D trajectories, a ring being convenient for prototyping ! Steve.
