The Sinclair QL Forum

I just tried it on SMSQmulator version 2.31. It displayed a few screens with a pretty pattern and then hit an error:

at line 630:1 Assignment can only be to a variable or array element.

Hi,

The problem is the variable qw at lines 630 - 670, which clashes with Qliberator QW keyword. Changing the QW variable to qw1 allows the program to run on SMSQmulator and QPC2 with Qliberator installed.

I like the program,, but I do not like the use of channels #0,#1,#2, using te Toolkit 2 FOP_xxx function to open channels is nicer way to run a program, my preference.

Hi Derek and All,

Thanks for the 'QW' variable report, (corrected). All screen output now uses #g, (see lines 120 and 3130).

Program tweaked to run under QDOS, so compatibility should be better for other systems ? But does need emulator speed !

Flicker might be reduceable, but at the expense of whacks of memory... for retaining all old morphed positions.

Problem for Marcel ?... POINT 0,0: LINE to 10,10 works ok. yet POINT#n,0,0: LINE#n, to 10,10 fails ; needs LINE#n,0,0 to 10,10 to work....

Hope this is the final version... Steve.

Instead of doing LINE #channel,TO x,y just use LINE #channel TO x,y

i.e. instead of both comma and TO, just use TO alone (one separator)

Thanks Dilwyn,

I forgot that TO in itself is a valid seperator...!

BTW, I never did see any detailed description of all the TK2 instructions. Do you know where they are listed ? Steve.

Hi Folks,
Out of hospital, so here comes Butterfly5_bas... to celebrate my 77th birthday and MayDay ! Steve.

Happy Birthday, Steve!

Now, I just need to find some time to explore your amazing 3D simulations and games!

Hi everybody,
Yer tiz... with flowering buds morphed in in 2D.... Steve.

Hi Martyn,
Glad you like the 3D series of prototype perspective experiments.
I try to keep the code of eacj version constant, so that if anyone does try to see how the code works, it will little change.
The bits that do change , are the few data lines to define the drawings, and some tweaks for animation.
The 3D perspective viewer and the morphing cores hardly change at all. So hopefully, others may be able to do some animations too ?
I have plenty of projects in hand, and thanks to the skill of my surgeon, will be able to continue exploring the subject ! Steve.

I agree, Martyn. High time someone wrote miraculous software which doubles our free time. I'm retired now, expected to have more time, but am busier than I ever was!
