I ran across this strange occurance about a month ago, and I was
wondering if anyone here could explain the cause of this.
I'm developing a game where I use a clock in the upper right corner of
the screen with 4 sprites. The numbers that the clock uses are of a special
graphics font that I designed and saved as an IFF brush. I loaded the brush in
and proceeded to put a time up like; 2:00. The following appeared; 2: 0
(the FIRST '0' is missing). Others below:
Time What the Amiga shows
---- --------------------
2:00 2: 0
1:59 1:59
1:58 1:58
1:57 1:57
1:56 1:56
1:55 1: 5
1:54 1:54
1:53 1:53
1:52 1:52
1:51 :51
1:50 1:50
Okay, what apparently happens is that if the SAME TWO numbers appear
on the same line, the first of the doubled digit will not appear.
I took the pictures from the SAME memory location, in that:
Sprite[1].posctldata := (example) 1234567;
Sprite[2].posctldata := 1234567;
But, if I copy the data in 1234567 to another location, say 11111,
Sprite[1].posctldata := 1234567;
Sprite[1].posctldata := 11111;
The NUMBERS DO NOT DISAPPEAR!!!!!!! 1:55 will appear as 1:55.
Why when the data for TWO sprites come from the SAME memory location
will the Amiga only show ONE of them?????
