OK... I have a set of generic GOSUBS for VERA Palette manipulation.

No more updates on this thread. I'm going to start a new thread to post the final set
of GOSUB's.. So its always the Top level Post.

Posted: **Wed Aug 02, 2023 3:32 pm**

OK Tried adding a couple more Routines. They appear to work OK.
and all my numbers seem to be coming out right.

The routine in question is at 40300. I'm trying to achieve a FADE in effect.
The target ends up as meant. But it seems the Actual physical screen isn't
updating until the GOSUB Returns. So I'm not getting the fade in effect I want.
The color just changes to the Target when the GOSUB returns.

This is on emulator R43. I'm about to go try it on the DEV Board and see what
happens.

GREAT NOW MY SD ISN'T MOUNTING ON THE DESKTOP

Ok it appears my SD card reader on my Dell is getting Wonky...

But I got it done and just ran on HARDWARE with the same result...!!
I guess I could have some logic error in my code, but I'm not seeing it.

DOES Anyone have an explanation for this behaviour. ????

THE PROGRAM I'M USING TO TEST

Code: Select all

MooingLemur helped me find the error.
More of my Dyslexia. I had a GOSUB 41000 where it should have been GOSUB 40100

I'm going to update the other thread soon with these new routines. After a
bit more testing.
